Mv Lord Portmax am> (Ikntlemex: In fnltilinont of the wish of the Council of the Swiety, [The Royal Af^ricultural Society of Enj^land,] and in anticipation that I, in common with its menihcrs, shall benefit by the remarks and larirer knowledii^e of others, I have undertaken to appear bo- fore the present assemblage of agriculturists with the view of illustrating some of the principles and rules of jtractice in the art of land-draining. Ry so doing I do not think that I, or others who may follow me, shall be open to the charge of presumption, in- as-much as we may doubt if there lives the man, having acquaintance with the clin.ate, soil and agriculture of Britain, who would have the hardihiwd to dispute the assertion that drainage is beneficial, or the fact that vast districts in our island still require to be relieved from an injurious amount of water stagnant in its soil and stagnating too near its surface. I apprehend, therefore, that I may commence this paper by a.ssuming — by taking for granted — unphilosophical and in- admissible as such a procedure would be in 17 a doubtful case — that land-drainage is an art and a practice of acknowledged value and ucce.«;.sity ; a?id that we arc met here not to dispute about the jiropricty of drain- ing wet lands, but simply to discuss the means of rendering the art of drainage efficient and economical, and to impart to each other our respective knowledge as to the modes of arriving at those desirable ends. I further apprehend that it should be our course to state, with precision, such practice as we may have icverally pursued, it.s effect.s, and the causes to which good or ill-success in a particular practice may, in our opinion, be ascribed. I imagine that we shall, in this way, best fulfil the object of the Council in inviting this discussion, liir I subscribe heartily to the doctrine en- forced in the l^eport of our Council to the general nieeting in .May last, viz.: that "a clear knowledge of cau.se and effect, under given circumstances, and a detail of the particular cases to which such knowledge is applicable, is, in their opinion, the only safe science to be recommended to their mem- bers." There is nothing contained in this declaration of the Council to discourage ex- periment, as has been feared and suggested to me by some of its members — from which circnm.stance, partly, I refer to it — since " safe science," if the term has a meaning 1 268 THE'SOUTHERN PLANTER. [May is simply expressive of that determinate state of knowledge which is founded on facts; and we .cannot obtain facts but through experiments, observation, and ex- perience. Let me mention a definition of science, as propounded by that illustrious traveller and philosopher, Alexander Von Humboldt, in his recently published work, " Cosmos,"* p. 71. He observes, ^'Science begins at the point where mind dominates matter, where the attempt is made to sub- ject the mass of experience to the scrutiny of reason; science is mind brought into con- nection with nature." There is no differ- ence in I he sense of the two definitions, and the recommendation of the Council will put the members at their ease who have infor- mation to add to the common stock, and will, I trust, absolve them and myself from all charge of egotism, or desire of dis- play, in speaking of our individual per- formances or opinions. Experience has proved that a soil sur- charged with water cannot perfect crops, — that excess of water is an impediment to the due mechanical division of the active soil — that it diminishes the fertilizing power of every species of manure — that it lowers the temperature of the mass of the bed- — that it precludes the free entrance and change of atmospheric air— -that it prevents the free descent of rain through the soil, and its timely evacuation. The existence of water in excess is far from being con- fined to those absorbent and tenacious de- scriptions of soil which have obtained the name of clays. My own observation of the soils of Britain leads me to the perception and belief, that fully as large an area of its extent, consisting of loams, and of earths still more silicious, need draining quite as much as the stiff and compact clays. Water is permanently maintained too near the surface of many soils, where natural texture, for a few feet deep, would allow to it a free pas- sage downwards, were it not for the exist- ence of a clay or some other impassible medium, at a depth more or less great, which uphold water. The evils referable to the excess of water in soils arc rendered pecu- liarly apparent by comparing such water- logged land with those free, deep, naturally dry, and warm soils, as they are called. •"Cosmos; A General Survey of the Physi- cal Phenoniina of the Universe." BaiUiere,219 Regent Street, London. which are so coveted by fiirmers; of which every one wants a slice, but which arc §o rarely to be met with, in comparison with the over-wet or too dry portions of the superficies of our island. The art of draining land is to assimilate the naturally wet to the naturally moist soil, in so far as that can be~ accomplished by so simple an operation, and its eftect upon the physical condition of wet land will be the greater or less, according to the knowledge and skill displayed in per- forming the operation. In a former paper on the subject, entitled "On the Influence of Water on the Temperature of Soils," (See February and March numbers of this journal,) I endeavoured to bring together and lay before the Society a succinct history of the properties of water in its several states as a fluid, a solid and a vapour or steam, and to show its efi"ects upon soil ; to- gether with the action of other natural forces inherent in soil, and dependent on meteorological phenomena. I need not again refer in detail to the points discussed in that Essay, nor further than to express the conviction, that without a pretty clear knowledge of the nature of those bodies, forces, and phenomena,— without, in fact, in- forming ourselves of the properties of the tools with which Nature works, our own efi"orts and performances must be imperfect, and come short of the mark. A number of instances of draining, ob- served at diff"erent periods, and published by others as well as myself, has induced in me a firm belief in a very early-formed opinion, that, the general drainage carried on in this country, is of a depth too shallow to realise the valuable results which a given expendi- ture of money is capable of effecting. Grow- ing experience, with extended observation, have only served to strengthen my confi- dence in the superior efficiency of a deeper system of drainage, and the fortuitous dis- covery of the simple cylindrical pipe-con- duit came in aid of those agriculturists and drainers whose convictions and practice are enlisted in the same cause. The Society owes to Mr. Pusey the first announcement, that there were drain tiles of that form in use, in his paper "On the Evidence pf the Antiquity, &c., of Thorough Draining," published in the May Journal of 1843; and in the same year, at the Derby Show, Mr. John Read exhibited a few specimens of pipes. This was followed by an investi- gation into the use and merits of pipes ^.^Hfl I860.] THE SOUTHERN PLANTER 259 Bftde at the instance of the Council by | of whose u. m 1; \v.i> printed in the year 1 052, myself in Kent, and reported in the second and in which the recommendation and theory part of tlie Journal of tijc same year.

Beds of gravel, sand or mix- ed earth also often prevail under superficial clay at depths not too great to enable the drains to be placed at distances considerably wider apart than if the drains were laid in the clay, effecting thereby the removal of the subterranean water, permitting the de- Bccnt of rain-water, and causing a less out- lay of money. • The capillarity, or sucailmci/, of soils varies and is often very noticeable. It has occurred to me in digging test holes previous to drainage, to find the water standing in them not nearer the surface than three feet, yet, the surface soil has been so wet that water would drop from it on squeezing it with the hands. This ex- 1 hibition would determine me to bleed such soils to the depth of five feet at least, a' d ' Fuch drainage has been accomplished with ' complete success. * ! Although I am not a practical farmer, I ^ think that I may very confidently recom- mend to farmers the laying land absolutely flat after efficient drainage. It is the prac- tice of many good agriculturists in the stiff- est clays, who consider that even a crea.«5e left on the surface is injurious to drainage. In addition to several received opinions on that head, I will quote a letter recently re- ceived from Mr. Andrew Thompson, the intelligent bailiff of the Right Honourable Charles Arbuthnot, who has drained part of his farm — a very strong clay — four feet deep, and whose account of the effects is to be found in the last Journals. Woodford, July 4th, 1846. Dear Sir : On the arable land which we have drain- ed to the depth of four feet, I have not found it necessary to maintain any open waicr-furrows. 1 am not at all an advocate for water-cuta or surface drains of any de- scription on arable land, it being my belief, that, when they are used for the purpose of carrying off the water after heavy rains, they are also the means of washing away a quantity of fine soils, which might other- wise be retained on the land. 1 believe, that, if even the most retentive of soils were drained to a considerable depth, and ren- dered Triable by the aid of Read's Pulver- izer, there would not then be any use of open water-furrows on that description of land. In reply to your other question, I have to say, that adjoining one of the fields which was drained to the depth of four feet in a field of the same subsoil, (a strong blue clay,) which was only three years ago drained in the old-fashioned way of " shal- low draining," I have frequently observed that after heavy rains tke water began to run first from the deep drains, and that, when the shallow drains did run, they did not appear to me to discharge the same quantity of watef to the Siime quantity of land as the deep drains. I was quite against draining land so deep until I saw the great advantages derived from it. Yours, &c., Andrew Thompson. The last remark made by Mr. Thompson, as to the deep drains giving issue to rain- water, in land under precisely similar cir- cumstances, before shallow drains, agrees with the observation of a great number of farmers whose land has been so drained ; and it would be difficult to cite a more ap- posite proof, I think, of the superior con- dition into which the mass of the soil is brought by deep drainage. That this should occur in a field where shallow drains exist in the neighbourhood of deeper drains, and within their influence, would be naturally expected, as the water keeps on 264 THE SOUTHERN PLANTER [May descending below the level of the higher and until it reaches the level of the lower vents, where it meets with free water, and then begins to travel horizontally to the drain. The reason, however, why the deeper drain in one field should begin to discharge before another and a shallower drain in another field or in a very distant part of the same field baying pr(^ciseiy sim- ilar soil, is not quite so obvious. I have this day received from a tenant farmer in Yorkshire an account of an ob- servation of his,, that a four feet drain began to run five minutes earlier after rain than another drain 16 inches deep, at a distance, but in the same field. Some experiments are being made which may elucidate this action, which tells so favourably for the deeper drainage.* There are some causes of stoppage to subterranean drains, though fortunately few and limited in their extent, with, which every drainer should be acquainted, and prepared to encounter and vanquish as he best may. The first and most extensive evil of this kind to which I will refer is the deposit of a substance of an unctuous sticky nature, in drains laid in soils contain- ing much ferruginous matter. Oh this point I was particularly questioned by his Grace the Duke of Richmond, Chairman of a Select Committee of the House of Lords, appointed last year " to inquire into the expediency of a legislative enactment being introduced to enable possessors of entailed estates to charge such estates with a^um, to be limited, for the purpose of draining and otherwise permanently improving the same." I was asked, '^ Do not stone drains invariably clog if there is water in them impregnated with iron ?" My reply was, " I have no doubt been practically and specially required to discover the cause, and, if possible, a cure for this disease. It may not be thought tedious that I narrate what I know on this subject, as there are thousands of acres of land subject to this evil, the drainage of which depends on discovering some means of rendering it permanent. When applied to by Sir Robert Peel last autumn to drain some portion of his estates at Drayton Manor — and he knew that my system consisted in the use of small pipes in preference to any other conduits — he earnestly called my attention to this cause of stoppage, which had been a continued source of vexation, expense and defeat, in draining the park and other parts of the property. Sir Robert accompanied me throughout the grounds to be first drained, and showed me the evidences of this red deposit at the mouths of drains, and the spewing masses of it on ditch-banks, &c., leaving me to deal with the enemy accord- ing to my judgment. . It will be conceived that I felt tlijs full force of the difficulty, and there was but little experience, so far as I know, of the use of small pipes in soils similarly infested. Yet, I had confi- dence in pipes as preferable to all other con- duits, from the compression of the run of water into the smallest required volume, and therefore as more likely to prevent deposits from occurring or accumulating in them than in larger conduits. I was acquainted with one case and only one in which my small pipes, an inch" bore, had been used, and have continued to act well for several years. without obstruction in a boj :gy s< oil charged with iron, though the ditches into which the pipes, always running full bore, their water, require clearing discharged but that the ferruginous matter, such as I [once or twice a year to keep them open. I have often seen accompany the water ofi also felt additional confidence in the suffi- drainage, would stop up stone drains;" and, jciency of small pipes, as I proposed laying in .conversation, his Grace informed me, them with collars, which would further help that he had estates in Scotland infested to;to cover and diminish the size of the crevice such a degree with ferruginous matter, that; between each pair of pipes, and close it the deposite of iron in drains seemed an 'against the entrance of solid matter.

[May into knots, and berthed in a nidus, formed by the side of the vertical bore, and in com- munication with it by'a lateral hole about an inch long, forming in appearance a com- fortable retreat. 3Iy valued and much lamented friend, Mr. Henry Handley, informed me of a piece of land near the sea in Lincolnshire, over which the sea had broken, and killed all the worms — the field remained sterile until the worms again inhabited it. He also showed me a piece of pasture land, near to his house, in which worms were in buch numbers that he thought their casts inter- fered too much with its produce, and in- duced him to have the field rolled at night in order to destroy the worms. The result was, that the fertility of the field greatly declined, nor was it restored until they had recruited their numbers, which was aided by collecting and transporting multitudes of worms from other fields. The great depths into which the worms will bore, and from which they push up fine fertile soil and cast it on the surface, has been admirably traced by Mr. C. Darwin, of Down, Kent, who has shown that, in a few years, they have actually elevated the surface of fields by a layer of fine mould several inches thick, thus adding to the pab- ulum of the grasses. His experiments were made at Mr. Wedgwood's, of Etruria, and are recorded in the ' Gardener's Chronicle ' of April 6, 1844. Mr. Darwin's researches are entitled to the strictest credibility. Here, are some specimens of warp soil now under- going drainage by me on an estate of Mr. William Marshall, M. P., near Patrington, fourteen miles east of Hull, and opposite the well-known tract of land, reclaimed like- wise from the Humber, called Sunk Island. When first examining this soil for drainage, I was struck with the astonishing number of fine vertical holes penetrating the warp to its full depth — in some places eight to ten feet. These holes evidently were not the work of earth-worms, being of a much smaller bore, and worms abound in that soil, ami were at work in their own fashion, though no other living creature was dis- cernable. Very many of these minute holes seem to be fully appropriated by the fine roots of plants, which descend into them, and thus find easy access to moisture and air. On further investigating into the origin of this net-work of holes, it was traceable, beyond a doubt, to the existence and activity of myriads of small marine animals, having numerous legs, and minute, eel-like looking fish, working in the mud of recent depo- sition. The tidal stream from the Hum- ber, which is conducted upon the warping grounds, and let out again with a retiring tide, after the deposition of its solid matter, does not destroy the life of these creatures, nor close their cylindrical habitations. On the retirement of the water, they are to be seen ceaselessly occupied in working up and down their holes further, to maintain and elaborate them against the next invasion. The death of these amphibious animals no doubt occurs when the process of warping terminates, and the soil solidifies, but their holes remain entire, and open from the top to the bottom of the mass, serving to admit air and moisture, and to pass the water of rain in finely divided streamlets to the drains; and the earth-worm finally estab- lishes himself in a soil easily penetrated, and most congenial to his mining habits. In the field of warp first begun to be drain- ed on this estate, I have set out the drains at about 40 feet asunder, their depth vary- ing from four to six feet, as outfall permits ; but it is probable, as experience is gained of the draining faculty, that we may see fit to diminish the number of drains, and so in- crease their distance from each other in these soils. The alumina of the Humber warp is very fine and very retentive of moisture. Water appeared at 18 inches be- low the surface, after a month of powerful evaporation and drought in May and June of this year, and copious streams were dis- charged from the deep drains. In its origi- nal state of wetness, but under circumstances of drought, this soil cracks widely and deep- ly, like the stiffer clays, so that it seems to possess every facility for the most complete drainage, whilst its faculty for absorbing moisture from the air, and by capillary at- traction from below, are of the highest order, which must vastly aid in conferring upon it the fertility well known to attach to warp lands. But as the quality of warp varies greatly, according as the deposit takes place in dif- ferent parts of the same stream, and at greater or less distance from the warping river's mouth, I cannot, perhaps, mention a more remarkable instance of the difference in the properties of warp than what occurs at Bridji-ewater in Somerset.

These cess-pools, with the various pipes now exhibited, have been made by Mr, J. M. Hoskison, of Wilnecote, near Fazeley, Staft'ordshire. They arc adnjirable speci- mens of manufacture fur truth and smooth- ness. It will be observed that I have not intro- duced to your notice any other kind of drain-tile than pipes, and because I con- sider them to have the preference over every other description of drain tiles, and for the following reasons : — 1st. Ik'cause the pipe is an entire con- duit in itself, stronger than any other lorm, and capable of being centred and con- nected by collai"s, or of having one pipe i sheathed within another. : 2nd. Because the pipe requires less sub- stance of material for a given strength, than any other form into which clay can be put. 3rd. Because the carriage is lighter, both to the field and in the field : a great con- venience and economy to the farmer and the drainer. 4th. Because, from their form, when properly laid in the soil, pipes are subject to less derangement from external pressure, or the entrance of earth or vermin, than other forms of drain-tile heretofore in use. f)th. Because a less amount of earth has to be excavated in forming a bed for the cylindrical pipe, at a given depth, than for the common tile and sole. Gth. Because pipes can be laid truly and firmly on their bed, whether plain or with collars, without requiring the workman to stand in the drain. Much has been said and written about the porousness of pipes as a useful property. I do not see any reason to suppose that the pipe possesses any greater or less degree of absorbent power than other porous or un-j glazed earthenware, most of which are more or Ie>^s porou.s to water. When properly ttsted under a pressure of four feet of soil, 1 have found the ab.sorbent power of various pipes, formed ol' various clays, eijual to the pa.-.sing of about lol.Oth part of the quantity of water which enters the conduit through the crevice existing between each pair of pipes. By so much tliis proj)erty is useful, and 1 do consider that it assists in drying and giving firtiiness to soil in immediate con- tact with the conduit. The tools which 1 now exhibit are, I be- lieve, of very superior manufacture, and much cheaper than many inferior articles made about the country. They are tho result of much care and trial in comparison with others, and of cost to myself and the maker, Mr. Lyndon, .^linerva Works, Faze- ley-Street, JJirmingham. Here are speci- mens of the various grafting tools, scoops or hoes of different sizes, and the all-inij)ortant bottoming or deep-drain spade. A principal advantage in these, as compared with other maker's manufacture, is, that the steel of the tool is plated upon iron so that, as the iron wears 'd\vi\y, the steel maintains a con- stant sharpness of edge, and the drainers have not to run away from their work to the grindstone. The pickaxes, &c., arc of equally good quality. Here is a tool, called the pipe-layer, recently invented by one of my men for layin.^ '^ pipo •'I'^d collar-joint at the same time into a drain. This simple contrivance has saved the u.sc of a boy in laying pipes wl^en collars are necessary. It is suitablejlbr pipes of li inch bore, but may be made to suit any other size of pipe. With reference to these practical matters, it may be advisable for me to s;iy that, in clays and other clean-cutting and firm-bot- tomed soils, 1 do not find collars to be in- dispensably necessary, although I always prefer their use; but they are essential to the security and permanence of drains in sandy, loose, and rofk atrat^i. • JOSI.MI I*ARKF.S, 11, Grrnt Collrge Street , Westminster.

[May Address of Hill Carter, Esq. Delivered before the Virf/niia Central Agri- cultural Societij at the Fall Eihihition of 1859. Gentlemex op -the Va. Central Agr'l Society and Fellow-Citizens of Virginia : Having been requested to address this Society on the subject of practical agricul- ture, and give a description of the Shirley Farm, and management upon it, I rise with unaffected diffidence to address so large and brilliant an assemblage, fearing that I shall afford very little pleasure or profit. But, believing it the duty of every one, when called upon by his fellow-citizens, to con- tribute his " mite/' even should it be as small as the " widow's mite," I will en- deavour to respond to the call, so flattering- ly made upon me, and I only regret my feeble ability to make a proper return lor so high an honour, and to give instruction and entertainment to this large assemblage. As I am merely a plain farmer, I will in a plain farmer-like way, give the experience oi' one who has lived and worked some forty odd years upon a farm, and raised and educated a large family from the proceeds of the farm, and that farm, too, when I commenced, worn out and exhausted, as nearly all the farms in the lower country of Virginia were at that time. The great drawback to the improvement of Virginia agriculture is the high price of labour, in consequence of the high price of grant, if exerfed in Virginia^ would enable him to enrich his farm, to enlarge his es- tate, and perhaps to rival the most prosper- ous emigrant to the West. I do not deny that large fortunes are fre- quently made by emigrating to the West, but my friends, it is frequently at a great sacrifice of comfort, feelings, family ties, and sometimes of principle, too, for it can- not be denied that the principles of new countries are looser than of old settled coun- tries. Nine times out of ten those emi- grants who succeed in the West, would have succeeded at home ; and those who fail in the West would have done certainly no worse at home, and perhaps bettor. So my advice to those who have tolerably f\nr prospects at home, is to remain and use proper exertion to improve their lands, their circumstances, and their mother State ; and ^ the first thing necessary to do that is, to j follow the example of emigrants to the West in these particulars, that is, to use economy in living, dress and furniture, until they shall have made a fortune, and never to in- dulge in any extravagance until they are perfectly able to afford it. Travelling out in the AVest, the plainest fare and furniture are met with, even in rich planters' houses in the country. The cotton bale and the sugar hogshead are the standards of wealth and respectability there, and although that thing may be carried too far, yet if we were in Virginia to think less of high living, and more of cropping, there would be less occasion to emio;rate. It is a singular fact, negroes, and the great temptation to our but certainly true, that a man who in Vir- population to move off to the rich lands ofiginia is accustomed to live at his ease, and the West^ and South-west, where lands are ! in luxury, will go out to the West and set- tle down in a log cabin, eat corn bread and middling, work hard, and save every dollar he makes, that he may buy negroes to make cotton or sugar, and the ultimate fruit of all his privation and toil is, to die a wealthy man. The same man, if he were to live j I and save in the same way in Virginia, and work as hard, might increase his wealth perhaps just as fast, and die rich, too ; but owing to the old habits and associations prevailing in his neighbourhood, he will idle his time, live above his means, waste his substance, and at last die a bankrupt. One of the advantages of emigrating to a new country is, that it certainly gives en- ergy and economy to some who are deficient cheap and '•productive, and fortunes easily made. This has taken off both our wealth and population, and retarded the improve- ment of Virginia. It is a strong tempta- tion to a young man living on a poor farm in Virginia, who hears of the fertile lands of the Valley of the Mississippi and in the new States of the far West, to emigrate, hoping to make a fortune in a few years ; but he little knows the trouble, the difficul- ties, the dangers and risks he encounters, and after all he very often draws a blank in the lottery, (for such it is,) in which he en- gages, and instead of bettering his situation, he is worsted, and sometimes ruined. The same energy and industry, the same intelli- gence, perseverance and enconomy which are necessary to the success of the emi- n these qualities, and I dare say it would be good advice to such to emigrate^ for it gives I860.] THE SOUTHERN PLANTER. 273 them a new character; but, if we could buti retain ainon^ us the energetic, the iiit lli- gent, and economical part of our popula- tion, Old Virj^iniu would be ns prosperous and flourisliin^r as any State in the Union AVe have a ^'rcat variety of climate and Boil, and only want industrious and econom- ical habits in our farmers and planters, and the application of more care to the improve- ment and to the beautifying? of the land, and less to the pamporinir and beautifying of the body, to make Virginia the first State in the Union. Now, the next (juestion is, how shall we improve the land in \'iri::inia ? For all will I admit its want of improvement. In the first place, cultivate only as much land as can be done judiciously. Turn out the balance to pasture, or to ^ow up in woods if you cannot cultivate it well. If the land is poor or exhausted, adopt an amelio- rating system, introducing gra s frequently where you cannot command manures from cities, &c., or if your capital wil! not afford it. Grass is the great renovator of land in our arid climate, and without it, unless you can command manure from cities, or els(r\vhere — an advantage enjoyed but by few — there are no means of iniproving worn-out lands. The next question is, what grass is best adapted 10 our climate and soil generally? I would s;iy, red clover, — though any other graijs that you can get to grow is ameliora- ting. Yet clover is most valuable, most usual, and is quickest introduced into our lands. But some will perhaps say, that, my land is too sandy, or too much of a pipe- clay to grow clover kindly. Well, that is unfortunate, but there is a remedy for this evil. Peas will grow well on sandy land, and next to clover the pea is the best im- prover I know of Sandy land is al.^o more easily and economically cultivated, and therefore profitable, l^ut for pipeclay, there is hardly any remedy that will not cost more thin it will repay, but yet it can be improved at high cost, and many of us who have small strips of it running through our lands, have to cultivate it at more cost than profit, merely becau.se it would be an eye- sore to leave it unimproved. Plenty of lime and manure frequently repeated, mi>kes pipe-clay yield good crops of wheat and clover, and tolerable crops of corn, but the same quantity of manure and lime applied to other lands, would go much farther, and be much more profitable and economical. 18 In fact, if the pipe-clay lands lay in a situ- ation to turn them out to grow up in woods, it would be the be.>st u.sc you could make of them. In an economical point of view, they ought never to have been cleared, but they are freijucntly mixed uj) with t e besi lands of our country, and we are compelled to vlear them, and work them though they do not pay — or disfigure the plantation bj leaving them out. As to an ameliorating system, the ques- tion arises, what sysfem is the best ? J his depends upon the nature of the soil and climate, whether it is hilly and rolling, or a flat country, whether a light or stiff soil ))revails, or whether there is a mixture of sand and clay, i^'C, and whether the climate is cool or hot, Jkc. Now, I should say, in a hiJly and rolling country, the best system is, frccjucntly to introduce in the rotation of crops the grasses — clover, timothy, blue- grasa, or any other adapted to the soil and climate. It would be advisable, also, to have many shifts. Six, seven, or eveo eight, would not be too many. But in a flat or alluvial country fewer shifts, or fields would answer The rolling, hilly country requires grass more frequently, to prevent the .soil and manure from washing away, and is generally, both in climate and soil, better adapted to the production of grass, with which grazing for market may be united ; whereas, the flat or alluvial lands are not so good for gra.ss and are better for grain — corn especially — and are less adapt- ed to grazing for market. Rich lands will, of course bear a more vigorous system, re(|uire fewer shift.s, and bear more freijuent cultiva- tion, and of course make more profit. The best lands in our country, both hilly and rolling, or flat and alluvial, are very much of the same nature, (with few exceptions,) for the reason that the alluvial lands of our rivers were formed from the be*t soil of the moun- tains and upper country washing down and forming the alluvial deposit of the rivers below. The best soils of our country are of the happy mixture of sand and clay, with just enough iron in them to give them a good brown chocolate colour, then if they have veg- etable matter enough, together with the pro- per salts and lime in them, they are perfect. The next best lands of our country are thase which approach nearest to the fore- going, either red or mulatto, having a pro- per proportion of sand and clay. The third best are what are called grey ; having 274 THE SOUTHERN PLANTER. [May little or no iron in them, but a good mixture of sand and clayt The poorest are the pure white lands always excepting the pure pipe- clay, the unkindest land of all, which is only profitable in timber, and should never have been cleared if it could have been avoided. There are a great many grades of land between the foregoing, such as red clay land, red sandy land, mulatto clay land, mulatto sandy land, coarse sandy land, and gravelly land, black sandy land, and boggy or peat lands, but they all have more or less sand and clay in them, and the nearer they approximate to the happy mixture of these elements the better the land. Wherever the happy mixture of sand and clay pre- vails, the land is very easily improved with clover and plaster of Paris, — particularly if there is some lime in the land. All clay lands, in a cool climate, are good grass lands and may be improved with grass and rest. Even in a hot climate, grass will grow tolera- bly well on clay lands with manure and rest. What I mean by clay lands, are those in which clay predominates, though not without some sand. Indeed, all lands have more or less sand. " Limestone" lands are good all over the world. But to return to the proper system >for ameliorating lands: I should think t.hat in a hilly, rolling country, seven or eight shifts with grass, at least three years in the rotation, would be advisable, with graz- ing for market, or tobacco, if in a tobacco country; but in a flat or alluviaL country, fewer shifts — say, if exhausted, five shifts — with grass two years in the rotation. If in good heart — four shifts — with clover one year in the rotation, and tobacco or not, as the country may or may not be suited to it. These rotations, of course, should be regu- lated according to the strength of the land; rich or strong land requiring fewer, and weak or poor land requiring more shifts, and a more frequent introduction of the grasses. If the land is too sandy for clover, substitute peas in the rotation, and give it more rest to put up in natural grasses. Of course, in all systems, you should make rind use as much manure as you can, and where cities or towns are accessible, you should , procure manure from them — if you have the means, — and where lime or marl is to be conveniently procured — if the land has not already lime in it — it should mostcer-! tainly be used, as there can be no permanent improvement of land deficient in lime, with- out the use of it. It is said, and I believe truly, that there is no lime in the soils below the falls of our rivers, except the Indian banks, or deposits of shells, &c., and cer- tainly these soils are more benefitted by the use of lime than by any other manure that has been tried upon them. Both sandy and clay lands, hilly and flat lands, are improved by lime in the tide-water country, and we are all very much indebted to Mr. Edmund Rufiin for the introduction of the use of marie and lime. His book on Calcaneus Earths is, in my opinion, the most valuable book to the tide water farmers in the world. I sincerely believe that but for the use of 1 marie and lime in the lower country it would have been deserted, and become a wilder- ness. But with the proper use of them, I believe it will become one of the most popu- lous and desirable sections of the State. Next to an ameliorating system, comprising the grasses, and manure, lime, guano, &c., utensils— -good ploughs, come good farmin< good strong and heavy harrows— -particu- larly for stiff lands; good reapers; thrash- ing machines, according to the labour re- quired, &c. There is no economy in using indifferent implements because they are cheap. Next to these come good teams, mules, &c., (and at the present prices far- mers ought to raise their own mules. Why should we not raise our mules as well as our negroes?) I said good teams: I mean quick, active mules, or horses. A slow mule makes a slow ploughman, and besides losing time — for time is everything — a slow ploughman makes bad ploughing, for a plough will not do good "■'irk going along in a snail's pace, and you are, moreover, feeding man and horse to little purpose. Next come good and well trained labourers and good over- seers — the two most important parts of the whole system— -and how to make them so is the question. Well, the question has this solution : Close and strict attention on the part oC the master, good discipline among the negroes, good feeding, clothing, housing, and nursing of them when sick, make good labourers and good overseers, I never had a bad overseer in my life, and I have had a great many. Some of them have been said to be bad before they came to me, and after they left me, but they have always behaved well while with me. They say, on board ship, a good captain makes a good first lieutenant. I think the negroes and overseer depend very much upon the master. An attentive master makes good I860.] THE SOUTHERN PLANTER. 275 overseers. I found tlic land in three hliif'tn, corVy n/icaf, and ptisfurc, with some indiffer- ent cattle, and .sheep, and a few hogs, all ^razini: the third field, ^o as to make the third t-hilt, and what was called the resting }ear — the most exhaust inu,- part of the sys- tem. I was young — not heing of age— and just from sea. Of course I knew nothing about faiming, but I soon saw that there was a want of system in everything — no regularity of hours, no measuring in and out, no day-book, no journal, no reckoning kept. It was so different from sca-.serviec that I began to fear the ship was in a bad way, and would soon founder, if not at sea, at least on the river. So I began to inquire and read some little about farming, and Ibr- tunately met with the rhiladeli)hia Agricul- tural Memoirs, and my old i'riend John G. Mosby, who, by-the-by, is entitled to the credit of introducing the four-shift system and clover on lower James river. 1 soon found that land could be cultivated in other ways than three shifts, and that the whole system was wrong; and in a year or two I count of incomings and outgoings, have all I changed overseer and system both. The his crops regularly measured in and out; i first change I made was to turn out the keep an accurate account of all farm ex- poorest field, and convert it into a standing penses and profits, A:c., and balance ac- pasture for the cattle, sheep, &c., and laid off the other two fields in lour shifts or fields, and sowed one each year in clover, and plastered the clover heavily; the clover and plaster acted finely, and the crops im- proved rapidly under the milder system of four fields and a standing pa.sturc for the stock, which allowed all the clover to be overseer and good negroes. The next question is, will the system recommended pay? Good, or improved land, good ma- nuring, liming, itc, good teams, good labourers, giH)d farming utensils, good over- seer, everything good must cost a great deal of money, but bad ones, my friends, cost morel 80 it is cheaper to get good ones. Improved land certainly will make more than unimproved. Good labourers, utensils, &c., require fewer of them and will be cheaper in the end, so there is true economy in having everything good. If you have stock on your land, you should select the best breeds, for it is as cheap to feed good Btock a« indifferent, and much more profitable. Every farmer should have cattle enough to afford him oxen for farming purposes, and to convert his straw and stalks, &e., into ma- nure, even if he do not graze for uiarket, hogs enough to feed his negroes, and sheep to clothe them if he is in a jrood grass conn- ed o try. Every farmer should be systematic in everything, should keep a journal, or re- quire the overseer to do so, keep the ac- counts at the end of every year, and then he would know whether the firm was mak- ing a fair profit, and whether he ought to remain in Virginia, or emigrate. I have said nothing yet about rocft crops; but although the lower country is not a very good root country, there are souie roots that can be raised, in a small way, to advantage; | turned in, the cattle not grazing the clover for several years, until the land acquired a sufficient quantity of vegetable matter — the very thing it most needed after so long and scourging a system as it had undergone for Viany years.

I continued about myself, as I should have to do, if I the live-field system, with partial grazing, went fully into detail, I will only make a | for several years, with tolerable success, until few remarks on that subject. In 181G Ij Mr. Edmund lluflin induced me to try the took possession of a poor, exhausted James marl from his farm in Prince George county, river plantation, which had been originally which acted like a charm. I continued the good land, but very much exhausted by bad | use of marl for several years, but finding it culture, under the management of ignorant' very laborious to transport, it being across 276 THE SOUTHERN PLANTER [May the river, and eight or ten miles oif, I com- menced usinp: lime; first, by buying oyster shells and burning them in a kiln ol* wood ; and after oyster shells became difficult to procure, I commenced the use of Northern lime, and have continued it ever since, m moderate quantities, liming regularly one shift or field in the rotation each year. The improvement from clover and plaster of Paris alone was considerable, particularly upon the wheat crop; but the land began to get clover sick, and frequently failed to produce good clover, and of course the wheat crop sufi'ered, ibr they go together, but after marling and liming, the clover rarely failed, and the crops regularly improved, particu- larly the corn crop, which has doubled since marling and liming were introduced, and both wheat and corn crops have quadrupled since 1816, when the three shift and hard grazing system was abandoned. I attribute "whatever success I have achieved to constant and strict attention to my business; to my lands, negroes and overseers; to a systematic habit I acquired at sea, of keeping regular account of every thing on the plantation, (never selling, feeding or using a grain of anything not measured and entered in my books," and I can tell by referring to them for 40 years back, every bushel of corn, oats, &c., consumed yearly on the plantation by negroes, horses, cows, hogs, &c., and every dollar expended for plantation and negroes, as well as myself and each member of my family, &c.;) to adopting an ameliorating system, with frequent grass crops; to the use of plaster, marl and lime; and to con- stant attention to plantation manure, of which a great deal is made and used. To these, I repeat it, 1 am indebted for what- ever success I have attained, and I would advise others to pursue substantially the same course, especially in husbanding with great care the resources of the farm, for making manure, and to stick to old Virginia, and make her flourish. I am now about to change my system back to four fields again, believing as I nowj do, from many years' experience, that after, you have improved your land to a certain extent, (if alluvial or flat land,) that the: four field system is the best. It certainly will make more wheat, and nearly as much corn to the acre; and as it affords more landi in each crop, it will make more produce,! and, provided the land improves under it, must be the best system. But the land, must be either good or improved, level or alluvial land, to stand the four field system, or it will not answer ; and you must use good management in manuring and liming, &c., or it will fail : but, with that, I believe it is the best system. The advantage the four field system has over the five is, that it is a more cleansing system, — the hoe-crop (corn) coming round more frequently, keeps the land cleaner, which is all-important in any system. The next advantage in the four field system is, that you turn in a clover ley more frequently, which is highly improving, and at its best stage too for fallowing, which is all-important; and the third is, that you have more land to cultivate, and, provided you have sufficient labor, your returns will be larger. But you cannot support so much stock, and you will have to substitute straw, in some measure for manure, by covering the land with it, which, as it is becomiiig a prevalent opinion that It is the best mode of using straw, is no objection to the system. Coke's, Lord Leicester's, four field system so generally adopted in England, is a very similar one, substituting turnips and barley for corn and wheat, and using more manure than we can affijrd to do. The English sys- tem, on heavily manured land, is turnips, barley, clover, wheat— ^our system is corn, partially manured or limed, or both, wheat, clover and wheat. The corn crop is a more exhausting crop than turnips, but it afibrds a good deal more of offal for manure, and makes up in that way ; and as a bread crop for our?negro population and teams, is inval- uable. But do not understand me as recom- mending the four field system for any but rich or highly improved, and flat or alluvial land. It will not answer for hilly, or rolling, or weak land, fhe^ should have a more ex- tended and ameliorating system, viz: 6, 6 or 7 fields, according to circumstances as mentioned before, so that the more frequent grass crops will intervene, and prevent wash- ing, and restore the fertility exhausted by grain crops, tobacco, grazing, &c. I have been cultivating under the five field system twenty years, after having previously culti- vated twenty years under the four field sys- tem, and I now return to the latter system because my land is sufficiently improved, I think, to stand it, and make more profit un- der it, and perhaps continue, with good man- agement, to improve under it. I think, un- der good management, on good land, where heavy crops of corn and wheat are made, I860.] THE SOUTHERN PLANTER. 577 you may manure an entire field, or fourth part of the land, each year, under the four field system. That is to say, you can cover vith the spare straw and the manure of the plantation one-fourth of it annually; and if 80, it mu." man's tenderest feelings. Activity was the most joyous part of his existence. He could run without being weary, and walk without faint- ing. In his system there was no weakness, giving rise to suffering under exertion ; and in his labor there was no disappointment, to perplex or disturb his mental complacency. The duties assigned to Adam in Paradise were as pleasant to his entire constitution, as the prospect of his luxuriant garden was to his organ of sight, and perception of beauty. It was the cur.'ie — the blight of sin — that changed the entire aspect of human cmploy- jmeiit. Beneath the Irown of an angry (rod the elements of nature were convulsed — the earth became not only barnn, but thorns and thistles sprung upas the indigenous produc- tions of the soil. The original, spontaneous, vegetative powers ol" earth were arrested, so that to man, the offender, it could only yield its reluctant produce, when moistericd with the sweat of his brow, It is, therefore, clear to a demonstration, that the evils of labor are nut in its nature, but in the quantity I necessary to subdue the soil thus blighted — tin the liability to fatigue and exhaustion, in.separable from the shattered constitution of man as fallen — and from the circum- stances, relative and social, in which human toil must be endured. Labor is healthlul and pleasant under proper regulations; all I its embittering elements are the consequences j of sin. * * * * * It is true that many seem to speak and !act as if labor in itself were the curse; but such speak unadvisedly, and act without due I reflection upon the providence of God. The j entire absence of labor could not ameliorate j the condition of the human family, while the I depraved pa.ssions and appetites remain un- restrained. Universal idleness in such cir- 'cumstances would make earth one wide- spread hot-bed of iniijuity, and ev«)ke the ghastly features of even hell itself I AVho are the pests and plagues of society, but such as are idle, whether found in the ranks of wcjdth or tltc rags of poverty ? To re- move huujan labor and leave hun)an deprav- ity, would deterorate rather than improve man's condition. There was mercy, as well as judgment in the decree which enjoined him *' subdue the earth," even though it must be " in the sweat of his brow." With his pre\sent constitution he could not be idle and yet be liappy. Indeed, it is (juestion- ablc whether in any circumstances, a being naturally active could be happy in a sUite of physical inertia. Kven mental activity could not siitisfy the native propulsion of a mate- rial organization invested with life. If, then, this native tendency to action were not re- strained and exhausted by law ful labor, it would be all e . bodied in the production of crime. It has been well remarked by an ennnent writer, (Dr. McCosh,) that, '* if man were not obliged to toil for his bodily suste- 284 THE SOUTHERN PLANTER.

In proportion as man understands his privileges and exercises his capabilities, amidst the profusion of nature, in that proportion will he find its adaptation to his peculiar circumstances, and in so far as he obeys the original mandate, " Subdue the earth," will he find its treasures laid at his feet. " The earth hath God given to the children of men," consequently, it is their province to discern, and dispose of the riches therein deposited, so as to promote human comfort. It is with this view that art is made auxiliary to human power, and has en- abled man to carry his Researches and appro- priation of terrestrial things, beyond the pri- mary limits of manual capability. Nor is this all. The ultimate tendency of inven- tions is to emancipate the human family from the heavier portions of manual labor, and to give the mind more extensive power, so that machinery may take the place of hu- man hands, and one individual be able to accomplish what hundreds could not have effected. — (^Blakeley^s Theology of Inven- tions.^ \_To he continued.'] « • » • » ■ A Valuable Table.

By Samuel W. Johnson, Chemist of the Connecticut State Agricultural Society. 1. What are manures ? Manures are substances which are incor'^ porated with the soil, for the purpose of supplying some deficiency in the latter. However numerous and different may be the materials which assist the growth of plants, judging them by their origin, exter- nal characters and names, chemistry has in late years demonstrated that they all consist of only about a dozen forms of matter, which will be specified below. 2. Hoiu manures act. Manures may act in three distinct ways. I. T'hey may enter the plant as direct nutriment. Carbonic acid, water, ammonia, or nitric acid, sulphuric acid, phosphoric acid, silica, oxyd of iron, chlorine, ffme, magnesia, potash and soda, are the eleniinta of vegetable nutrition — the essential plant- food. In a fertile soil all these materials are accessible to the plant. If one of them be absent, the soil is barren ; if a substance that contains the missing body be applied to the soil, it makes the latter fertile. II. Manures may act partly as solvents^ or absorbents, and thus indirectly supply food to the plant, e. g., lime, gypsum, salts of ammonia, &c. Soils are infertile, not only from the ab- sence or deficiency of some one or more of the above-named forms of plant-food, but also for other reasons. The food of the plant must be soluble in water, so as thus to be transmitted into the plant as rapidly as needed. Soils are often unproductive, be- cause the stores of plant-food they contain are locked up in insoluble forms. Lime, guano, the products of the decay of vegeta- ble matters, often fertilize a field merely by their solvent action on the soil. Gypsum acts as an absorber or fixer of ammonia.. III. Manures improve the physical cha- racter of the soil, — i. e., make it warmer, lighter, or heavier, more or less retentive of moisture, &c. Such are some manures that are often applied in large quantity, as lime, marl and muck. A soil is often barren, not because it has no supplies of nutriment for the plant, neither for the reason that those supplies are insoluble; but because the soil itself is so wet or dry, so tenacious and impenetrable. I860.] THE SOUTHERN PLANTEK. 285 or 80 li^ht ami shiftiriir, that voj^eUition fails to find tlie physical conditions ol* its growth and |ierfecti«)n. Almost all our ordinary fertilizers exer- cise, to a trreater or lesss degiee, all those efl'ects. Thus lime, on a clay soil, may, 1st, Diechinically destroy the coherence and te- nacity of the clay, and jrive it the friability of a loam ; 2d, chemically decompose tUe clay, makinends upon circumstances. Circumstances are ex- ceedingly various and continually changing. The reputation and local value of manures is equally various and changing. In some regions, as in certain districts of Pennsylvania, lime is considered the best manure. In numerous localities, planter (sulphuric acid and lime) is depended upon. In some districts, super-phosphate of lime; in others, Peruvian guano is almost ex.^lu- sively used. Among the substances essential to vegeta- tion, there are some which almost never fail from the soil. Thus, oxyd of iron and silica are present in every soil. Lime and sulphuric acid may often be wanting. Pot- ash and soda are not unfrequently deficient. Available ammonia and phasphoric acid are likewise often liable to exhaustion. Ammonia and phosphoric acid, which po.Hsess the highest commercial value among fertilizers, have been considered by some who.'^e opinions are of weight in the agricul- tural world, to possess also a decidedly great- er agricultural value than other manures. It is as.serted that in the growth of certain crops, and in fact those crops which best remunerate the farmer, these substances are most rapidly exhausted from the soil. Now it is undoubtedly true, that on the soils in certain districts, and in certain courses of cropping, the application of ammoniacal and 286 THE SOUTHERN PLANTER. [May phosphtitic manures produces the most strik- ing results; yet it is by no means proved, or even probable, that on the whole, all soils, and all systems of cropping included, these bodies are of'tener lacking, or oftener and more permanently useful, than some of the other fertilizing substances. 5. What manures are most often and most generaUij useful? While we cannot accord to any simple manure, or to a^y single ingredient of a manure, a universal fertilizing superiority, it is true that some manures are more useful than others, on account of their compound nature. The more ingredients a manure can supply to vegetation, the more useful it is. Stable manure is the universal and best fertilizer, because it contains every thing which can feed the plant. Swamp muck, straw, and vegetable refuse generally, are of similar character. Fertilizers, like lime^ plaster, salt, &c., which contain but a few ingredients, cannot in general be depended upon for continuously maintaining the fer- tility of the soil. 6. Uses of special or partial manures. Special manures, i. e., manures which contain some one or few ingredients, are of use, very rarely, as the farmer's chief reli- ance, but often as adjuncts to stable manure. Several special manures may often be so combined as to make an effectual substitute for stable manure. In hiojh- farming, and in market gardening, and generally where circumstances admit of raising the most ex- hausting crops without fallow, laying down to grass, or. rotation of any sort, special ma- nures are most advantageously employed. In ordinary mixed farming, they are useful in assisting to reclaim or improve poor lands; but in the best practice, they play as yet a very subordinate part, unless peculiar circumstances make them extraordinarily cheap. 7. Comparative commercial value of ma- nures. The commercial value of a manure is measured by its price, and may be quite independent oi its real agricultural value, though it usually depends considerably on its reputed agricultural value. The scarcity of a substance, the cost of preparation and transportation, the demand for it on account of other than agricultural uses — all these considerations of course influence its price. It is commercially worth what the dealer can get for it, so much per bushel or ton. 8. Valuation of manures. — What sub- stances are to he regarded as commercially important iV? costly manures. In any fertilizer which is sold as high or higher than half a cent a pound, there are but three ingredients that deserve to be taken account of in estimating its value." These are ammonia, phosphoric acid, and potash. Every thing else that has a ferti- lizing value may be more cheaply obtained under its proper name. If the farmer needs sulphuric acid he purchases gypsum; if he needs soda, common salt supplies him. Every thing but these three substances may be procured so cheaply, that the far- mer is cheated if he pays ten dollari:^ per ton for a manure, unless it contains or yields one or all of these three substances in con- siderable proportion. 9. Mechanical condition of m,anures. Nothing is so important to the rapid and economical action of a manure as its exist- ing in a finely pulverized or divided state. All costly fertilizers ought to exist chiefly as fine, nearly impalpable powders, and the coarser portions, if any, should be capable of passing through a sieve of say eight or ten holes to the linear inch. The same im- mediate benefits are derived from two bushels of bones rendered impalpably fine by treat- ment with oil-of-vitriol, ten bushels of bone- dust, and one hundred bushels of whole bones. Fineness facilitates distribution, and economizes capital. 10. Chemical condition of manures — State of soluhility^ &c. — Ammonia^ poten- tial and actual — Phosphoric acid, soluble and insoluble. The solubility of a manure is a serious question to be considered in its valuation. We are accustomed to speak of ammonia as existing in two-states, viz : actual and poten- tial, liiy actual ammonia, we mean ready- formed ammonia; by potential ammonia, that which will result by decomposition or decay — '' that which exists in possibility, not in act." Now the former is almost invari- ably soluble with ease in water, and is thus readily and immediately available to plants; while the latter must first become " actual'' by decay, before it can assist in supporting vegetation. In Peruvian guano, we have about half of the ammonia ready formed, and easily soluble in water, the remainder exists in the form of uric acid, which yields ammonia by decay in the soil, but may require weeks or 18G0.] THE SOUTHERN PLANTER. 587 months to complete the change. In leather shavings, or woolen. rags, the ammonia is all potential, and as these bodies decay slowly, they are of less valiio than guano as sources of ammonia. Oilcake, (linseed and cotton- seed,) contains much potential ammonia, and in a form that very speedily yields actual ammonia. A\'e do not know with what precise results the process of the decay of ammonia-yield- ing bodies is accomplished in the soil. Out of the soil such bodies do not give quite all their nitrogen in the form of ammonia : a portion escapes in the uncombined state, and thus becomes unavailable. IMiosphoric acid may occur. in two differ- ent states of solubility J one readily soluble, the other slowly and slightly sohible in water. The former we specify as soluble, the latter as insoluble phosphoric acid. In Peruvian guano we find o.5 per cent, of soluble phosphoric acid, existing there as phosphates of ammonia and potash. The remaining 10 to 12 per cent, is insoluble, being combined with lime and magnesia. In most other manures, genuine superphos- phates excepted, the phosphoric acid is in- soluble. Among those phosphates which are here ranked as insoluble, there exist great dif- ferences in their availability, resulting from their mechanical condition. The ashes of bones, and the porous rock-guano when finely ground, exert immediate effect on crops, while the dense, glassy, or crystal- lized phosphorite of Hurdstown, N. J., and the fossil bones (so-called coprolites of Eng- land,) are almost or quite inert unless sub- jected to treatment with oil-of-vitriol. 11. The rcasonahlc. j^ricc of phosphoric acid, ammovia, and potash. I. Insoluble phospJmrir arid. There arc several substances now in market which, as fertilizers, are valuable exclusively on ac- count of their content of phosphoric acid ; which, moreover, are at present the cheapest sources of this substance that possc^^s the degree of fineness proper to an active ferti- lizer. These substances are the phosphatic guanos, (Coluuibian and American guano,) and the refuse bone-black of .«;ugar refine- ries. From them we can easily calculate the present lowest commercial value of phos- phoric acid. If we divide the price per ton of Columbian guano, 835, by the num- ber of pounds of phosphoric acid in a ton, which, at 40 per cent, amounts to 800 pounds, then we have tlic price of one pound as nearly 4^ cents. Refuse bone black may be liad for 8o0 })er ton ; it usually contains 32 per cent, of phosphoric acid. The same division as above gives us 4^ cents as the cost of phos- phoric acid per pound. In this report I shall adopt the average of these figures, viz: 42 cents, as the reasonable price of insoluble phosphoric acid. Phosphoric acid is much cheaper in crushed bones; but this material is not in a suitable state of division to serve as the ba.sis of a fair estin)ate. II. Sohd/le pJiosphoric arid. This is nearly always the result of a manufacturing process. Professor Way, chemist to the lloyal Agricultural Society of England, estin)ates its worth at 10:> cents per pound. Dr. A'oelcker, of the Koyal Agricultural College of England, and Dr. Stoeckhardt, the distinguisli'.d Saxon Agricultural Chem- ist, reckon it at 12-] cents per pound. They have deduced these prices from that of the best commercial su])erphosphates. In this report the price will also be a.'^sumed at 121 cents. This, I believe, is considerably more than it is really worth, but it is probably the lowest rate at which it can now be pur- chased. III. Actual ammonia. The cheapest commercial source of this body is Peruvian guano. Although it contains several per cents of potential ammonia, yet the latter is so readily converted into actual ammonia, that the whole effect of the manure is pro- |duced in one season, and therefore we may Ijustly consider the whole as of equal value with actual ammonia. Good Peruvian jruano contains : 2 i)cr cent., or lO lb: 12 " 2-10 '' 16 320 per ton of potasli. '• soluble |)liosj)lio. acitl. " iiis^oliible " " niul yields " ammonia. ^ If we add the values of the potash, (see I next page,) and of the phosphoric acid, so- luble and insoluble, and subtract the same from the price of guano we shall arrive at the worth of the ammonia — as follows : 40X'l=$l.nO; fiOX 12i=$7.50; and 210 X .1\=.'f{|0.80; total, .$10.90. $C,5.00—.$ 19-90=$ 15.10 the value of 320 lbs of ammonia. $45.10-1-320 = 14 cents nearly, the value of one pound. 288 THE SOUTHERN PLANTER. [May This price, 14 cents per pound, will be employed in this report. IV. Potential ammonia. The value of this varies so greatly, being, for example, as uric acid in guano, not inferior to actual ammonia, while in woollen rags it is not worth more than one-half as much, that we can fix no uniform price, but must decide what it shall be, in each special case, sepa- rately. V. Potash. The value of potash is diffi- cult to estimate, because it may vary exceed- ingly according to circumstances. Wood ashes are its chief sources 3 these are poor or rich in potash according to the kind of tree that yields them, and the soil on which it has grown. It may vary from five to twenty per cent. Stoeckhardt, who esti- mates the value of ammonia at twenty cents, makes potash worth four cents per pound. The price of potashes can not serve as a guide, for they are never used for agricul- tural purposes. Four cents is certainly high enough for this country, if it is correct for Germany 12. Potash may he usually neglected. Most concentrated manures contain very little or no potash. In guano it rarely ex- ceeds three per cent. Superphosphate of lime can contain none of consequence. Pot- ash cannot be economically added to manu- factured manures, because nearly pure pot- ash, or even the raw material from which it is extracted, viz. : wood-ashes, has a higher commercial value for technical than for agri- cultural purposes. Besides, potat all the different viirietios ubove described, but I have had no choice in the use of it, all the soft phosphatic guanoes below G5 per cent, of bone phosphate, from whatever eourcc they may have been derived, being known by that name in this market. WHITE MEXICAN GUANO. This title was originally given to a very light crmed large quantities have been, and still continue to bo, secretly carted into the city. There ])eing no conceivable honest use Jov which this material can be brought into the city, and it being very similar in color to Pe- ruvian guano, it was reported to be used to adulterate that article, the mixture being put up and sold in old guano bags containing the inspector's mark ! Some months since, the inspector called the attention of the police to the affair, who arrested the parties, carting away this earth in guano bags during the niglit. The arrest was evidently made at an injudicious time, because upon examination the bags were found to contain only the earth. If, however, the parties had been watched un- til they had taken it to their mixing depo^, and completed the crime, tfiey might possiblij bave been properly punisheft. During the late season of active field-work, I endeavored to collect for examination sam- ples of guano, ground bones, and artificial fertilizers, which had been purchased and re- ceived by my farming friends. Finding but few kinds in their possession, I requested that samples might be .forwarded me whenever they shall again purchase. Among others, I got in person a sample of guano from Col. Jno. S. Sellman, of Anne Arundel county, which being sold for Mexican AA, should have contained phosphoric acid equal to 55 per cent, or more, of phosphate of lime, and yet the analysis showed but M} per cent. In this case the Colonel paid for 50 per ct. more phosphate of lime than was implied in the purchase, and if the deficiency had not been discovered, he would have suffered a still greater loss by not applying a proper dose of the phosphate to bis soil. IIow much of this guano was sold, and used by farmers, I have no means of knowing. Samples of other guanoes and fertilizers have recently been received, and are under examination. In using on ammoniated guano we should always mix with it a portion of ground plas- ter, in order to prevent the escape of the am- monia or its carbonate. I may add also that the experience of those who have several times applied Peruvian gnano to the snme field, has jjenerally shown that, after the second or third application, it produces little or uo good result unless other nmnures are also applied. In England the sanjc effects have been observed. This has been attributed to the large pro- portion of ready-made ammonia, whicli tend? to promote a vigcjrous growth of crop, and thus rapidly abstracts the essential constitu- ents of the soil, including its phosphoric acid. It is for this reason that better permanent effect results from mixtures of Peruvian and phosphatic guanoes than the former, when ap- plied alone. The Husband who was to Mind the House Once upon a time there was a man so surly and cross, he never thought his wife- did anything right in the house. So, one evening, in hay-making time, he came home scolding and swearing, showing his teeth and making a dust. " Deer love, don't be angry ; there's a good man," said his goody; ''to-morrow letV change our work. I'll go out with the mow- ers and mow, and you shall mind the house." Yes I the husband thought that ^vould do very well. He was quite willing, he said. So, early next morning his goody took a scythe over her neck, and went out into the hay-field with the mowers, and began to mow; but the man was to mind the house and do the work at home. First of all, he wanted to churn the but- !er ; but when he had churned a while, he got thirsty, and went down to the cellar to tap a barrel of ale. So, just when he had knocked in the bung, and was putting the tap into the cask, he heard overhead the pig come into the kitchen. Then ofli' he ran up the cellar steps with the tap in his hand, a^ fast as he could, to look after the pig, lest it should upset the churn; but when he got up and saw that the pig had already knocked the churn over, and stood there rooting and grunting amongst the cream, which was run- ning all over the floor, he got so wild with rage tliat he quite forgot the ale barrel, and ran at the pig as hard as he could. He caught it just as it ran out of the door, and gave it such a kick that piggy lay for dead on the spot. Then all at once he remembered that he had the tap in his hand ; but when he got down to the cellar, every drop of the ale had run out of the cask. Then he went into the dairy and found enough cream left to fill the churn again, 296 THE SOUTHERN PLANTER. [May and so he began to churn for butter they must have for dinner. When he had churn- ed a bit, he remembered their milking cow was still shut up in the byer (barn), and hadn't had a bit to eat or a drop to drink all the morning, though the sun was high. Then all at once he thought it was too far to take her down to the meadow, so he'd just get her on the house-top — for the house, you must know, was thatched with sods, and a fine crop of grass was growing there. Now, their house lay close up against a steep down, and he thought if he laid a plank across to the thatch at the back he'd easily get the cow up. But still he couldn't leave the churn, for there was his little babe crawling about on the floor, and " if I leave it," he thought, " the child is sure to upset it.'^ So he took the churn on his back, and went out with it; but then he thought he'd better water the cow before he turned her out on the thatch; so he took up a bucket to draw water out of the well, but as he stooped down at the well's brink, all the cream ran out of the churn over his shoulders, and down into the well. Now it was dinner time, and he hadn't even got the butter ; so he thought he'd best boil the porridge, and filled the pot with water and hang it over the fire. When he had done that, he thought the cow might perhaps fall ofi" the house and break her neck. So he got up on the house-top to tie her up. One end of the rope he made fast to the C(^w's neck, and the other he slipped down the chimney and tied round his own leg ; and he had to make haste, for tlie water now began to boil in the pot, and he had still to grind the oatmeal. So he began to grind away ; but whilg he was hard at it, down fell the cow off the house-top, and as she fell, she dragged the man up the chimney by the rope. There he stuck fast ; and as for the cow, she hung 'half way down the wall, swaying between heaven and earth, for she could neither get up nor down. And now the goody had waited seven lengths and seven breadths for her husband to come and call her home to her dinner; but never a call she had. At last, she thought she'd waited long enough, and Went ho i:e. But when she got there and saw the cow hanging in such an ugly place, she ran up and cut the rope with her scythe. But as she did thjs, down came her husband out of the chimney; and so when the old dame came inside the kitchen, there she found him standing on his head in the porridge pot. — Miner s Rural American. For the Southern Planter. Rust and its Effects. Mr. Editor. — I have been much sur- prised, and not a little disappointed, to see such little interest taken by agricultural jourr- als and writers, of a disease which certainly is formidable enough in its effects, to be de- serving of more attention. In vain, have I received my monthlies, and searched them through, with the hope of finding something upon this important subject. Such little in- terest seems to be manifested towards an in- vestigation of the source and effects of " new- fashioned rust," that we might well conclude it to be some harmless disease, impotent in its eftects upon the wheat crop. Such re- flections as these, have induced me to pen this article, which, if it accomplishes nothing else, will, I trust, contribute something to- wards an elucidation of the subject, by di- recting the attention of those more capable than I am, of throwing light upon it. As it is of this " new-fashioned rust," or the rust that first made its appearance two. years ago, that I*design to treat, it might be necessary to describe the " old-fashioned,'^ but as I take it for granted that everybody is acquainted with the difference between them, I hasten on, and will endeavor to be as brief as possible. The disease termed rust, which proves so disastrous in its effects upon the wheat crop, has never, I believe, been traced to any defi- nite cause. Botanists describe several varie- ties, but they fail to enlighten us as to their origin. Indeed, the appearance and depar- ture of these fungi is so mysterious, that the cause of their existence may well evade the scrutiny of the niost searching mind. The disease cannot be traced to an atmospheric or meterologic cause, for its appearance is independent of any such cause. It comes and goes regardless of the peculiar circum- stances accompanying its appearance or de- parture. Many attribute the cause of the disease to the state of weather existing du- ring the time of its ravages. To ascertain then, the causes which originated this species of the parasite, we must resort to more con- clusive testimony than that established upon observing what changes the weather under- goes, during the prevalence of the disease. isua.] THE* SOUTHERN PLANTER 297 This requirea u (le|?reo of scientific rei?earch beyond what has yet been attained, and it would be the veriest presumption to make an attempt, unaided by ^cientitic attainnients, to solve what has baffled the most experi- enced and observant botanists themselves. Without attemptini:, therefore, to account for the disease, which rctjuires and awaits future developments, I pass on to tlic more famjihlc shape assumed by its effects, and will enileavor to prove, by facts based upon comparative deductions, liow these effects may in a measure be avoided. J^efore attempting!: to su;j:u:cst a remedy by which the evil effects of rust may be avoided, the in(juiry naturally arises: llow and in what manner does rust effect wheat ? Why, simply by checking the flow of sap, not de- stroying; the fli>w altogether, but rendering it inconiplcte — thereby preventing the forma- tion and mature development of the grain, which is arrested in its course towards "fill- ing out," partially during the protjrcss of the | disease, and completely after it lias attained! its maximum height. Those who are ac- : quaintod with the manner in whicli the grain forms, and have observed its progress from , time to time throughout the prevalence of the disease, will not perhaps controvert this; solution of its effects in retarding; the forma-' tion of the grain. l In order to establish upon a plausible | basis what I attempt to prove, I submit the! following assertion, viz : The evil effects of! rust are in direct proportion to the growth of straw, that is, the more luxuriant the growth, the more disastrous will be the effects pro- duced by rust. I am led to make this asser- tion from facts carrying with them the strongest convictions of their correctness.. Facts gathered within thesjdiere of my own observation sustain it conclusively. A farm situated upon Nansemond River, capable of; yielding upon an average, twenty busliels ofj wheat to the acre, did not, owing to the of-- fects of ru.st, produce over ten. Hercwlierci the land was rich enough in itself to pro-! duce a rank growth of straw, guano was ap-j plied, thus rendering the crop more suscep-' tible to injury from rust. Likewise upon a; neighboring farm which had two sepcrat^ fields seeded in wheat fall before last, one rich and the other comparatively poor, the same result was observed. The rich land, upon which grew a rank growth of straw, failed to come up to its capacity for yielding grain by about two-thirds, while the poor) land in a different field, and con8e(|uently with a slim growth of straw, sustained uo perceptible injury, but yielded a full crop. I'pon another neighboring farm similar ef- fects were observable. Thirty acres of tluH last mentioned farm were seeded in wheat fall before [ast, and guano applied. The land occupied by these thirty acres is exactly siniilar, both as regards texture of soil and strength, to an hundred acre field seeded in wheat by myself at the same time, but owing to the application of guano upon the thirty acre of the adjoining farm, which augmented the growth of straw, the yield was reduced to one-half the (juantity usually produced, while the hundr<'d acres of my own farm, without the application of any manure or fertilizer whatever, came up, in the yield of grain, almost to the full capacity of the land. AVhy the lnuidred acres failed to come up entirely to its accustomed yield, I attribute to the inequalities of the surface diversify- ing the character of the soil, the low places being much richer than those more elevated, and in these low rich spots the growth was rank and the grain .shrivelled. I could men- tion a multiplicity of cases similar to those already mentioned, which came under my own personal observation, but I refriin, deeming that I have cited enough, and only desire to direct attention towards what I con- ceive to be a subject of great interest and importance to i'armers. 1 will say thougli in passing, in addition to the foregoing, that the comparative failure last harvest of the wheat crop all along James River, the great wheat yjrowing section of the State, sust^iins my position as conclusively as the cases cited. Now, in conclusion, the question arises, granting the effects : what remedy can we apply, to protect ourselves against the ravages of the rust? I will not pretent to answer this question, but in its place, will submit a (juerc or two. Rank growth contains more succulant matter than tlie growth of poor land; may not this preponderence of succu- lant matter, by tending to generate and nur- ture the disease, explain in a measure, why such growth sustains greater injury from tlie rust*/ When rust is anticipated should fer- tile lands, which produce a luxuriant growth of straw, be made to augment such growth by the application of any enriching sub- stance or agent ? l^eaving these queries to the consideration of your many enlightened readers, who are more capable than I am of 298 THE SOUTHERN PLANTER. [May investigating the subject, I draw this article; ah'eady too long, to a close. " Chuckatuck.'^ Stable Management of Horses. The practical suggestions contained in the following article are worthy of .the attention of all who have the care of horses. Give an animal the right feed, :ind take care cf him as ho should be, and he will seldom be unfit for work. How to do these, is told briefly in this article from the Prairie Farmer : It is one thing to know how to use a horse, but is another thing to know how to take care of a horse. A stable horse needs spe- cial care and attention. His feeding must be as regular as the measurement of the hours. When a change of feed is made it must be done with great care — giving a small allowance at first, until the stomach be- comes used to the change. He must be cleaned every day; and when we say cleaned, we mean all that can be conveyed by that word. A good curry-comb, brush and oiled woolen cloth, are the utensils necessary. First take the curry-comb and begin at the top of the neck, back of the ears, working the hands both ways. Proceed in this way till you have gone over the entire body and legs. Then take both comb and brush, and follow the comb with the brush, and after every other stroke, draw the brush across the teeth of the comb to clean it. An experi- enced groom will do this instantaneously. This done, take your cloth and lay the coat, and remove the dust which adheres, to the outside. The face and ears must alsofeel the brush. " Few men know how to clean a horse properly. If the above directions are fol- lowed daily, your horses will enjoy good health generally. Stabled horses must be exercised daily. This is absolutely essential to good health. If the feet of your horse are brittle, and are liable to break and crack, they must be well oiled once a week. A horse thus treated will always be ready to go when wanted, and you will not be ashamed either to ride or drive him. " Another thing quite as important is a a clean and well ventilated stable. We can- not excuse any farmer or horse owner who does not clean his stable twice a day. A stable should be so constructed as to have a wide passage-way or floor in front to feed from. Above the manger a space should be left a foot or two in width clear, and the pr s- sage should be the avenue for the supply of fresh air to the nostrils of the horse. "A horse enjoys a good bed, and it should never be refused him. At night, take your fork and make it up light, and you will feel amply rewarded for the humane treatment you have given your beast." \_NeLV York Observer. New Method of Propagating Plants. At a late meeting of the Royal Society a paper was read " On a New Method of Pro- pagating Plants," by Mr. E. J. Lowe, F. R. A. S. The author states that the experinient of a new method of propagating plants has been so successful that he has thought it de- sirable to communicate his results to the Royal Society, for the guidance of those who are interested in the advance of horticul- ture. It had occurred to him that if a cut- ting of a plant were sealed at the base, so as to exclude the moisture of the soil from as- cending the stem in injurious quantities, the method of striking cuttings of most species of plants would not be so precarious a pro- cess as at present, and accordingly some col- lodion was obtained in order to make the ex- periment. With respect to this new process, he states that immediately upon the cutting being severed from the parent s(em the col- lodion was applied to the wound, and then left a few seconds to dry, after which the cuttings were pitted in the ordinary manner. To test the value of this new process more efl^ctually, duplicates of all the species experi- mented upon were at the same time similarly planted, without the collodion being applied to them. Thus out of 131 cuttings to which collodion was applied 86 took root, and out of the same number to which collodion was not applied only 42 took root. This experi- ment the author considers speaks for itself. Notwithstanding the season being too far advanced for the full benefit of the process to be thoroughly observed, still twice as many cuttings took root treated by the new me- thod as had rooted by the old. The mortal- ity in the open ground was increased by slugs having eaten some of the cuttings above the ground ; those thus damaged were examined after they had been in the ground for a month, and it was found that the col- lodion was quite as sound as when first ap- plied. It would, therefore, appear that the collodion seals the wound of the cutting, and I860.] THE SOUTHERN PLANTER. 2i)0 protects it from the fatal effects of dninp, until roots are prepared to force their way through the covering of ii:un cotton. [^London Fanner s Juurnal. Artificial Flower-Making. Artificial flower-making Is not an insigni- ficant trade. An imjuiry was made into the industrial statistics of Paris in 1S47, which lets us into a little secret in this matter. The total manufacture of cambric flowers in that year was prodigious, amounting in value to more than 400,000/. sterling. We, in Eng- land, onljitook 12,000/. worth of this value ; for we pride ourselves on being able to make our own artificial flowers. The cambric, muslin, gauze, velvet, silk, and other mate- rials were procured from St. Etienne, St. Quentin, and Lyons; the dyes and colours were prepared exptessly for the purpose by manufacturing chemists; the buds, leaves, petals, stamens, pistils, and other component parts, were made in small workshops by per- sons who each attended to only one part of a flower ; while the whole were fitted to- gether in other workshops. Even these workshops are frequently limited to one sin- gle kind of flower each ; so completely is the division of labor carried out. There were about 50 small manufacturerss of petals and stamens, and other component parts, employ- ing about 500 persons ; while there were nearly 600 dealers or vendors, who em- ployed nearly 6000 persons in building up the various integers into whole groups of flowers. Of this immense number of per- sons, about 5000 were women, whose average earnings were estimated at Is. 8d. per day. Siveral of the n anufacturcrs effect sales to the amount of 10,000/. a year each.

Extract from an Address DcUvd'cd hpforc the North Alabama Agri- cultural and Mechanical Association, at Decatur, Ala., Oct. Idth, 1859. BY LT. M. F. MAURY, U. S. N. Ladies and Gentlemen : — We are here to strengthen the hand that guides the plow, and to do homage to t!.e arm that plies the hammer. In the progress of the age, the farmer and the mechanic have become the truest ex- pounders of what science has done and in doing for the world. In every country they are the exponents of its civilization, its cul- ture, and its greatness. What would IMato say could he with his old notions have lived to see this our day, or to hear such a sentiment ? A philosopher frierid of his once Con- structed a piece of machinery according to scientific principles. Plato remonstrated w^ith him upon the grounds, that such a prac- tical application of mathematics tended to degrade science into a low craft, fit only for carpenters, and the like. His remonstrance, we are told, had its effect, and according to ]*lutarch, the science of mechanics was thenceforward considered to be unworthy of a philoso])her. This notion ruled the world for centuries, and kept man groping along in the dark for ages. Indeed, we are hardly yet freed entirely from it ; for there be some men of science, even at the present day, who despise labor, shake the head, and affect to ignore that large and growing class of phi- llosophers that call themselves utilitarian. The true man of science and the brawny armed mechanic arc the complements of each other. They arc brothers; they are as ne- j cessary to material progress, as engine and I boiler are to motion in a steamship ; and if I you ask me which, in my judgment, is most !in)portant, which entitled to most considera- I tion and the highest honors, the mechanic or I tlie man of science, I must beg to answer by ; asking you to tell me which of the two parts , of the steam engine does the builder niake j to the most honor, the piston-rod, or the cyl- inder? If either be wanting there is no progress. j The philosophers of that old school were boilers without engines, for they disdained the mechanic, affecting to regard his occu- pation as degrading, and even immoral. A disciple of one of tho.se schools once inti- mated that men of science might claim the mechanical arch, as one of their achieve- ments. His fellows considered this an in- dignity and an insult. Sen* ca felt himself called upon to resent the imputation, and in his ire exclaimed : " We shall next be told that the first shoemaker was a philosopher!" — a man of science. Why not a shoemaker? The first man of science I ever saw was a shoemaker of Wil- liamson county, Tennessee, — old Mr. NeiJ. He was a mathematician ; he worked out his problems with his awl upon leather, and 300 THE SOUTHERN PLANTER [May would send home liis shoes their soles cov- ered with little x's and ;/'.s. The oxaiiiplo of that luan first awakened iu my breast the young' spirit of emulation ; for my earliest recollections of the feelings of it are con- nected with the aspiration to equal that old shoouiakcr in mathematics. This thing of public opinion is a mon- strous despot, for it wilMiave its own way, and sometimes its own way is wrong. It op- pressed the meclumic and kept him bound for many generations. At last by some ac- cident or chance — for almost all the great inventions and discoveries have been due to chance — he hit upon the art of printing. By that act he sent an agent abroad that was to loose the shackles from his mind and his arms — an agent that was to go forth into the world elevating and lifting man up in the scale of excellence, and moving more masses and greater weights than the lever of Archinicdcs, — plant it where he would, — could pry. When the public saw the first works of this agent in the hands of the old colporteur, the public said it was the "devil with Dr. Faust." But it was no " devil." It was the spirit of a mighty agent, — and see what it has done for the mccnanic, and the mechanic for it! Bacon was the fii'st to detect the true character of this "devil," for he was the first man of science that fraternized w^ith mechanics, and ever since then their pro- gress has been upward and onward. The time is almost within tlie recollection of us all, when the printing press was worked en- tirely by hand; the ink was put on by hand; the paper was laid on by hand ; the forms were rolled under by hand ; and by hand the impression was drawn. I can almost fancy that I see now the merry printer's boy, with his paper cap and apron, smutty face and brawny arms, flourishing away with his two huge balls, drumming merrily some fancied tune, as he inked the types for the next im- pression. In thoFc times 1,000, or 1,500 impressions, was a good day's work for the best pressman; and thus the circulation of a daily paper was limited, even by working day and night and with relays, to some three or four thousand copies. And that same public voice which had so long held the call- ing of the mechanic as ignoble, and kept him down, now began to clamor for more dailies, and a wider circulation, and it was proposed to multiply copies by reduplicating forms. But the demands of the public were for cheaper, as well as for a larger circula- tion. The mechanic understood the call; and bringing to his aid the principles of science, he produced the steam press — an inanimate thing that works like an intelli- gent creature — a very ^^ deviV — sometimes, ibr it makes tyrants tremble. It inks, it rolls, it draws, and throws off more impres-^ sions in a minyte, than in the old way, two or three men could in an hour. Thus the man of science, fraternizing with the mechanic, or both being united in the same person — for the two are by no means antagonistic, or inconsistent with each other — has produced apiece of mechanUm which rules the world. Its messengers go forth morning and evening; at night and at noon they come upon you as noiselessly as the snow-fiake, but they tell upon the popular mind with the voice of thunder, and the power of lightning. The improvements of the age all tend to lift .up and elevate the mechanic. He is bound to be not only almost, but altogether equal to the man of science. When your apprentice boy takes to the books of learned men, do not discourage him in his efforts after knowledge, by talking to him of the mysteries of science. Science has no mysteries ; she is a blab. Nature has her secrets, but the moment science gets at one of .them, it is given to the press, carried by the winds, and steam, and lightning, and scattered over the world, the common prop- erty of mankind. I do not like the idea of considering the mechanic and the man of science necessarily as two distinct beings. You cannot separate them. They are Siamese, and one cannot move in fulfillment of his destiny withaut the other. They are continually calling upon each other for help. They each heed all the calls of man in his perpetual strugle for eon- quests of mind over matter ; and in the strife, sometimes one, and sometimes the other, has the lead. No calling, whether industrial or scientific, can prosper without the aid of the mechanic. He gives agriculture its implements, com- merce its machinery, and science its instru- ments. The astronomer can not move with- out him. If you would see the most ele- gant combination of physical laws and me- chanical skill, conie to Washington and let me show you the great telescope of the Ob- servatory there.

It extended to the planets, they at onee s;iw ; but did it reach to the fixed stars? This piece of handi- work from the shop of the mechanic soon told us : It revealed worlds and systems of worlds among the fixed stars not only movini; in obedience to the laws of gravitation, but shiiiini^ with different lights. Through it, we discovered suns and systems of suns of divers colors — some of fiery red, some bright orange, others emerald green, smalt blue, ash grey, or pearly white, flanii ng through the firuKunent in the brilliancy of their glory. Put the telescope has not, nor has any other instrument yet enabled us to say whether the light of all these suns be com- pounded of the rays of the spectrum, like that shed by our king of day, or whether the diversity created liere by the prismatic cohtrs, be made up Uierc by their orange, blue, green and red suns. Imagine ^'ourselves, my young friends, to be in one of those distant worlds, with an ash-gray sun, that its rays are colorless, sim- ple and uncompounded, affording neither tints to the prism, nor glitter to the dew drop.

The substance of the following pages, and the illustrative cuts, are taken from the author's work on " Scientific and Practical Agriculture." While the greater part is copied literally from the book, some por- tions are so far expanded as to adapt them more entirely to general reading. The two great sources from which plants derive their nourishment, are the atmos- phere and the soil. "VVe can exercise no im- portant control over the condition of the air. Our .Creator has established laws, by which its chemiccil composition is made al- most invariable. The quantity of moisture, too, which it brings and pours out as rain upon our farms, is a matter entirely beyond our influence. i The management of the soil alone has been committed to our hands. Then, Icav- 1 ing the atmosphere in the hands of that j all-wise and beneficent Being, who has, made it an inexhaustible source of food to plants, and of fertility to the soil, let us turn our attention to- those principles and laws which will guide us to a knowledge of the origin and nature of different soils, and to the means by which they can be best cultivated and improved. AGRICULTURAL GEOLOGY. " Geohgy is the history of the mineral masses that compose the earth, and the or- ganic remains which they contain." — Hitch- cock. In its relations to agriculture, geology points us to the origin of soils, and the in- fluence which the rocks have had in deter- mining their different physical and chemi- cal characters. As already stated, they have their origin, generally, in those masses of mineral matter upon which they rest. On the mineral characters of different rocks, then, the mineral character of soils must, to a great extent, depend. Alluvial and drift soils, which are formed of mixed ma- terial derived from various localities, of course form exceptions to this rule. The term " rock," as used by geologists, embraces all the solid mineral matter of the globe ; that is, not simply the firm unyield- ing masses, ordinarily called rocks, but also deposits of clay and other loose material, not necessarily very coherent in character. When we examine the rocks, as they ap- pear at the surface of the earth, we find them under two general forms. ' (1.) Sotne of them exist in layers, which are often parallel, or nearly so, and are found lying one above another. Each one of such layers is called a stratum (plural, strata) ; and masses of rock having this structure are said to be straiified. The ' annexed figure represents a section cut through stratified rocks. The strata are sometimes horizontal, as seen at c, c, in the figure. At other times, and more frequently, they are found in an inclined' position, as at 1, 2, 3, 4. They are then said to have a dip. The angle which the face of the stratum makes with the horizon is the measure of the dip. Very few Stratified rocks are en- tirely horizontal in position ; most of them having a greater or less dip, but varying by every possible angle, between a horizontal and vertical range. | (2.) The other general form under which rocks are found, is that of large irregular masses, having no regular layers; these are termed unstratijied. These unstratified rocks seem,, in most cases, to have been thrust upward through the stratified, by some subterranean force — sometimes form- ing a large part of the central mass or axis of long chains of mountains, as we find strikingly exemplified in many portions of the Blue Ilidge. The granite and trap rocks are the most abundant of this class. The following figure is designed to repre- sent the section of a mountain, by which both stratified and unstratified rocks are IWJ TIJB SOUTUEllN PLANTER. 308 bronjrht to view, in their relative positions j tain.

MINERALS. to have been elevated from their original positio!! by the upward force which elevated the central mass a, a. Stratified rocks generally bear unmistak- able marks of having bien deposited by water, just as we find the same process now going on in the bottoms of seas and lakes. Such being the case, they must have been originally formed ii> a horizontal position, or nearly so. The unstratificd rocks, on the other hand, bear evidence in their iwm and structure, of having been subjected to in- tense heat, and appear to have been often thrown up from beneath the earth's surface in a molten state, Hence they are fre- quently called' "igneous rocks." All the rocks which constitute the outer crust of our earth, bo far as man has been jjble to penetrate, or so far as they have been thrown up within his reach, whether they be stratified or unsfratified, arc com- posed chiefly of a comparatively few min- erals. Before we enter upon a more de- tailed description of the different classes of rocks, it will be necessary to know some- A minei-al is any substance which is not the result of animal or yegetable growth. I All objects which wc can perceive by our 'senses, have been assigned to some one of the three great kingdoms of nature— the animal, vegetable and mineral. Every ob- ject, then, upon the earth, which has not resulted from the action of vita lit ij must be regarded as mineral in its character. Such :a classification would place air and water among minerals; but with these we shall 'have nothing to do at present. It is only the solid mineral substances entering into I the composition of rocks and soils ^ Inch now claim our attention. These are Quartz, Talc, Clay, Feld.spar, Mica, Hornblende and Limestone. Let us examine each of these 'separately. I Quartz. — The purest specimens of ; quartz are found in cryst^iLs, having such .forms a» those exhibited in the annexed figure. The crystals arc all. six-sided prisms, terminated by six-sided pyramids. The different faces of the crystal often vary much in size, giving considyable variety of form, as in those seen at a and h, in the figure. The extreme hardness of thisinin- eral is illustrated by the fact that the sharp angles of its crystals scratch glass very (fii readily. It is the same substance which wc find in the form of flint, sand, carnclian, agate, &c. When particles of sand are cemented into masses, they constitute sand- stone, which is one of the most common and abundant forms of quartz. Chemical relations. We learn from the 304 THE SOUTHERN PLANTER. [May chemist, that quartz (or silica) is an acid ingots chemical relations, being a compound of the metal silicium with oxygen ; its pro- per chemical name%eing silicic acid. At a very high temperature, this mineral com- •bines readily with strong bases, such as soda, potassa and lime, forming a class of chemical salts, called " silicates/' Natural silicates are very numerous, as we shall pres- ently see; and they enter very largely into the composition of the rocky masses of the earth. Talc is a silicate of magnesia. It is sometimes found in layers as thin as paper, having a green, or greenish-white colour. The surface, when rubbed with the fingers, feels greasy. When a layer of it is bent, it does not regain its former condition, like mica, a mineral- of the same form. Soap- stone and French chalk are- compact forms of talc, and are frequently found in exten- sive masses. Soft clay slate is frequeritly called soapstone, but is really a mineral of very different composition, and will be described under clay, in the next para- graph. Clay. — This is a silicate of alumina, and is found abundantly all over the world. In a pure and pulverized form, it consists of extremely fine grains, which, when wet, form a cohesive mass. Among its purest natural forms are pipe-clay and porcelain- clay. It enters very largely into the com- position of rocks, from which it is liberated in large quantities by the action of rains and frosts, as will hereafter be described. Slate is a compact form of clay, of greater or less purity. AVhen sufficiently firm and of proper structure, it is used fi)r tiles, writing-slates, &c. When soft and brittle it is called "shale." Mingled with sand, pebbles and organic matter, clay consti- tutes the body of the great majority of soils. When perfectly pure, it is white, but we generally find it coloured" in a variety of shades from light-yellow to dark-brown — the colouring matter being oxides of iron and manganese. To the farmer^ it possesses the highest interest. Although not a fertilizer, in the sense of affording nourishment di- rectly to the plant, it serves an important purpose in giving compactness to the soil, and in retaining moisture, ammonia, and other fertilizing substances. Feldspar is a double silicate of potassa and alumina. Soda is frequently found in it, taking the place of potassa in whole or in part, and modifying to some extent the structure as well as the composition of the mineral. Feldspar is sometimes massive, and sometimes of a regular crystalline struc- ture. When it occurs in regular crystals, they have the form represented in outline by the figure here given, which is an ob- lique rhombic prism. The crystals are of- ten quite flat, and have their ends so modi- fied, as to appear of different and less reg- ular shape than the above figure w^ould indicate. The surfaces of the crystals, es- pecially the broader faces, have a brilliant, lustre like that of glass, with something of a pearly appearance. The most common colours, of this mineral are white, gray, green a fid flesh colours. All these varieties may be found amongst the rocks taken from the Blue Ridge tunnel on the Central Railroad. Feldspar is not quite so hard as quartz, but is sufficiently so to scratch glass. When exposed to the direct influence of the weather, this mineral is gradually de- composed. The silicate of potassa is re- moved by the combined action of the air and rains, while the silicate of alumina re- mains as fine particles of clay. If the feldspar is pure, the resulting clay is white — passing under the mame of " kaolin," is extensively used in the manufacture of por- celain ware. In the decomposition of feldspar, we have a striking illustration of the part which the carbonic acid of the air performs, in connection with other agencies, in produ- cing changes of character in rocks. The silicate of potassa is decomposed by the strong affinity between carbonic acid and potassa, a carbonate instead of a silicate be- ing produced. This carbonate of potassa is readily dissolved and carried off by rains, while the silical^ of alumina is left, as a minutely divided clay. But there is always enough of potassa (and soda, if it be pres- ent) retained to meet the wants of the crops that may grow upon the resulting I860.] THK SOUTHERN PLANTEi^. 305 soil, if other minerals, such* as quartz and mica, are coiitaiiielue Uidge, as well as in nearly all regions where the jirimary stratified rocks make their appearance. When com- pact in structure, it forms a strong and val- uable building stone, and is often inij)roper- ly called granite. The soils resulting from its disintegration are similar to those from real granite, but difl'erent s))ccimens cif both granite and gneiss vary widely in the pro- portions in which their constituent minerals occur, and of course must give a cor- responding variation in the soils they pro- duce. Hornblende is more complex than either of the simple minerals above describ- ed. It is composed of silica, eondjined with magnesia, lime, alumina and oxide of iron. The different- varieties, however, vary son)ewhat in composition and ajipearance. Those containing a large per cent of iron are of a very dark colour, while those con- taining but little iron are of very light shades. Its crystals are prisms, soujctimes short and stout, and at other tinjcs lc»ng and slender. In fine fibres, easily saparated, and very flexible, it forms a.*-bestus, a ma- terial used for making incombu.-itible cloth. Hornblende exerts an important influence upon soils which have resulted from the rocks containing it — especially the daiker varieties — affording an abundance of both linir and o.nWr of inm, two of the most im- portant e^einents of fertilit}-. Trap is a heavy, hard, unstratified rock, not un frequently called " green.stone." It consists of an intimate mixture of feldspar and hornblende, and occurs sometimes in beds of* vast extent, as njay be seen in many of the higher an the range or bearing of their upturned edges. We infer, that volcanic action, on an extensive scale, has been the agency in producing these changes; first, because no other known cau.se is sufficient; secondly, because the masses which have been thrust upward amongst the stratified rocks, and against which they rest, as in the second of the preceding figures, bear all the marks of having been in a stiite of fusion, and are similar, !n man}' respects, to those about volcanoes, which are known to be of igneous origin. 6. The elevating forces seem to have acted at successive periods of time, with long intervals of repose. The evidence of this is seen in the fact, that those strata lying nearest to the line in which the eleva- tion has taken place, seem to have been, at first, elevated through a short distance, and to have remained in this position, with but little dip, until a second set of strata were deposited horizontally, with their edges rest- ing against those first formed. Then, by a second action of the elevating force, both of these sets of strata have been again up- heaved on one side, so as to increase the dip of the first, and give to the second a dip which is somewhat less. In many localities several of such periods appear to have followed one another. 4. More intimately connected with the subject of the geological origin of soils, is the fact, that the mineral matter accumu- lated, and built up into stratified rocks over the expanse of ocean -bottom, varied widely in quality at difl"ercnt periods of time. During one period limestones formed the predomincnt material deposited. Again, slates, formed from indurated clay, were accumulated; then, perhaps, a stratum of sindstonc, or conglomerate. These do not follow each other in any definite order, but such is their position, that wherever any one of them comes to the surface, it gives char- acter to the soil overlaying it. 5. The stratified rocks, however, have another point of diff'erence, which is much more definite than that of- mineral compo- sition; it is found in the character of their Ibssil remains. Our globe appears to have pa.sscd through various stages of condition and climate, suited to difi'erent ordei-s of animal and vegetable organisms. This we learn by examining the only record we have of their history, the rocks above which they have lived, and in which they have found a vast burying-ground. As we advance from the rocks which lie lowest in the sciies, to those which form the upper strata, we find in our researches, first a class which seem to have been deposited in regular layers 308 THE SOUTHERN PLANTER.

Ascending still higher, we discover the varieties of fishes multiplying, and the frog and tortoise tribe making their appearance. Again we come to vast accumulations of vegetable deposits, Avhich nature has laid up as fuel lor the use of busy man, that he may drive himself and his business forward with increasing speed for ages yet to come. Then we find still higher up, the records of those times, when great reptiles and sea.monsters held their sway, and when birds began to take possession of their peculiar element. Above these we find the entombed mam- malia, the hippopotamus, the ox, the deer; with fowls, and fishes, and reptiles, appoach- ing more and more nearly to the character of those we daily see around us. Bur,, in all our search, we have looked in vain for man, or for any traces of his art. It is not till we have passed through all the stratified rocks, that we find our own species leaving his mark amongst the physical records of a world, which has at a comparatively recent period been made his habitation, and placed beneath his control. On the basis of these wide differences amongst the rocks and their fossils, geolo- gists have marked out definite "groups," to which they apply the term *'• formations." These formations having been produced at successive times, indicate what are called " geological periods." Of these we shall have something to say, in the order of their relative ages. Frogs. An enterprising citizen of New Jersey has prepared ponds for the purpose of raising frogs for the table. They readily command the price of one dollar per hundred at wholesale. Frogs are becom- ing the common article of food. number, upon his article on vegetable phys- iology, which preceded mine in the order of publication in your paper. As the professor seems willing to " sit at my feet, or any one prepared to give him instruction," I shall not despair of yet making him a convert; but I would advise him not to be determined beforehand, to be " a little slow of appre- hension," and "if not always ready to adopt his (my) theories," at least weigh well the facts that may be brought forward in their support. As to authorities, while I give them their place, I prefer facts, for it is only by observing facts as they present themselves to the inquiring mind, that the laws of na- ture can become known. And first : I must correct one misappre- hension into which the professor has fallen, — as I cannot help thinking — with his eyes open. At least, without much stretch of the imagination, I think a more rational conclu- sion might have been come to. I admitted that the sap brought up from the roots ma- terial for growth, and that another portion was collected from the air in the form of car- bonic acid gas, by the leaves, and after ad- mitting this as true, the writer then goes on to say : " Having nov7 a portion of the ma- terial necessary for the nourishment of the growing plant, brought up from the roots to the leaves, and another portion collected by the leaves from the air, we are left to infer, (as far as Mr., Taylor tells us anything to the contrary,) that it all remains in the leaves, exce[)t the water evaporated through their pores." It is true I did not say in so many words, that the carbonic acid imbibed by the leaves was distributed through the sap of the plant, as I admit to be the case, inasmuch as the sap near the leaves would contain a very small portion of matter from the roots, the principal part being deposited below. I did, however, assert the fact, of the acid mixing with the sap, objecting to the term " dissolved." I stated the fact of the great affinity of water for that gas, from the known fact, that it could not be mixed with a portion of water without every I860.] THE SOUTHERN PLANTER 809 portion of water in contact bcconiini^ ini- pre^rjatcd with it. And I fiirtlier stated, tliat '* plants are precisely in that position to make theni the niediuni between the earth and the air," in the transmission of el( etricity betworn them, " and more par- ticularly tliritUL;h the water of the sap where it meets the <;as." I now leave the })r()fes- 1 Bor to judge how far his " reliable autliori- ties differ from Mr. Taylor," merely saying that a majority of authorities is no evidence 1 of being in the right. Authorities differ,, liowever, even by tiie profess^or's own show- ] ing. Who shall decide when doctors dis- agree ? Science must come to facts, for facts alone can substantiate it. The fact of the ab- sorption of gas by the leaves is freely ad mitted ; but' I still think, that if all the matters for growth have to be brought up to the leaves, and then descend after being vitalized, in the descending sap, there is every reason to suppose that these materials would be deposited more rapidly near the leaves than they are The supposition that, on the same principle, " the niineral matters would be deposited nearer the root," is not appropriate. It is si law of vegetable life, that plants have the power of separating the materials for growth, and depositing in each place its appropriate kind of matter. Tluis the wheat plant deposits
