COTTON.

No product of the soil is more useful than this. To this country alone we give the highest value to Indian corn. But, in usefulness to the whole world, corn must yield the palm to cotton. It employs more hands and capital in manufacturing, and enters more largely into the clothing of mankind, than any other article. The history of cotton and the cotton-gin, and of the manufacture of cotton goods, is exceedingly interesting. The eminence of Great Britain as the first commercial nation of the world is due, in no small degree, to her cotton manufactures. And the influence of this great staple American product upon all the interests of this country, social and political, civil and religious, is universally felt and acknowledged. The cotton-fields of the South, at certain stages of growth, and especially when in bloom, present scenes of beauty unsurpassed by any other growing crop. It does not come within our design in this work to give a very extended view of cotton culture. This business in the United States is confined principally to a particular class of men, known as planters. They cultivate it on a large scale, having the control of large means. Such men seek knowledge of those of their own class, and would hardly condescend to listen to an essay on their peculiar business, written by a Northern man, not experienced in planting. And yet an article, not covering more than ten pages of this volume, might be written, condensing in a clear manner all that is established in this branch of American industry, as found in the publications of the South. Such an article, well written, by a man who would be regarded good authority, would be of vast pecuniary value to the South. Whoever carefully reads Southern agricultural papers, and "Turner's Cotton-Planter's Manual," will see a great conflict of opinions on the subject, and yet a presentation of many facts, that one thoroughly conversant with soil culture in general would see to be true and important. The embodiment of these facts and principles in a brief, plain article that would be received and practised, would add value to the annual cotton crop, that would be counted by millions. What better service can some Southern gentleman do for his own chosen and favorite region than to write such an article? We give the following brief view of the whole subject, not presuming to teach cotton-planters what they are supposed to understand much better than we do, but to throw out some thoughts that may be suggestive of improvements that others may mature and carry out, and to lead young men, just commencing the business of planting, to look about and see if they may not make some improvements upon what they behold around them. This will not fail of being interesting to Northern men, most of whom know nothing of the cotton-plant, or the modes of its cultivation. It is interesting, too, that some of the most essential points are in perfect accordance with the great principles of soil culture throughout the world.

There are three species of cotton: tree-cotton, shrub-cotton, and herbaceous cotton. The tree-cotton is cultivated to considerable extent in northern Africa, and produces a fair staple of cotton for commerce; being produced on trees from ten to twenty-five feet high, it is not so easily gathered. The shrub-cotton is cultivated in various parts of the world, particularly in Asia and South America. Growing in the form of small bushes, it is convenient, and the staple is fair. But these are both inferior to the herbaceous cotton. This is an herb growing annually, like corn, a number of feet in height, more or less according to soil and season, and producing the best known cotton. Under these species there are many varieties: we need speak only of the varieties of herbaceous cotton. Writers vary in their estimates of varieties; some say there are eight, and others put them as high as one hundred. This is a question of no practical moment. The sea-island cotton, called also "long staple" on account of its very long silky fibres, is the finest cotton known. Its name arose from the fact of its production in greatest perfection on the low, sandy islands near the coasts of some of the Southern states. It does well on low land near the seashore. The saltness and humidity of such locations seem peculiarly favorable to its greatest perfection. It yields about half as much as the "short staple" called Mexican and Petit gulf cotton, and known in commerce as upland cotton. But the sea-island, or long staple, sells for three or four times as much per pound, and, hence, is most profitable to the planter, in all regions where it will flourish well. The Mexican is very productive on most soils, and is easily gathered and prepared for market. There are quite a number of other varieties; as, banana, Vick's hundred-seed, Pitt's prolific, multibolus, mammoth, sugar-loaf, &c., &c. The sugar-loaf is highly commended, as are some of the others named. They have had quite a run among seed-sellers. Most of these varieties are the improved Mexican. It is well to get seed frequently from a distance; but any extravagant prices are unwise. Improvement of cotton-seed is an important part of its most profitable culture. While much said about it by interested parties is doubtless mere humbug, yet there is great importance to be attached to improvement of seed. This is true of all agricultural products, and no less so of cotton than of others. Two things only are essential to constant improvement in cotton-seed—selection and care. Select from the best quality, producing the largest yield, and maturing early; pick it before much rain has fallen on it after ripening; dry it thoroughly before ginning, and dry it very thoroughly after it is clear of the fibre, before putting it in bulk. Cotton-seed, without extra care in drying, has moisture enough to make it heat in bulk, by which its germinating power is greatly impaired. It is this, and the effects of fall rains, that causes seed to trouble planters so seriously by not coming up: this makes it difficult to obtain good even stands, and causes much loss by diminished crops. Care in these respects would add many pounds to the acre in most cotton-fields of the land.

Preparing the Soil for Planting.—On all land not having a porous subsoil, plow very deep; it gives opportunity for the long tap-root of the plant to penetrate deep, and guard against excessive drought. The usual custom is to lay the ground into beds, elevated a little in the middle, and a depression between them, in which excessive moisture may run off; also to increase the action of the sun and air. The surface of the soil to be planted should be made very fine and smooth. This is true of everything planted—it should be in finely-pulverized soil; it comes up more readily and evenly. Soil left in coarse lumps or particles gives the air too much action on the germinating seeds and young plants, and retards and stints their growth. Deep plowing guards alike against too much or too little moisture. Too much water has room to sink away from the surface and allow it to dry speedily. It also forms a sort of reservoir to hold water for use in a drought. The seed should be planted in as straight a line as possible, from three and a half to five and a half feet apart one way, and from fourteen to twenty-five inches the other, according to the quality of the land, and the growth of the variety planted. Rich lands will not bear the plants so close as the poor. Many are great losers by not securing plants enough on the ground. Straight lines greatly facilitate culture, as it can mostly be done with the plow or cultivator. Turning land over deep, just before planting, is the best known remedy for the cut-worm; it is said to put them back until the plants grow beyond their reach. The best planters generally cover with a piece of plank drawn over the furrow in which the seed is dropped. It would be far better to roll it, as some few planters do; the effect on the early vegetation of the seed and rapid growth of the young plant would be very great, on the general principles given on "Rolling." The object of cultivation is to keep down the grass, which is the great enemy of the cotton. Plowing the last thing before planting aids this, by giving the cotton quite as early a start as the weeds or grass. Cultivate early, and the grass will be easily covered and killed. Always plant when it will come up speedily and grow rapidly; this is better than very early planting, and certainly much better than very late. Thin out to one in a place, as early as the plants are out of danger of dying. Gathering should commence as soon as bolls enough are in right condition to allow a hand to gather forty pounds per day. It is better and cheaper than to risk the injury from rains after the crop is ripe.

Manures.—Perhaps this is, at the present time, the greatest question for cotton-planters. The application of all the most approved principles and agents of fertilization would do more for the interests of the cotton crop than anything else. Cotton-plantations are sometimes said to run down so as to render it necessary to abandon portions of the land, and select new. Instead of this, land may not only be kept up with proper manuring, but made to yield larger crops from year to year. The following analysis of the ash of the cotton-plant will indicate the wants of the soil in which it grows:—

This analysis shows that the soil for cotton needs much lime, bones or bone-dust, and wood-ashes, besides the ordinary barn-yard and compost manures. All the preparations and applications of manures specified in this work, under the head of "Manures," are applicable to cotton. The usual recommendations of rotation in crops is, perhaps, more important in cotton culture than anywhere else. Judicious fallowing, on principles adapted to a Southern climate, is another great means of keeping up and improving the land. This is also the only effectual means of guarding against the numerous enemies and diseases of the cotton-plant. The health of the plants is secured, and they are made to outstrip their enemies only by the fertility and fine tilth of the soil in which they grow. This is confirmed on every hand by the correspondence of the most intelligent planters of the South. Let cotton-growers go into a thorough system of fertilization of their soils, and attend personally to the improvement of their cotton-seed, by selection, as recommended above, and the result will be an addition of one eighth, or one fourth, to the products of cotton in the United States, without adding another acre to the area under cultivation. When this comes to be understood, men of small means will cultivate a little cotton by their own individual labor, as the poorer men do corn and other agricultural products, and thus improve their condition. The above suggestions are the conclusions to which we come, from a thorough examination of what has been published to the world on this subject. We recommend the careful perusal of "The Cotton-Planter's Manual," by Turner (published by Saxton and Co., New York), and increased attention to the subject, by the intelligent, educated, and practical men with whom the cotton-growing regions abound.
