pounds each. About the same amount is annually imported into the United States from Egypt.
The upland cotton of the United States is mostly derived from Gossypium herbaceum. In this country the varieties of this species have white flowers, which turn red the second day after opening. The fibre of this series is shorter, but the plant can be cultivated over a greater extent of territory than the others. The seed of the upland varieties is usually of a greenish color and has a closely adherent gray fuzz in addition to the longer lint, making the process of ginning more difficult. There are doubtless many hybrids between these series, as may be seen in the character of some upland cottons. In 1896 descriptions were published in the United States Department of Agriculture, Office of Experiment Stations, Bulletin 33, of more than 130 varieties of cotton in cultivation in the United States at that time, together with about an equal number of so-called varieties which were only old ones renamed. Most of these varieties were upland cottons, and they varied widely in their production and character of lint. Gossypium arboreum is a small tree rather common about the temples of India and China, but it is said never to be cultivated as a regular crop. The trees are rather short-lived, and they yield a fine, silky fibre an inch or more in length. This is called Nurma or Deo cotton and is little used except by the priestly class. It is probable that its value has been overrated. It will not mature in the United States. The origin of the cottons supposed to be derived from Gossypium Peruvianum is somewhat in doubt. They are South American, as their name would indicate, and their smooth black seeds adhere in a reniform mass, hence the name ‘kidney cotton,’ which is usually applied to them. Their fibre is strong, rather coarse and woolly, one and one-half inches or less in length, and from its great resemblance to wool is frequently used in combination with that staple. About 15,000 bales are annually imported into the United States, and it is claimed that most of it is used by woolen manufacturers to mix in making underwear, hosiery, etc., much of the material being sold as all-woolen goods.
In commercial usage, to fibres under 0.98 inch or 25 millimeters in length there has been given the name ‘short staple’; ‘medium’ means from 0.098 to 1.17 inches (25 to 30 millimeters), and ‘long’ 1.18 to 1.57 inches (30 to 40 millimeters); ‘extra,’ including those which are 1.58 inches (40 millimeters) or more. The extra and the long in the United States seem to come from Sea Island cotton or some of its hybrids; the short and medium from Gossypium hirsutum or Gossypium herbaceum.
The commercial classification of cotton in New York is as follows: The ‘full grades’ are fair, middling fair, good middling, middling, low middling, good ordinary, and ordinary. Half grades are designated by the prefix ‘strict,’ quarter goods by prefixes ‘barely,’ meaning the point above half grade and the next full grade above, and ‘fully,’ meaning the mean point between the half grade and the next full grade below, Liverpool high grades are lower, and low grades higher than New York.
Cultivation. The plant requires for its best development a peculiar soil and climate. While the method of cultivation is about the same in the various countries where it is grown, that in the United States is the most perfect. Although the plant is not really an annual, it is treated as such in its cultivation. The land is prepared in winter, the time of beginning varying with the locality. After thorough plowing, and after all frost has gone, the ground is bedded into rows from three to four feet wide, according to situation and the quality of the soil; the seed is sown along the centre of these beds, either in a straight furrow made with a small plow or opener, or in holes twelve to eighteen inches apart. Where artificial fertilizers or cottonseed-meal are drilled in this method of preparation is indispensable. The usual date to begin preparing land is from January 15 in southern Texas to March 5 in South Carolina. Sowing usually commences March 10 to April 15 and continues to May 15; but late spring frosts may delay it longer. The young shoots, which appear in from ten to fifteen days, are weeded and thinned when they have attained a height of two to six inches, say, when the third or first true leaf appears. The average date of bloom is June 5. As a general rule, cotton is a dry-weather plant, heavy rainfall interfering with both the culture and the stand, although an extremely dry spring interferes with the growth. For plowing it is best to have just enough rain to make the soil moist and spongy. When young, the crop flourishes best with warm steamy weather, with an occasional shower until blooming. An excess of rain produces weeds and wood; severe drought stunts the plant, matures it too early, and causes a small, light-stapled crop. Early frost causes the plant to turn brown; cold nights cause many of the plants to die. Lands in hilly or upland districts require more moisture than those lying in the plains and river bottoms. Overflowing often causes injury on bottom and flat prairie lands, but replanting or recuperation often redeems the most hopeless cases. Where, however, overflowing causes ‘sanding,’ the land is rendered utterly useless for cotton culture that year. The experiment stations in the Southern States have aided in introducing improved methods of cultivating, fertilizing, and handling the crop. Rotation of crops and green manuring have been shown to be of great advantage. From the date of bloom, warm, dry weather is needful, until picking time, which usually commences from July 10 in southern Texas up to September 10 in Tennessee, and continues until frost puts a stop to further growth. During the harvest all available hands are called into full employment. The cotton is gathered into baskets or bags hung from the shoulders of the pickers, and when the crop has been secured it is spread out, dried, and then the fibre separated from the seeds. For long-staple or Sea Island cotton in South Carolina the usual date to begin preparing land is February 1; planting begins April 1 and ends May 1; picking is from August 25 to December 10.

Cotton Diseases. There are a number of well-characterized diseases of the cotton-plant, some of which are due to disturbances in the nutrition of the plant, others are caused by fungous attacks, while still others are attributed to the presence of minute worms, called nematodes, in the roots. Attention to the requirements of the plants will correct the first class of diseases. For the fungous troubles but little in the way of prevention
