The cotton fiber—a highly magnified view, showing the twist

It is a curious ruling of fate which makes the spinning of cotton fiber possible. There are many other short vegetable fibers, but cotton is the only one which can profitably be spun into thread. Hemp and flax, its chief vegetable competitors, are both long fibered. The individuality of the cotton fiber lies in its shape. Viewed through the microscope, the fiber is seen to be, not a hollow cylinder, but rather a flattened cylinder, shaped in cross-section something like the figure eight. But the chief and valuable characteristic is that the flattened cylinder is not straight, but twisted. It is this twist which gives its peculiar and overwhelming importance to cotton, for without this apparently fortuitous characteristic, the spinning of cotton, if possible at all, would 7 result in a much weaker and less durable thread. The twist makes the threads "kink" together when they are spun, and it is this kink which makes for strength and durability.

Though the cotton plant seems to be native to South America, Southern Asia, Africa, and the West Indies, its cultivation, was largely confined at first to India, and later to India and the British West Indies. At the beginning of the eighteenth century, the West Indies, because of their especial fitness for growing the longer staples were supplying about seventy per cent. of the food of the Lancashire spindles. The United States having made unsuccessful attempts to produce cotton in the early days of the colonies, first became an important producing country toward the end of the eighteenth century. American Upland cotton, by reason of its comparatively short staple, and the unevenness of the fibers, as well as the difficulty of detaching it from the seed, was decidedly inferior to some other accessible species. The Southern planters who grew it, moreover, found it next to impossible to gin it properly, the primitive roller gin of the time being unsuited to the task, and the work of pulling off the fibers by hand being both tedious and expensive. In 1792, the amount exported from the United States was equivalent to only 275 bales.

Eli Whitney, the schoolmaster inventor of the cotton gin

The next year, 1793, is the most important in the history of cotton growing in the United States. In the autumn of 1792, Eli Whitney, a young Massachusetts man who had just been graduated from Yale College, sailed from New York to South Carolina where he intended to teach school. On shipboard he met the widow of Nathaniel Greene, the Revolutionary general. Mrs. Greene invited the youth to begin his residence in the South on her plantation at Mulberry Grove, Georgia. Here one evening, some officers, late of General Greene’s command, were discussing the great wealth which might come to the South were there a suitable machine for removing stubborn Upland fiber from its green seed. The story goes that while the discussion was at its height, Mrs. Greene said:

"Gentlemen, apply to my young friend, Mr. Whitney. He can make anything."

Whitney commenced work on the problem. A room was set aside as his workshop, and it was not long before he had produced the beginnings of the gin. He fixed wire teeth in a board, and found that by pulling the fibers through with his fingers he could leave the tenacious seed behind. He carried this basic idea further by putting the teeth on a cylinder and by providing a rotating brush to clean the fiber from the teeth.

The changes which followed immediately 8 upon the introduction of the cotton gin were tremendous in scope and almost innumerable. There was a time, before cotton became a staple, when the South led New England in manufacturing. That time passed almost immediately. Iron works and coal mines were abandoned, and men turned their energies from the culture of corn, rice, and indigo largely to the raising of the cotton.
