that claim to have solved the problem—supposed to be past finding out—of picking cotton by machinery. Large fields flank the buildings, and on these are tested the various kinds of cotton seed, fed by the various kinds of fertilizers, each put in fair competition with the others. One of the most important special inventions at the exposition will be the Clement attachment—a contrivance for spinning the cotton as it comes from the gin. The invention is simply the marriage of the gin to the spindle. These are joined by two large cards that take the fibre from the gin, straighten it out, and pass it directly to the spinning boards, where it is made into the best of yarns. The announcement of this invention two years ago created very great excitement. If it proved a success, the whole system of cotton manufacture was changed. If the cotton could be spun directly from the gin, all the expense of baling would be eliminated, and four or five expensive steps in the process of cotton from field to cloth would be rendered unnecessary. Better than all, the South argued, the Clement attachment brought the heaviest part of manufacturing to the cotton field, from which it could never be divorced. By the simple joining of the spindles to the gin, the cotton, worth only eight or nine cents as baled lint, in which shape it had been shipped North, became worth sixteen to eighteen cents as yarns. The home value of the crop was thus to be doubled, and by such process as New England could never capture. Several of the attachments were put to work, and were visited by thousands. They produced an excellent quality of yarns, and made a clear profit of two cents per pound on the cotton treated. The investment required was small, and it was held that $5000 would certainly bring a net annual profit of $2200. Many of these little mills are still running, and profitably; but difficulties between the owner and his agents, and a general suspicion raised by his declining to put the machine on its merits before certain agricultural associations, prevented its general adoption. That this attachment, or some machine of similar character for spinning the cotton into yarns near the field where it is grown, will be generally adopted through the South in the near future, I have not a particle of doubt; that the exposition with its particular exhibits on this point will hasten the day, there is every reason to hope. There are many yarn mills already scattered through the South, but none of them promise the results that will be achieved when the spindles are wedded to the gin, and the same motive power drives both, carrying the cotton without delay or compression from seed to thread.
