teeth of the saws, in turning over, continually cut downwards in front of the cylinder, which is placed close to a long hopper, extending the whole length of the cylinder, and so close to it that the seeds of the cotton cannot pass between them. This cylinder revolves, with almost inconceivable rapidity, and great caution is necessary in working with the gin, not to touch the saws. One end of the cylinder and hopper being slightly elevated, the seeds as they are stripped of the wool, are gradually but certainly moved toward the lower end, where they drop down into a heap, after being as perfectly divested of the cotton as they could be by the most careful picking with the fingers.
The rapid evolutions of the cylinder are procured by the aid of cogs and wheels, similar to those used in small grist mills.
It is necessary to be very careful in working about a cotton-gin; more especially in removing the seeds from before the saws; for if they do but touch the hand the injury is very great. I knew a black man who had all the sinews of the inner part of his right hand torn out—some of them measuring more than a foot in length—and the flesh of his palm cut into tatters, by carelessly putting his hand too near the saws, when they were in motion, for the idle purpose of feeling the strength of the current of air created by the motions of the cylinder. A good gin will clean several thousand pounds of cotton, in the seed, in a day. To work the gin two horses are necessary; though one is often compelled to perform the labour.
