A cotton-seed Huller.

--We went yesterday to the Muscogee Iron Works, to see the operations of a mill for hulling cotton seed, the invention of Mr. Isaac Mitchell, of this city. It was working very successfully, separating the kernel from the lint as completely as the gin separates the lint and seed. The machine is a very simple one and easy operation. The seeds are thrown into a hopper and husked by grinding plates, passing out into a cylindrical revolving selves, about four feet long and inclined downward from the mill. By the revolutions of this cylinder the kernel is made to drop through into a trough under neath it, while the hull and lint, unable to pass through the sieve, are worked out at the lower end of the cylinder.

The kernel, thus separated, is very easily reduced to oil of superior quality, for burning purposes and hardly distinguishable in taste or smell from good olive oil. It always commands at least $1 per gallon, and now sells much higher. The chief difficulty in the way of making oil from cotton seed is that of separating the kernel from the hull by a cheap process, and this, we think, Mr. Mitchell has accomplished.

This is a subject of immense advantage to the South, as the success of this enterprise will add greatly to the value of the cotton crop, besides making the South independent in its supply of oil. We learn that 100 lbs. of cotton seed will yield about 59 lbs. of kernel, and that this amount of kernel will yield fully two gallons of oil.

Cotton seed oil has for some time been manufactured in New Orleans, but we understand that the hulling is there done by machinery so expensive as to forbid its use on plantations. Mr. Mitchell's invention is cheap and simple. We learn that he has applied for a patent.--Columbus Enquirer.
