NVe charge the containing vessel with water to within three or four ,inches from thc/cop, and having arranged the roll e to run at about two hundred revolutions a minute give lnotionI thereto. A large quantity of water is raised by the roll, but the curved plate h intercepts the water and returns it between the directing-plateiand cover g to the tail end, and Ahence largely increases the ow. I n au engine of the size shown, with a charge of two hundred and twenty-four pounds of husk and fiber material, the roll running about two hundred revolutions per minute, the whole charge of water and materialwould be driven roundthe engine from twoP to three tunes a minute. It will be obvious the tearing or I opening action of the beater accelerates the separation of the ber from the husks.

`Motion can be given tothe water 1u any convenient manner, but we prefer to employ this engine. We consider it important ,to maintain the current at a speed of from forty to sixty feet a minute.l

Although the action of the current of .water is the feature whereby the separation is e'ectively accomplished, 'we, in practice, as means,

With husk and ber material from Smyrna and East India seed, we rst boil it in water, preferably with a few pounds of soda; then subject it to the action of a current of wat-er to separate the inner husks. We next treat the material, which now consists of the ber and outer husks, to 'the action of caustic soda, heat, and moisture in the proportions above set forth for material from Americanand African seeds.

Having now described the nature of our said invention and the manner of carrying the same -into practice, we would have it disof water, for the purpose of separating the ber from the husks, substantially as herein set forth.
