Comparatively little hemp is prepared in this manner in America. Process retting by means of weak solutions of chemicals or oils in hot water is practiced to a limited extent. The hurds from these processes may contain traces of the chemicals or oils and also soluble gums in greater degree than those of the dew-retted or water-retted hemp. PROPORTION OF HURDS TO FIBER AND YIELD PER ACRE. The yield of hemp fiber varies from 400 to 2,500 pounds per acre, averaging 1,000 pounds under favorable conditions. The weight of. Fig. 1. -Hemp-breaking machine. The stalks are fed sidewise in a continuous layer 2 to 3 inches thick, turning out about 4,000 pounds of clean fiber per day and five times as much hurds. hurds is about five times that of the fiber, or somewhat greater from hemp grown on peaty soils. A yield of 2^- tons of hurds per acre may be taken as a fair average. HURDS AVAILABLE FROM MACHINE-BROKEN HEMP. Hemp hurds are available only from hemp which is broken by machines, when the hurds may bo collected in quantity in one place (figs. 1 and 2). Most of the hemp in Kentucky is still broken by hand brakes. These small brakes are moved from shock to shock, so that the hurds are scattered all over the field in small piles of less than 50 pounds each, and it is the common practice to sot fire to them as soon as the brake is moved. It would be difficult to coUoct them at a cost which would permit iholr use for pap(U' stock. Where machine brak(!S are used, the h(unp stalks are brought to tho machine as grain is brought to a thrashing machine, and tho hurds.
