local sources. It is to be pointed out that artificial dehydration in the Mid- west takes place on forage crops that are generally low in moisture 65 percent may be given as the highest in standard practice.

Such chopped materials are a watery-viscous mass that defy mechanical breakup actions that would fully expose each small plant part to the hot air currents within a dehy- drator. Hence, the drying process is very slow and often thin leaf sections are burned to a char before the mass is dehydrated. New Prospectus A forage crop is normally selected and grown on the basis of a farmer's ability to make hay or silage using natural methods of curing and processing. A new prospectus in growing a crop for cattle production may be centered on crop yields in terms of feed qualities, the period when available, the associated farm work requirements, and the degree of response to mechanical dewatering and other physical operations leading up to direct feeding, silage making, and arti- ficial dehydration. Table 3 gives data on the response of different crop materials to mechanical dewatering. This information was obtained with three presses loaned by Dan B. Vincent, Inc., Tampa, Florida, and data collected both at the Durrance Ranch, Brighton and Belle Glade, Florida. Percent Moisture
