DRIED PRESSED POTATO. 
Two investigators in the United States Department of Agricul- 
ture, William Stuart, of the Bureau of Plant Industry, and H. C. 
Gore, of the Bureau of Chemistry, have been studying the potato 
situation in the United States for the purpose of determining a 
suitable way to dispose of surplus potatoes. The dried pressed 
potato used in the feeding experiments was manufactured at the 
Government Experimental Farm, Arlington, Va. The following 
analysis of the feed shows that it is rich in carbohydrates, mostly 
starch, and poor in fat, protein, and ash ingredients. 
Chemical analysis of dried pressed potato used in experimental work.
