 cow nearly dry. lasting from December 1 to 12. The food consisted 

 exclusively of cotton seed hulls, about 20 pounds per day. The «'xcreta 

 were collected and analyzed the last 4 days. The data obtained during 

 the trial aie talmlated. The coenicieiits found were, ash 27.14, cellulose 

 27.11, fat -SO.Ol. i>n»tein 24.«ll. and nitrogen tree extract 40..5 per cent. 

 "More nitrogen and phos])horic acid were extreted tlian fed." This is 

 believed to be due to loss of tlesh and to indicate that "cotton seed 

 hulls did not constitute a maintenance latioii for the animal." The 

 digestibility and composition of the cotton-seed hulls are compared 

 with those ob.served elsewhere for wheat straw.
