The most striking thing in regard to the sheep manure 



is the extremely low percentage of phosphoric acid. It will 



be noted that we obtained, in valuable fertilizing materials, 



about one and one-half cents' worth per sheep per day. 



The determinations of the amount of _, .

manure produced by swme were made m 



the same general way as the sheep, i.e., by keeping the swine 



continuously upon tight galvanized iron pans and weighing 



and analyzing the bedding separately. Two determinations 



were made with two lots of swine fed on different rations; 



one lot, known as the carbonaceous lot, was fed nothing but 



corn meal; the other lot, known as the nitrogenous lot, was 



fed a ration of two parts corn meal and one part flesh meal. 



It will be noted that the excrement differed very materially 



both in amount and quality, as is shown by the following 



analysis:
