Food for o f clear excrement of the following percentage composition 

 PUnt> were obtained: 



Nitrogen i.oo per cent. 



Phosphoric acid 08 " 



Potash 1.21 "

The other details of the experiment were as follows : 



3 Sheep for Average per 



33 2-3 Days. Sheep per Day. 



Weight of sheep 426 142 



Food consumed 536 5.3 



Water drunk 765 7.5 



Total excrement 723 7.2 



Nitrogen, pounds 7.21 .071 



Phosphoric acid, pounds .60 .005 



Potash, pounds 8.74 .086 



Nitrogen, value $1.08 $0.01 



Phosphoric acid, value .04 .0004 



Potash .39 .004 



Total value $1-51 $0.015 



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 swine were 

 made in the same general way as the sheep, i.e., 

 by keeping the swine continuously upon tight gal- 

 vanized 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: 



Nitrogenous, Carbonaceous, Average, 



Per Cent Per Cent Per Cent 



Nitrogen 9 .74 .83 



Phosphoric acid 06 .01 .04 



Potash 64 .58 .61
