gested in the animal system, while the liquid manure contains 

 the waste products of the digested food. 



Ordinary farm yard manure, from cows, oxen, and growing 

 cattle, has the following average composition. The composition 

 of horse manure, sheep manure, and hog manure, is also given : 



In order that we may be able to know the actual amount of 

 plant food applied to an acre, in any given case, I will give the 

 best available figures showing the weight of a cord of manure. 



Manure from neat cattle and sheep will weigh not far 

 from 8,000 pounds, or four tons per cord ; horse manure, 6,000 

 pounds, or three tons ; while hog manure, as usually found, will 

 probably weigli more than either of those given. As manure is 

 ordinarily drawn in a cart holding forty bushels it will require 

 three loads, without treading to make a cord. The number of 

 cords and tons may thus be estimated with considerable accu- 

 racy. In the following table I have figured the actual plant food 

 per ton, per cord, and per load of one-third cord :
