MANURES. 1 1 1 



Yet the difference is not so great as would be sup- 

 posed. The quality of manure depends very much 

 more upon the food from which it is made than upon 

 the animal by which it is made. Linseed meal or 

 cotton-seed meal, which contains much nitrogen, and 

 is rich in phosphates, makes manure worth infinitely 

 more than that from straw and turnips. Whether 

 these articles of food have passed through an ox or 

 a hog, makes very little difference ; though, as ex- 

 plained below, it does make some difference. 



STABLE MANURE. 



By stable manure we mean, usually, that of the 

 horse, and that of horned cattle. The case described 

 in Chapter II. (of this Section) was one where the 

 animal was not increasing in any of its parts, but 

 returned in the form of manure, and otherwise, the 

 equivalent of everything eaten. This case is one of 

 the most simple kind, and is subject to many modifi- 

 cations. 



The growing animal is increasing in size, and as 

 he derives his increase from his food, he does not re- 

 turn in the form of manure so much as he eats. If 

 his bones are growing, he is taking from his food 

 phosphate of lime and nitrogenous matter ; conse- 

 quently, the manure will be poorer in these ingre- 

 dients. The same may be said of the formation of 

 the muscles, in relation to nitrogen. 



The fattening animal, if full grown, makes manure 

 which is as good as that from animals that are not
