160 MANURE FROM GROWING AND WORKING ANIMALS.

 little being rejected that can be made to aid in increas

a. In the milch cow, we have a still stronger in 

 stance. Here* every thing available goes to the secre 

 tion of milk; -even the body becomes thin and ema 

 ciated by this constant drain : the consequence is, that 

 the manure is poor and watery, containing only the 

 refuse of the food, with the small waste of the body. 

 These two kinds of manure, from the milch cow, and 

 from the rapidly growing animal, may be considered 

 poorest of all. 



Manure from full grown working animals, is usually 

 of excellent quality. If they work steadily, their food 

 must be good in order to keep them in condition: of 

 the carbon contained in it, so much as necessary, and 

 this of course the largest part, owing to the amount of 

 exercise that they take, is used in breathing ; and for 

 this reason the manure is as it were concentrated, and 

 is rich in nitrogen, in phosphates, and the saline sub 

 stances of the food generally. All that is above the 

 daily supply to keep up the body, and the bones, comes 

 into the manure. 



In fattening an animal, the aim is simply to increase 

 the bulk of its flesh and fat; the bones have attained 

 their full size already. By far the greater part of the 

 fatty matter in the rick food given, is in this case 

 appropriated to the increase of the body, beside a 

 large portion of the nitrogenous substances also; but 

 a goodly quantity of both still goes into the manure, 

 and it is rich in inorganic materials. 



These two last varieties of manure, from full gro\vn, 

 and from fattening animals, should be preserved with 

 much care. It is proper for the farmer to remember, 

 that in feeding his stock well, he is not only increas 

 ing their weight, but is also benefiting his land for 

 the future, by the rich and powerful manures whiclj
