THE SOIL OF THE FARM. 



(producing their whole effect almost at once) or by pur- 

 chases of food for live stock and the artificial enrichment 

 of their manure, will always be one of the most interest- 

 ing for the farmer. The latter plan, which now forms 

 part of all good farm management, is theoretically much 

 the more economical, and practically much the more en- 

 during. 



Considering the operations of auimal nutrition and 

 growth as a mere chemical process, the manure excreted 

 has a value which, calculated according to the data sup- 

 plied by the manure market, is a very large proportion 

 of the original market price of the food. Sir John B. 

 Lawes has prepared the following table, giving the value 

 which ought to be realized from the manure derived 

 from different kinds of food;
