Flesh. The muscular flesh of animals is 

 rarely used as a manure, because, it is of greater 

 vahie for feeding hogs ; but, such as is not 

 used for the latter purpose can be dried after 

 previous boiling, and then powdered, in which 

 state, it is an excellent manure. In its norma! 

 state, it contains more than the half of its 

 weight of water ; dried in the air, it still re- 

 tains S to 9 per cent. Perfectly dried, it has 

 14.25 per cent, of nitrogen. As sold in com- 

 merce, (^5 per 225 lbs.) it contains 13.04 per 

 cent, of nitrogen. 



Blood. The blood of slaughtered animal- 

 is less suitable, for the nutrition of hogs, thai, 

 muscular flesh ; it sometimes even creates 

 disease, and should therefore be preferred for 

 the fertilization of the soil. For this purpose., 

 it must be coagulated by ebullition, and then 

 dried in a furnace. In a liquid state, it is ani 

 improper manure, for its decomposition is so 

 rapid as to dissipate the resultant products^ 

 and thus depreciate its fertilizing effects. Ta 

 obviate this, however, it is only necessary tov 

 dilute the blood largely with water and there- 

 with irrigate the fields ; or it can be soaked 

 into calcined humus, and then spread upon
