The following is from other specimens of fresh farm 

 yard manures, analyzed by Messrs. Allen and Greenhill. 



By knowing the composition of the added manures and 

 the subtracted crops, the farmer can keep an intelligent 

 account of debt and credit with his fields. If he could make 

 an exact estimate of the portion of .,the soil that might be- 

 come soluble in the course of the growing season, (available 

 for the present crop), and carry into this account also, the 

 sum of the elements exhausted by drainage and evaporation, 

 as well as those added from the atmosphere, rains and dews, 

 and appropriated to vegetation or permanently fixed in the 

 soil, he would then be able, at all times to know, precisely 

 what additional ingredients (special manures) would be 

 necessary, and in what proportions, to secure the largest 

 amount of any required crop.

Poudrette is the name given to the human feces after 

 being mixed with charcoal dust or charred peat. By these 

 it is disinfected of its effluvia, and when dried, it becomes a
