MANURES. 201 



According to this analysis, a ton of manure, (2,000 lbs.,) con- 

 tains, in addition to 1,323 lbs. of water and 515 lbs of insoluble 

 organic matter, (woody fiber, etc.,) the following quantities of the 

 more valuable manuring ingredients : — 



Ammonia 1 5.60 lbs. 



Soluble phosphoric acid 3.64 " 



Insoluble " " 3.56 " 



PoUsh 13-44 " 



Total , 36.24 " 



As stable manure in towns is usually sold by the cord, I have 

 caused a well-trodden cart-load of good livery-stable manure, (in 

 which hogs had been constantly working, but which contains the 

 usual proportion of straw,) to be carefully weighed, and I find a 

 cord of this manure to weigh 7,080 lbs. 



Taking 7,000 lbs., (or 3 1-2 tons,) as the standard weight of 

 one cord (128 cubic feet) of manure, we find it to contain, 

 according to the foregoing analysis, about the following quanti- 

 ties : — 



Water 4,632 lbs. 



Insoluble organic matter, (woody fiber, &c.) I>8o3 "

Total of the more valuable parts 127 « 



This seems, at first sight, to be an exceedingly small propor- 

 tion of the more valuable fertilizing ingredients ; yet, if we esti- 

 mate them at their market price, we shall find that they alone are 

 sufficient to give great value to the manure. 



In Judd's "Agricultural Annual " for 1868, (p. 40,) we find the 

 following : — 



" From a comparison of the cheapest available sources of the 

 " most valuable ingredients in manures, we give the following as 

 " not far from fair prices by which to estimate fertilizers (it is
