THE CATTLE MANURES. 
We will now turn our attention to the cow or cattle manures col¬ 
lected during the same winter as the sheep manures, but not presenting 
so continuous a series. To enable a better comparison, we give an aver¬ 
age analysis which is obtained from about fifty analyses as given by 
Storer in his “Agriculture.” Many of the analyses included in this aver¬ 
age are of fresh manures, but this does not affect the results for they 
were not much higher in moisture than the old manures. This aver¬ 
age represents manures as they are met with in moist climates.
