lot, was so damaged by exposure as to be worthless. The 
-cows refused to eat the damaged hay. 
The digestibility of the albuminoids was determined by 
the pepsin method, and the information thereby obtained 
gerves to place each fodder more nearly in the order in which 
it belongs as is shown by the following.

From the experiments of Dr. Jenkins! it would seem that 
it is possible we may by pepsin digestion find a means ot 
determining the relative,availability of the nitrogen of dif- 
ferent nitrogenous fertilizers. A few of the results obtained 
by Dr. Jenkins are repeated here from his report.

It certainly seems from the above that we have here a 
means of grading fertilizers according to the availability of 
their nitrogen. Such a classification would add much 
value to an analysis. 
COMPOSITION OF DIFFERENT CUTTINGS OF GRASS. 
In making fodder analyses my attention has frequently 
been attracted by the larger per cent of albuminoids in the 
second and subsequent cuttings of grass over that of the 
first crop, and afew of the analyses have been brought 
together here showing this difference. 
Meliotus alba, (Bokhara clover).
