Report op the Assistant Chemist of the 
Wisconsin, and to Prof. W. H. Jordan, of the Maine Agricultural 
Experiment Station. These samples, with those from this Station, 
show marked differences, which can only be fully accounted for after 
trials extending through a number of years. 
The following description accompanied the sample received from 
Maine : 
No. XV. Crop of 1885, sampled from mow of pure timothy hay. 
No. XXIII. Timothy from crop of 1886, cut when about ten days 
past full bloom, sampled from large lot. This and XV were grown on 
rather heavy clay loam. 
We do not know the history of the sample from Wisconsin, except 
that it was cut while in bloom. 
Those from this Station were grown upon clay soil which had been 
laid down to grass for several years. The samples for both years were 
cut from the same plat and at the same stage of development, i. e., in 
full bloom.

The timothy from Maine, crop of 1885, was much richer in albumi- 
noids than the crop of 1886, showing considerable variation in the hays 
for the two years. In comparing the three timothies of 1886, that from 
the New York Station is very deficient in albuminoid content, while 
that from Wisconsin is exceptionally high, but the proportion of fiber 
is also very high. Certain it is that meteorological influences modify 
largely the composition of the grasses, for the timothy grown at the 
Station for two years, 1886 and 1887, under like conditions, so far as 
soil and treatment were concerned, present such variations as can in 
no other way be accounted for. 
The digestibility of the albuminoids of the several hays was 
determined, and their coefficients are given below :
