The sample from the Rocky Ford Station was unusu¬ 
ally leafy, while that from the College Farm was taken 
from the cock and was average hay. 
The following are samples from the Farm Department, 
all of which were prepared by Prof. W. W. Cooke:

Numbers 1 and 2 represented individual plants cut May 
28th, just before the field was mown. Number 3 is hay from 
the same field, cut on the 28th, but was damaged by rain.

The samples of hay, Nos. 1 and 2, were cut from the 
same roots as Nos. 1 and 2 of the first cutting.

The average percentage of protein found in our sam¬ 
ples for the first cutting, including all the different stages of 
development, is 14.85, but excluding samples cut May 5th, 
lt: is r 3-98 ; for the second cutting, 14.43 i and for the third, 
(this is based on too small a number of samples) 13.05. The 
farm samples show the same relative values for the respect¬ 
ive cuttings, though the samples are fewer in number. For 
the first cutting, 14.92 per cent., for the second, 13.99 per 
cent., and for the third, 13.47 per cent. Perhaps analysis No. 
3 first cutting—of the farm samples, ought not be included 
in the averages, because it was not gathered into the mow 
for fifteen days after it was cut, during which time it had 
been exposed to several rains. 
As this is the only sample of alfalfa hay damaged by 
rains that we have analyzed, we will make mention of it in 
this place. The average of the analyses made of samples 
taken from the same field and cut the same day, but dried 
in an air bath, shows the composition of the prime water- 
free hay to be:—
