The total loss upon successive extraction with 95 per 
cent, alcohol, cold water, and then hot water, was 37.8 per 
cent. The amount extracted from alfalfa hay was, in round 
numbers, 28 per cent. I did not in this case determine the 
amount of nitrogen removed by the extractions. 
The crude fiber in this case contained 77.88 per cent, 
cellulose, and 22.12 per cent, of lignones; practically identi- 
cal with the composition of the crude fiber prepared from 
alfalfa. 
The nitrogen-free extract, however, differs both quan- 
titatively and qualitatively from that of the alfalfa. To 
what extent this difference is due to the difference in the 
development of the plants at the time the samples were cut, 
would be interesting to know. The absence of the sugars 
in the alfalfa sample and their presence in the clover may 
be wholly attributable to this. Alfalfa is our principal 
honey plant and yet this sample which was just coming into 
bloom yields only traces of the sugars. That they are sub- 
quently present cannot be doubted ; but whether they are 
ever present in sufficient quantity to constitute more than 
a fraction of one per cent, of the hay is a question. 
PEA-VINE HAY. 
As the quantity of pea-vine hay made in this state ag- 
gregates a large amount, I shall, at the risk of digressing 
too much, give a brief presentation of it in comparison with 
the other hays, particularly in comparison with alfalfa and 
clover hays. The variety of pease here dealt with, is what 
is designated the Mexican pea. It is a strong grower and 
quite prolific. I am indebted to Mr. James A. Kelley, of 
Monte Vista, Colorado, for one of the samples of hay and 
to Mr. R. E. Trimble for the other. Both samples are from 
the San Luis valley, where the pea-vine hay, to a certain 
extent, takes the place of alfalfa and clover hay of this por- 
tion of the state. 
I am informed by Mr. Kelley that experiments in feed- 
ing pea-vine hay to horses, steers, and sheep have given 
very satisfactory results, especially so with sheep. Mr. Kel- 
ley’s statements of its effects upon horses indicate that they 
are similar to those of alfalfa, but are much milder and he 
makes no mention of its producing any cough or the 
heave.>. This hay even when cut, after many of the pease 
have ripened, is an acceptable fodder to cattle and one on 
which they do well. 
I'he sample furnished by Mr. Kelle>' was in perfect 
condition ; the plants were almost at full bloom at the time
