persons who keep horses for road purposes, liverymen and 
others, will not use alfalfa hay. On the other hand, feeders 
of cattle and sheep use alfalfa principally, if not exclusively, 
in this section. I do not know how this matter stands rela- 
tive to pea-vine hay, but the pea-vine silage has been fed 
with very satisfactory results. 
It would seem that the low esteem in which alfalfa is 
held as feed for horses, is mostly due to its action upon the 
kidneys and bowels of the animal and also to the fact that 
the loss in feeding horses alfalfa hay is very large, due to 
their not eating the leaves readily, and lastly, because the 
alfalfa is sometimes dusty. It may be that this is in part a 
practical recognition of the fact that the nutritive ratio of 
the whole hay is rather a narrower one than is desirable. 
He this as it may, an average alfalfa hay has a much larger 
percentage of proteids than the upland hay, also less crude 
fiber, and the proteids in the alfalfa have a higher co-effi- 
cient of digestion. The same is in a measure true of clover 
hay, but the upland hay is preferred for feeding animals at 
work. 
The composition of the upland hay was as follows : 
Per cent. 
IVIoisture T047 
Ash 7.886 
Ether extract 2.219 
Proteids 6-kV 
Crude fiber 40.372 
Nitrogen-free extract 40-35^ 
Total 100.000 
The co-efficient of digestion for the proteids found by 
artificial digestion was 45.77, about equal to that given for 
the proteids in late cut timothy. I gave on a preceding 
page an analysis of hay made from Stipa viridula, in com- 
parison with an analysis of a mixed hay. In that analysis 
the proteids are given as 8.gi per cent. We see that it is 
richer also in this constituent than our native hays, which 
are in great demand at all times. Not only is the amount 
of the proteids larger in the Stipa, but their co-efficient of 
<ligestibility is also higher, being 64.71. It would have been 
interesting to have studied the Stipa hay still further to see 
if we could solve the question why this grass is not eaten, 
but we were compelled to drop the comparative study at 
this point, and all that we are justified in stating is that, in 
spite of the fact that cattle do not eat it, it has, according to
