The average coefficients obtained are well within the range 
found by other experimenters, with the exception of the coeffi¬ 
cient of digestion for the fat or ether extract, which is far below 
the coefficient given for fat in timothy hay cut before or in bloom, 
and even lower than the minimum given for fat, 34.6, in timothy 
hay cut past bloom. The digestion coefficient of crude fibre is 
lower than the minimum given for timothy hay cut before or in 
bloom, but above the maximum for timothy cut after bloom. The 
digestion coefficient for the fat is markedly low. The same fact 
is observable in the results obtained for the digestion coefficient 
of fat in corn fodder. The native hay gives us a higher coeffi¬ 
cient for the digestibility of the fat or ether extract than is given 
for blue joint, a meadow grass common in the East; but as al¬ 
ready noted, the Eastern blue joint and the Western blue stem are 
different grasses, and their digestion coefficients may not be the 
same, in fact, are probably not the same, and my only justifica¬ 
tion in comparing them is the very general one that they each 
constitute a meadow hay. 
We will have to take up the question of the digestion coeffi¬ 
cient of fat in a subsequent paragraph, after we have set forth the 
results obtained with alfalfa hay. 
The timothy hay used was purchased in the Denver market, 
it had been grown in the mountains, had been cut in early bloom 
and well cured. It was as good a sample as we could hope to pro¬ 
cure either in the market or by growing it on the Station farm.
