Bulletin 93. 
The hay fed was not the same as in the former experiment. 
The sheep were younger and of a different breed, and the condi¬ 
tions of air, sunlight and general attention to the comfort of the 
animal were more favorable than in the former experiment. All 
of these facts should be taken into consideration in comparing the 
results. As both samples of hay were obtained in the Denver 
market, I cannot be more than morally certain that they were of 
about the same age, bnt I really entertain no doubt on this point. 
If we may judge by the amount of orts left, the hay used in the 
first experiment was more palatable to the sheep than that used 
in the second. The total amount of orts left by the three sheep 
in the first experiment was 60 grams, while they aggregated 
4493.0 grams in the second. 
The individual taste of one of the sheep was very marked in 
the second series, as it seemingly ate none of the timothy heads, 
all of which seemed pretty mature. 
I will restate the results obtained in the first experiment that 
the differences may be the more easily observed: 
The Digestion Co-efficients of Timothy Hay, First Series. 
Dry Matter. Ash. Fat. Protein. Fibre. Extract. 
Sheep No. 3. 56.83 34.62 26.01 57.51 56-33 62.72 
Sheep No. 4. 59.52 32.94 35.85 58.70 57.56 64.53

Jordan and Hall give the digestion coefficients for timothy 
hay before or in bloom as follows:

The coefficient 
found 
for the 
fat 
or ether extract 
in 
the second series 
seems 
to 
be 
an exception, 
be- 
ing much higher than the maximum given by Jordan 
and Hall for this constituent of the hays, but the coeffi¬ 
cients found for the three sheep are in much closer agreement 
than we usually find to be the case in this work. With this ex¬ 
ception we find in both series a very marked tendency toward 
lower coefficients than other experimenters have found—a result 
which was specifically mentioned in connection with the coeffi¬ 
cients found for corn fodder.
