different proportions to find the amounts best eaten. The experiment was 
normal throughout. Sheep A and B had no salt in their mangers the last eight 
days of the test. Sheep C and D had salt every day. 
No. 2 wheat middlings with fine rowen. The rowen was the same in this 
experiment as in No. 30 and No, 32. The experiment began March 258, 1896, 
and continued twelve days. The feces were collected for the five days from 
March 20, at 6:30 A. M., to March 25, at 6:30 A.M. Each animal, sheep A, 
ra B, C and D, was fed daily 4oo grams of middlings and 400 grams of rowen.

DIGESTION EXPERIMENT NO. 34. 

Oat fodder, fed green. This and the following experiments with green fod- 
ders were made particularly to test the digestibility of fodders used in feeding 
iE tests with milch cows. ‘The general plan was to feed three days ,without 
i sampling, then four days taking sample 1, then four days taking sample 2, 
then one day without sampling. This had at times to be modified to meet 
various conditions, particularly the weather, This experiment began Julya 
1896, and continued twelve days. The feces were collected for the five days 
a from July 14, at 8:30 A. M., to July 1g, at 8:30 A.M. Each animal, sheep A 
and B, was fed daily 2,740 grams of the fodder. The first sample was taken 
July 10. The oats were full size, seeds about half grown, stems large and 
slightly woody. The second sample was taken July 15. The oats were full 
grown and beginning to seed, some of the stems turning yellow and quite 
woody. Neither sheep ate full rations, and B left so much uneaten that he was 
dropped from the experiment. The experiment was repeated later with sheep 
C and D as No. 37. In this latter test less fodder was fed per day. 
DIGESTION EXPERIMENT NO. 35. 
Oat and pea fodder, fed green. The experiment began July 7, 1896, and 
continued twelve days. The feces were collected for the five days from July 
14, at 8:30 A. M., to July Ig, at 8:30 A. M. Each animal, sheep C and D, was 
fed daily 2,740 grams of the fodder. ‘Two samples were taken, but one was 
lost. In the second sample, taken July 15, the oat stems were turning yellow 
and quite woody. The seed was about half grown. The peas were quite 
badly lodged and many stems blackened. There were few blossoms and many 
pods, some with seeds full grown. Neither sheep ate the full ration, and on 
account of the large amount of uneaten residue C was dropped from the experi- 
ment. This test was repeated later with sheep A and B as experiment No, 36, 
_in which less fodder was fed per day. 
DIGESTION EXPERIMENT NO. 36. 
Oat and pea fodder, fed green. The experiment began July 20, 1896, and 
continued twelve days. The feces were collected for the five days from July 27, 
at 7 A. M., to August I, at 7 A.M. Each animal, sheep A and B, was fed daily 
2,340 grams of the fodder. At the time the first sample was taken, July 23, 
the oats were in the early milk stage. The peas were fairly succulent. Stems 
lodged and lower parts turned brown. Many pods and seeds developed. The 
second sample was lost. Both sheep ate full rations.
