the college herd. Each of the animals had calved within four 
months previous to the beginning of the tests. The following 
is a brief description of the animals: 7 
No. r.—A grade Jersey; weight about 700 pounds; about 4% 
years old; calved March, 1895; not with calf at starting of test. 
No. 2.—A Jersey and Guernsey cross; weight about 800 
pounds; 8 years old; calved in March, 1895; not with calf at 
starting of test. 
No..3.—A pure Jersey; weight about 750 pounds; 8 or 9 
years old; calved. March, 1895; due to calve February or 
March, 1896. 
No. 5.—Grade Jersey; weight about 700 pounds; 8 or 9 years 
old; calved April, 1895; not with calf at starting of test. 
Vo. 6.—Grade Jersey; weight about 800 pounds; 8 years 
old; calved June 14, 1895; not with calf at starting of test. 
No. 7.—Grade Jersey; weight about 800 pounds; 6 or 7 
years old; calved May, 1895; not with calf at starting of test. 
OBJECT AND PLAN OF EXPERIMENTS. 
The object of the experiments was to study the relative effects 
of leguminous and cereal fodders on quantity of milk, and on 
total quantity of fats and solids in the milk. ‘The plan of the ex- 
periment was to take two groups of cows as nearly alike in total 
yield of milk and of butter-fat as could be readily found, and 
to feed one group mainly on leguminous fodders, plants belong- 
ing to the clover family, and the other group on cereal fodders, 
or plants belonging to the grass family. At the beginning of 
the experiment both groups were fed on a similar ration, and 
the yields of milk and fat compared. ‘The fodder used for this 
preliminary test was oats and peas. Then cows 1, 2 and 3 were 
continued on the same class of fodders as in the preliminary 
test, while cows 5, 6 and 7 were given cereal fodders, beginning 
with oat fodder. 
The green fodders were in all cases hauled to the barn and 
fed.in the mangers, a two-days’ supply usually being weighed 
out at one time. A small grain ration was fed once each day 
in addition to the green fodders. This was the same for each of 
the animals during all of the time of’the tests. The different 
fodders were fed in nearly every instance fora period of two 
weeks, and the test included the last nine days of this period. 
Five days of preliminary feeding preceded each test.
