Lixperiments at the Massachusetts (fatch) Experiment Sta- 
tion.**—'The experiments, two in number, made under the 
direction of Dr. J. B. Lindsey, were conducted during the 
autumn and winter of 1895+96. Six cows were used. ‘They 
were divided into two lots. The division was such as to make 
the productive capacities of the two lots as nearly alike as pos- 
sible. During the first half of each experiment, three of the cows 
were fed the narrow ration, while the other three were receiving 
the wide ration. In the second half of the experiment, the order 
was reversed. In the first experiment the two periods were 
twenty-six days each, and at least seven days were allowed 
after the animals were placed upon the full ration, before the 
actual test was begun. In experiment 2 the periods were 
twenty-one dayseach. ‘The milk was analyzed from composite 
samples taken for five days of each week during the several 
periods. The wide and narrow rations as taken from the 
report of the experiment are shown in table 13. While the 
yield of milk obtained from the use of the narrow rations was 
much larger, the percentages of fat do not seem to have been 
materially affected by the rations. The following is taken 
from the summary of the results as given in connection with 
the report of the experiment: 
‘‘The same amount of digestible matter in narrow rations produced from 11.8 
to 12.9 per cent. more milk than a like amount of digestible matter in wide ra- 
tions; narrow rations also reduced the cost of production from 5 to 12 per cent.” 
‘“The average cost of a quart of milk produced with the narrow rations was 
1.81 cents, and with the wide rations 1.97 cents.” 
“The narrow rations produced over the wide rations practically the same 
relative increase in the amount of butter, and the same decrease in the cost of 
production as in the case of the milk.”’ 
‘" Neither the narrow nor the wide rations produced any decided change in 
the composition of the milk.”

of several experiments on the effects of by-products from corn 
(gluten meal, gluten feeds, etc.), as compared with corn meal 
and wheat bran in feeding milch cows are given. ‘The kinds 
and quantities of the various. coarse feeds used in the several 
trials varied considerably, and for this reason it is impossible to 
compare the results strictly on the basis of the proportions of 
protein fed. In all cases, however, the quantities of gluten
