from tables of average composition of feeding stuffs. Average 
factors of digestibility from American digestion experiments 
were used in all cases. The quantity of protein in the narrow 
rations (2.37 pounds per day) is about double that contained 
in the wide rations (1.16 pounds per day). In the case of 
both lots of cows the narrow rations gave a considerable increase 
of milk, amounting to an average of 1.4 pounds per day in the 
case of lot A, and 2.6 pounds in the case of lot B, while the 
average percentages of fat for both lots of cows were about six- 
tenths higher in the case of the cows fed the narrow rations. 
The exact figures are: Lot A, wide ration, 3.40 per cent.; nar- 
row ration, 3.98 per cent.; and lot B, wide ration, 2.42 percent 
and narrow ration, 3.92 per cent. ‘The proportion of fat in the 
total solids was also considerably greater in the case of the 
cows fed the narrow rations. In the case of lot A the fat was 
28.7 per cent. of the total solids for the wide ration and 32.0 
per cent. for the narrow ration; and in the case of lot BrownG 
per cent. for the wide and 30.8 per cent. for the narrow ration. 
L:xperiment at the Maine State Experiment Station.*—Prof. 
W. H. Jordan has reported experiments on the effect of wide 
and narrow rations with three cows. He writes: 
‘<The experiment with cows, the results of which are given in this connection, 
was planned with references to changes in the ration so radical as to induce if 
possible, corresponding variations in the milk. * *~ “The rationse 
this experiment were made to differ very widely in the relation of the nitrogenous 
to the non-nitrogenous nutrients.” 
The experiment was begun with four cows, but one was 
dropped out and results are reported from only three. ‘The 
three feeding periods covered thirty-five days each. ‘The first 
week of each period was omitted from the final results. “The 
milk was analyzed for the last five days of each Be gises The
