294 ReEporT oF THE FARM SUPERINTENDENT OF THE 
The milk yielded during the ten days March fifth to March 
fourteenth was 380 pounds, 14 ounces, and for the last five days — 
averaged 39 pounds 33 ounces. | 
During the succeeding ten days, when the water drank was 
60° F. lower the total yield was 375 pounds, 8 ounces, and for the 
last five days averaged 37 pounds, 9 ounces. 
This gives for the warm-water period an excess of 1 pound 104 
ounces of milk per day. This period required 6.2 ounces. less of 
hay per day. The temperature of the stable for that period taken 
twice daily was 6° lower than for the following one, while the 
outside temperature was 9° F. lower than when the cooler 
water was given. 
Against these items in favor of warming water are to be placed — 
the cost of warming, and the decrease in milk yield from the date | 
of calving which in this case can be discarded because the cow 
had not at the end of this experiment reached her maximum flow 
of milk, and the cold water period came last during the period of 
gain and with warmer environment. 
The question resolves itself into whether it is cheaper to warm 
the water by animal or artificial heat. Its solution in favor of 
one or the other side depends on circumstances at the place of 
trial. If the cows were warmly housed and not exposed to cold 
weather it might be profitable to warm the water, when with the 
same cows, barn and care, if they were turned out in the yard for — 
daily exercise, more food would be required as fuel, on account of ~ 
the exposure, than could possibly be saved by warming the water. 
More time and animals are required for a complete trial of this 
question.

SUBSOILING EXPERIMENTS. 
In order to make a trial of the benefit of subsoiling, one acre 
was subsoiled in the oat field and another acre in the corn field. 
Slight gain by subsoiling oats.—The acre subsoiled in the oat 
field was so chosen that one-half was on corn stubble which had 
not been disturbed until the subsoiling, and the other half had 
been fall plowed after producing a crop of peas and oats. The 
whole field was plowed about seven inches deep, and a subsoil 
plow was run in the bottom of the furrow to a depth of about six — 
inches. The soil was well fitted for seed and Welcome oats were ~ 
drilled in at the rate of two bushels per acre. The Empire State — 
brand of Read & Co.’s fertilizers was drilled in with the oats, 
using about 400 pounds per acre. Two acres were measured for —
