been idle a large portion of the year and would have made propor- 
tionately smaller incomes. 
The classes of feed crops grown and their relative acreage are shown 
in Table LITI. On the average for all the farms there are grown, — 
for each animal unit kept, corn, 0.62 acre; small grain for feed, 0.18 
acre; and hay, 1.23 acres; a total of 2.03 acres of feedable crops per 
animal unit. In addition to this we have 1.18 acres of pasture per 
animal unit, a total of 3.21 acres of land devoted to pasture and feed- 
able crops per animal unit.

The last two lines of this table show that a considerable proportion 
of the feedable crops are sold, the amount realized therefrom being 
considerably greater than the amount expended for feedstuffs bought. 
PRODUCTION AND UTILIZATION OF SILAGE. 
Of the 378 owners operating their own farms, 56 had silos (see 
Table LIV). Silage is fed an average of 203 days during the year, 
or about 63-months. The average amount fed per day, as estimated 
by 24 of the farmers feeding this material, was 40 pounds per cow. 
Estimates of the amount fed per day are presumably based on occa- 
sional weighings of the feed given. But in estimating the amount 
of silage stored on the farm it is customary to base estimates on silo 
capacity as given by King’s rules. The farmers’ estimates of the 
amount of silage stored by them amount to 46 pounds per head per 
day for the usual feeding period, a difference of 13.1 per cent of the 
amount stored. If both these estimates are approximately correct, 
they indicate an average loss of silage stored amounting to 13 per 
cent.
