In Table XV it is seen that in every case the crops were produced 
at the lowest cost on the farms having the more favorable sizes. In 
addition to this, the average value of the dwelling was highest on 
these farms, and not only were the dwellings the most valuable, but 
these farms could also best afford them, for the value was only one 
and one-half times as great as the farm income, while on the farms 
of the groups having the least favorable sizes, the value of the dwell- 
ings was twice that of the farm income.

Farms having the more favorable sizes had a lower cost per pro- 
ductive man day and mule day of work, and also higher yields of 
crops than the others. (See Table XVI.) Each productive man 
day's work cost $1.18 in the A groups as compared with $1.30 in the 
C groups. The cost per productive mule day in the A groups was 
$1.34 as compared with $1.36 in the C groups. These differences 
were not great, but they show greater efficiency in the farms with 
the favorable sizes.
