A FARM MANAGEMENT SURVEY IN BROOKS CO., GA. 
25 
Increasing the amount of productive labor per mule reduces the 
cost per day of such labor, resulting in a lower cost of production 
and larger farm profits. This is shown by Table IX, in which the 
farms are grouped 
on the basis of the 
number of days of 
labor per mule. On 
the group of farms 
reporting the least 
productice labor per 
mule, or an average 
of 62 days per year, 
the cost per day of 
mule labor amounted 
to $1.70, which daily 
cost decreased regu- 
larly to 72 cents on 
the group reporting 
the most labor, or 172 
days per mule. The 
striking relation be- 
tween increasing days' 1 
work per mule and 
decreasing cost per 
day of mule labor is 
shown by the curve in 
figure 12. 
It may Well be asked FlG - 12— Relation o^daystf Productive labor per mule to 
by what means some 
of the farms provided so much more employment for the work stock 
than did others. The data in Table X indicate that the area culti- 
vated per mule is the most important factor.
