"When Ave study the cost of cotton per acre, we find the low-yielding 

 group showed a cost of $29.09 on the small-size, $25.54 on the medium- 

 size, and $23.58 on the large-size farms ; which was $5.51 less on the 

 large farms than on the small farms. In the yield-per-acre group 

 of one-half to two-thirds bale the cost was $34.76 on the small farms, 

 $31.69 on farms of medium size, and $30.28 on farms of over 250 

 acres, which was $4.48 less on the large farms than on the small farms. 



On the farms with the highest yields of cotton the cost per acre 

 was $41.76 in the group with 100 acres and less, and then as the size 

 of farm increased the cost decreased until in the largest-size group 

 it was $34.33 per acre. This was $7.43 less on the large farms than 

 on the small farms. 



There was a greater reduction in the cost per acre between the 

 small and the medium farms than between the medium and large 

 farms. The reduction in favor of the medium-size group over the 

 smallest-size group was $3.55, $3.07, and $4.01 in the respective yield- 

 per-acre groups, while the reduction in favor of the largest-size 

 group over the medium-size group was only $1.96, $1.41, and $3.42 in 

 the respective yield-per-acre groups. 



THE EFFECT OF YIELD PER ACRE UPON THE COST OF PRODUCTION. 



In Table XXXI the farms are separated into three groups that 

 may be used in studjdng the effect of yield per acre upon the cost of 

 production. 



On farms with 100 or less acres the cost per pound of lint cotton 

 was 13.84 cents when the yield was one-half bale, 11.97 cents when the 

 yield was from one-half to two-thirds bale, and 10.58 cents when the 

 yield was over two-thirds bale. This shows the cost per pound 3.26 

 cents less on the good than on the poor yielding farms. 



On farms of 101 to 250 acres the cost per pound of lint was 12.41 

 cents when the yield was poor, 11.05 cents with a medium yield, and 

 9.52 cents when the yield was good. This shows the cost per pound 

 2.89 cents less on the good than on the poor yielding farms. 



On the farms of over 250 acres the cost per pound of lint was 

 12.27 cents when the yield was poor, 10.10 cents when the yield was 

 from one-half to two-thirds of a bale, and 9.52 cents when the yield 

 was good. This shows the cost per pound 2.75 cents less on the good 

 than on the poor yielding farms. 



Thus in the respective size groups cotton was produced at 3.26 

 cents, 2.89 cents, and 2.75 cents per pound less on the farms having 

 good yields than on the farms having poor yields. 



With medium yields per acre the cost per pound was 1.87 cents, 

 1.36 cents, and 2.17 cents less for the respective size groups than with 

 poor yields, but with good yields the cost per pound was only 1.39 

 cents, 1.53 cents, and 0.58 cent less for the respective size groups than 

 with medium yields. The cost was almost 2 cents per pound less with
