INTEREST RETURNS. ! 67 
From an examination of Table X XIX it can be seen that although 
the present yield per acre on Blocks I, III, V,and VI is considerably 
higher than that of the Coosa County nae the second crop promises 
to be somewhat lower. Cutting to a 16-inch diameter limit, the 
present yield will amount to 7,646 feet, and at the end of 30 years a 
second yield of 2,615 feet can be obtained. Cutting to an 18-inch 
diameter limit, the present yield is 7,176 feet, and the future yield, at 
the end of 20 and 30 years, respectively, will be 2,829 feet and 5,645 
feet. This difference in proportion between present and future yields 
is of course readily explained by the fact that the composition of the 
forest is different. There are more trees over and fewer trees under 
12 inches in diameter breasthigh on the Bibb County tract than in 
Coosa County.

INTEREST RETURNS. 
In spite of the slightly lower yield in board feet to be expected in 
the second crop, the returns on the investment at compound interest 
are very nearly the same as those estimated on a second crop on the 
Coosa County tract. The results of the financial calculations given in 
Table XXX show that a cutting limit of 18 inches in diameter breast- 
high will give the best returns. ‘
