It will be noticed that while the table as a whole is consistent, there 
are two slight irregularities, namely, in the 19 and 22 inch classes. 
These were caused by the fact that in these two classes there chanced 
to be an unusually large number of trees which, when put through the 
saw, were found to contain defects not apparent in the log. In select- 
ing trees everything was taken which did not show an advanced stage 
of red heart or contain very crooked logs. In tallying the lumber 
that came out of these trees it was assumed that the logs were sawed 
to the best advantage; if, for example, a siding that would have made 
a board 12 inches in width was ripped by the edgerman into two 6-inch 
boards, it was, nevertheless, tallied as a 12-inch board. No account 
was taken of lath made from slabs. With these exceptions, the table 
may be taken as approximately correct for the values of sound trees 
on the Coosa County tract. In order to determine the profits from 
these trees, the stumpage value, cost of logging, transportation, and 
manufacture must, of course, be deducted. Under favorable con- 
ditions these items do not exceed $7.75. 
The table shows in figures a fact that is known only in a general 
way among lumbermen, namely, that the higher the cutting limit the 
higher the profit per thousand feet, but the lower the profit per acre. 
Cutting to a diameter limit of 16 inches would bring more profit per 
acre because it would remove more timber, but it would be taking 
some timber which, when sawed into lumber, would be worth at 
present about 50 cents a thousand feet less than that from 18-inch 
trees. In other words, the quality of the output would be lowered 
slightly in order to obtain a somewhat larger cut. If, on the other 
hand, trees under 18 inches in diameter are left to grow to a larger 
size, a second crop will be produced which, on a basis of quantity 
alone, will yield 6 per cent compound interest on the investment, and
