Dot WORKING PLAN, FOREST LANDS IN ALABAMA. 
CHARACTER OF SURVEY WORK DONE. 
The preparatory field work, which occupied a party of nine men on 
the ground for a period of five months, consisted principal.y in the 
running of valuation surveys, the making of stem analyses, a study 
of the logging methods of the Kaul Lumber Company and their effect 
on the future productivity of the forest, and a study of the damage to 
the forest by fires and of means of preventing them. A total of 5,375 
acres of valuation surveys were run—1,791 in the Coosa County tract 
and. 3,584 in the Bibb County tract. 
In addition to the field work a special study was made at the mill at 
Hollins to determine the value of the lumber sawed from trees of 
different sizes. 
The volume table for longleaf pine, numerically and commercially 
the most important tree, is based upon measurements of 472 trees and 
ring counts of 526 stumps. For the loblolly pine, measurements of 
volume and rate of growth were obtained from 128 trees. Asa means 
of comparison with the figures obtained from the measurements of 
felled timber, height measurements of standing trees were taken with 
a hy Pecmeter in various parts of both tracts. 
The map of the Coosa County tract is a combination of the field 
notes and township plats of the Public Land Survey, the topographic 
sheets of the U. S. Geological Survey, and the topographical notes 
from the valuation surveys made by the Forest Service. The map of 
the Bibb County tract is a combination of the Public Land Survey and 
the valuation survey notes. 
The yield tables were compiled from the figures obtained from the 
valuation surveys and the stem analyses. Each tract was divided into 
blocks according to differences in character, composition, and condition 
of the forest. A stand table, giving the average number of trees per 
acre of each diameter class, was worked out for each block. 
The tables of the present yield, giving the average per acre in board 
feet for each block, are combinations of the stand tables and the volume 
tables obtained from the stem analyses. 
The tables of future yield were obtained by combining the tables of 
the stand, volume, and rate of growth. 
It seemed best not to attempt to survey every acre owned by 
the company, nor to survey its lands only, since both its tracts 
are very much broken up by interior holdings, some of which con- 
tain good timber, and these the company expects gradually to 
buy up. To have surveyed those areas only to which the company 
at the present moment holds the title would have resulted in leaving 
out of consideration a great deal of land in which it has almost the same 
interest as in that which it actually owns, and would have made it 
impossible to compile anything but a very incomplete and dis-
