PRACTICE OF TIMBER ESTIMATING 
177 
figures obtained gives its timber stand. In well-timbered 
land two to four “ forties ” a day can usually be covered 
by these methods. 
In recording the results of such an estimate the size 
and quality of the timber are of course noted as well as 
its amount, and general notes on the growth, topography, 
and lumbering conditions of the land are also recorded. 
Following are sample notes of such an exploration:

Twp. 29 N. R. 7 W. 
White Pine, 7 logs average to M.; 30% uppers 
Norway Pine, 8 logs to M. 
Hemlock, 11 logs to M. 
Basswood, 7 logs to M. 
Maple, 14 logs to M.

Land slopes to North. Clay soil; very stony. Two ravines 
running N. W. and S. E. through the “ forty.” Tamarack swamp 
of about five acres in N. W. corner. 
Another method of timber cruising carried out by one 
man alone is described as follows in the “Woodsman’s 
Handbook”: 
A “forty” is 80 rods square. The cruiser who uses the method 
now to be described has found by trial that 500 of his natural 
paces are required to go 80 
rods. He begins at the cor¬ 
ner of a “forty,” say at the 
southeast corner, and steps 
off 125 paces on the south 
line, and so covers one- 
quarter of the side. He then 
stops and, facing north, 
counts the trees of the 
“ forty,” first to an estimated 
distance of 125 paces on the 
right hand, and then to an 
estimated distance of 125 
paces on the left hand, and 
in each case to a distance 
of 100 paces in front of him, thus including the area represented 
in the diagram as Plot I. He then steps north 100 paces, and 
in the same way counts the trees in Plot II, and repeats the opera¬ 
tion successively for Plots III, IV, and V. He has then a complete 
count of the trees on the eastern half of the “forty.” He then 
walks west 250 paces along the north line of the “forty.” Facing 
south, he now counts all the trees on Plots VI, VII, VIII, IX, 
and X in the same way as before, and thus completes counting 
the trees on the entire “forty.”
