In hardwood timber and southern pine growing in open scattered 
stands, there is not only great variation in total height of trees on 
the same tract but the number of merchantable logs in a tree does 
not depend alone on its height, but also on the form of the crown 
and clear length. In very close estimating of valuable timber on 
tracts as small as 40 trees it may become necessary to tally the 
merchantable length of every tree on the portion covered. 
Some cruisers classify the trees as they measure them into two- 
log, three-log, four-log trees, etc. They have on their tally sheets 
several columns for each kind of tree, as follows: 
WHITE PINE. | HEMLOCK. |
