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:
