THIS VOLUME TABLE 



is intended to aid in determining the percentages of the 

 different grades of logs in any stand of timber. The figures 

 given indicate the amount of lumber in trees of different 

 sizes and forms and the percentage of the contents of each 

 tree that is contained in each 32-foot log in that tree. 



EXAMPLE: 



Sample Tree, 128 feet or four logs in length. 



ButtDia. TopDia. Cooteats Percent. Percent. Percent. Percent. 

 In inch, in Incb. in M ft. 1st log 2nd log 3rd log 4th log 



48 24 6592 40 28 20 12 



Therefore : If a tree contains one Flooring log, two Merchant- 

 able logs and one Common log then forty per cent, of the 

 contents of the tree is Flooring, forty eight per cent, is 

 Merchantable and twelve per cent, is Common. Similarly, if 

 this tree contains one 16-foot Flooring log, two and one-half 

 Merchantable logs and one Common log then the percentages 

 will be 20, 68 and 12, respectively, and so on through all the 

 varying forms of trees. 



To apply the rule in cruising, determine the percentages 

 of the different grades as contained in a given percentage of 

 the trees on each forty acres by selecting, for instance, an 

 average tree on each tally and carefully determining the 

 percentage of the different grades of logs contained in these 

 sample trees and applying the average to all trees on the forty.
