The foregoing is an excellent description. 

 There are several rules used by timber cruisers 

 for estimating the amount of lumber in a tree. 

 The unit; the 'board foot,' is one square foot 

 one inch thick. The Doyle rule, which is very 

 generally used, figures as follows : Deduct four 

 inches from the diameter of the log as allow- 

 ance for slab, square one-fourth of the remain- 

 der and multiply by the length of the log in feet. 

 The result is the board contents. There is also 

 the Ropp rule, the Spaulding rule, the Doyle 

 and Scribner rule, the Scribner rule and the 

 British Columbia rule. In addition there are 

 modifications and combinations of these rules. 

 They all depend entirely on the cruiser using 

 them and the nature of the timber. The esti- 

 mates should be carefully verified before mak- 

 ing the loan.
