VOLUME OP ENTIRE STEM IN €L T BIC FEET. 



The measurements for volume of entire stem are complete enough 

 for accurate stem volumes for the Black Hills and for California. The 

 Arizona data contained measurements on the merchantable part of 

 the tree only; hence there is no table of stem volume for Arizona. 

 The Black Hills table will apply, with possibly a small deduction. 



The volumes for the Black Hills (Table 17) were made up from 

 measurements at 4-foot points for the smaller diameters and 10-foot 

 points for the larger. The California analyses had 10-foot tapers. 

 Table 18 was constructed entirely from the best part of the California 

 data and its basis is considerably less than the corresponding board- 

 foot table. The tops of the trees were figured as cones. In the 

 California data the taper was not carried as far into the top (except 

 for the 13., 14, and 15 inch trees) as that of the Black Hills; hence the 

 part figured as a cone was longer and a larger error was introduced 

 in the volume. However, this would not materially reduce the differ- 

 ences between the two tables. For the 13, 14, and 15 inch diameters 

 the tapers were carried to equal points, and though the California
