DISCUSSION OF LOG RULES.

TABLE 4. (A transformation of Table 2.) Average values in board 

 feet, as shown by the Vermont Log Rule, contained in merchantable 

 portion of immature western yellow pine trees of different merchant- 

 able lengths and diameters breasthigh. 



TABLE 4. 



This table was obtained by transforming the values in Table 2, based 

 upon the Spaulding Log Rule, to values shown here based upon the 

 Vermont Rule. The transformation was made in the following manner : 

 To each value shown in Table 2, twice the merchantable length indicated 

 at top of table was added to each of the values. Each of the new values 

 thus obtained was divided by (1 .266) and multiplied by (1 .363). 

 The resulting values form the above table, and include all logs contained 

 in the merchantable lengths. This table is the same as would have 

 been obtained had the results been based directly upon the woods 

 measurements.
