willows: their growth, use, and importance. 



FORM TABLES. 



21 



The foregoing volume tables were made by scaling the average 

 tree in each diameter and height class, and are intended to show 

 the volume of the trees according to the log scales most commonly 

 used both under the present system of utilization and under a closer 

 system. In each case, however, the diameter limit established is an 

 arbitrary matter and the volume shown applies only for the par- 

 ticular log scale used. In the following form tables the actual 

 average taper measurements are given, and from these it is possible 

 to construct volume tables for any log scale and any degree of utili- 

 zation. Moreover, tables can be constructed to show the contents 

 of the trees not only in board feet but in any other unit, such as 

 cordwood, posts, etc., that may be desired. In the form tables are 

 shown diameter classes from 8 inches to 36 inches at intervals of 1 

 inch and height classes from 60 to 130 feet at intervals of 10 feet. 

 The heights above ground represent 16.3-foot logs and half logs 

 plus a stump height of 1 foot. The tables are based on the meas- 

 urement of 252 trees in Indiana, Arkansas, Missouri, Louisiana, 

 and Mississippi.
