VOLUME TABLES. 



Table 22 shows the contents in board feet of trees of different diameters and contain- 

 ing different numbers of 16-foot logs. For trees from 7 to 9 inches in diameter, inclu- 

 sive, and for all one-log trees, the table is based on 555 trees measured in Deerlodge 

 County, Mont., with an average stump height of from 0.5 to 1 foot, and an average 

 top diameter inside the bark of 6 inches; for all trees 10 inches and over in diameter 

 and containing more than one 16-foot log, it is based on 1,808 trees measured in Galla- 

 tin County, Mont., with an average stump height of from 1.4 to 2.2 feet and an average 

 top diameter inside the bark of from 6.2 to 6.6 inches.

Table 23 shows the contents in cubic feet and in board feet of trees of various diame- 

 ters and total heights in the Deerlodge and Gallatin National Forests, Mont. The 

 volume in cubic feet includes the entire contents of the tree (exclusive of bark) from 

 the top of the stump to a top diameter of from 2 to 3 inches inside the bark. Ths 

 volume in board feet shows the amount of scale material included in the tree to a top 

 diameter of 6 inches inside the bark. Besides the board-foot contents there is always 

 a small amount of additional material in the tops which can be used for lagging poles, 

 converter poles, cordwood, etc., when such material is marketable.
