BULLETIN 316, U. S. DEPARTMENT OP AGRICULTURE. 



VOLUME IN BOARD MEASURE. 



The following tables are based on taper tables constructed from 

 measurements of 256 selected trees, taken principally in Arkansas, 

 Mississippi, and Louisiana, with a few in Missouri and Indiana. All 

 measurements were taken on trees less than 60 years old, growing on 

 rich alluvial bottom lands. Practically all the trees measured were 

 felled in logging operations. The figures in heavy-faced type indi- 

 cate the volumes of trees of average heights. Table 5 shows the 

 volume based on diameters breas thigh from 14 to 36 inches, and 

 heights 10 feet apart from 60 to 130 feet. The top diameter limit 

 runs from 10 inches in the 14-inch trees to 26 inches in the 36-inch 

 trees, giving very incomplete utilization. Table 6 shows the volume 

 based on diameters breasthigh and number of 16-foot logs per tree. 1 

 The trees forming the basis of both tables were scaled with the Scrib- 

 ner Decimal C rule.
