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 breasthigh 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.
