NUMBER OF TREES OF EACH DIAMETER OF ASH, MAPLE, AND HICKORY 
ON THE WHOLE TRACT. 
Table VILL shows the number of ash, maple, and hickory trees 10 
inches and over in diameter breasthigh over the whole tract. This 
table is given to show, in a general way, the amount of timber avail- 
able from these species, lack of volume tables making it impossible to 
give their volume in board feet.

COMPARISON OF TWO-THIRDS AND DOYLE RULES. 
Table IX shows the total yield for each holding from the three most 
important species—loblolly pine, longleaf pine, and -cypress—scaled 
both by the two-thirds and by the Doyle log rules. In each case the 
scale by the two-thirds rule is far in excess of that by the Doyle rule.
