WHITFORD. 
But when judged from the standpoint of size a quite different im- 
pression is obtained. By that standard, we should note that of the 1,160 
trees only 826 (about 71 per cent) reach merchantable size (30 centi- 
meters in diameter), that 409 of these (35 per cent of the whole number 
or 50 per cent of those that may reach merchantable size) are of one 
botanical family (the Dipterocarpaceae) . 
Table II shows the species and number of the dipterocarps found 
in the above mentioned plot.

Total „ 
It will be seen that of the Dipterocarpaceae , two species, Dipterocarpus 
grandiflorus and Shorea polysperma , have 316 representatives or about 
38 per cent of the total number of trees that may reach a merchantable 
diameter of 30 centimeters. 
The following table shows the proportion of the other trees mentioned 
in Table I by families that may reach merchantable size when mature.
