It will be seen by the above that in the narra type approximately 22 
trees out of every 66 and in the hagachac type 25 out of every 60 trees 
per hectare are dipterocarps or respectively 33.11 per cent and 41.50 
per cent of all trees over 40 centimeters. 
Unfortunately for the purposes of this paper the volume tables pub- 
lished in Bulletin 6, showing the cubic contents of timber per unit of 
area do not include all of the species. But the results given below show- 
ing the proportion of dipterocarps are not far from the actual proportion, 
for a large per cent of the species not mentioned show a maximum 
diameter of not over 45-50 centimeters and short boles usually one-fifth 
to one-third the length of the boles of the dipterocarps. Pour species, 
Dracontomelum , agupanga and two species of Canarium mentioned in 
the stand tables are not included in the tables below. Agupanga has a 
short bole usually about one-fifth the length of any of the dipterocarps 
of the same diameter. While the bole of the Canarium is somewhat 
longer yet the number of trees per hectare is small. Neither agupanga nor 
the Canariums attain the maximum diameter of the dipterocarps. Dra- 
contomelum dao on the other hand, reaches a maximum of 140 centi-
