CULTIVATION OF RHIZOPHORA 105 
2 or 3 centimeters in diameter at the base, are often sold to 
planters of ikmo (betel pepper) at 12 pesos per 100. 
The very rough pieces, particularly those that occur where 
the prop roots are joined to the trunk, are used in making 
charcoal. The bark is also occasionally used for cooking, espe- 
cially in the roasting of corn. This use does not seem to be 
general enough to have fixed a market price. 
Ranger De Mesa has made a careful count of the number of the 
trees on several plots in bakauan plantations. The results are 
given in Tables XII to XIV. These tables show the number of 
trees of different lengths and diameters and the volume according 
to the length and diameter of the trees, also, the total number of 
trees and the total volume, and the percentage of trees and volume 
in the different length classes. In the lower portion of the table 
are shown the number, grades, and volume of the rajitas ob- 
tained by cutting and ‘splitting the trees.
