422 PAPER PULP 
and other species of the same genus is collected in considerable 
quantities and exported to Japan where it is said to be used for 
the manufacture of bank notes and other strong papers. These 
plants are small bushes which are scattered in thickets through- 
out the Philippines. Most of the bark collected comes from the 
vicinity of Mount Mayon and from Mindanao. 
In the Philippine Islands there are large numbers of plants 
with strong bast fibers. Some of these might be useful for 
high-grade paper or for strengthening paper made from weaker 
material. These barks are discussed in the section on fibers. 
In:Table V are given the dimensions of the ultimate fibers of 
some of the plants previously discussed.

As far as we now know, the Philippine forests in general do 
not offer particularly favorable conditions for the gathering of 
pulp material. This is due to the fact that the composition of 
the forests is very complex. On one quarter of a hectare of 
virgin forest on Mount Maquiling there were 92 different tree 
species. In an over-cut area of the same size there were 129 
different species. However, conditions are not always as un-
