PTEBIDOPHYTA. 



The only use to which members of this group are put as timber seems 



to be in the occasional use of the trunks of tree ferns as the corner posts 

 of native houses. This is reported from Benguet in northern Luzon 

 and from New Guinea. Such a use could only be very local, where tree 

 ferns were very abundant or where other timber was scarce. The con- 

 venient size and location of these stems will probably account for 

 their use. 



Among the Hagobos, on the cast slope of Mount Apo, in Mindanao, the 

 tree ferns are used very extensively, in preference to other woods. They 

 are said to be very durable; and, certainly, their shape is such as to 

 make it possible to utilize them with very little effort.

This group, which contains the coniferous trees, furnishes the greatest 

 part of the timber supply of the world, but it is only scantily represented 

 in the eastern tropics. There are a few representatives which are used 

 to some extent, as the Benguet pine of nortbern Luzon, the pines and 

 cedars of the Himalayan slopes and some of the species of Podocarpus, 

 which are rather widely distributed. However, none of these are used to 

 such an extent as to be of very general interest in this region. Wherever 

 met with, the wood may be readily distinguished by its nonporous 

 structure.
