sicler only examples like satinwood, rosewood or teak and give little 
or no account of the woods of the great family of Diptero carp acece, 
which furnishes much the largest part of the timber of this part of 
the world. This is as unreasonable as it would be to take a few of the 
furniture woods of North America, as black walnut ( Juglans nigra ) 
or the wild black cherry ( Prunus serotina), as representative of the 
woods of the country. In the eastern tropics, the woods of the family 
Dipterocarpacew are to the trade what the pines, spruces, firs, hemlocks, 
oaks and beeches are to the trade in temperate North America and 
Europe. This family, while it supplies many valuable hardwoods, sup- 
plies also the most widely used soft and medium grade woods of the 
eastern tropics. So wide is its distribution and so general the use of its 
wood that I believe that all other woods could be spared from many 
eastern markets without seriously hampering work or affecting prices. 
OBJECT OF THIS WORK. 
There is a great deal of confusion in the use of the common names 
of the different woods. Many of the woods of the region are of wide 
distribution; but, they are known by different names in different coun- 
tries. This work is undertaken with the object, first, of correlating Phil- 
ippine woods with the related or identical forms in other sections and 
then of calling attention to the structure, uses and distribution of the 
eastern woods. 
DEFINITION OF THE INDO-MALAYAN REGION. 
This is taken to include all of Ceylon, British India, Burma, the 
Andamans, Siam, Cochin China, the Malay Peninsula, Sumatra, Java, 
Borneo, the Philippines, and all of the Malay and Indian Archipelago 
down to New Guinea. In other words, it is meant to include nearly all 
of the tropical East. It constitutes a region which geographically and 
commercially is quite distinct. Japan with its temperate-zone woods 
constitutes a very distinct group. Australia is also very distinct, with 
its eucalyptus and other characteristic woods. Wherever woods from 
either of these regions come into tropical markets to any considerable 
extent, they are considered in this paper. The number of cases in which 
woods of the temperate regions are of commercial importance in the 
eastern tropics is really very small. First of all would come the use in 
India of the woods grown in the temperate forests of the lower Himalayas. 
After this come the various eucalyptus species exported from Australia, 
the Oregon pine from the United States, and the camphorwood from 
Japan and Formosa. 
REVIEW OF PREVIOUS WORK AND ACKNOWLEDGMENTS. 
In the course of the comparative study of the woods of this region, 
collections of botanical and commercial material have been made in some 
of the countries considered and material from other countries has been
