IDERING the vast importance of the timber trade in the 
comimiarse, not only of this country but of the world at large, it 
is somewhat surprising that the literature of the subject is chiefly 
confined to small contributions dealing for the most part with one 
particular branch of a vast study. It is true that we have a great 
Forest Conservancy Department in India, and many excellent 
bab ave appeared in connection with the useful work there 
rried on—such, for instance, as Gami ble’s Manual of Indian 
Guiana—little - eibthiets has been dui atthier towards olcattig —

known to produce many excellent and beautiful woods, specimens 
of which have been shown at the several International Exhibitions, 
and sa since found a permanent home in the great wood collections

The interest posses to a subject of such widespread and 
real importance ensures for any literary contribution to its 
knowledge a we dich from the large number of persons whose 
interests in many ways are so intimately connected with timbers.

study. This is further proved by the excellence of the 186 photo- 
micrographs with which the work is illustrated, and which, .
