The exact size of diameter separating the timber of a stem and es- 
pecially the merchantable timber from the small wood or firewood will 
vary in different localities according to the different requirements of the 
market ; but for statistical purposes it is essential that a definition of 
universal applicability be accepted for timber, and it is suggested that 
this be fixed for India at G inches diameter or 18 inches girth* : the defi- 
nition of “merchantable timber” necessarily varying in each locality. 
The merchantable timber obtained from a tree or wood at different 
ages is usually graded into various classes which may vary indefinitely 
according to market requirements from one locality to another. In 
India few descriptions of fashioned Sal timber are exported from the 
Government reserves ; the stem being either made into rough-squared 
logs of convenient lengths, or sawn into sleepers or scantlings. Data 
giving for various localities the average outturn in cubic feet of rough- 
squared logs, planks, or sleepers, for trees of different girth classes have 
not been systematically collected ; and only a few unreliable figures are 
at present available. 
In the Garhwal Forest Division, United Provinces, 3,238 Sal trees, 2 
to 2^ feet in diameter, measured by Mr. Dansey, yielded the following 
lengths of timber : —

*For statistical purposes, all Forest Researcli Institutes of Europe have agreed to 
take a girth of 2 decimeters { =7 874 inches) as separ.ating timber (Derbholz or Bois fort) 
from small wood or firewood (Reisholz or Menu bois, ramiers).
