116 TIMBER AND TIMBER TREES. [ CHAP. 
but, as the evidence of its utility goes no farther than to 
show the advantage gained in being able to float the 
timber immediately it is felled, it seems probable that 
before long it will be given up entirely. Experiments 
have been made in Burmah* in felling green Teak, but, 
as out of I00 trees so felled, twenty-seven in number had 
extensive heart-shake, and ten others were less seriously 
affected, it was thought desirable to carry the experi- 
ments farther before determining the matter in question. 
Although imported and known under the general 
name of Teak, there are many varieties, if not distinct 
species of it, the Burmese naming those found in their 
country after the districts in which they grow; thus, in 
the Moulmein district there are the Thoungyeen, the 
Salween, the Karanee, the Attaran, and the Laingbooe 
Teak ; and in the Rangoon district, the Irrawaddy Teak, 
all differing slightly in colour, grain, texture, and specific 
gravity. 
The Thoungyeen and the Salween Teak timber are 
of a yellowish-brown colour, smooth and uniform in their 
texture, with a fine long grain. The Karanee Teak has 
alternate shades of dull brown and yellow colour, the 
grain being close and long, with occasionally a rowiness, 
or figure, in it, and is also very free from defects. The 
Attaran Teak is rather stunted in growth compared with 
the varieties just mentioned, but is of fully the same 
circumference. The wood is brownish in colour, dense, 
hard, and resembles very much the Malabar Teak. It is 
heavier than either the Thoungyeen or Karanee, and is 
also coarser and more knotty, owing to the branches 
occurring lower down the stem. Some of these, from 
accident or otherwise, get broken off, and defects, arising
