manufacturing purposes. Malabar Teak is a few pounds 
heavier per cubic foot than Burmah.* 
I tested, when in Burmah, all the varieties of Teak 
that were then drawn from the Tenasserim forests, and 
found a very considerable difference in their transverse 
strength ; this, however, may probably be attributed to 
the variations of soil, and to the length of fibre in the 
grain. 
Thus the transverse strength of the Thoungyeen was 
proved to be 284 lbs., the Karanee 271 lbs., the Attaran 
201 Ibs., and the Laingbooe only 175 lbs. per square 
inch, the mean strength being 233 Ibs. per square inch. 
The several specimens tried were each of them 2 X 2 X 84 
inches, supported on props 6 feet apart, with the weight 
applied, as usual, in the middle; the result being that 
the Thoungyeen and the Attaran both broke with a long 
splintery fracture, while the others snapped off very 
short. 
In some experiments more recently conducted in 
this country on twelve pieces of Moulmein Teak of the 
same dimensions as above, the results gave, as the mean 
breaking weight, 220 lbs. to the square inch, which is 
less than the average of the four varieties just mentioned, 
and 32 Ibs. below the average of the three first named ; 
the Laingbooe being struck out as not likely ever to be 
imported in sufficient quantities to affect the results 
when applying Teak to building purposes. The dif- 
+ An effort has recently been made to open up afresh the resources of 
the Annamallays ; but owing to the faulty character of the trees, and from 
having to convey the logs a distance of about forty miles by land-carriage 
to a port of shipment, it is thought to be extremely doubtful whether it can 
ever compete in the European market with the Teak timber of Burmah,
