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 Ibs., the Karanee 271 Ibs., the Attaran 

 20 1 Ibs., and the Laingbooe only 175 Ibs. 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 Ibs. 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.
