which stood a tensile strain of 6,790 Ibs. per square inch. He 

 also made six tests for transverse stress which gave 8,884 Ibs. 

 per square inch, whilst the crushing stress on cubes 2 inches 

 by 2 inches gave an average of 5*33 tons per square inch. 



Camphor is found in small crystalline masses in natural 

 cavities in the wood. This is very much prized by the 

 Chinese, but is not the camphor of commerce. 



Weight about 47 Ibs. per cubic foot. 



Tampenis (Sloetia sideroxylon), a well-known tree from 

 60 to 80 ft. high, which produces one of the best timbers of 

 these parts, with yellowish white sapwood, and heartwood 

 dark reddish brown, is hard, resinous, and durable, and 

 is said to be proof against fungus and termites. It has 

 irregular, dark, somewhat broad, but distinct rings, and the 

 trunk is unbranched for the greater part of its height. 



Weight 67 Ibs. per cubic foot. 



Champak (Magnolia champaca), the Malay name for a tall 

 evergreen producing a hard, durable, and ornamental 

 wood of yellowish brown colour and even grain, is largely 

 used in India for planking, panel, carriage work, and furni- 

 ture. The tree is much cultivated round about Jain and 

 Hindoo temples, and the wood made into beads and neck- 

 laces, which are sold to pilgrims. It is called Titu Sepa in 

 Assam. Resistance along fibres as tested by Prof. Unwin 

 753 Ibs., crushing stress 1'57 tons, and transverse stress 

 3'48 tons per square inch. 



Weight about 41 Ibs. per cubic foot. 



Meranti (Hopea meranti) grows to a height of 100 ft. with 

 a straight trunk 3 ft. in diameter. It is also fairly abundant 

 in Malacca and Perak. The stem and branches when cut 

 yield a quantity of damar, a kind of gum, of considerable 

 commercial value at Singapore. The timber is a soft red
