in short radial lines, and very fine medullary rays. It is 
used largely for planking. 
Weight about 45 lbs. per cubic foot. 
Penak Chengai {Balanocarpus maximus) is a very large 
tree, which is found also in Johore ; the wood is yellowish 
brown, but darkens with age, and is hard and durable. The 
rays are very distinct. It is excellent timber for general 
building work and boat-building. There are several 
varieties of the tree, but this is considered the best. 
Weight 59 lbs. per cubic foot. 
Kranji Sepan [Dialiim platt/sepalium) . — The Malay name 
Kranji covers the seven species of Dialum found in the 
Malay Peninsula, all of which yield very hard, durable 
timber. The heartwood is of dark brown colour, like 
mahogany, the sap of light colour ; the wood is heavy, 
tough, and extremely durable, with a close grain. Used for 
ship and house building in Borneo. The best of it is now 
rare. Laslett tested a piece which proved equal to a crush- 
ing strain of 10,920 lbs. per square inch. 
Weight 67 lbs. per cubic foot. 
Teng Mang {Dryohalanops aromatica), the camphor tree of 
Borneo, is also found in Sumatra and elsewhere. It 
attains a height of 150 ft. with 3 to 4 ft. diameter, and 
often with straight unbranched trunk for 80 ft. The 
timber is a deep red in colour, tough, close in texture, and 
often cross-grained ; the sapwood is light in colour, but in 
the larger trees there is very little of it. The wood darkens 
with age, and has a strong smell of turpentine, due to the 
oil of camphor contained in the resin. It is one of the best 
of Malay hardwoods, very durable, and when polished 
resembles mahogany. It is used for general building 
work. Laslett tested small pieces 2 inches by 2 inches
