The specimens experimented on measured 3 ft. by 1 1/2 ft. by 11/2 ft.
Name of Wood. | Average weight per cub. ft. | Deflection in in. | Weight producing deflection in 11). | Breaking weight in lb. | Remarks. |
Billian Chingy .. | 60 | 5/10 | 408 | 913 | Hard, close-grained, fine-fibred, but very much inferior to Billian Wangy; of a brownish grey colour; readily attacked by insects and dry rot; used for flooring joists. |

Piles which have been in the ground for 100 years have been found in a good state of preservation. One of the few woods which will really stand the climate of India. Colour dull grey. |
Jolotong | 29 | 5/8 | 280 | 732 | Well adapted for patterns and mouldings, excellent for carving purposes; grain very close, scarcely any knots, colour whitish yellow, fracture short, but not very durable. |
Name of Wood. | Average Weight per cub. ft. | Deflection in in. | Weight Producing Deflection in lb. | Breaking Weight in lb. | Remarks. |
Krangee .......... | 77 | 5/8 | 980 | 1339 | Very hard, close-grained, well adapted for beams of every description. White ants or other insects do not touch it. Well adapted for piles for bridges in fresh or salt water; also used for junks' masts; stands well when sawn, ranks with Tampenis for durability. Fracture long, fibres tough, colour dark red. |
