Terminalia glabra weight 55 lb.; elasticity, 3905; cohesion, 20,085 lb.; strength, 840 lb.; furnishing a very hard, durable, strong, close and even-grained wood, of a dark-brown colour, obtainable in large scantling, and available for all purposes of housebuilding, cart-framing, and furniture.
Terminalia tornentosa supplies a heavy, strong, durable, and elastic wood; is, however, a difficult timber to work up, and splits freely in exposed situations; good wood for joists, beams, tie-rods, etc, and for railway purposes, and is often sold in the market under the name of sal, but it is not equal to that wood.
Thespesia populnea weight, 49 lb.; elasticity, 3294; cohesion, 18,143 lb.; strength, 7161b.; grows most rapidly from cuttings, but the trees so raised are hollow-centred, and only useful for firewood; seedling trees furnish a pale-red, strong, straight, and even-grained wood, easily worked; used for gun-stocks and furniture.
Trewia nudifiora a white, soft, but close-grained wood.
