JARRAH See also:

WOOD (an See also:adaptation of the native name Jerryhl)  , the product of a large See also:tree (See also:Eucalyptus marginata) found in See also:south-western See also:Australia, where it is said to See also:cover an See also:area of 14,000 sq. m . The trees grow straight in the See also:stem to a See also:great See also:size, and yield squared See also:timber up to 40 ft. length and 24 in. See also:diameter . The See also:wood is very hard, heavy (sp. gr. x•oio) and See also:close-grained, with a See also:mahogany-red See also:colour, and sometimes sufficient " figure " to render it suitable for See also:cabinet-makers' use . The timber possesses several useful characteristics; and great expectations were at first formed as to its value for See also:shipbuilding and See also:general constructive purposes . These expectations have not, however, been realized, and the exclusive See also:possession of the tree has not proved that source of See also:wealth to western Australia which was at one See also:time expected . Its greatest merit for shipbuilding and marine purposes is due to the fact that it resists, better than any other timber, .the attacks of the See also:Teredo navalis and other marine borers, and on See also:land it is equally exempt, in tropical countries, from the ravages of See also:white ants . When felled with the See also:sap at its lowest point and well seasoned, the wood stands exposure in the See also:air, See also:earth or See also:sea remarkably well, on which See also:account it is in See also:request for railway sleepers, See also:telegraph poles and piles in the See also:British colonies and See also:India . The wood, however, frequently shows See also:longitudinal blisters, or lacunae, filled with See also:resin, the same as may be observed in spruce See also:fir timber; and it is deficient in fibre, breaking with a See also:short fracture under comparatively moderate pressure . It has been classed at Lloyds for See also:ship-See also:building purposes in See also:line three, table A, of the registry rules .
