GREENHEART , one of the most valuable of timbers, the produce of Nectandra Rodiaei, natural See also: - ORDER
- ORDER (through Fr. ordre, for earlier ordene, from Lat. ordo, ordinis, rank, service, arrangement; the ultimate source is generally taken to be the root seen in Lat. oriri, rise, arise, begin; cf. " origin ")
- ORDER, HOLY
order Lauraceae, a large See also:- TREE (0. Eng. treo, treow, cf. Dan. tree, Swed. Odd, tree, trd, timber; allied forms are found in Russ. drevo, Gr. opus, oak, and 36pv, spear, Welsh derw, Irish darog, oak, and Skr. dare, wood)
- TREE, SIR HERBERT BEERBOHM (1853- )
tree, native of tropical See also:South See also:America and the See also:West Indies. The See also:Indian name of the tree is sipiri or bibiru, and from its bark and fruits is obtained the febrifuge principle See also:bibirine. Greenheart See also:wood is of a dark-See also:green See also:colour, See also:sap wood and See also:heart wood being so much alike that they can with difficulty be distinguished from each other. The heart wood is one of the most durable of all timbers, and its value is greatly enhanced by the fact that it is See also:- PROOF (in M. Eng. preove, proeve, preve, &°c., from O. Fr . prueve, proeve, &c., mod. preuve, Late. Lat. proba, probate, to prove, to test the goodness of anything, probus, good)
proof against the ravages of many marine borers which rapidly destroy piles and other submarine structures of most other kinds of wood available for such purposes. In the Kelvingrove Museum, See also:Glasgow, there are two pieces of planking from a See also:wreck submerged during eighteen years on the west See also:coast of See also:Scotland.
The one specimen—greenheart—is merely slightly pitted on the See also:surface, the See also:body of the wood being perfectly See also:sound and untouched, while the other—See also:teak—is almost entirely eaten away. Green-heart, tested either by transverse or by tensile See also:strain, is one of the strongest of all See also:woods, and it is also exceedingly dense, its specific gravity being about 1150. It is included in the second See also:line of See also:Lloyd's See also:Register for See also:shipbuilding purposes, and it is extensively used for keelsons, beams, See also:engine-bearers and planking, &c., as well as in the See also:general See also:engineering arts, but its excessive See also:weight unfits it for many purposes for which its other properties would render it eminently suitable.
