2. Pittosporum bicolor, Hook.--A closely allied species, sometimes forty feet high, native of New South Wales and Tasmania. This wood is stated to be decidedly superior to the last named.
3. Bursaria spinosa, Cav.--A tree about forty feet high, native of North, South, and West Australia, Queensland, New South Wales, Victoria, and Tasmania, in which island it is known as boxwood. It has been reported upon as being equal to common or inferior box, and with further trials might be found suitable for common subjects; it has the disadvantage, however, of blunting the edges and points of the tools.
Natural Order Meliaceæ.
4. Swietenia mahagoni, L. (mahogany).--A large timber tree of Honduras, Cuba, Central America, and Mexico. It is one of the most valuable of furniture woods, but for engraving purposes it is but of little value, nevertheless it has been used for large, coarse subjects. Spanish mahogany is the kind which has been so used.
Natural Order Ilicineæ
.
Ilex opaca, L. (North American holly).--It is a widely diffused tree, the wood of which is said to closely resemble English holly, being white in color, and hard, with a fine grain, so that it is used for a great number of purposes by turners, engineers, cabinet makers, and philosophical instrument makers. For engraving purposes it is not equal to the dog-wood of America (Cornus florida); it yields, however, more readily to the graver's tools.
Natural Order Celastrineæ
.
6. Elæodendron australe, Vent.--A tree twenty to twenty-five feet high, native of Queensland and New South Wales. The wood is used in the colony for turning and cabinet work, and Mr. W.G. Smith reports that for engraving purposes it seems suitable only for rough work, as diagrams, posters, etc.
