It is employed in ship-building,and forms one of the best materials for treenails, and for workinginto large screws. It is pale, strong, hard, of close and interlockedgrain, and not fissile. It is useful for such articles as mauls andhandles, which need toughness of wood for their manufacture. Th ,G OO fen oo > Q <u C^ ?^ < T3 O G ^ co CQ OT Z; G C 1—1 rl o > a.

It is subject to destruction by white ants and dry rot when standing-long in the ground. Mr. Allen Ransome tested a sample of this wood sent fromVictoria to the Colonial and Indian Exhibition. During thetrials a sleeper was adzed and bored ; but for boring especially,the wood seems very hard. A panel was also passed through theplaning-machine, but, owing to the sample being very cross-grained, the results were not good. The Rev. Dr. Woolls points out that this species is indicativeof good grazing country. I have assumed that the Box timber tested by CaptainWard (Sydney Mint Experiments, 1858) belongs to this came from Singleton. Specific gravity, ; value of E,538,800; of S, 2,445. A specimen called White Box, or * Grey Box, fromVictoria, in the Museum, is hard and tough, of very close grain,,and of a brown colour. A sample of timber (No. 10, LondonExhibition of 1862, and No. 102, Paris Exhibition of 1855) is inthis Museum, and very probablusefulnati
