"A tree 100 to 150 feet high with diameter 4 to 5 feet; native of tlie tropical coast 

 regiona of New South Wales and (Queensland. Valuable timber tree, esi)ecially for 

 posts and underground situations; also for piles, as the resinous matter contnined xn 

 the wood makes it resistant to damp, the attacks of white ants, and the Teredo. 

 Entirely unprotected piles exposed to the waves for twelve years were found abso- 

 lutely free from decay and the attacks of the Teredo. The wood is also ditlicult and 

 slow to l)urn, a useful property in building lumber. An oleo-resin, in degree and 

 character something between "Venice turpentine and Canada balsam, contained in 

 the wood is best collected by felling the tree, when it exudes between the bark and 

 sapwood in small drops, which mav be scraped off and the resin collected in a pure 

 state." (./. Jf. Maiden.)
