478 AUSTRALIAN NATIVE PLANTS. 
South Wales. A Victorian specimen in the Museum is figured in 
stripes of a yellow and brown colour, and is close-grained, 
I do not doubt that the following specimens (also in the 
Museum) belong to this species :-— 
No. 48 (Lond., 1862); 124 (Paris, 1855), Camden ‘‘ Stringy- 
bark;” called ‘ Bour-rougne’’ by the Camden aboriginals. Dia- 
meter, 24 to 54in.; height, 50 to rooft. “A species yielding 
timber much prized for flooring-boards and house-carpentry, of 
considerable strength and durability; differs from the stringybark 
of the coast.” One sample is of a light-brown colour, and of a 
tough nature. It tears up a good deal under the plane. The 
second sample appears in no way altered or different to the first. 
It is part of a post placed in the ground in 1815, and dug up in 
1861; certified to by the late Sir William Macarthur. 
Some specimens of this timber were tested by Mr. F. A. 
Campbell (Proc. R.S., Victoria, 1879) for tensile strength. His 
figures (lbs. per square in.) are 23,000, 23,400, and 20,000, An 
inferior piece broke at 11,700. The specimens broke with a very 
long fracture. 
It is probable that the ‘“‘Stringybark’’ timber tested by 
Captain Ward (Sydney Mint experiments, 1858) belongs to this 
species. It came from Singleton, New South Wales. Specific 
gravity, .937; value of E, 343900; of S, 1818.
