part covered with the rough bark), and are found chiefly in old trees. Except 
when thoroughly dry, it furnishes but an indifferent fuel. In seasoning it 
shrinks a good deal, but warps very little. Fencing posts have been known to 
last for fifteen and twenty years, and rails for a much longer period. It is 
very liable to the attack of white ants; indeed, many trees are hollow, or 
“pipey,’ and infested with these insects. Trees growing on dry open ridges 
furnish the best timber. ; 
The bark, though inferior to stringybark, is useful for roofing and flooring 
bush buildings. When exposed, however, it does not last long, but when 
under cover it hardens and lasts a long time. 
The tree yields a kino of a ruby colour, quite transparent, and entirely 
soluble in spirit or water. It contains about 64°00 per cent. of kino-tannic 
acid. 
The Blackbutt is a tree of very rapid growth, and the leaves of the young 
saplings are opposite, sessile, and of @ lanceolate shape. Jt commences to 
flower at from about five years of age. A ship’s mast 60 feet in length and 
14: inches square has been obtained from a tree twenty-one years of age. 
Jt attains the biggest bulk of any tree in Australia, and in the sister colony 
(New South Wales) there are some giant specimens of this tree. The follow- 
ing are three of the largest :— 
1. The “ Bulli Big Tree,” situated on the Bulli Mountains, a little below 
the “ Elbow,” forty-two miles south of Sydney, said to be the largest tree in 
New South Wales. Girth, from buttress to buttress, at ground 57 feet 
Ginches; girth at 3 feet above the ground, 45 feet; girth at 6 feet above the 
ground, 40 feet; estimated height, 90 feet (the head is broken off). 
Measured March, 1891, by J. H. Maiden, Consulting Botanist, Sydney. 
2. A tree in the Illawarra district. Girth, 45 feet; height about 300 
feet. Measured by Messrs. Camara and Kirton. 
3. A tree at Gosford. Girth, 25 feet at 6 feet from the ground ; height, 
156 feet. 
Query.—Are there any giant specimens of Blackbutts in Queensland ? 
If so, can any readers furnish particulars as to girth, height, and situation ?
