joists, wheelwrights’ work, and shipbuilding purposes. It is also a useful 
building wood for general work, and is used in inside work and rough furniture, 
for implements such as mallets, and for shingles. For fencing posts it is fairly 
durable in damp localities. 
The leaves furnish but little Eucalyptus oil, and are less aromatic than- 
most other species. 
It also yields but a very small quantity of ino, or gum, of a reddish- 
brown colour, and of a gummy composition. ‘This handsome tree is generally 
much admired for its spreading limbs and its grand crown ot noble foliage, 
and is one which, for ornemental purposes, deserves a place in swampy 
localities. 
THE NARROW-LEAVED IRONBARK (HUCALYPTUS CREBRA, ¥. vy. M.). 
Boranrcat Descrrprion.—The Narrow-leaved Ironbark is a tree of variable 
size. In general it is a small or medium-sized tree, but in some favourable | 
localities it attains large dimensions. Its height varies from 60 to 100 feet, 
while its circumference ranges from 1 to 4 or 5 feet. The stem is tall and 
straight, the foliage slender and graceful, and the flower-buds, flowers, and 
fruits are quite small. 
Bark.—lIt has usually a hard, blackish, or greyish-looking, rough, persistent 
‘bark, fibrous and flaky in texture, and very deeply furrowed. 
Leaves.—The leaves are either alternate (or one above the other) or 
opposite (that is, arranged in pairs, so that one of them is immediately on the 
-opposite side of the leaf stall), linear or oblong-lanceolate (that is, long and 
narrow) in shape, straight or falcate (that is, sickle-shaped), from 4 to 6 inches 
in length, oftentimes thick, with numerous fine divergent veins. When dry 
they are often of a dull green or yellowish hue. 
Flowers.—The flowers are small, and from three to six in number, arranged 
-on short flower stalks. ‘They are of a whitish colour, and appear in bloom in 
May and June. 
Fruit.—The fruit is obovoid-truncate in shape (that is, somewhat in the 
shape of an egg), with one end terminating abruptly. It is very small, being 
less than one-sixth of an inch in diameter. They are ripe, or seed, from May 
to November. 
VERNACULAR AND Botantcat Names.—The Narrow-leaved Ironbark-tree 
(so-called from its very narrow leaves) is also known as Red Ironbark (from 
the colour of its timber). Sometimes it is called Grey [ronbark (from the 
_ colour of its bark), Pale or White Ironbark, and White Narrow-leaved Tron- 
bark. The specific name, crebra, is a Latin one, signifying standing together in 
.a crowd, and was given to this tree by Baron I’. von Muller in reference to the 
gregarious habit of the tree. 
_ Distrrzutton.—The Narrow-leaved Ironbark is found growing in patches 
or clumps in open forests, preferring ranges, ridges, and higher lands to flat or 
low-lying country, and soil of a better quality than the other species of 
Hucealypti known as Ironbarks. It is a common Queensland tree, and is found 
chiefly on the eastern slopes of the Dividing Range, both north and south, 
extending, in places, to a considerable distance inland. Its range in Australia 
extends from the neigibourhood of Jervis Bay in New South Wales to the 
- Northern Territory of South Australia. It is often found growing together 
with the Broad-leaved Ironbark (2. siderophloia, Benth.). 
Usrs.—It is a most highly valuable tree, producing an excellent timber. 
The timber is whitish-coloured near the bark, with a pinkish-grey or reddish- 
coloured heartwood. It is hard and very tough; of strongly inlocked fibre, or 
closely-grained ; and very durable. {t is useful and valuable for many building 
purposes, being closer, softer, and more easily worked than the timbers of many 
other [ronbarks. It is also heavy and elastic, and much used in the construction 
-of railway and other bridges, for piles, in wagon-building, for railway sleepers,
