62. Acacia Cunninghamii, Hook.—Black Wattle; Bastard Myall; 
“ Deelgar.” 
A medium-sized forest tree with often reddish branches, long sickle-shaped 
leaves; yellow flowers in spikes (July to September), and narrow, linear, 
twisted pods. The best trees are found near the coast. Yields a hard, heavy, 
close-grained, prettily marked, dark brown timber, capable of taking a good 
polish, useful for cabinet work. 
63. Acacia leptocarpa, A. Cunn. 
A small forest tree of the coastal district, with long curved leaves, yellow 
flowers in spikes, and very narrow-linear straight pods. Yields a hard, close- 
grained, prettily marked dark-brown timber. 
GROWTH OF THE LEMON-SCENTED GUM. 
TE lemon or, rather, citron-scented gum (Hucalyptus maculata) is merely 
spotted gum, differing only from the normal form in the citron-like fragrance of 
its foliage. Its native habitat, according to Mr. F. M. Bailey, Government 
Botanist, is Gladstone and Rockhampton. It is a fine large handsome tree, but 
does not succeed in Southern Queensland. Mr. C. Melton, of the Queenslander 
Office, sowed some seed, obtained from Mr. F’. M. Bailey, on the Shafton Estate 
in 1874. In fifteen years it made a diameter growth of 15 inches, and a height 
growth of over 60 feet. It was grown in shaley soil of a poor quality. In 1890 
it was blown over by a gale of wind, and in its fall along a fence carried away 
nine 9-feet panels. This would make the height of the tree about 80 feet. 
‘When the root was examined it was found that the tap-root was completely 
rotten. Another tree planted at the same time died back when it was 20 feet 
high. It was topped, then grew again, and finally died off from the same 
cause—namely, rotten roots. This shows that the tree will not prove a success 
south of Gladstone, or at least not in the neighbourhood of Brisbane. 
FOREST CULTURE, 
By GEORGE E, LOYAU. 
Tr has been rightly remarked that ‘the glory of a country is in its trees,” and 
certainly to observe the beautiful appearance they present, and how much the 
charm of the landscape is enhanced te their presence, one can but endorse this 
opinion. In some parts, however, the Australian forest has been recklessly 
destroyed ; the bushman’s axe has sounded far and wide, and an indiscriminate 
felling of trees taken place, the good and bad meeting with a like fate, whilst 
none reflected that ere many years had passed, when contracts for sleepers an! 
other large timbers for railway and other public works were in hand, 
contractors for such would have great difficulty in meeting with the supply 
necessary to fulfil their engagements, unless at ruinous prices. With suitable 
areas, and protected, this difficulty at least could be obviated, whilst the proper 
size and quality of timber would be readily obtained. 
It has invariably been found that the denuding of a country of its trees 
has been followed by sickness and epidemics more or less virulent in character; 
and instances are on record where persons living in spots which were once 
healthy suffered serious illness after the timber was cut down and removed. 
One of the most notable, and probably the best from a medicinal point of view: 
is the eucalyptus, and it is quite unreasonable to permit this valuable tree to be 
destroyed; yet, like the other trees in the bush, where its properties av¢ 
unrecognised, it invariably falls before the bushman’s axe when land has to be 
cleared. In France, its leaves have long been a notable medicine in the 
pharmacopeeia, and used the same as senna and other leaves. Wherever feve?
