Mr. F. B. Guthrie has given in the Agricultural Gazette the following 
analysis of leaves :— 
Water ... ... .. ... ... ... 41-70 
Ash. 3-42 
Fibre.11-43 
Ether extract (oil, etc.) ... ... ... ... 3-92 
Albumenoids ... ... ... ... ... . 9 - 31 
Carbo-hydrates ... ... ... ... ... 30-22 
Nutrient value ... ... ... ... ... 48| 
Albuminoid ratio ... ... ... ... ... 1 : 4 f 
Tannin (Oak bark) .. ... ... ... ... 2-9 
The young leaves are very aromatic, and the oil-dots may he plainly seen, 
showing the affinity to Rutacece as already pointed out by Engler. 
Fruit. —The fruit when quite ripe tends to be flat like a five-pointed star. 
It is reddish brown externally. The fruit depicted is just opening to shed its winged 
seeds. 
Bark. —Its characteristic appearance has already been alluded to. 
Timber. —This is a small tree, and not important as a timber. At the same 
time it is used to a small extent. The timber is used for shingles, staves of tallow 
casks, and pick-handles.—(Hill). It is of a bright yellow colour when fresh, and 
exceedingly tough. Unlike many other timbers in the arid western districts of 
New South Wales it is very elastic, and is, therefore, used for the poles and shafts 
of drays, buggies, etc. A writer says, “ It is white and very light, and is used by 
the blacks for making their ‘heilamans’ or shields. For all other purposes it is utterly 
worthless.” Others say, “No good except for bullock-yokes.” I saw it made into 
tool-handles at Bourkc. In the rough state ( i.e ., with the bark on) it is used for 
fencing, but it is useless for building purposes, as a coleopterous insect soon destroys 
it. About Wilcannia, N.S.W., it is, however, considered very durable by some, when 
sawn and used for inside work. 
Exudation. —This is probably the tree referred to by Mitchell, in the 
following passage :— 
In the ground beyond the plains (near the Darling) .... and an Acacia, with a white 
stem, and spotted bark, there grows to a considerable size, and produces much gum. Indeed, gum acacia 
abounds in these scrubs, and when the country is more accessible, may become an article of commerce. 
—(Three Expeditions, i. 203.) 
For an account of the gum arabic from this tree, one of our best soluble 
gums, see the following paper. * Dr. Lauterer also gives an analysis of this gum. 
During the summer months large masses, of a clear amber colour, exude from the stem and 
branches. It makes good adhesive mucilage, has a splendid taste, and is eaten by the aborigines. It is 
commonly used by bushmen as a remedy in diarrhoea.
