Hickory (Acacia spp.). 
Under this name several local species of Acacia are used in various parts of the State. 
The wood is evidently fancied for particular parts of coachbuilding, or it would not be used. 
I should say that they are most probably those that have a hard, dark wood, and are preferred for 
their durability. 
Yarran (Acacia homalophylla, A. Cunn.). 
Wherever this tree is found growing in the State, I have been informed that it is used by 
coachbuilders. 
The timber is dark coloured, very hard, and heavy, yet not difficult to dress ; and for certain parts 
of a vehicle should be most durable. 
Gidgee (Acacia Cambagei, R.T.B.). 
This timber, I have been given to understand, is used, wherever the tree is found, for parts of ‘ 
coachbuilding. It is similar in texture and qualities to Myall and Yarran. 
It is a very hard, dark, cross-grained timber, but difficult to dress. It is much in request for 
stockwhip handles. 
Teak (Flindersia australis , R.Br.). 
One of the finest trees of the Northern Rivers scrubs, and is fast being cut out, as large quantities 
are exported to Europe. 
The timber is yellowish, pale-coloured, hard, close-grained, and fairly easy to work. 
Tt is very durable in railway rolling-stock, and a sample is exhibited in the Technological Museum, 
which has been in use for twenty years ; a supporting column in a goods waggon on the New South Wales 
Railways is as sound as the day it was put in. No better proof can be given of a timber’s qualities 
than this. 
It is quite a different timber from the Burma Teak, which is brownish in colour, and more open 
in texture. 
Blackbutt (Eucalyptus pilularis, Sm.). 
A large forest tree, with a light-coloured timber; straight-grained, hard, strong, and very durable. 
Useful for wheelwrights and coachbuilding, and, in fact, a good all-round timber. It must be durable for 
goods waggons, as a specimen of a sole bar is exhibited in this Museum which was taken thirty years ago 
from a goods truck, and has still some life in it. 
Flooded Gum (Eucalyptus saligna, var. pallidivalvis , R.T.B. et H.G.S.). 
A light, red-coloured, straight-grained, free-working timber, often substituted for Blue Gum 
(E. saligna), which it somewhat resembles. Its durability and uses are many, and it should be a good 
timber for felloes, spokes, naves, and in lighter work. 
Ironbarks. 
Under this name are used indiscriminately three kinds : — 
Narrow-leaved Ironbark (Eucalyptus crebra, F.v.M.). 
Grey or White Ironbark (E. paniculala, Sm.). 
Broad leaved Ironbark (E. siderophloia, Benth.). 
These differ from each other, more particularly in colour ; they are all very hard, close-grained, and 
most durable. Of the three, the Broad-leaved is least furrowed in some parts, as it is, perhaps, not so 
durable as the others. 
Ironbark is the timber mostly used for naves, heavy spokes, shafts, poles, <fec., and its qualities are 
too well known and familiar to my audience to need comment here.
