514 AUSTRALIAN NATIVE PLANTS. 
N.S.W.) 6. “Red Gum.” Very wavy grain, bright red, 
twisted much in drying, full of shakes, very difficult to work; this 
timber cannot be faced with a plane, but has to be finished off 
with a scraper; diameter, 2ft. (Southern N.S.W.) 7. “ Flooded 
Gum.” Red, rather pretty wavy appearance; comparatively light 
in weight. Called “ Umbagga”’ by the blacks in Northern N.S.W. 
‘«‘Plentiful on the Clarence. This timber is extensively used for 
building purposes, such as scantling, battens, flooring boards, and 
for posts and rails, ships’ planks, etc.; it is often 7ft. in diameter, 
with a stem, without knot or flaw, of from 70 to 8oft. in length. 
Many trees yield from 6,000 to 8,oooft. of timber.” (Cat. VS. W. 
Timbers, London Exh., 1862.) 
Diameter, 6 to Sft. ; height, 1ooft.

About the Brisbane River, and in New South Wales, it is variously 
known as ‘Grey Gum,” “White Gum,” ‘ Blue Gum,” and ‘ Flooded 
Gum.” The two latter are its common names about Sydney. Other New 
South Wales names for it are ‘‘ Grey Box” and “ Silky Gum.” 
This timber is in good repute for rails for fencing and building 
purposes, as it does not readily take fire; it is also both strong 
and durable. (Hill.) It is excellent for railway sleepers. ‘ Accord- 
ing to Mr. Fawcett, the straightness of the stem renders it fit 
for spars, while Dr. Woolls calls the wood splendid, and states that 
it is largely used for ship-building ; other data pronounce it to be 
an inferior wood, and this discrepancy may be reconciled by local 
diversities of the ground, from which particular trees were 
taken.” (Mueller.) This wood is extensively used for building 
purposes, ships’ planks, naves and felloes of wheels, etc. (Woolls.) 
Mr. H. Deane informs me that what is considered to be a variety of 
this species possesses the names, at Tenterfield, New South Wales, 
of “ White,” or “Silky Gum,” on account of the satiny lustre or 
sheen of the bark. Grows well at Lucknow, India. (Gamble.) 
The following specimens of the normal species are in the 
Technological Museum: 1. “Grey Gum.” Full of shakes, very 
cross-grained, hard to work, warm brown, very heavy ; diameter,
