Following are descriptions of some logs of this species in 
the Technological Museum: 1. ‘‘Red Gum.” Very. dark red 
colour, curly and figured, looks well in cabinet-work (Victoria). 
2. “Red Gum.” Rich colour, full of shakes, difficult to work ; 
diameter, 14in. 3. ‘Red Gum.” A sound log, few gum-veins, 
rich red colour, rather curled and interlocked, hard to work, but 
after much labour produces a beautiful face;’ diameter, 20in. 
This and the preceding are from between Wagga Wagga and 
Narandera, N.S.W. 4. “ Red,” or “Flooded Gum.” Inclined ° 
to shakes; shows a pretty curly grain over its entire longitudinal 
section; dark red, very difficult to work and dress; diameter, 2ft. 
(N.S.W.) 5. ‘Flooded Gum.” Light bad colour, inclined to 
shakes and gum-veins, works fairly well; diameter, .2ft. (Eastern
