TIMBERS. 525 
This tree has succeeded admirably at- Abbottabad, Punjab, 
India. (Gamble.) Timber of this species is well represented in 
the Technological Museum. Following are specimens (all from 
N.S.W.): 1. “Slaty,” or “Blue Gum.” Light reddish-brown, 
easy to dress, has seasoned only fairly well; diameter, gin. 
(Tomerong, near Shoalhaven.) 2. ‘“Slaty,” or “Blue Gum.” 
Dark red, very few gum-veins, heavy, medium to work ; diameter, 
18in. (Myall River, near Shoalhaven.) 3. “Grey Gum.” Dark 
red, very heavy wood, full of gum-veins, difficult to season, 
very difficult to work; diameter, 15in. (Port Hacking.) 4. ‘ Blue,” 
or “Grey Gum.” Fairly sound log, slight shakes; colour, reddish- 
brown; diameter, 20in. (Clarence and Richmond.) 5. This 
is the species referred .to by Sir William Macarthur in his 
Catalogue of Woods at the Paris Exhibition, 1855 (No. g2), and the 
London Exhibition of 1862 (No. 19), as the ‘‘Blue Gum of 
Camden.” In the catalogues of both exhibitions the native name 
in the Illawarra is given at ‘‘Tdjetlat,” or ‘‘ Tjellat,’ and also 
“‘ Barroul-goura,” while in the latter catalogue the name is given as 
*“Yarrah” at Camden. ‘A very valuable timber, harder, tougher, 
more inlocked in grain, and more durable than the last (which is 
E. botryotdes, vide supra), but not obtainable of nearly such large 
size; one of the most durable woods known; excellent for naves 
and felloes of wheels, and for work underground.” (1855, 
Cat.) Diameter, 3 to 4ft.; height, 80 to rooft. It is of a 
dark red colour, wavy, has quite a sheen, and has stripes on 
the end grain. It is hard and inlocked in the grain, but 
works remarkably well. A sample of this timber was ex- 
perimented upon by Captain Fowke, R.E. (Paris, 1855). He 
found the specific gravity to be .843 (or weight of cubic foot, 
52.54lb.), and S, 224. Eis not given. 6. No. 20, London Exh., 
1862; 924, Paris Exh., 1855. ‘Blue Gum,” from Appin. 
“Timber of excellent quality.” Diameter, 36 to 48in.; height, 
80 to rooft. Of a reddish-brown colour, heavy, very cross-grained, 
but of excellent quality. It works freer than No. 5, and is freer 
from grub-holes, otherwise they are much the same. 7. No. 21, 
London Exh., 1862. Same name and locality as No. 6. Of a 
dark red colour, with cross, curly grain; a heavy timber,
