which it is supposed to resemble ; hut the name is not a happy one. “ Black Sally” 
is undoubtedly its commonest name, this and “ Black Gum ” being given owing to 
the rough, hard, dark bark on the butt. Leichhardt called it “ Olive-green Gum ” ; 
Macarthur “ Green Gum ” and “ Lead Gum.” The last three names are attempts 
to describe the appearance of the smooth portion of the bark, which varies from 
white with a bluish or lead-coloured cast to even an olive-green. It is called 
“ Muzzlewood ” in Gippsland and southern New South Wales, because it is some¬ 
times used to make muzzles for sucking calves.

Bark. —This is a gum or smooth-barked Eucalypt. It has more or less 
rough bark towards the butt, which in mature trees is hard, rough, and black; in 
smaller and younger trees more or less ribbony. The upper or smooth portion of 
the trunk has been alluded to under “Vernacular Names.” 
Timber. —Pale-coloured, rarely free from gum-veins ; warps seriously ; a 
sound log of any size very rare; of little value for purposes other than fuel. Timber 
that shrinks much in drying may do so regularly or irregularly. Those of the first 
class have, when dry, practically the same shape as the original piece; but those of 
the second class take on an irregular shape. The timbers of E. stellulcitci and 
E. coriacea belong to the latter class. 
Exudation. —The kino is ruby-red, and, when fresh, readily soluble in cither 
water or alcohol. It is, in consequence, a member of my ruby group of kinos, and 
may be used medicinally as a simple astringent. 
Size. —It is a forest tree of medium size in the Monaro, e.g., in the Snowy 
liiver Valley, forming a shapely tree 50 feet in height and more, with a stem- 
diameter of 2 to 3 feet, and with a dense foliage. In New England it attains a 
scarcely less size. As a rule, it is a straggling tree of half the size, while the narrow¬ 
leaved variety is frequently only a tall bush.
