The oils of “Bangalay” (E. botryoides) (saligna, var. botryoides) ; “Fuzzy 
Box” ( Baueriana , var. conica) ; “ White Gums” (Gunnii, var. maculosa and var. 
rubida) ; a Mallee [M orris ii) ; “Swamp Box” ( bicolor) ; “Box” {quadranyulata) ; 
“ Fat Cake Ironbark ” (sideroxylon), and other species contain similar constituents. 
Flowers. —Flowers from August to September, and the flowers are much 
sought after by bees. (Forester John Martin, late of Gosford.) 
Hark.—The bark (often of a “corrugated” appearance) is sub-fibrous, of 
loose, and even woolly, texture. In colour it is of a sort of brick or rusty red, and is 
persistent even to the smallest branches. 
“It has a corrugated, somewhat fibrous or stringy bark which is always 
riddled with the ‘roads’ of white ants into within J of an inch of the sapwood.” 
(Forester W. P. Pope, late of Murwillumbah.) 
Timber ,—Its colour is usually yellowish-brown or yellowish (sometimes, e.y., 
at Camden Haven, much of the timber has a pink tinge), and like many other 
timbers darkens with age. One of the least liable to shrink of all our hardwoods. 
It is heavy, strong, and durable. It may be planed and turned with great satisfac¬ 
tion. It is not easily split, the greasy substance contained in it making it a tedious 
matter to get the wedge to “draw.” I would express the opinion that, after Iron- 
bark, Tallow-wood is the most valuable of our hardwoods. 
It is used for flooring, particularly in ball-rooms. For this latter purpose it 
is selected on account of its greasy nature. It is excellent for decking, handrailing, 
girders, and some other parts of bridges. A favourite for building work generally, 
and it does not burn readily, which, in buildings, is, of course, a recommendation. 
It is, perhaps, the most valuable wood in New South Wales for paving blocks. It 
makes admirable posts and rails, lasting an indefinite period either above or below 
ground, but difficult to split for these purposes, as already remarked. White 
Mahogany is not infrequently substituted for Tallow-wood. Both are good timbers, 
and can stand on their own merits. The substitution can be readily detec led bv any 
man with a fair knowledge of colonial timbers.
