Exudations. — Its bark contains large quantities of kino, which, also 

 permeates the wood. 



Mr. Forester Allan, writing to me, says : 



I obtained the gum from the ironbark by boiling the bark and straining thfr 

 liquor, aftor which I reduced it to a thick consistency. Large quantities caji 

 be obtained by this process at little cost. 



It will probably be found useful for tanning purposes. 



Size. — It attains a height' of 100' feet and a diameter of 4 feet, though 

 usually it is much smaller. Foresters Postlethwaite, of Grenfell,' and 

 Marriott, of Bubbo, both quote the height as 100 feet and the diameter as- 

 2 feet. Forester Martin, formerly of Dubbo, gave the height as 40 to OO 

 feet, and the diameter as 18 inches to 3 feet. 



Habitat. — It is confined to New, South Wales and Victoria and to tracts. 

 of country in Queensland adjoining New South Wales. In New South 

 iWales it occurs in the bush between Parramatta and Liverpool, in paddocks 

 at South Cteek, and in the neighbourhood of Richmond, and again beyond 

 the Blue Mountains, near Mudgee and Wellington, ^nd elsewhere, being- 

 widely diffused over the auriferous districts of the western and south- 

 western interior. It is rare in the southern part of the State, becoming- 

 more plentiful on the ranges near Moruya; getting more plentiful further 

 north. It is usually found on poor, sterile ranges, and is usually unaccom- 

 panied (except in the Dubbo district) by any other species of Ironbark. 



This Ironbark is commonest in the Central Division of New South Wales,, 

 and its " curving boundary " to the west (as far as I know it) is a line- 

 roughly drawn through Holbrook (near the Murray), Wagga Wagga, 

 Hillston, Nymagee, Cobar, Dubbo, Narrabri, Warialda, Inverell, and thence- 

 to the Darliiia- Downs in Queensland. I shall be glad if correspondents wilT 

 favour me with any localities west of this boundary. 



In spite of the reckless extravagance with which this timber has been cut, 

 it is by no me^ns scarce, especially in some localities, a few miles from the 

 coast. While it is a very slow-growing tree, there is some consolation in 

 the fact that it usually grows in barren, rocky country unsuitable for 

 agriculture, and therefore wholesale clearings are not made as in the case 

 with many other timbers. At the same time it does not readily reafforest. 



EXPLANATION OF PLATE 49.

B. Seedling raised from seed collected at Stuart Town, N.S.W. 

 c. Natural seedling from Oondoboliu, N.S.W. 



D. Fruits from Condobolin Hill (whence the preceding seedling was; 



obtained). Observe the warts frequently seen on the fruits of 

 this species.
