scrutinised these old piles when the tide was low, and found them to be per- 

 fectly sound, uninjured by sea-worms, and having the appearance of clean, 

 well-seasoned timber, in excellent condition, notwithstanding that these piles 

 had been in sea water more than thirty-one years. 



With reference to the wharf at Port Albert, the Inspector-General of Public 

 Works, in his letter to me, already alluded to, stated that "Yellow Stringy- 

 bark and Gum are in use in the wharf and approaches to Port Albert. It is 

 reiK)rted that, whereas the Gum is fast decaying, the Stringybark remains 

 sound." My colleagues and self, after examination of the Port Albert Wharf, 

 now corroborate this statement ; the Yellow' Stringybark used in the con- 

 struction of this wharf is quite sound. 



We also inspected many old posts and rails, beams, planks, weatherboards, 

 &c., of this kind of Eucalyptus, and we all noticed that it .seemed less liable 

 to warp than any other kinds of Eucalyptus, a fact mentioned in one of my 

 previous reports on Yellow Stringybark. As. in addition to the specially 

 important quality of great durability in the sea water. Yellow Stringybark has 

 a specific strength very much greater than that of Red Gum and than that of 

 Jarrah (as shown in the tabulated results of my tests of Yellow Striugybark, 

 inserted in my report of 5th July, 1890), my colleagues and myself have 

 arrived at the conclusion that this species of Eucalyptus may be used for piles 

 and other purposes in the Melbourne harbour works. 



Size. A large tree. Trees 60 feet high, with a trunk diameter of 3 feet, 

 are not uncommon. 



Habitat. It is found in South Australia, Victoria, and New South Wales. 



In Victoria, it has an extensive range in the western half of Gippsland. 

 Lt also occurs in the Grampians and other localities nearer to South Aus- 

 tralia. 



In South Australia it is found in the Mount Lofty Range. 



It is, however, most developed in New South Wales, extending from south 

 to north, and I do not doubt that it occurs in Queensland, although it has 

 not been formally recorded from that State. 



Thus in New South Wales we have it from Twofold Bay, near Nelligen, 

 the Goulburn district, Milton, and Mount Kem'bla. 



Western localities are Kaiiimbla Valley and the Rylstone district. 



Going north, we have it 011 the Liverpool Range and eastern New England 

 as far as Tenterfield. It is very widely diffused in the northern districts and 

 presents a good deal of variation there. 



It occurs in broken country generally, preferring the taluses of the hills 

 in moderately good soil. It does not like exposed situations.

Eucalyptus acmenioides, Schauer. 

 TIIK WHITE MAHOGAXY. 



Botanical Name. Acmenioides, from two words Acme.no, and the Greek., 

 oides (like). Our common Lilly Pilly, Eugenia Smithii, was once known as 

 Acmena, and the leaves of E. acmenioides reminded Schauer of those of 

 Eugenia Smithii (Acmena).
