ABSTRACT OF PROCEEDINGS. lix. 
18th July, 1906. 
Mr. J. HAYDON CARDEW in the Chair. 
Mr. H. D. WALSH read a paper entitled ‘“‘Timber Wharf 
Construction.’’ A review of the shipping and discharge 
arrangement in Sydney Harbour was given, together with 
the growthof wharf accommodation. The paper dealt mainly 
with timber piles and their enemies, the marine borers. 
The paper was illustrated by numerous specimens of portions 
of piles from old wharves, shewing the action of the Teredo 
navalis and marine insects. The author had also procured 
some of these marine borers and exhibited them on the 
table. 
Messrs. T. W. KEELE, P. ALLEN, J. FERRIER (Engineering 
Association), and P. W. SHAW also discussed the subject. 
August 30th and September 3rd, 1906. 
A CONVERSAZIONE in conjunction with the Engineering 
Association, the Electrical Association, and the Institute 
of Architects was held in lieu of the usual monthly meeting. 
The general idea was to have an interesting collection of 
exhibits, the special idea being to give members of the 
Section an opportunity of meeting the members of other 
Societies. 
The hall of the Royal Society was brilliantly illuminated 
by exhibits of the Hlectrical Association. Along each side 
of the hall were tables, and these together with the reading 
desk were covered with exhibits, while plans and photo- 
graphs of interesting works nearly obscured the book cases. 
The reading room and basement were also used. Considered 
only as an exhibition, it was of a nature to cause surprise 
at its variety, and the exhibits shown by each Society made 
a good show, while as a social gathering of engineers and 
architects it was more than a success.
