702 NARRATIVE AND ITINERARY 
The Emerald excursion included a visit to Ferntree Gully, and 
took the visitors over the interesting narrow-gauge railway through 
the hilly bush country by Belgrave and Paradise. At Warburton and 
Cement Creek also pine forests and tree-fern gullies were seen, and the 
visitors were entertained by Mr. Jas. Cuming, who afforded them 
opportunity to inspect the saw-milling and allied industries in operation 
near Warburton. 
The National Park excursion lasted from Friday night till Monday, 
the varied flora of the park and the granite and other geological features 
of Wilson’s Promontory and the adjacent mainland being inspected. 
It had been intended to reach the promontory by a Government 
steamer, but as this was required for other purposes the journey was 
made overland, and involved riding over a considerable distance. 
The excursion to the Macedon district introduced visitors to an 
area of great geological interest, on account especially of the newer 
basalt plains of Keilor and the trachytic and other volcanic features in 
the vicinity of Macedon. 
At Werribee (an excursion primarily of agricultural interest) the 
Central Research Farm was inspected, and the Members were addressed 
by Mr. Hutchinson, Minister of Agriculture, and Dr. 8. S. Cameron, 
Director of Agriculture. 
At 8 p.m. Dr. W. Rosenhain, F.R.S., delivered a Citizens’ Lecture 
in the Town Hall on ‘ The Making of a Big Gun,’ the Lord Mayor of 
Melbourne presiding. 
Sunday, August 16.—No official arrangements were made for this 
day. A considerable number of Members were away on extended

Monday, August 17.—Some sectional work occupied the forenoon. 
At 4 p.m. Professor E. B. Poulton, F.R.S., delivered in the 
Auditorium a Discourse on‘ Mimicry.’ The lecturer dealt with cryptic 
resemblance, or that form of mimicry the purpose of which is conceal- 
ment, with the sematic or advertising uses of colour, and with other 
forms of imitation, illustrating his. remarks by examples from animal, 
fish, insect, and plant life, and then went on to consider those forms of 
true mimicry where a harmless insect is protected by the resemblance 
it has acquired to some other form having distasteful qualities. The 
President presided, and a vote of thanks was proposed by Professor 
W. Baldwin Spencer, C.M.G., F.R.S., and seconded by Professor 
A. Dendy, F.R.S.
