710 NARRATIVE AND ITINERARY 
entertained to luncheon by the Senate of the University. Mr. R. H- 
Roe, M.A., Vice-Chancellor, was in the chair, and the President, 
Professor Bateson, expressed the thanks of the Members. Opportunity 
was given for short excursions through Brisbane by tram-car. The 
Worshipful the Mayor held a Civic Reception in Bowen Park. 
A small party left Brisbane for Dulacca (returning on the following 
Sunday evening) to inspect the experiments being conducted there by 
Dr. Jean White for the extermination of the prickly pear. 
In the evening, at 8.30, discourses were given in the Centennial 
Hall by Professor H. E. Armstrong, F.R.S., on ‘The Materials 
of Life,’ and in the Albert Hall by Professor G. W. O. Howe on 
‘ Wireless Telegraphy.’ At the first the President was in the chair. 
Professor Armstrong discussed the part played by chemistry in the 
investigation of his subject, and showed how simpler compe nds of 
carbon, hydrogen, oxygen and nitrogen were built up into the more 
complicated substances found in the plant; he then traced the breaking 
up of these in digestion and the further formation from simpler sub- 
stances of the more complex materials of the animal’s body. Professor 
B. D. Steele proposed a vote of thanks. : 
Sir Oliver Lodge, F.R.S., presided at the discourse by Professor 
Howe, who, after explaining the principles of the subject, traced their 
practical application in the development of the various systems of wire- 
less telegraphy. A number of lantern slides were shown, illustrating 
the construction of modern high-power stations. Sir A. Cowley pro- 
posed, and Professor Luigi Luiggi seconded, a vote of thanks to the 
lecturer. 
Salurday, August 29, was devoted to excursions. Opportunity was 
afforded for visits to the Ipswich railway workshops and the vicinity 
of the town; to Nambour and the Blackall Range (an excursion 
arranged for and taken advantage of by a large party, amounting to 
some two-thirds of the visiting Members); to the Glass House Moun- 
tains, to visit which a small party left the special train to Nambour and 
proceeded on foot to the summit of Mount Ngun Ngun and to the 
bottom of the cliffs on Mount Crookneck, rejoining the special train on 
its return; through the Cleveland district, south of the Brisbane River, 
and to Mount Coot-tha, a view-point within the metropolitan area. 
At Nambour the Moreton Central Sugar Mill was inspected, and at 
luncheon the visitors were welcomed by the Mayor of Nambour and 
the Maroochy Shire Council. The Range and the Maroochy river were 
subsequently visited, and tea was served on the return to Nambour. 
A longer excursion undertaken by some of the Members was that to 
Gympie Goldfield, the party being the guests of the Corporation of 
Gympie, and returning to Brisbane on Sunday morning. 
Sunday, August 30.—As elsewhere, no official arrangements were 
made for the Sunday. At night, however, a few members left for 
Mount Morgan Gold and Copper Mine (420 miles from Brisbane), an 
excursion which lasted until Thursday morning, September 3. 
Monday, August 31.—In the morning an excursion was made by 
steamer down the Brisbane River to the meat-works situated thereon.
