“SILVICULTURE IN QUEENSLAND.” 
Mr. Trist stated that the limited area of forest in 
Queensland suitable for the economic production of 
timber calls for the application of correct principles for 
marketing, protecting* and perpetuating these forests. 
The commercial forest formations of Queensland are: — 
1. The IToop Pine Rain Forest — Coastal Hardwood 
Formation. 
2. The Northern Rain Forest. 
3. The Western Cypress Pine — Hardwood Forma- 
tion. 
For each of these forest formations a silvicultural 
technique has been evolved, and this is briefly described. 
In the Hoop Pine Forest areas 17 nurseries have 
been established with capacity to provide for 3,500 acres 
of plantation yearly. 
In 1938-39 1,400 acres of plantation were pruned for 
the production of quality timber and 500 acres thinned 
for the promotion of growth. 
In the Coastal Hardwood and Cypress Pine-IIardwood 
areas, 50,000 acres were subjected to silvicultural treat- 
ment in 1938-39, making a total of 330,000 acres that 
have been so treated. 
The planting of exotics on forest country of little or 
no commercial value is also briefly described. 
A seed of the climber Macrozanonia macro car pa was 
exhibited by Miss Williamson. This seed had been 
obtained in New Guinea where the plant is comparatively 
common. The seeds have been picked up on the decks 
of schooners some distance from the land. 
EVENING MEETING, 15th April, 1940.— Mr. S. T.

visitors were present. 
A report on the Geology and Botany respectively of 
Little Yabba Creek were given by Dr. E. O. Marks and

to Birkdale were given by Mr. C. T. White (Botany) and 
Mr. N. Jack (Birds).
