opposition, the Club, by advocating the reservation, 

 would materially strengthen his case. He would therefore 

 move — " That the Fisheries and Game Department be written 

 to and asked to proclaim that part of the country a sanctuary 

 for native game." 



In seconding the resolution, Mr. O'Donoghue said the 

 Chief Inspector of Fisheries and (iame was aware of, and 

 had repeatedly tried to prevent, punt-gun shooting on Mourn 

 Pool. He had been informed that, after a single discharge of 

 the gun used by one individual, as many as 72 pairs of ducks 

 *had been picked up. Some idea of the number of water- 

 fowl congregated in the locality might be realized when, in 

 one small area of water, it was' estimated that there were at 

 least three thousand black duck and teal, besides other 

 aquatic birds. 



The motion, on being put to the meeting, was carried 

 unanimously. 



REMARKS ON EXHIBITS. 



Mr. G. A. Keartland drew attention to his exhibit of a 

 caged Blood-stained Cockatoo, Cacatua sanguinea, Gld., from 

 Broken Hill. When he purchased the bird, which was 

 now 15 years old, it was quite young, and the naked 

 skin round the eyes was white. Since then the skin has 

 changed to a blue colour, which is the chief characteristic 

 feature that differentiates C. gymnopis from C. sanguinea. 

 If both species were good ones, to which did the bird ex- 

 hibited belong? 



Dr. T. S. Hall, in referring to his exhibit of a tibia of the 

 Great Red Kangaroo, Macropus rufus. said the specimen 

 was 22f inches long, and that there was a specimen in the 

 National Museum about half an inch shorter. These, he con- 

 sidered, mu.st almost be record lengths. The specimen under 

 notice in all probability came from Western Australia. 



Mr. A. L. Scott handed in a note referring to his exhibit 

 of iron and lime concretions, collected during the excursion 

 to Beaumaris on Saturday, T2th December, stating that the 

 formation of these concretions is not altogether understood. 

 In a genera] way it is known that water percolating through 

 soil and surface rock is practically always a carrier of organic 

 acids. These acids may attack both the iron and lime con- 

 tents of the rock. Changes in temperature, pressure, and 

 contents of the water act and react on each other. Thus we 

 find minerals being dissolved out in one place only to be 

 carried away for re-deposition in another, usually in a dif- 

 ferent form. The lime in the shells lliroughout the Beau- 

 maris cliflfs has been, and is still being, dissolved out, only 

 to be re-deposited as nodules, which in turn are waslied out
