46 THE AUSTRALIAN NATURALIST. 
volcanic energy to which the dykes are due. This peak, situ- 
ated some 46 miles south-east of Bondi, is about 960 fathoms 
under water and stands on an ocean floor at a depth of about 
1100 fathoms. It has been named Mount Woolnough by Mr. 
Hedley. The excursion was most enjoyable and instructive 
and Dr. Jensen’s intimate knowledge of the geological fea- 
tures of the district was freely placed at the disposal of the 
members and friends. T.S. 
EXCURSION TO BOTANY. 
Saturpay, 6TH AvGusT. 
About fifty members and friends followed Mr. 8. J. John- 
ston, B.Sc., the leader of the botanical] excursion on Saturday, 
6th August. The members caught the two o’clock tram for 
the Botany terminus and spent the afternoon collecting. The 
ordinary spring flowers were not numerous but there were 
more than sufficient for our plant hunters for one short af- 
ternoon. Mr. Johnston’s billy proved a great success and 
the afternoon proved not only a scientific success but a social 
one also. 
DUNDAS QUARRIES. 
Mr. Benson is about to publish a monograph on the geology 
of the Dundas Dyke and we look forward to the perusal of 
it with the greatest pleasure. In the account of the ex- 
cursion to Dundas Quarry in our last issue we should have 
stated that Mr. Benson is of opinion that both volcanic out- 
bursts reached the surface. 
NOTES AND COMMENTS. 
Enromotocy in South Arrica.—The outlook from an 
entomological standpoint in South Africa has undergone a 
great change since President Kruger’s time. During the 
regime of this interesting old bigot, entomological research 
fared badly, for he refused to aid in the destruction of preda- 
tory locusts on the ground that those insects had been sent 
by the Deity as a punishment for the sins of the land! To- 
day there are several State entomologists in Cape Colony and 
the Transvaal, and they are doing work of the highest eco- 
nomic value.
