suggestion was first made that there had been but one 

 crater at Mount Gambler. 



1901 — "Notes on the Extinct Volcanoes of Mounts Gam- 

 bier and Schank" were published by Professor 

 Howchin. In these notes were suggested special 

 lines for further investigation, which the present 

 writer has endeavoured to follow. 



1906 — J. C. Moulden published a petrographical note re the 

 Mount Gambier basalt, as also had Chas. Chewings 

 in 1894. 



1907 — Dr. T. S. Hall, of Melbourne, gave some account of 

 the tuff beds, dealing more particularly with their 

 mode of deposition. 



1909 — E. II . Stanley carried out detailed chemical and 

 mineralogical examinations of the types of lava at 

 Mount Gambier, and added to these in 1910 with 

 special notes on the olivine bombs and nodules found 

 in the tuff beds. 



In addition numerous references are made to this area by 

 Professor Howchin in his Geography of South Aus- 

 tralia (1909), and in his Geology of South Australia 

 (1918).
