through in sinking a well on the western side of Lake Torreus, 

 at a distance of about ten to eleven miles, and at an elevation 

 of about 800 feet above the sea. The well was sunk to a depth 

 of 128 feet when the borers came upon the bed rock, consisting 

 of hard red slate (gneiss form), containing glimmer. 



The following paper was read : — " On the Descriptive and 

 Economic G-eology of Munno Para East," by Mr. G-avin 

 Seoular, Corr. Meinb. (See p. 106.) 



Professor Tate thought Mr. Seoular had proved himself a 

 very careful geologist. He had reviewed the map, &c, and 

 could state that Mr. Seoular had assisted greatly in the work 

 of collecting information upon the geology of South Australia. 

 The quartzites referred to had attracted his own notice when 

 he first arrived, and he did not think such a marked feature as 

 these bands presented on the banks of the Little Para River 

 could be found elsewhere in South Australia. Mr. H. Strother 

 had been over that part of the country, and thought it a 

 remarkable piece of rock scenery — so remarkable that he con- 

 templated taking a picture of some parts for exhibition at the 

 Melbourne Exhibition. 



Professor Tate defended his view of the lacustrine origin of 

 the Upland Miocene, and contended that as the neighbouring 

 outlier at Golden Grove was bounded on the west by higher 

 land, so the contemporaneous deposits in Munno Para may 

 have been accumulated in a lake whose western margin was the 

 northerly continuation of that high land, since removed. 



A long desultory conversation ensued, and the members 

 separated at a rather late hour.
