xlvi PROCEEDINGS OP THE GEOLOGICAL SOCIETY. [May I907,. 



in the ' Transactions of ne South African Philosophical Society,*" 

 some important papers in which striking evidence has been brought 

 forward in favour of old glaciation during more than one geological 

 period in South Africa. His volume published in London two- 

 years ago, under the title of 'An Introduction to the Geology of Cape 

 Colony,' reveals the patient and cautious character of his work, and 

 shows how firmly and quietly the foundations of our knowledge of' 

 the geological history of that interesting region are being laid. 



This Medal is always given to one who is not more than 45 years 

 of age and thus, to use the words of its venerable founder, 'probably 

 not too old for further work, and not too young to have done much/ 

 In asking you to be so good as to transmit this Award to Mr. Sogers, 

 I should be glad if you would accompany it with an expression of 

 our good wishes for himself, and of our continued interest in the 

 important and useful work of the Geological Survey which he so- 

 ably superintends. 



Mr. La3iplegh, in reply, said : — 

 Mr. President,— 



It gives me deep satisfaction to receive this Medal on behalf of 

 Mr. Pogers, for, like all the geologists who took part in the visit of 

 the British Association to South Africa, I have learned to appreciate 

 very highly the results of his work and to admire the patient 

 sincerity of the worker. 



Mr. Rogers has sent a letter which, Sir, with your permission, I 

 will read : —

' To the Cotjxcix of the Geological Society of London. 



' Gentlemen,— 



'I thank you most heartily for the honour which you have done me by the 

 award of the Bigsbj r Medal. I take it as a recognition that the geological surve}' of" 

 this Colony has been carried out on sound lines, and as an expression of your hope 

 that the work will continue. 



' The official geologists of the present generation in South Africa are more 

 fortunate than their predecessors in having instructions which allow them to work 

 steadily at the geological structure of the country, unhampered by frequent orders to^ 

 investigate some local details of passing interest. Thus a firm foundation is being- 

 laid for future work, both scientific and economic. In Cape Colony, which was the 

 first of the South African countries to institute a systematic survey, the Geological 

 Commissioners have pursued this policy from the commencement of the survey 

 under their control ; 1113' predecessor in charge of the work, Dr. G. S. Corstorphine,. 

 always kept this end in view, and I have done the same.
