THURSDAY, JULY 6. 



The President delivered the following address : — 



SOME PROBLEMS PRESENTED BY THE KARROO 

 SYSTEM LN RHODESIA*. 



In considering the subject for the address that is expected 

 of me as President of this section, I am somev\diat daunted by 

 the variety of the sciences that it embraces — matters that 

 are of no little interest in a coinitry such as Rhodesia, where 

 geographers of classic renown have mapped and hunted, where 

 the rock structure has so much tu do with the distribution of 

 its metals, industries and farming, and where the complex pro- 

 blems of its ore deposits demand the continued research of the 

 metallurgist and chemist. 



Where we may have seen some apparent incongruity in the 

 grouping of the section, it becomes comi)atible if we sub-divide 

 it into two groups. In the objects of one, geographical and 

 geological research become condensed into that of a science 

 which deals with the ap])ortionment of the matter which makes 

 up the face of the earth and the distribution of the veil of 

 vegetation and its inhabitants, while in the other we attempt the 

 analysis of such matter, or the reduction of its accessory minerals 

 and ores so that they may l)e of benefit to mankind. 



At this Congress, where, besides the discussion of general 

 science, there is a desire to learn something of and consider the 

 features of the country that is being visited, it may not be sur- 

 prising if my address flavours of Rhodesia, and if I therein 

 treat, my subject as it affects, or is influenced by, this part of 

 Soutli Africa. 



A general summary of the discoveries and results of the 

 year made by workers in those sciences of which we are the 

 foster section I do not propose to attempt — partly because it 

 would be impossible to do justice to even tlie research of South 

 Africans, and also for the reason that each of the sci^ences
