334 ECONOMIC IMPOKTAN'CE OF NEMATODES. 



parasites, such as the majority of lYematodes are, it is only 

 when equipped with a detailed knowledg-e of the life aud habits 

 of a pest that we can reasonably hope to control its ravag-es or 

 effect its eradication. This entails an enormous amount of 

 study and investigation, and it is to be hoped that, when the 

 zoological survey of the Fnion is begun, one of the first g-roups 

 that will receive systematic attention will be the Nematodes, 

 the study of which group, tog-ether with the economic results 

 that are to be achieved, hold out such g^reat inducements. 



I desire to express hearty thanks to the Research Grant 

 Board for a grant-in-aid, whereby the collection of material for 

 the research on lieterodera was greatly facilitated. 



HOTTENTOT PLACE-NAMES. 



By Rev. Charles Pettman. 



Read July 17, 1920. 



There appears to be little question that the Hottentots 

 came originally from Northern Africa, and that travelling- 

 southward they were subsequently cut off from the original 

 stock by the intrusion of other nations. Driven by the pressure 

 of these nations they found their way southward and westward 

 to the coast of the sub-continent, and, following the coast, 

 ultimately reached its southernmost point. Thence, still 

 following the coast, this time eastwards, they made their way 

 nearly, if not quite, to the borders of the present Natal, where 

 they found their course blocked by the southward moving- 

 Bantu peoples. It was not until, perhaps, centuries later, that 

 in remnants of broken tribes and with no small amount of 

 mixed blood (Korannas, Griquas, Bastards), they were forced 

 back to the vast plains of the Trans-Garieb, receding this time 

 before the advance of the white men who had settled in the 

 south. 



How long before the advent of tlie Euroi)eans the 

 Hottentots had established themselves all round the coast of 

 South Africa from the Kunene on the west to the proximity of 

 Natal on the east it does not seem possible now to determine 

 with any degree of exactness. Theal (Bleek and Lloyd " Bush- 

 man Folk-lore," 1911, pp. xxviii-xxix) argues that they could 

 not have crossed the Kunene on their south-westward way 

 many centuries before the white man's arrival, and bases his 

 conclusion on 



" the fact tliat the dialects spoken by the tribes in Namaqualand 

 and beyond Algoa Bay on the south-eastern coast differed so slightly 

 that the people of one could understand the people of the other
