of appetite, lassitude and a temperature of from 103 to 105 

 the only remedy is to inoculate at once with Tripan-blue, a supply 

 of which should be carried. The disease leaves the heart very weak 

 and careful nursing is required during convalescence. If an abscess 

 forms as a result of the inoculation this has to be lanced. 



9. MAPS. 



Though a considerable part of the territories dealt with is covered 

 by primary and secondary triangulation, they are on the whole 

 y poorly off in the matter of accurate large-scale maps and 

 particularly in the matter of topographical maps. It is generally 

 the case, however, that the material avaiable is not fully utilised. 

 The traveller is therefore recommended to get into touch with the 

 Surveyor General of the particular province in which his work lies 

 in order to find out exactly what has been done in regard to the 

 area te be examined. 



It this way it is often possible to obtain tracings or blue-prints 

 of unpublished maps which are of the greatest assistance. 



Maps are best carried in water tight galvanised iron map cases 

 provided with a good padlock. 



For information in regard to magnetic declination, etc., Professor 

 J. C. Beattie's "Report on the Magnetic Survey of South Africa", 

 published by the Royal Society, should be consulted. 



10. INTERCOURSE WITH NATIVES. 



The success or otherwise of an expedition will be found in no 

 small measure to depend upon the traveller's ability to get on 

 with his own natives and those with whom he may happen to come 

 into contact. It is not merely a question of tact but of studying 

 the workings of the native mind and allowing as far as possible 

 for its idiosyncrasies. Only in this way can he hope to win their 

 confidence and whole-hearted service. 



It should be remembered above all things that the native of 

 South and East Africa: 

 a. baa a keen - almost an exaggerated - - sense of justice; a 



promise once made, however trivial it may appear, should, 



therefore, always scrupulously be observed; 

 />. is an excellent judge of character and invariably respectful to 



those who command respect among their white subordinates, 



but inclined to take liberties with those who do not;
