428 ON A ZOOLOGICAL SURVEY, 



Such expeditions might be combined, however, with botani- 

 cal and geological surveys, provided each had their proper 

 specialists. 



Co-operation and division of labour must be arranged among 

 the different existing institutions. Each museum, for instance, 

 instead of trying to accumulate as much material as possible 

 of all classes, could confine its special attention to one or more 

 groups, and have in such a case all the available unique material 

 belonging to such a group or groups, which are now spread over 

 the whole of South Africa. I refer now, of course, not to show 

 collections, but to study collections. How much energ)' would 

 thus be saved and overlapping avoided only a systematist can 

 fully realise and appreciate, and it is surprising that such a thing 

 has not been brought about before. 



We lack a sufificient number of workers, and therefore 

 should stimulate and organise the assistance of private workers. 

 How this could be done can be discussed later on. 



The zoological survey should give facilities to institutions 

 and recognised workers to prepare monographs of the various 

 groups, such as some countries already possess. 



Connection might be established with other Governments to 

 secure assistance in identification, material and books, which are 

 not at present available in South Africa. 



I am sure that I have by no means exhausted the subject, 

 but hope to have shown, firstly, how necessary a zoological 

 survey of this country is, and secondly, in what direction its 

 activities may lie.
