of the life history of the crawfish and possible practical results 

 of great economic importance. Steps should at an early date 

 he taken in the matter of artificial hatching. In the emphatic 

 words of the manager of the Hout Bay Factory " the sooner 

 such a course is adopted the better ; it is inadvisable to follow 

 the example set in the Northern Hemisphere and wait until the 

 fishing grounds are denuded before making the experiment." 



Finally, the question of controling crawfish factories and the 

 procuring of reliable returns of quantities and conditions of fish 

 caught should receive careful consideration, and adequate 

 means should be taken for inspection. 



Xoic. — In carrying out these investigations on the Crawfish 

 and Crawfish Industry I have been greatly assisted bv the ready 

 co-operation of the Managers of the Crawfish Factories, tcj 

 whom 1 desire to express my obligations. The actual fishuig 

 operations mentioned on p. 5 were efficiently carried out by 

 the Fishery Officer, Mr. Cripps.
