Rutherfurd. — On Salmonidse. 249 



possible, another attempt should be made to introduce this 

 fine fish. It is not a sporting fish, being caught trolling at a 

 great depth, but is a very valuable fish to net for market, and 

 one of the most interesting of the varieties of Salmonidce 

 found in deep lakes. 



Coregoni. 



The Coregonus albus, or whitefish, of America is a most 

 valuable fish from a table and food-supply point of view, and, 

 though no good for sport, should suit our lakes well. Seve- 

 ral successful importations of ova have been made, and it is 

 more than probable that these fish are now in Lake Eotoiti, in 

 the Nelson Provincial District. The whitefish fisheries in 

 America are large and of great value, and I think we should 

 persevere in attempts to introduce the Coregoni until a 

 planked whitefish becomes a recognised delicacy in the hos- 

 telries adjoining our magnificent lakes. Once established in 

 any lake, we could easily transport them to the other lakes 

 of the colony. 



Conclusion. 



The subjects on which I have ventured briefly to touch in 

 the short space of time at my disposal are, I think, interest- 

 ing ones, which might with advantage be enlarged upon ad 

 infinitum. 



I wish you to picture to yourselves the position of these 

 Islands, far out in the southern Pacific, with ocean surround- 

 ings differing widely from those on the British coast. Then 

 study, anai/se, and make notes on the results already ob- 

 tained from the introduction of various forms of Salmonidce 

 into entirely new environments — results which closely re- 

 semble those obtained in our sister-colony, Tasmania, and are 

 of great interest in helping to solve problems in the scientific 

 world. They seem to me to prove the truth of the theories 

 I have advanced, many of which are practically those held 

 by Dr. Francis Day, to whose works I am much indebted in 

 writing this paper. This will, I think, give us a clearer con- 

 ception of the scope of one branch of the work of acclima- 

 tisation and the far-reaching benefits we may hope to obtain 

 if we strive conscientiously to people our waters with new 

 forms of life, valuable not only from a sporting point of view 

 and as an attraction to tourists, but best suited to the wants 

 of the inhabitants of this fair land of our adoption.
