WHALE HUNTING WITH GUN AND CAMERA 



brackish and rather impure water pumped from New York 

 Harbor, as it is not practicable to supply it with pure sea 

 water from the Aquarium's large storage reservoir, on 

 account of the fact that porpoises would rapidly discolor 

 the stored sea-water which is so important to the health 

 of the collection of marine fishes in the Aquarium. 



The necessity of keeping them in the water of the Harbor, 

 and exhibiting them in a public exhibition room which has 

 to be heated during the winter makes it, of course, impos- 

 sible to hold them under entirely favorable conditions, yet 

 they are undoubtedly doing well. They could no doubt be 

 kept for some time in fresh water, as is sometimes done with 

 seals and sea lions, but they would eventually suffer from 

 the lack of the salts contained in sea water. Porpoises, 

 perhaps of this species, frequently enter the fresh waters 

 of Pamlico Sound through the inlets southwest of Hat- 

 teras, and many species of marine porpoises make long 

 journeys into the fresh waters of rivers.
