i8 2 MARVELS OF FISH LIFE 



soon the bottom of the bottle contains thousands of? 

 cyelops, daphnia, water-beetles, spiders, etc. The 

 contents of this bottle are then emptied into the } 

 tubs. 



These minute creatures multiply so rapidly that in 

 a week or two the water in all the tubs is seething with 

 life. When wanted for fish food, these crustaceans are 

 collected in a similar manner from the tubs, the water 

 that passes through the bottle being allowed to run 

 back into the tubs. 



While on a fish photographic excursion the photo- 

 grapher will have the time and opportunity to procure 

 his own specimens, but should he not be a sufficiently 

 expert fisherman to do this for himself, it is always 

 possible to get specimens from other anglers, or from 

 the professional fisherman, provided he is willing to 

 carry them home in a can. If, however, he should ask 

 a fisherman to get the specimens, he should be sure to 

 mention the largest number of fish that he desires to be 

 put in the can, for the fisherman, as a rule, stuffs the can 

 so full that frequently the specimens are all dead before 

 they reach you. I well remember lending a large can 

 to a shrimp trawler in order to procure a number of 

 small flat fish. It came back two-thirds fish and one- 

 third water, there being some three hundred specimens 

 in all, and not a living fish among them ! 



The procuring of specimens for photography at 

 home is a much more difficult matter. My living fish 

 have been obtained in various ways.
