AND OF STILL WATERS. 



water in which the fish live, who no doubt give 

 the new arrivals a warm welcome. One of the 

 greatest difficulties of coarse-fish breeding is 

 that of feeding the young fry. Mr. R. B. Mar- 

 ston explains this difficulty in a very simple 

 manner. 



"The umbilical sac," he says, "on the contents of 

 which the trout alevin exists for six weeks, lasts the 

 alevin of the coarse fish but a day or two, and unless the 

 young fish are fed they will die, hence the difficulty of 

 rearing them in confinement. Dr. Kelson, of Oxford, 

 last year made the valuable discovery that the animal- 

 cule bred in water containing decayed vegetable matter 

 (like that in which cut flowers have been kept some time) 

 are eagerly devoured by the young fry. I think it is 

 difficult to overrate the value of this discovery to the 

 breeder of coarse fish." 



But it should be borne in mind that Herr 

 Fruwirth's system has the great merit of sim- 

 plifying fry-feeding by supplying natural food in 

 large quantities. 



In many ways the artificial cultivation of 

 salmon and trout is far easier than that of coarse 

 fish. Not only is the feeding of the fry of the 

 Salmonidce in its early stages of existence better
