bring the fish into life at such a time as their natural 

 food shall he furnished through natural causes ? 



In proof of this theory being practical, allow me 

 to refer you to the experiment made by me last win- 

 ter at my hatchery at Clarkston, of which our State 

 Fish Commissioners and many other distinguished 

 citizens were cognizant. 



After keeping several thousand of the white fish 

 ova about two weeks in ice-water, I removed them 

 to a refrigerator, so arranged as to admit alternate 

 layers, first of moss, and then thin muslin cloth, next 

 the ova, thin muslin cloth again, which was followed 

 by a layer of ice, supported by galvanized iron. 



This arrangement can be repeated ad infinitum 

 By this means the eggs were kept at a temperature 

 just above freezing, which delayed their incubation 

 to the time I desired to remove them to the hatch- 

 ing-trough. 



When hatched out they must, of course, lie in 

 the natural element to escape death. 



Some time in the month of March, these eees 

 were taken from the cold bath in which they had 

 lain nearly four months in a perfectly healthy con- 

 dition, and were all hatched within six days after. 

 Their conditions were thus changed ; this being 

 true, I would ask, why may not the salmon ova be 

 taken from the McCloud river, California, and be 

 similarly treated, and removed to almost any part 

 of the globe, successfully ? 



But to return to the fish of which we were speak-
