 75,000 were retained at tlie station, of wiiicli 25,000 were for stocking 

 the waters of the Yellowstone National Park. The inconsiderable loss 

 in hatcliing operations is ascribed to the developnu'iitof the eggs in the 

 earlier stages on gravel. Of brook trout yearlings, 7.S(M» were deliv- 

 ered for liberation in Aarious waters.

 eggs were secured, and of these only 52,(J00 survived to the age when
