UNITED STATES FISH COMMISSION. 



Hatching-Stations* As the operations of the 

 commission have increased, and the propaga- 

 tion of additional species has been undertaken, 

 it has been found desirable to increase the 

 number of hatching-stations. These are of 

 two kinds, known as collecting and distribut- 

 ing stations. The former are near the spawn- 

 ing-grounds of those species for which they are 

 especially intended. The eggs are secured at 

 these stations, and enough having been re- 

 served to stock the waters of that region, the 

 remainder are sent to distributing stations, to 

 be hatched and shipped to the waters for which 

 they are intended. The following is a list of 

 the hatching-stations operated by the United 

 States Fish Commission in 1883, for which we 

 are indebted to R. Edward Earll : 



1. Grand Lake Stream, Me., station for collecting 

 eggs of the Schoodic salmon (Salmo salar, subsp. se- 

 bago).
