APPENDIX. 



I am indebted to Mr. Earll for the following statistics of the 

 work of the United States Commission : 



" As the operations of the Commission have increased, and the 

 propagation 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 distributing 

 stations. The former are located near the spawning grounds of 

 those species for which they are especially intended. The eggs 

 are secured at these stations, and enough having been reserved 

 to stock the waters of that region, the remainder are sent to 

 distributing stations, usually located at some central point, 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 : 



1. Grand Lake Stream, Maine, station for collecting eggs of 



the Schoodic salmon (Salmo salar var. sebago). 



2. Bucksport, Me., station for collecting and hatching eggs of 



the Atlantic salmon (Salmo salar), and for hatching eggs 

 of the white-fish (Coregonus dupeiformis) to be distributed 

 in the waters of the State. 



3. Wood's Holl, Mass. Permanent coast station, which serves 



as a base of operations for the scientific investigations of 

 the Commission, and as a hatching station for eggs of the 

 cod (Gadus morrhua) and other sea-fishes. 



4. Cold Springs Harbour, Long Island, New York. Station 



for hatching eggs of various species of salmonidse for 

 distribution in New York and vicinity.
