THE ATLANTIC SALMON 175 



Atlantic coast, but always without good for- 

 tune, apparently because its natural spawn- 

 ing-grounds are in a mucb higher latitude than 

 Maine. 



Attempts were also made to introduce the 

 silversides, a fish that spawns in about the same 

 latitude as the Atlantic salmon; the young 

 thrived in the hatching-ponds at East Orland, 

 Maine, and in the state breeding-ponds in Penn- 

 sylvania, to within one year of breeding age, 

 when the experiment was abandoned. Fish a 

 year old had attained an average length of 

 seven or eight inches; they fed greedily and 

 maintained vigorous health. That initial 

 plantings in the tributaries of the Delaware 

 Eiver were successful is evinced by the fact that 

 in July, 1908, three young silversides were 

 caught in the Lackawaxen Creek, Wayne 

 County, Pa. 



Eepeated but unsuccessful attempts have 

 been made at the United States hatchery of 

 East Orland, Maine, and at the "Wayne and 

 Bellefonte hatcheries in Pennsylvania, to do- 

 mesticate Atlantic salmon in numbers sufficient 

 to establish breeding-ponds. Mr. Atkins, Su-
