is possible that the fish, being forced in close to the shore, came 

 in contact with the current from the Chinook River, which, 

 since the stream is small and sluggish, would not be felt far from 

 shore. Once brought under the influence of the current from 

 the river, the salmon would naturally ascend that stream, 

 whether they had been hatched there or not. " 



The general conclusion, apparently warranted by the facts 

 at hand, is that salmon, for the most part, do not go to a great 

 distance from the stream in which they are hatched, that most 

 of them return to the streams of the same region, a majority to 

 the parent stream, but that there is no evidence that they choose 

 the parental spawning grounds in preference to any other, and 

 none that they will prefer an undesirable stream to a favorable 

 one for the reason that they happen to have been hatched in 

 the former. 



The Jadgeska Hatchery. Mr. John C. Callbreath of Wrangel, 

 Alaska, has long conducted a very interesting but very costly 

 experiment in this line. About 1890 he established himself 

 in a small stream called Jadgeska on the west coast of Etolin 

 Island, tributary to McHenry Inlet, Clarence Straits. This 

 stream led from a lake, and in it a few thousand red salmon 

 spawned, besides multitudes of silver salmon, dog-salmon, and 

 humpback salmon. Making a dam across the stream, he helped 

 the red salmon over it, destroying all of the inferior kinds which 

 entered the stream. He also established a hatchery for the 

 red salmon, turning loose many fry yearly for ten or twelve 

 years. This waS done in the expectation that all the salmon 

 hatched would return to Jadgeska in about four years. By 

 destroying all individuals of other species attempting to run, it 

 was expected that they would become extinct so far as the 

 stream is concerned. 



The result of this experiment has been disappointment. 

 After twelve years or more there has been no increase of red 

 salmon in the stream, and no decrease of humpbacks and other 

 humbler forms of salmon. Mr. Callbreath draws the con- 

 clusion that salmon run at a much greater age than has been 

 supposed at the age of sixteen years, perhaps, instead of four. 

 A far more probable conclusion is that his salmon have joined 

 other bands bound for more suitable streams. It is indeed
