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 
atched 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
