identification. These fishes certainly returned to the parent 
stream, although this stream was one not at all fitted for their 
purpose. 
But this may be accounted for by the topography of the 
bay. Tomales Bay is a long and narrow channel, about twenty 
miles long and from one to five in width, isolated from other 
rivers and with but one tributary stream. Probably the 
salmon had not wandered far from it; some may not have left it 
at all. In any event, a large number certainly came back to the 
same place. 
That the salmon rarely go far away is fairly attested. Schools 
of king-salmon play in Monterey Bay, and chase the herring 
about in the channels of southeastern Alaska. A few years 
since Captain J. F. Moser, in charge of the Albatross, set gill- 
nets for salmon at various places in the sea off the Oregon and 
Washington coast, catching none except in the bays. 
Mr. Davis gives an account of the liberation of salmon in 
Chinook River, which flows into the Columbia at Baker’s Bay: 
“Tt is a small, sluggish stream and has never been fre- 
quented by Chinook salmon, although considerable numbers 
of silver and dog salmon enter it late in the fall. A few years 
ago the State established a hatchery on this stream, and since 
1898 between 1,000,000 and+2,000,000 Chinook fry have been 
turned out here annually. The fish are taken from the pound- 
nets in Baker’s Bay, towed into the river in crates and then 
liberated above the dike, which prevents their return to the 
Columbia. When ripe the salmon ascend to the hatchery, 
some two or three miles farther up the river, where they are 
spawned. 
“The superintendent of the hatchery, Mr. Hansen, informs 
me that in 1902, during November and December, quite a 
number of Chinook salmon ascended the Chinook River. About 
150 salmon of both sexes were taken in a trap located in the river 
about four miles from its mouth. At first thought it would 
appear that these were probably fish which, when fry, had been 
liberated in the river, but unfortunately there is no proof 
that this was the case. According to Mr. Hansen, the season 
of 1902 was remarkable in that the salmon ran inshore in large 
schools, a thing which they had not done before for years. It
