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 : 



"It 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
