THE SALMON FAMILY. 6 1 



larger and more numerous, they catch them nearly 

 all, scarcely any escaping during the fishing season 

 (April I to August i). Whether an actual reduc- 

 tion in the number of fish running can be proved 

 or not, there can be no question that the present 

 rate of destruction of the salmon will deplete the 

 river before many years. A considerable number 

 of quinnat "saitnTcrrrf un in August and September, 

 and some stragglers even later ; these are all which 

 now keep up the supply of fish in the river. The 

 non-molestation of this fall run, therefore, does 

 something to atone for the almost total destruction 

 of the spring run. This, however, is insufficient. 

 A well-ordered salmon hatchery is the only means 

 by which the destruction of the salmon fisheries of 

 the Columbia River can be prevented. 



The fact that the humpback salmon runs only 

 on alternate years in Puget Sound (1875, 1877, 

 1879, etc.) is well attested and at present unex- 

 plained. Stray individuals only are taken in other 

 years. This species has a distinct run in the United 

 States in Puget Sound only, although individuals 

 (called " lost salmon ") are occasionally taken in 

 the Columbia and in the Sacramento. 



Numerous attempts have been made to introduce 

 the quinnat salmon into the waters of the Eastern 

 States and of Europe. Individuals thus planted 

 have been taken in several different localities, but 

 as yet not in any considerable number. 



The genus Salmo comprises those forms of 

 salmon and trout which have been longest known. 

 As in related genera, the mouth is large, and the 

 jaws, palatines, and tongue are armed with strong
