Salmon of the Pacific Coast. Messrs, 

 David S. Jordan and Charles H. Gilbert, 

 who have been engaged in the study of the 

 fishes of the Pacific coast, state in the ab- 

 stract of their report, which is published 

 in the " American Naturalist," that they 

 have observed five species of salmon ( Onco- 

 rhyncus) in the waters of the North Pacific. 

 These species may be called the quinnat 

 or king-salmon, the blue-black salmon or 

 red-fish, the silver salmon, the dog-salmon, 

 and the hump-back salmon ; and they are 

 known by many other and vernacular names. 

 The quinnat and blue-black salmon habitu- 

 ally run in the spring, the others in the fall, 

 the two former species having the greater 

 economic value. The spring-running salm- 

 on ascend only those rivers which are fed 

 by the melting snows from the mountains, 

 and which have sufficient volume to send 

 their waters vrell out to sea, as the Sacra- 

 mento, Rogue, Klamath, Columbia, and 

 Frazer Piivers. They are chiefly adults, 

 but their milt and spawn are no more de- 

 veloped in them when they go up the rivers 

 than they are at the same time in others of 

 the same species which will not enter the 

 stx'eams until fall. High water in any of 

 these rivers in the spring is always fol- 

 lowed by an increased run of fish, and it is 

 believed that the disposition to run is ex- 

 cited by contact with cold water. The aver- 

 age weight of the quinnat in the spring is 

 twenty-two pounds in the Columbia River, 

 and about sixteen pounds in the Sacramento 

 River. Individuals weighing from forty to 

 sixty pounds are frequently found in both 

 rivers, and some as heavy as eighty pounds. 

 Fish that enter the rivers m the spring 

 continue to ascend until death or spawning 

 overtakes them. Probably none of them 

 ever return to the ocean, and a large pro- 

 portion fail to spawn. They are known to 

 ascend the Sacramento to its extreme head- 

 waters, about four hundred miles, and the 

 Columbia as far as the Spokan Falls, a dis-
