POPULAR MISCELLANY.

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 abstract of their report, which is published in the "American Naturalist," that they have observed five species of salmon (Oncorhyncus) 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 habitually run in the spring, the others in the fall, the two former species having the greater economic value. The spring-running salmon ascend only those rivers which are fed by the melting snows from the mountains, and which have sufficient volume to send their waters well out to sea, as the Sacramento, Rogue, Klamath, Columbia, and Frazer Rivers. They are chiefly adults, but their milt and spawn are no more developed 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 streams until fall. High water in any of these rivers in the spring is always followed by an increased run of fish, and it is believed that the disposition to run is excited by contact with cold water. The average 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 proportion 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-
