2/O SCIENCE SKETCHES. 



From this, in 1792, the old German compiler 

 Johann Julius Walbaum gave them their scientific 

 name of Salmo mykiss, and to this day and for- 

 ever Salmo mykiss 1 is the scientific name of the 

 Cut-throat Trout. 



Finding Alaska a good " fishing-ground," the 

 trout spread itself through all its rivers. The 

 conditions of cold clear water from the mountains 

 to the sea are much the same all the way from 

 the Yukon to Fraser's River and the Columbia and 

 even as far south as the Umpqua and the Klamath. 

 To all these, one after another, the Cut-throat 

 Trout came from the North. The ocean offering 

 easy access from the mouth of one to the mouth 

 of another, there is very little difference to this 

 day among the colonies inhabiting the different 

 river basins. The Mad River and Elk River in 

 Humboldt County, California, mark the southern- 

 limit of the extension of the Cut-throat Trout 

 along the west coast by processes of ordinary 

 transfer from river to river by way of the sea.

1 By the laws of scientific nomenclature, the oldest name of any 

 species is its right name, all questions of which name is the best 

 or sounds the best being disregarded. The Cut-throat Trout 

 was called Salmo mykiss in Kamchatka by Walbaum in 1792, 

 Salmo muikisi by Schneider in 1801, Salmo furpurattis by Pallas 

 in 1811 ; these specimens being all of the Mykiss of Kamchatka. 

 It was named Salmo clarkii by Richardson in 1836, from Columbia 

 River specimens. A number of other names, as Salmo stellatus, 

 brevicauda, and aurora, were applied by Dr. Charles Girard to 

 specimens brought in by the Pacific Railroad Survey. 



2 The Cut-throat Trout of the Lower Columbia and of Puget 

 Sound cannot be distinguished from that found in Alaska. It is, 

 however, sometimes given a separate name in science, as Salmo 

 mykiss clarkii.
