OREGON BROOK TROUT. 



In Oregon and Washington there is a trout which is scarcely dis- 

 tinguishable from the Rainbow trout. It reaches, however, so far as 

 we know, only a small size. We have seen none weighing a pound. 

 The mouth is smaller than any other of our trout, and the dorsal fin 

 is less spotted than in the true Rainbow. 



This dainty and gamy little trout was first taken in the Cathlapootl 

 River by General George B. McClellan. Dr. Suckley named it Solum 

 masoni.

KERN RIVER TROl.'T. 



Iii the Kern. Bangs, Merced and other rivers of the southern portion 

 of the Sierra Nevadas the Rainbow trout have much smaller scales than 

 in the coastwise streams. About one hundred and sixty-five scales 

 form lengthwise series. Unlike the true Rainbow trout, this form, 

 named for its discoverer, Dr. Charles H. Gilbert, has always a white 

 tip to the dorsal fin. and there is generally some orange under the lower 

 jaw. In the lakes as Kern Lake, this species reaches a weight of eight 

 to ten pounds. In the mountain brooks it is very much smaller, but 

 i very where it is active, vigorous and gamy. 



GOLDEN TROUT OF MOUNT WHITNEY. 



The most beautiful of all our trout is the dainty little fish called 

 Golden trout, found in Volcano Creek, on the flanks of Mount Whitney, 

 the highest peak in the United States. This clear little stream flows 

 shallow and open, over rocks of orange-colored granite, or quartzite, 

 and the trout which are separated from the main body of Kern River 

 by a high waterfall called Aqua Bonita. have taken on the color of 

 the rocks on which thev lie.
