EAINBOW TEOUT AND ITS COUSIlirS 



As the angler goes south in California and crosses the Line 

 into Lower California the rainfall becomes perceptibly less, and 

 wMle there are a number of streams, but one, the Eio San Eamon, 

 flows continuously to the sea. This trout stream runs in La 

 GruUa Meadows on the west side of the San Pedro Martyr range, 

 at an altitude of seven thousand feet, and about one hundred 

 and fifty nules south of San Diego, U.S.A. It runs through 

 a rocky canon, and there are rainbows in it at various points. 

 Trout are also found in the stream of the Sierra Madre in Chihua- 

 hua, near the border of Durango and Sinaloa, at an altitude of 

 eight thousand feet. There are also trout in the Eio Yaqui, 

 which flows down from the mountains through the richest land 

 in Mexico — the delta of the Eio Yaqui near Esperanza. 



The Lower California trout is a rainbow, Sdlmo nelsoni, 

 and in the Eio Eamon is very game. Dr. Joseph GrinneU of the 

 University of California, found, in 1907, a new trout in the 

 upper reaches of the Eio Santa Ana, about seventy nules from 

 Los Angeles. It is also of the rainbow series, and is named 

 Salmo evermanni, in honour of Dr. Evermann, the distinguished 

 authority on fishes. 



The Kootenay Lake in British Columbia, a tributary of the 

 Columbia river, has produced some extremely large trout closely 

 related to the steelhead or rainbow. One of twenty-two 

 pounds was examined by Dr. Jordan and pronounced Salmo 

 kamloops, a fine trout of elegant proportions, an ideal game fish.
