THE LAND-LOCKED SALMON. lOI 



of the Pike's eye inside. I have always wondered why the 

 leader was not cut by his teeth, but suppose it got between 

 them. These Pike run to great size in Lake St. John, and up 

 the Peribonca. 



The "Wall-eyed Pike" {Liicioperca Americana, Gunther; 

 Stizostediuui Vit renin, Jordan & Gilbert), called in Canada 

 Dore, from his golden yellow sides, is also rather too abundant 

 in these waters. Though the lakes in the Saguenay region 

 and the upper parts of the rivers tributary to Lake St. John 

 and the Saguenay abound with Trout, there are none in Lake 

 St. John itself, nor in the lower portions of its tributaries 

 and the Grande Decharge. In the latter there seems to be too 

 much water for them in the rocky parts of the river, and in 

 the calm reaches the bottom and banks are too clayey. An- 

 other reason for their absence is probably the high summer' 

 temperature of the water in Lake St. John, which is simply 

 a vast evaporating-pan, being comparatively shallow in pro- 

 portion to its area of about six hundred square miles, and 

 with a bottom of sand and silt washed down by the dozen 

 rivers, three of them very large and over two hundred miles 

 long, which discharge into it. 



That a true Salmon like the Wananishe inhabits such water, 

 is another instance of its curious variation in habits, and a 

 proof of adaptation to changed conditions. This is a subject 

 which I should have liked to discuss here, especially in view 

 of the growing idea I have, which is confirmed to some extent 

 by the results of the accurate and instructive experiments in 

 artificial breeding by Sir James Maitland, at the Howietoun 

 establishment in Scotland, by the results at the Canadian 

 Government's fish hatchery at Tadoussac, and by observa- 

 tion of Salmon rivers, that the Salmon may not be necessarily 

 an anadromous fish, but is only so from choice, just as the 

 Trout of Long Island and many other places are, and that, 

 under certain circumstances of difficulty of descent, combined 

 with abundance of food in large bodies of fresh water, it — or
