THE LAXD-LOCKED SALMON. 83 



in this instance does not amount to so much as is often found 

 in Brook Trout inhabiting the same waters, to say nothing of 

 the wide differences in color and form between Trout of differ- 

 ent locahties. 



The same fish occurs in several lakes in Nova Scotia, where 

 it is erroneously called "Grayling," in Lock Lomond and 

 other lakes in New Brunswick, and according to Mr. Hallock, 

 in the lakes of Peterborough County, Ontario. It is possible 

 that the Salmon, which within this generation's memory 

 abounded in Lake Ontario, were also purely fresh-water fish. 

 That at least is the opinion of Mr. Wilmot, the superin- 

 tendent of the Canadian Government Fish Hatcheries, who 

 has studied them all his life. The "Silfverlax," or Lake Sal- 

 mon of Wenern and other Swedish lakes — the Sal mo Argoi- 

 tcus of Swedish naturalists — corresponds very closely, both as 

 to the descriptions of its appearance and the circumstances 

 under which it is found, with the others above mentioned. 

 In British Columbia, too, a lake Salmon is found, concerning 

 which my information is at present too meager to enable me 

 to say more than that it is highly probable that under similar 

 circumstances some of the Pacific Salmon, admittedly quite 

 distinct species from the Sahno Salar of the Atlantic, have 

 acquired a fresh-water habitat. In some of the rivers of 

 Labrador, which are all simply the connections between, and 

 discharges of, extensive lake systems. I found and identified, 

 in 1889, my well-known friend, the Wananishe. It will, there- 

 fore, be seen that the range of this fish, so far from being 

 limited, is very extensive. The probability is that as oppor- 

 tunities for skilled investigation multiply, it will be found in 

 many other places. 



Three things are noteworthy about its distribution. It is 

 always found at the head-waters of rivers to which Salmon 

 actually resort now, or to which they are known to have 

 resorted. Though in some places there are apparently in- 

 superable obstacles in the way of its ascent from the sea,
