same fish exists. It is doubtful if Prof. Agassiz would give that name 

 to this fish now, at all events. Opposed to this view of its origin is 

 the fact that there does not now exist, and has not existed for many 

 years, any obstacle to the passage of these fish to the sea. At least 

 this is the fact in some localities where they are found. Until within 

 a few years the Schoodic salmon descended the San Croix river as far 

 as Calais, and from this point it is an open run to the sea. But in 

 support of this theory is the fact that both on this continent and in 

 Scandinavia, land-locked salmon are found only in inland waters to 

 which sea-salmon penetrate, or once had access to, in their summer migra- 

 tions. My friend, the learned secretary of this Association, argues 

 with much skill that the land-locked salmon is entitled to the rank 

 of a distinct species. He claims that its size, robustness and spirit, 

 and above all the difference in the number of eggs it deposits, form 

 sufficient testimony against the theory that this fish is a sea-salmon, 

 dwarfed by the suppression of one of its strongest instincts. 



That veteran angler and fish culturist, Mr. Thaddeus Norris, of 

 Philadelphia, says, on this siibject, that " many years ago a few sea- 

 salmon finding the large Schoodic lakes to be convenient feeding 

 grounds, passed the Avinter in them, and their progeny, taking this to 

 be the established habit of their fathers, like the good Pennsylvania 

 Dutchmen, preferred to walk or swim in the same path." 



Mr. Norris cites the most authentic instance in which sea-salmon 

 were known to be actually land-locked, and the eft'ect it had on their 

 progeny. 



" The first and the least of all are those Lilliputians found in Loch 

 Lomond, which supplies the city of St. John's, New Brunswick, 

 with water. The Mispeck, which discharges that body of water 

 covering about three square miles, twenty years ago was dammed for 

 milling purposes, and some of the sea-salmon which had been 

 migrating to and from the lake, remained and reproduced. The 

 lake being small and of inconsiderable depth, furnished a very 

 limited supply of food, and as a consequence each generation attained 

 a less size than its predecessor, until the descendants of the lordly 

 anadromous salmon are now reduced to the length of nine inches. I 

 have seen strings of them there, and their average size does not exceed 

 this. They are so small as not to deserve the name of salmon, 

 and are called " white trout." Yet they are true salmon ; and, if the 

 dams below were taken away, and they descended to sea for as many 

 years as they have been debarred from it, would attain their normal 

 size."
