Why it should descend the Androscoggin as far as Berlin with the apparent intention 

 of going farther is an unanswerable question. 



Elmer Bean, of Berlin, N. H., informed the writer that some years ago two speci- 

 mens of whitefish were found in the grate of the flume of a pulp mill at Berlin and that 

 he had frequently caught them on bait at the mouth of Molnichwock Brook. In 1905 

 one, 12% inches long, was taken by the Bureau of Fisheries' party in a gill net in the 

 deep hole off Sunday Cove August 17, and one, 16 inches long, was caught on a hook 

 and line at the mouth of Molnichwock Brook July 17. 



SEA SALMON {Sal-mo salar). 



The Atlantic salmon, sometimes designated as sea salmon to distinguish it from 

 the fresh-water or so-called landlocked salmon, is a resident of the north Atlantic along 

 the coasts of Europe and America, ascending all suitable streams. In Maine the 

 Androscoggin was one of a number of rivers formerly ascended by the salmon, but 

 owing to impassable falls it never reached the Rangeley Lakes. The only interest 

 attached to this species so far as those lakes are concerned is in the fact that a number 

 has been introduced there from time to time and the possibility of their having con-

tributed to the salmon stock of the lakes. The following plants were made: Ten thou- 

 sand fry in 1873; 99,000 fry in 188 1 ; 194,600 fry in 1882; 1,000 yearlings in 1 900-1 901. 



The differences by which this species can be distinguished from the landlocked 

 salmon are slight and by the ordinary observer would probably not be noticed. The 

 most conspicuous external characteristics are the smaller, more pointed head, more 

 slender caudal peduncle, more numerous scales," and radical difference in color in the 

 adult sea salmon. So far as relates to the desired or undesired result of its introduction 

 into these waters, its distinguishing characteristics are of little moment now. The 

 desired result was to furnish fish for the angler. To him its structure is of no concern 

 so long as its size and gameness are satisfactory, its table qualities being equal to those 

 of the other species. The undesired results are its effects upon other fishes. Its feed- 

 ing habits in these waters probably would not differ from the landlocked salmon, and 

 its effects upon the game fishes would likely be the same as in the case of the landlocked 

 salmon. 



The first salmon caught of which there is any record was taken in 1875 and weighed 

 one-half pound. This might possibly have been from the plant of Schoodic salmon of 

 1874, but that is a pretty good growth from fry in one year. Another weighing 2
