50 The Natural History of the Salmon, 



salmon particular to the Tweed, termed the grey 

 salmon, which appears in the river the latter end of 

 November, and at times later." This observer states 

 that ^^ grilse do not become salmon^ as is proved this 

 season, a kelt grilse, marked in March or April 

 last, was recaptured at North Bells in August as a 

 clean grilse." 



John Weatherstone, Fisherman, Horncliffe, 

 says : " I know only two kinds of salmon that enter 

 the Tweed, the Tweed salmon and the Norweg- 

 ian salmon. The latter is known chiefly by its having 

 maggots or worms on the gills, and having the 

 scales of a trout and the fins and tail of a salmon. 

 Then we have the grilse, which is easily known to 

 the practical fisherman, although many times larger 

 than the salmon ; but the marks and distinction 

 between salmon proper and the grilse is so fine, 

 that I cannot convey or use words to make the 

 difference known ; " he also distinctly states in 

 answer to the question, " If you consider grilse 

 become salmon," " I believe that a grilse never 

 becomes a salmon^ but it continues to be a grilse." 



Mr. James Smith, Water Baihff, says: *' I don't 

 consider grilse become salmon.''
