THE SEA-TROUT. 261 



one is firm and savoury to the taste, the other is " leather- 

 like and insipid." 



The bull-trout, Salmo eriox, as it is called, is by some 

 considered as a distinct species. Others assert that the 

 sea-trout and bull-trout are identical. Buckland says, 

 whether identical or not, he could pick out a bull-trout from 

 a thousand of the other kinds of Salmonidce. Between the 

 two fish all the Scotch fishermen consider there is a marked 

 difference. Buckland says : " I recollect hearing of some 

 Scotch fishers who had caught a curious-looking fish. 

 ' It's just a kelt/ said one. ' It's a bull-trout/ says another. 

 'It's a sea-trout,' says a third. ' What's the odds,' says 

 the tacksman, ' what you call him ? He'll just be a saumon, 

 worth is. 6d. per pound in the London market; shove him 

 into the ice-box.'" 



Day places the bull-trout as the northern form of sea- 

 trout, and Gunther considers Salmo eriox and cambricus 

 the same. 



Mr. Kerr, writing to Dr. Day, has made some very in- 

 teresting observations in relation to sewin and bull-trout, 

 and he sends a specimen of the fish he caught in the 

 river at Tan-y-Bwlch. He says : " It is a fair specimen of 

 what they call here sewin, which I take to be the Scotch 

 sea-trout. I have caught lots of fish precisely like this one 

 in the rivers flowing into St. Andrews Bay, and . from 

 there down to the English Border, and we always imagined 

 (though, it may be, wrongly) that they were all sea-trout. 

 There is a fish that I have caught in the Tweed and Tevtot 

 also very similar to this one, and called there the bull-trout; 

 here they give that name to yellow trout that have gone 

 down to the sea-water, but the fish I refer to, which I have 

 so frequently caught, but only in Tweed and Teviot, is a 

 true migratory species, and one which has often puzzled 

 me. I have caught a good many sewin in this river this 

 summer, and it has struck me that most of them were much 

 more like, both in appearance and when on the table, these 

 so-called bull-trout of the Border than the ordinary type of 

 Scotch sea-trout that I have caught in the Highlands and 

 elsewhere."
