t>2 AMERICAN FISHES 



down to the lateral line, dusky, inclining to green ; sides above the 

 lateral line marked with dusky spots ; along the lateral line, and both 

 a little above and a little below it, several dull obscure red spots. The 

 dorsal fin has twelve rays, marked with several dusky spots ; the pec- 

 toral fin has twelve rays of a dusky olive color ; the ventral fin eight 

 rays of a silvery white ; and the anal fin ten rays of the same color. 

 When the scales were carefully taken off with a knife, the obscure 

 red spots became of a fine vermillion, and were nineteen in number ; 

 and ten obscure oval bars of a dusky bluish color appeared, which 

 crossed the lateral line. In a young fry which has not acquired the 

 scales, these bars are very distinct. 



The above cut and description are both borrowed from Yarrel's 

 "British Fishes," the latter as quoted from Dr. Heysham's catalogue. 



To render these facts yet more certain, in the autumn of 1835, 

 Thomas Upton, Esq., of Ingmere Hall, near Kendal, began to en- 

 large a natural lake on his property, and in the spring of 1836, some 

 pinks from the Lune, a Salmon river in that vicinity, were put into it. 



This lake, which is called Lilymere, has no communication with any 

 other water, by which the fish once introduced can get out, or any fry, 

 from other waters, get in. The pinks, when put in, were certainly not 

 above two or three ounces each in weight. Sixteen months afterward, 

 a friend of Mr. Upton's being on a visit to him, caught with a red 

 palmer fly two Salmon Peal, in excellent condition, silvery bright in 

 color, measuring fourteen inches in length, and weighing fourteen 

 ounces ; one was cooked and eaten, the flesh pink in color, but not so 

 red as those of the river, well-flavored, and like that of a Peal. 



Ill the month of July, 1838, eleven months after, another small 

 Salmon was caught, equal to the first in condition and color, about 

 two inches longer, and three ounces heavier. No doubt was enter- 

 tained that these were two of the pinks transferred to the lake in the 

 spring of 1836, the first of which had been retained sixteen months, 

 and the latter twenty-seven months, in fresh-water. 



Farther than this, it was found that, in the river Hodder, the pinks 

 in April are rather more than three inches long, and that at the same 

 time smolts of six and a half are also taken, with the colors altered 

 as above, and ready to migrate. In July, the pink measures five inches, 

 and the smolts have then left the river.
