THE SALMON AND SEWIN. 189 
these fish from acquiring the migratory dress and 
instinct of their species, evidently does not prevent 
them from increasing in growth and improving in 
condition, even the males which have shed their 
milt presenting every appearance of renovated 
health and vigour. 
Mr. Yarrell, in his ‘History of British Fishes,’ 
vol. il. p. 21, states that a large landed proprietor in 
Scotland, in April 1831, put a dozen or two of small 
Salmon-fry, three or four inches long, into a newly 
formed pond between three and four acres in extent. 
No fishing was allowed in this pond till the summer 
of 1833, when several of these Salmon were taken, 
weighing from two to three pounds, perfectly well- 
shaped, well-coloured, and well-flavoured. As these 
fish must have been in their second year when put 
into the pond, it follows that they attained to the 
weight of two or three pounds in rather more than 
three years. 
In the Supplement to the second volume of Mr. 
Yarrell’s work other examples of the growth of young 
Salmon in fresh water are given (pp. 5 & 6), from 
which it appears that in one instance there was an 
increase in weight of eleven or twelve ounces in 
sixteen months, and in another instance an in- 
crease of fourteen or fifteen ounces in twenty-seven 
months. 
I shall now proceed to inquire into the growth 
of the Salmon during its sojourn in the sea.
