48 FISH-CULTURAL ASSOCIATION. 
outline of the life of the salmon of Grand lake; taking 
the time of impregnation as a starting point, the embryos hatch 
at six months of age, attain a length of three inches at one 
year; of eight inches at two years; of thirteen inches at three or 
four years; and of complete maturity (fifteen inches or more in 
length) at four or five years. Specimens twenty inches or more 
in length and weighing three pounds or upwards, I am inclined 
to regard as fish on their second visit to the spawning grounds, 
and on the assumption (of which there is, however, no direct 
proof) that they are like the anadromous salmon, biennial 
spawners—such fish are six or seven years old. 
Whether the same rate of growth prevails among the land- 
locked salmon in their other native haunts, there are no data to 
determine, but it is very probable that the entire period of growth 
is about the same, and accordingly that, in the case of the larger 
salmon of the Sebago the rate is greater. 
GROWTH IN NEW HOMES. 
When introduced to new haunts they have often grown to an 
unwonted size and sometimes at an accelerated rate. I will cite 
some instances: 
In Saipsic lake, Connecticut, in May, 1881, was captured a 
specimen twenty-two inches long and weighing 3 lbs., 14 oz. 
This was the growth from Schoodic fry, the first of which were 
planted in 1874. If this specimen was from the first planting it 
had grown to an unusual size for Schoodic fish. September 23rd, 
1881, another specimen was taken in the same lake, weighing 6 
lbs., 20z. One of 6 lbs., 8 oz. was reported to have been taken 
about the same time from one of the Twin lakes in Salisbury. 
In Shrewsbury pond, near Rutland, Vermont, specimens have 
been taken, I am told by Dr. C. H. Barber, weighing 6% lbs. 
One party caught twenty-three in one day, the smallest of which 
weighed 1% lbs., and the largest 6% lbs. This lake is one mile 
long, one-half mile wide and 160 feet deep. 
Woodhull lake, Herkimer County, N. Y., was stocked with fry 
of Schoodic salmon, in the summer of 1879. In the spring of 
1881, soon after the disappearance of the ice, several specimens
