G. Atkins, who says, in letter dated Grand Lake Stream, Maine, November 27, 
1880, “I send * * * four male land-locked salmon and four females, whose eggs 
have been taken from them by the artificial process. They are as near spent fish as 
we can get, but I think they are in better condition than those that have spawned 
naturally.” The following measurements and weights indicate the size of the fish
