Prof. Baird, of the Fish commission,
thinks that saltwater fish are migra,
tory. If they are reared at given
spot along the shore they will return ta
that spot. The fishermen near Glouces-
ter. Mass. where some experiments
were conducted, found that in those
places where eggs of cod had been
Matched large quantities of this variety.
and of about the size which these fish
would naturally attain in two years,
were to be had in two years after the
eggs had been placed there. They
came to the conclusion that the fish had
returned to their old haunts, and they
gave them the name of 1.-The Fish Com
