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 to
that spot. The fishermen near Glouces-

were conducted, found that in those
places where eggs of cod had been

and of about the size which these fish
would naturally attain in two years,
