The  Grey  Trout;  Sea  Trout;  Bull  Trout  {bring,  Sw. ;
S.  ErioXj  Linn.),  was  common  with  us  in  the  autumn;
but  unless  identical  with  the  great  trout  of  the  Wenern,  it
was  only  found,  as  with  the  salmon  and  salmon  trout,  below
the  Falls  of  TroUhattan.  Owing  to  the  confusion  arising
from  local  names,  it  is  difficult  to  define  the  geographical
limits  of  this  fish ;  but  it  seems  common  during  the  season,
as  well  in  the  rivers  that  flow  into  the  Cattegat,  as  into  the
Baltic,  and  in  those  streams  that  empty  themselves  into  the
North  Sea.
The  salmon  trout,  as  also  the  salmon,  when  making  their
way  up  a  fjord  or  river,  are  said  to  hold  to  the  middle  of
the  stream,  and  to  the  deepest  water ;  but  the  grey  trout,
on  the  contrary,  is  believed  to  take  advantage  of  slacker
water.  It  is  also  recorded  of  this  species  that  they  proceed
into  much  shallower  water  than  the  salmon  trout  or  the
salmon  ;  to  such  shoals,  in  fact,  as  render  it  difficult  for
the   fishermen,  in  their  flat-bottomed  punts,  to  get  up  to

them.  Hence  the  established  fisheries  that  are  most  suc-
cessfiil  with  salmon,  are  not  equally  fortunate  with  the  grey
trout,  and  vice  versd.
The  grey  trout  is  very  tenacious  of  life,  and  exists  for
some  time  after  being  taken  out  of  its  native  element.
During  the  winter,  we  are  told,  it  may  be  kept  for  months
in  a  Sump,  or  fish-box ;  and  the  fish-dealers  believe  it  can
live  equally  well  in  fresh  as  in  salt  water.  It  is,  moreover,
said  of  this  trout,  that  when  put  into  spirits  of  wine,  it  lives
longer  than  most  other  fish.
