  How 
  long 
  trout 
  have 
  existed 
  in 
  Lochnagar 
  

   I 
  do 
  not 
  know, 
  but 
  I 
  have 
  taken 
  them 
  there. 
  

  

  Common 
  in 
  every 
  stream 
  and 
  loch, 
  assuming 
  endless 
  

   variation 
  in 
  form 
  and 
  colour, 
  and 
  receiving 
  an 
  equally 
  

   endless 
  list 
  of 
  names. 
  

  

  Salmo 
  umbla, 
  Linn. 
  Northern 
  Char. 
  Alpine 
  Char. 
  

   Red 
  Wame. 
  

  

  Salmo 
  sahelinus, 
  MacGillivray's 
  Natural 
  History 
  of 
  Deeside, 
  

   in 
  which 
  it 
  is 
  stated, 
  " 
  Dr. 
  Adams 
  says 
  he 
  believes 
  this 
  fish 
  

   to 
  have 
  been 
  introduced 
  into 
  the 
  Loch 
  of 
  Dunn 
  and 
  other 
  

   lakes 
  on 
  Deeside." 
  I 
  assume 
  that 
  it 
  is 
  the 
  Loch 
  of 
  Drum 
  

   that 
  is 
  meant. 
  

  

  Char 
  exists 
  in 
  Loch 
  Builg, 
  in 
  Banffshire, 
  about 
  fourteen 
  

   miles 
  from 
  Ballater. 
  On 
  June 
  12th, 
  1890, 
  one 
  of 
  2J 
  to 
  3 
  lbs. 
  

   was 
  caught 
  in 
  a 
  salmon 
  net 
  below 
  the 
  Bridge 
  of 
  Dee, 
  and 
  I 
  

   had 
  one 
  similarly 
  caught, 
  but 
  under 
  1 
  lb. 
  weight, 
  near 
  the 
  

   same 
  locality, 
  but 
  it 
  is 
  not 
  plentiful 
  in 
  the 
  streams 
  of 
  Kin- 
  

   cardine, 
  Aberdeen, 
  Banff, 
  or 
  Moray 
  shires. 
  

  

  Occurs 
  in 
  Loch 
  Knockie, 
  Inverness- 
  shire, 
  but 
  " 
  common 
  in 
  

   some 
  of 
  the 
  lochs 
  throughout 
  the 
  county 
  of 
  Sutherland." 
  

   {Fauna 
  of 
  Sutherlandshire, 
  p. 
  290.) 
  This 
  form, 
  however, 
  is 
  now 
  

   held 
  to 
  be 
  merely 
  a 
  variety 
  of 
  the 
  common 
  trout. 
  

  

  Of 
  late 
  years, 
  it 
  has 
  become 
  a 
  habit 
  to 
  introduce 
  varieties 
  

   of 
  trout 
  to 
  our 
  northern 
  rivers 
  that 
  are 
  not 
  indigenous 
  to 
  the 
  

   country. 
  This 
  may 
  be 
  beneficial 
  from 
  a 
  food 
  point 
  of 
  view, 
  

   but 
  from 
  a 
  natural 
  history 
  one 
  it 
  is 
  calculated 
  to 
  cause 
  

   confusion, 
  especially 
  when 
  such 
  have 
  been 
  introduced 
  without 
  

   the 
  fact 
  having 
  been 
  made 
  public. 
  Thus, 
  in 
  1898, 
  over 
  a 
  

   thousand 
  rainbow 
  trout 
  were 
  brought 
  from 
  Lancashire 
  and 
  put 
  

   into 
  the 
  river 
  Bucket, 
  a 
  tributary 
  of 
  the 
  Don.

  Common 
  in 
  the 
  Firth 
  of 
  Forth 
  and 
  Firth 
  of 
  Tay, 
  where 
  

   it 
  is 
  taken 
  in 
  great 
  quantities 
  during 
  the 
  autumnal 
  months 
  

   and 
  onward 
  more 
  sparingly 
  till 
  the 
  end 
  of 
  March. 
  Not 
  known 
  

   along 
  the 
  coasts 
  of 
  Kincardine 
  and 
  Aberdeen 
  shires. 
  For 
  

   Banffshire, 
  Edward 
  says 
  " 
  rare 
  with 
  us."
