  and 
  their 
  larvae, 
  it 
  occasionally 
  extends 
  its 
  range 
  to 
  streams 
  strewn 
  

   with 
  bowlders 
  and 
  broken 
  rocks. 
  

  

  Unhke 
  the 
  native 
  trout, 
  the 
  grayling 
  will 
  go 
  long 
  distances, 
  if 
  

   necessary, 
  to 
  find 
  suitable 
  spawning 
  grounds. 
  They 
  spawn 
  in 
  April 
  

   and 
  May 
  on 
  gravelly 
  shallows. 
  In 
  the 
  north 
  fork 
  of 
  the 
  Madison 
  

   River, 
  where 
  the 
  water 
  is 
  comparatively 
  warm, 
  coming 
  from 
  the 
  

   Firehole 
  River 
  in 
  the 
  Yellowstone 
  Park, 
  the 
  grayling 
  spawns 
  a 
  month 
  

   earlier 
  than 
  in 
  any 
  other 
  waters 
  in 
  Montana. 
  

  

  In 
  point 
  of 
  activity 
  it 
  even 
  excels 
  the 
  native 
  trout, 
  when 
  hooked 
  

   breaking 
  the 
  water 
  repeatedly 
  in 
  its 
  effort 
  to 
  escape, 
  which 
  the 
  trout 
  

   seldom 
  does. 
  It 
  takes 
  the 
  artificial 
  fly 
  eagerly, 
  and 
  if 
  missed 
  at 
  the 
  

   first 
  cast 
  wiU 
  rise 
  again 
  and 
  again 
  from 
  the 
  depths 
  of 
  the 
  pool, 
  whereas 
  

   the 
  trout 
  wiU 
  seldom 
  rise 
  a 
  second 
  time 
  without 
  a 
  rest. 
  It 
  will 
  also 
  

   take 
  various 
  baits, 
  such 
  as 
  caddis-fly 
  larvae, 
  grasshoppers, 
  and 
  worms. 
  

   Among 
  the 
  recommended 
  flies 
  are

  As 
  a 
  food 
  fish 
  it 
  is 
  even 
  better 
  than 
  the 
  trout. 
  Its 
  flesh 
  is 
  firm 
  and 
  

   flaky, 
  very 
  white, 
  and 
  of 
  delicate 
  flavor.

  Native 
  Whitefish; 
  Rocky

  Whitefish 
  (Coregonus 
  

  

  williamsoni) 
  . 
  

  

  The 
  Rocky 
  Mountain 
  whitefish 
  occurs 
  in 
  all 
  suitable 
  waters 
  on 
  the 
  

   west 
  slope 
  of 
  the 
  Rockies 
  from 
  Utah 
  to 
  British 
  Columbia. 
  A 
  scarcely, 
  

   if 
  at 
  all, 
  distinguishable 
  variety 
  or 
  subspecies 
  bearing 
  the 
  name 
  of 
  

   Coregonus 
  williamsoni 
  cismontanus 
  is 
  found 
  in 
  certain 
  waters 
  of 
  the 
  

   upper 
  Missouri 
  Basin. 
  

  

  In 
  some 
  locahties 
  this 
  fish 
  is 
  miscalled 
  grayluig,* 
  with 
  which 
  it 
  

   should 
  not 
  be 
  confused, 
  as 
  it 
  is 
  a 
  very 
  different 
  species; 
  and 
  there 
  

   seems 
  to 
  be 
  a 
  local 
  Yellowstone 
  River 
  name, 
  the 
  phonetic 
  spelhng 
  of 
  

   which 
  is 
  "sterlet" 
  or 
  "steret."

  Referring 
  to 
  the 
  fishing 
  in 
  the 
  canyon 
  of 
  Sunhght 
  Creek, 
  Clark 
  Fork, 
  Mr. 
  Clark 
  probably 
  made 
  this 
  

   mistake 
  in 
  writing 
  the 
  following: 
  " 
  You 
  wUl 
  probably 
  first 
  catch 
  a 
  scaly 
  fish 
  which 
  looks 
  like 
  a 
  long 
  sucker. 
  

   It 
  is 
  the 
  Montana 
  grayling 
  and 
  there 
  are 
  many 
  down 
  there.
