  surface 
  film 
  of 
  mud 
  or 
  else 
  the 
  line 
  of 
  demarcation 
  between 
  the 
  two 
  

   extends 
  much 
  nearer 
  shore 
  than 
  has 
  been 
  shown 
  either 
  by 
  the 
  chart 
  

   or 
  the 
  soundings. 
  

  

  Southward 
  of 
  Coos 
  Bay, 
  extending 
  well 
  toward 
  the 
  Coquille 
  River, 
  

   is 
  a 
  comparatively 
  extensive 
  outcrop 
  of 
  shale, 
  rich 
  in 
  bottom 
  organ- 
  

   isms, 
  in 
  which 
  the 
  soundings 
  developed 
  two 
  areas 
  of 
  good 
  halibut 
  

   bottom, 
  fine 
  gravel. 
  The 
  soundings, 
  together 
  with 
  the 
  yield 
  of 
  set 
  

   XXVIII, 
  seem 
  to 
  indicate 
  that 
  more 
  detailed 
  examination 
  might 
  locate 
  

   areas 
  of 
  so-called 
  broken 
  bottom, 
  which 
  is 
  'more 
  productive 
  of 
  fish 
  

   than 
  shale 
  alone. 
  

  

  DISCUSSION 
  OF 
  THE 
  SETS. 
  

  

  In 
  table 
  i 
  will 
  be 
  found 
  all 
  pertinent 
  information 
  regarding 
  the 
  

   various 
  fishing 
  trials 
  made 
  during 
  the 
  survey, 
  with 
  the 
  exception 
  of 
  

   those 
  made 
  exclusively 
  for 
  scallops, 
  which 
  are 
  shown 
  in 
  table 
  ii. 
  

  

  In 
  some 
  cases, 
  instead 
  of 
  making 
  a 
  double-banked 
  set, 
  the 
  dories 
  

   were 
  spaced 
  about 
  a 
  half 
  mile 
  apart 
  and 
  acted 
  independently, 
  although 
  

   for 
  all 
  practical 
  purposes 
  they 
  were 
  making 
  but 
  a 
  single 
  set. 
  Double- 
  

   banked 
  sets 
  primarily 
  were 
  made 
  in 
  rough 
  and 
  threatenmg 
  weather 
  

   and 
  later 
  for 
  the 
  purpose 
  of 
  saving 
  time 
  and 
  making 
  several 
  sets 
  a 
  

   day 
  in 
  addition 
  to 
  the 
  routine 
  of 
  sounding. 
  These 
  are 
  indicated 
  in 
  

   the 
  column 
  "Addenda," 
  table 
  i. 
  

  

  The 
  skate 
  used 
  was 
  the 
  regular 
  8-line 
  trawl 
  as 
  rigged 
  and 
  used 
  by 
  

   commercial 
  fishermen, 
  carrying 
  about 
  250 
  hooks 
  spaced 
  9 
  feet 
  apart. 
  

   At 
  Newport, 
  July 
  to 
  August, 
  in 
  addition 
  to 
  the 
  regular 
  gear, 
  a 
  single 
  

   line 
  rigged 
  with 
  small 
  hooks 
  and 
  light 
  gangings 
  was 
  set 
  for 
  soles, 
  

   flounders, 
  and 
  other 
  smaU-mouthed 
  bottom 
  fish. 
  This 
  gear 
  was 
  not 
  

   very 
  effective 
  and 
  such 
  fish 
  as 
  were 
  taken 
  with 
  it 
  have 
  been 
  included 
  

   in 
  the 
  regular 
  columns 
  of 
  the 
  table. 
  

  

  The 
  bait 
  throughout 
  the 
  first 
  two 
  trips 
  and 
  in 
  part 
  during 
  the 
  New- 
  

   port 
  trials 
  was 
  salt 
  herring 
  purchased 
  in 
  Seattle, 
  not 
  in 
  preference 
  

   to 
  fresh 
  or 
  frozen 
  fish, 
  but 
  because 
  of 
  the 
  lack 
  of 
  facilities 
  on 
  the 
  

   Albatross 
  to 
  care 
  for 
  a 
  sufficient 
  quantity 
  of 
  cold-storage 
  bait. 
  At 
  

   Newport, 
  clams, 
  surf 
  perch, 
  and 
  salmon 
  were 
  obtained 
  from 
  the 
  local 
  

   fishermen, 
  but 
  were 
  not 
  always 
  to 
  be 
  had 
  in 
  sufficient 
  quantity, 
  

   and 
  salt 
  herring 
  were 
  used 
  to 
  make 
  up 
  the 
  deficiency. 
  A 
  small 
  

   stock 
  of 
  frozen 
  herring 
  was 
  obtained 
  from 
  a 
  supply 
  left 
  by 
  the 
  

   schooner 
  Daisy. 
  On 
  the 
  last 
  trip 
  of 
  the 
  Albatross, 
  through 
  the 
  

   special 
  efforts 
  of 
  the 
  commanding 
  officer, 
  several 
  boxes 
  of 
  iced 
  salmon 
  

   were 
  carried 
  in 
  the 
  ship's 
  very 
  limited 
  cold-storage 
  space. 
  

  

  The 
  weights 
  of 
  the 
  halibut 
  taken 
  are 
  given 
  under 
  different 
  classifi- 
  

   cations 
  in 
  table 
  i. 
  To 
  give 
  an 
  idea 
  of 
  the 
  proportion 
  of 
  first-class 
  

   fish, 
  weighing 
  from 
  11 
  to 
  80 
  pounds, 
  inclusive, 
  the 
  number 
  of 
  these 
  

   has 
  been 
  given 
  in 
  one 
  column 
  and 
  their 
  average 
  weight 
  in 
  another.
