  As 
  shown 
  in 
  the 
  foregoino; 
  table, 
  the 
  increase 
  in 
  the 
  cod 
  catch 
  

   has 
  been 
  due 
  to 
  some 
  extent 
  to 
  an 
  increase 
  in 
  the 
  relative 
  quantities 
  

   of 
  the 
  smaller 
  sizes 
  landed, 
  and 
  the 
  decrease 
  in 
  the 
  quantities 
  of 
  

   haddock 
  and 
  plaice, 
  especially 
  the 
  latter, 
  has 
  occurred 
  notwithstand- 
  

   ing 
  the 
  marketing 
  of 
  an 
  increased 
  proportion 
  of 
  the 
  small 
  and 
  

   •medium 
  sizes. 
  

  

  The 
  statistical 
  facts 
  of 
  this 
  fisliery, 
  so 
  far 
  as 
  they 
  may 
  be 
  given 
  

   weight 
  on 
  account 
  of 
  the 
  brief 
  period 
  covered, 
  point 
  rather 
  strongly 
  

   to 
  the 
  possible 
  depletion 
  of 
  the 
  plaice 
  fishery 
  and 
  to 
  a 
  less 
  extent 
  

   of 
  the 
  fishery 
  for 
  haddock. 
  The 
  cod, 
  as 
  appears 
  to 
  be 
  the 
  case 
  

   everywhere, 
  is 
  unaffected. 
  

  

  In 
  1906 
  there 
  were 
  346 
  voyages 
  by 
  English 
  steam 
  liners, 
  aggre- 
  

   gating 
  7,526 
  days 
  of 
  absence 
  per 
  port, 
  and 
  of 
  an 
  average 
  duration 
  

   of 
  21.7 
  days. 
  In 
  1912 
  there 
  were 
  521 
  voyages, 
  entailing 
  an 
  aggre- 
  

   gate 
  absence 
  of 
  10,268 
  days, 
  and 
  the 
  average 
  voyage 
  occupied 
  19.6 
  

   days. 
  The 
  total 
  catch 
  of 
  these 
  steam 
  liners 
  and 
  the 
  average 
  catch 
  

   per 
  voyage 
  are 
  shown 
  in 
  the 
  following 
  tables 
  :

  It 
  will 
  be 
  seen 
  that 
  no 
  plaice 
  were 
  taken 
  in 
  these 
  fisheries, 
  and 
  the 
  

   catch 
  of 
  haddock, 
  the 
  other 
  species 
  of 
  particular 
  significance 
  in 
  this 
  

   inquiry, 
  was 
  negligible. 
  The 
  decrease 
  in 
  flat 
  fishes 
  is 
  due 
  to 
  the 
  

   halibut, 
  the 
  principal 
  species 
  of 
  that 
  class 
  taken 
  by 
  the 
  liners.
