  1891 
  to 
  1901, 
  inclusive, 
  were 
  taken 
  by 
  this 
  class 
  of 
  vessels. 
  The 
  

   trend 
  of 
  the 
  catch 
  of 
  demersal 
  fishes 
  by 
  steam 
  trawlers 
  is 
  therefore 
  

   indicated 
  by 
  that 
  of 
  first-class 
  vessels 
  as 
  a 
  whole. 
  After 
  1902 
  the 
  

   information 
  is 
  specifically 
  given 
  and 
  is 
  shown 
  in 
  the 
  following 
  table 
  : 
  

  

  Quantities 
  of 
  Demersal 
  Fishes, 
  Classes, 
  and 
  Certain 
  Kinds 
  from 
  the 
  

   North 
  Sea 
  Landed 
  on 
  .the 
  East 
  Coast 
  of 
  England 
  by 
  First-Class 
  Steam 
  

   Trawlers 
  in 
  the 
  First 
  and 
  Last 
  Years 
  of 
  Certain 
  Periods. 
  

  

  Note.— 
  The 
  quantities 
  for 
  1906 
  are 
  the 
  landing 
  in 
  England 
  and 
  Wales, 
  but 
  almost 
  if 
  not 
  quite 
  all 
  were 
  

   landed 
  on 
  the 
  east 
  coast. 
  

  

  As 
  the 
  cod, 
  haddock, 
  and 
  plaice 
  are 
  the 
  important 
  species, 
  the 
  

   foregoing 
  data 
  dealing 
  with 
  single 
  years 
  have 
  been 
  checked 
  by 
  

   comparing 
  the 
  catches 
  of 
  these 
  species 
  for 
  three 
  overlapping 
  four- 
  

   year 
  periods 
  between 
  1903 
  and 
  1912, 
  inclusive. 
  It 
  will 
  be 
  seen 
  thai 
  

   the 
  results 
  are 
  essentially 
  similar, 
  as 
  indicated 
  by 
  the 
  trend 
  of 
  the 
  

   total 
  catches 
  of 
  these 
  species 
  by 
  trawlers 
  in 
  the 
  North 
  Sea.

  Cod, 
  Haddock, 
  and 
  Plaice 
  by 
  Steam 
  

   Trawlers 
  in 
  the 
  North 
  Sea, 
  1906 
  to 
  1909, 
  and 
  1909 
  to 
  1912, 
  Compared 
  

   WITH 
  1903 
  to 
  1906. 
  

  

  It 
  appears 
  that 
  the 
  catch 
  of 
  demersal 
  fish 
  in 
  the 
  North 
  Sea 
  by 
  

   steam 
  trawlers 
  decreased 
  from 
  1891 
  to 
  1898 
  and 
  increased 
  sufficiently 
  

   from 
  1898 
  to 
  1901 
  to 
  show 
  a 
  small 
  net 
  increase 
  for 
  the 
  entire 
  period,
