  On 
  the 
  "east 
  coast 
  grounds," 
  which 
  include 
  the 
  fishing 
  grounds 
  

   nearest 
  to 
  Aberdeen, 
  to 
  which 
  the 
  voyages 
  were 
  shortest, 
  most 
  fre- 
  

   quent, 
  and 
  most 
  numerous, 
  and 
  on 
  which 
  the 
  catch 
  per 
  voyage 
  

   was 
  least, 
  there 
  has 
  been 
  an 
  increase 
  in 
  the 
  proportionate 
  quantity 
  

   of 
  the 
  small 
  sizes 
  of 
  all 
  three 
  species. 
  In 
  the 
  case 
  of 
  the 
  cod 
  there 
  

   have 
  been 
  a 
  decrease 
  in 
  the 
  actual 
  quantity 
  of 
  large 
  cod 
  and 
  an 
  

   increase 
  in 
  the 
  small, 
  the 
  species 
  as 
  a 
  whole 
  remaining 
  stationary. 
  

   In 
  the 
  haddock 
  both 
  the 
  total 
  and 
  the 
  several 
  sizes 
  have 
  decreased 
  

   in 
  average 
  catch, 
  with 
  small 
  decreases 
  in 
  the 
  proportion 
  of 
  large 
  

   and 
  medium 
  sizes, 
  and 
  a 
  corresponding 
  increase 
  in 
  the 
  proportion 
  

   of 
  small 
  ones. 
  In 
  the 
  plaice 
  there 
  was 
  an 
  increase 
  in 
  the 
  catch, 
  

   owing 
  solely 
  to 
  a 
  material 
  increase

  the 
  small,
