  The

  table 
  and 
  the 
  following 
  diagram 
  based 
  on 
  it 
  apply 
  

   to 
  the 
  three 
  most 
  important 
  food 
  fishes 
  of 
  the 
  banks— 
  the 
  cod, 
  had- 
  

   dock, 
  and 
  hake— 
  and 
  reduce 
  the 
  catches 
  for 
  the 
  several 
  years 
  enumer- 
  

   ated 
  to 
  a 
  common 
  basis 
  of 
  the 
  average 
  yield 
  per 
  trip, 
  which, 
  within 
  

   certain 
  limits, 
  may 
  be 
  considered 
  as 
  indicating 
  the 
  relative 
  annual 
  

   abundance 
  of 
  the 
  fish 
  in 
  the 
  regions 
  frequented 
  by 
  the 
  fishing 
  fleets.
