  SURVEY 
  OF 
  FISHING 
  GEOUNDS, 
  1914. 
  

  

  this 
  report 
  as 
  rocky) 
  as 
  a 
  species 
  of 
  gravel 
  (described 
  as 
  granular 
  

   shale) 
  and 
  as 
  a 
  hard 
  mud. 
  Broken 
  bottom 
  consists 
  of 
  mixed 
  

   materials, 
  shale, 
  gravel, 
  sand, 
  and 
  mud, 
  in 
  patches 
  of 
  varying 
  sizes 
  

   and 
  composition, 
  but 
  always 
  rich 
  in 
  bottom-hving 
  organisms. 
  

  

  The 
  depths 
  are 
  indicated 
  by 
  curves 
  drawn 
  at 
  10-fathom 
  intervals, 
  

   but 
  the 
  soundings 
  which 
  have 
  been 
  made 
  off 
  this 
  coast 
  are 
  not 
  

   sufficiently 
  numerous 
  to 
  permit 
  more 
  than 
  approximate 
  location 
  of 
  

   the 
  hnes 
  in 
  many 
  cases. 
  

  

  The 
  locations 
  of 
  the 
  sets 
  made 
  during 
  the 
  survey 
  are 
  shown 
  by 
  

   Roman 
  numerals 
  (i 
  to 
  xliii), 
  the 
  center 
  of 
  the 
  space 
  covered 
  by 
  the 
  

   nimieral 
  being 
  the 
  position 
  of 
  the 
  set. 
  Fishing 
  trials 
  made 
  by 
  the 
  Idaho 
  

   and 
  the 
  Chicago 
  prior 
  to 
  the 
  investigation 
  are 
  shown 
  by 
  numbered 
  

   rectangles 
  and 
  circles, 
  respectively.
