﻿EEPOKT 
  OF 
  THE 
  COMMISSIONER 
  OF

  therefor: 
  Sequoia, 
  Cal.; 
  Mesa 
  Verde, 
  Colo.; 
  Glacier, 
  Mont.; 
  Crater 
  

   Lake, 
  Oreg.; 
  Wind 
  Cave, 
  S. 
  Dak.; 
  and 
  Yellowstone, 
  Wyo. 
  It 
  has 
  

   been 
  determined 
  to 
  make 
  annual 
  distribution 
  of 
  fish 
  for 
  a 
  period 
  of 
  

   9 
  or 
  10 
  years 
  in 
  each 
  of 
  these 
  parks. 
  Inasmuch 
  as 
  there 
  have 
  been 
  

   extensive 
  fish-cultural 
  operations 
  in 
  the 
  Yellowstone 
  Park 
  for 
  a 
  

   number 
  of 
  years, 
  no 
  adchtional 
  steps 
  are 
  necessary 
  for 
  maintaining 
  

   the 
  fish 
  supply 
  in 
  that 
  territory. 
  

  

  No 
  fishery 
  explorations 
  have 
  yet 
  been 
  made 
  in 
  the 
  Yosemite, 
  

   General 
  Grant, 
  Piatt, 
  and 
  Mount 
  Rainier 
  Parks; 
  but 
  as 
  soon 
  as 
  

   practicable 
  the 
  streams 
  and 
  lakes 
  therein 
  wiU 
  be 
  examined 
  and 
  the 
  

   matter 
  of 
  stocking 
  them 
  will 
  receive 
  careful 
  attention. 
  

  

  The 
  arrangements 
  thus 
  far 
  made 
  with 
  the 
  Forest 
  Service 
  contem- 
  

   plate 
  annual 
  plants 
  of 
  fish 
  in 
  some 
  700 
  lakes 
  and 
  streams 
  in 
  those 
  

   portions 
  of 
  Colorado 
  and 
  Wyoming 
  embracing 
  the 
  forest 
  reservations 
  

   of 
  Arapahoe, 
  Battlement, 
  Big 
  Horn, 
  Bonneville, 
  Bridger, 
  Cochetopa, 
  

   Colorado, 
  Durango, 
  Gunnison, 
  Hayden, 
  Holy 
  Cross, 
  Leadville, 
  

   Medicine 
  Bow, 
  Montezuma, 
  Pike, 
  Rio 
  Grande, 
  Routt, 
  San 
  Isabel, 
  

   San 
  Juan, 
  Shoshone, 
  Sopris, 
  Uncompahgre, 
  Washakie, 
  and 
  White 
  

   River. 
  

  

  In 
  making 
  distributions 
  in 
  the 
  national 
  parks 
  and 
  forests, 
  the 
  fish 
  

   wiU 
  be 
  dehvered 
  at 
  the 
  railroad 
  stations 
  nearest 
  the 
  waters 
  to 
  be 
  

   stocked, 
  and 
  the 
  park 
  superintendents 
  or 
  forest 
  rangers 
  will 
  transport 
  

   them 
  thence 
  to 
  the 
  waters 
  for 
  which 
  destined. 
  This 
  plan 
  will 
  facihtate 
  

   the 
  distributions 
  of 
  fish 
  in 
  isolated 
  lakes 
  and 
  streams 
  in 
  the 
  moun- 
  

   tains, 
  which 
  could 
  not 
  be 
  reached 
  directly 
  by 
  the 
  Bureau 
  without 
  

   entaiUng 
  heavy 
  expense. 
  As 
  the 
  national 
  parks 
  and 
  forests 
  are 
  

   located 
  for 
  the 
  most 
  part 
  in 
  mountainous 
  districts, 
  the 
  various 
  species 
  

   of 
  trout 
  are 
  best 
  adapted 
  for 
  stocking 
  them.

  OCEANOGRAPHIC 
  INVESTIGATIONS. 
  

  

  Oceanography, 
  which 
  embraces 
  the 
  biology, 
  physics, 
  and 
  chemistry 
  

   of 
  the 
  sea, 
  has 
  been 
  used 
  with 
  considerable 
  effect 
  in 
  the 
  elucidation 
  

   of 
  obscure 
  fishery 
  problems, 
  especially 
  in 
  the 
  North 
  Sea. 
  The 
  

   Bureau 
  has 
  recently 
  improved 
  its 
  equipment 
  for 
  such 
  work 
  and 
  is 
  

   systematizing 
  its 
  methods 
  and 
  plan 
  of 
  operation 
  along 
  the 
  lines 
  which 
  

   experience 
  elsewhere 
  has 
  shown 
  to 
  be 
  effective. 
  

  

  During 
  the 
  summer 
  of 
  1913 
  the 
  schooner 
  Grampus 
  was 
  engaged 
  in 
  

   investigations 
  of 
  this 
  character 
  between 
  the 
  Gulf 
  of 
  Maine 
  and 
  the 
  

   capes 
  of 
  the 
  Chesapeake, 
  incidentally 
  discovering 
  the 
  scallop 
  beds 
  

   which 
  have 
  been 
  elsewhere 
  referred 
  to. 
  During 
  February 
  and 
  

   March 
  the 
  Bureau 
  cooperated 
  with 
  the 
  Coast 
  and 
  Geodetic 
  Survey 
  

   in 
  an 
  oceanographic 
  expedition 
  from 
  the 
  capes 
  of 
  the 
  Chesapeake 
  to 
  

   Bermuda 
  and 
  thence 
  to 
  the 
  coast 
  of 
  Florida, 
  including 
  several 
  lines 
  

   of 
  observation 
  across 
  the 
  GuH 
  Stream 
  as 
  far 
  south 
  as 
  Key 
  West 
  and 
  

   Habana. 
  These 
  two 
  projects 
  resulted 
  in 
  the 
  collection 
  of 
  a 
  large 
  

   amount 
  of 
  data 
  and 
  many 
  specimens 
  which 
  there 
  has 
  not 
  yet 
  been 
  

   tune 
  to 
  coUate 
  and 
  study. 
  It 
  is 
  evident, 
  however, 
  that 
  the 
  work 
  

   wiU 
  not 
  only 
  result 
  in 
  the 
  accumulation 
  of 
  much 
  information 
  in 
  regard 
  

   to 
  ocean 
  currents, 
  saHnities, 
  and 
  temperatures, 
  aU 
  of 
  which 
  are 
  

   important 
  in 
  the 
  distribution 
  of 
  fishes 
  and 
  the 
  determination 
  of 
  the 
  

   locale 
  of 
  fisheries, 
  but 
  there 
  has 
  been 
  a 
  more 
  direct 
  gain 
  in 
  the 
  knowl-
