  was 
  deposited 
  by 
  the 
  streams 
  — 
  often 
  to 
  a 
  depth 
  of 
  several 
  feet 
  — 
  it 
  

   has 
  the 
  characteristics 
  of 
  quicksand 
  and 
  is 
  extremely 
  dangerous 
  to 
  

   cross. 
  Such 
  places 
  have 
  been 
  used 
  by 
  only 
  a 
  small 
  number 
  of 
  spawn- 
  

   ing 
  salmon, 
  and 
  it 
  may 
  be 
  safely 
  asserted 
  that 
  they 
  are 
  now 
  wholly 
  

   unfit 
  for 
  the 
  deposit 
  of 
  spawn. 
  In 
  the 
  streams 
  and 
  unnamed 
  creeks 
  

   of 
  the 
  southern 
  end 
  of 
  the 
  island, 
  very 
  little 
  of 
  this 
  material 
  remains, 
  

   and 
  what 
  little 
  was 
  found 
  in 
  the 
  streams 
  during 
  the 
  summer 
  consisted 
  

   almost 
  entirely 
  of 
  sand, 
  which 
  can 
  hardly 
  be 
  considered 
  more 
  injurious 
  

   to 
  the 
  spawning 
  beds 
  than 
  the 
  ordinary 
  sediment 
  and 
  slime 
  so 
  gener- 
  

   ally 
  present 
  in 
  these 
  streams, 
  particularly 
  those 
  that 
  are 
  lake 
  fed. 
  

  

  That 
  the 
  spawning 
  beds 
  were 
  temporarily 
  injured 
  can 
  not 
  be 
  denied, 
  

   but 
  the 
  continual 
  flow 
  of 
  water 
  during 
  the 
  winter 
  w^as 
  sufficient 
  to 
  

   remove 
  most 
  of 
  the 
  objectionable 
  material. 
  This 
  fact 
  was 
  demon- 
  

   strated 
  by 
  the 
  presence 
  of 
  an 
  unusual 
  number 
  of 
  young 
  cohos 
  in 
  all 
  

   streams 
  this 
  season. 
  However, 
  from 
  examinations 
  of 
  streams 
  and 
  

   lakes 
  at 
  Seal 
  Bay, 
  Paramanoff, 
  and 
  Malena, 
  it 
  is 
  believed 
  that 
  but 
  

   comparatively 
  few 
  sockeyes 
  ascended 
  to 
  the 
  spawning 
  grounds. 
  

   Tliese 
  observations 
  were 
  made 
  the 
  latter 
  part 
  of 
  July 
  and 
  early 
  in 
  

   August, 
  after 
  the 
  run 
  was 
  practically 
  over. 
  

  

  An 
  examination 
  of 
  Letnik 
  Stream 
  was 
  made 
  from 
  May 
  to 
  July 
  

   during 
  the 
  migration 
  of 
  socke3^e 
  yearHngs 
  to 
  determine 
  the 
  effect 
  upon 
  

   young 
  salmon 
  of 
  the 
  eruption 
  of 
  Katmai 
  Volcano 
  the 
  year 
  before. 
  

   Collecting 
  stations 
  were 
  established 
  at 
  the 
  foot 
  of 
  the 
  lake 
  and 
  at 
  the 
  

   head 
  o 
  the 
  bay, 
  about 
  2 
  miles 
  below 
  where 
  the 
  stream 
  enters 
  salt 
  

   water. 
  The 
  number 
  of 
  young 
  salmon 
  collected 
  was 
  so 
  very 
  meager 
  

   as 
  to 
  justify 
  the 
  conclusion 
  that 
  there 
  had 
  been 
  a 
  heavy 
  loss, 
  due 
  no 
  

   doubt 
  to 
  the 
  fact 
  that 
  only 
  a 
  few 
  adult 
  salmon 
  reached 
  the 
  spawning 
  

   grounds 
  the 
  previous 
  season 
  when 
  the 
  eruption 
  occurred. 
  Tests 
  

   made 
  on 
  Letnik 
  I^ake 
  showed 
  that 
  there 
  is 
  now 
  an 
  ample 
  supply 
  of 
  

   the 
  small 
  form 
  of 
  crustacean 
  upon 
  which 
  young 
  salmon 
  feed. 
  

  

  The 
  project 
  of 
  stocking 
  Afognak 
  Island 
  with 
  reindeer 
  was 
  not 
  

   consummated 
  this 
  year, 
  delay 
  being 
  deemed 
  desirable 
  to 
  permit 
  of 
  

   a 
  better 
  growth 
  of 
  moss 
  following 
  its 
  destruction 
  by 
  the 
  volcanic 
  

   eruption 
  of 
  1912. 
  Under 
  normal 
  conditions, 
  Afognak 
  Island 
  should 
  

   be 
  well 
  adapted 
  to 
  the 
  propagation 
  of 
  reindeer, 
  and 
  their 
  introduction 
  

   will, 
  it 
  is 
  believed, 
  prove 
  a 
  pronounced 
  and 
  direct 
  boon 
  to 
  the 
  natives, 
  

   as 
  well 
  as 
  an 
  indirect 
  benefit 
  to 
  the 
  other 
  inhabitants 
  of 
  the 
  island. 
  

  

  Dolly 
  Varden 
  Trout. 
  

  

  A 
  noteworthy 
  catch 
  of 
  Dolly 
  Varden 
  trout 
  was 
  made 
  at 
  Paramanoff, 
  

   where 
  1,300 
  were 
  taken 
  in 
  two 
  seine 
  hauls 
  about 
  July 
  20. 
  These 
  fish 
  

   weighed 
  approximately 
  1§ 
  pounds 
  each 
  and 
  had 
  an 
  average 
  length 
  of 
  

   about 
  16 
  inches. 
  The 
  other 
  fisheries 
  produced 
  a 
  few 
  Dolly 
  Vardens 
  

   of 
  the 
  same 
  average 
  size, 
  and 
  in 
  some 
  instances, 
  particularly 
  at 
  Malena, 
  

   examples 
  were 
  taken 
  weighing 
  some 
  10 
  pounds 
  each. 
  It 
  is 
  a 
  peculiar
