  the 
  Fortmann 
  hatchery, 
  the 
  take 
  of 
  18,400,000 
  eggs 
  was 
  better 
  than 
  

   ever 
  before. 
  

  

  On 
  the 
  theory 
  that 
  most 
  of 
  the 
  red 
  salmon 
  in 
  Alaska 
  return 
  when 
  

   5 
  years 
  old, 
  some 
  interesting 
  comparisons 
  are 
  possible 
  by 
  going 
  back 
  

   a 
  few 
  years 
  in 
  the 
  record 
  of 
  eggs 
  taken 
  at 
  the 
  Fortmann 
  hatchery. 
  

   In 
  1906 
  the 
  take 
  was 
  105,000,000 
  eggs, 
  while 
  five 
  years 
  later 
  in 
  1911 
  

   it 
  was 
  107,000,000. 
  The 
  1907 
  take 
  was 
  41,000,000 
  and 
  that 
  of 
  1912 
  

   was 
  23,000,000. 
  In 
  1908 
  the 
  take 
  was 
  24,000,000 
  and 
  1913 
  produced 
  

   but 
  9,000,000 
  eggs. 
  Round 
  figures 
  only 
  are 
  given. 
  

  

  Thus 
  it 
  will 
  be 
  seen 
  that 
  there 
  is 
  a 
  much 
  more 
  pronounced 
  corollary 
  

   in 
  the 
  five-year 
  cycles 
  than 
  in 
  the 
  four-year 
  periods. 
  If 
  the 
  five- 
  

   year 
  cycle 
  theory 
  is 
  a 
  correct 
  index, 
  as 
  it 
  seems 
  to 
  be, 
  a 
  light 
  take 
  was 
  

   to 
  be 
  expected 
  for 
  1913, 
  since 
  1908 
  was 
  a 
  poor 
  season, 
  comparatively 
  

   speaking. 
  Carrying 
  this 
  reasoning 
  to 
  future 
  years, 
  1914 
  ought 
  to 
  be 
  

   better, 
  as 
  the 
  1909 
  take 
  was 
  53,000,000; 
  then 
  might 
  come 
  a 
  poorer 
  

   take 
  in 
  1915, 
  as 
  the 
  1910 
  collection 
  dropped 
  to 
  34,000,000. 
  Then 
  in 
  

   1916 
  should 
  come 
  a 
  heavy 
  run, 
  for 
  in 
  1911, 
  five 
  years 
  before, 
  the 
  take 
  

   was 
  107,000,000, 
  whUe 
  in 
  1906, 
  another 
  five-year 
  cycle 
  back, 
  the 
  

   take 
  was 
  105,000,000. 
  These 
  figures 
  certainly 
  form 
  the 
  basis 
  for 
  

   interesting 
  speculation, 
  both 
  as 
  to 
  the 
  take 
  of 
  eggs 
  at 
  the 
  hatcheries 
  

   and 
  the 
  runs 
  of 
  red 
  salmon 
  that 
  may 
  be 
  anticipated 
  by 
  the 
  cannery- 
  

   men.

  At 
  the 
  Karluk 
  hatchery 
  of 
  the 
  Alaska 
  Packers' 
  Association, 
  located 
  

   on 
  Kodiak 
  Island, 
  the 
  season 
  of 
  1912-13 
  was 
  productive 
  of 
  45,600,000 
  

   red-salmon 
  eggs, 
  from 
  which 
  in 
  1913 
  a 
  total 
  of 
  41,803,155 
  free-swim- 
  

   ming 
  fry 
  were 
  liberated 
  in 
  the 
  Karluk 
  River. 
  The 
  loss 
  was 
  thus 
  8J 
  

   per 
  cent. 
  The 
  1913-14 
  season 
  resulted 
  in 
  a 
  take 
  of 
  34,629,160 
  red- 
  

   salmon 
  eggs, 
  the 
  period 
  of 
  collection 
  extending 
  from 
  June 
  21 
  to 
  Octo- 
  

   ber 
  11. 
  Each 
  female 
  produced 
  on 
  the 
  average 
  3,109 
  eggs.

  Egg 
  taking 
  for 
  the 
  season 
  of 
  1912-13 
  at 
  the 
  Quadra 
  Lake 
  hatchery 
  

   began 
  August 
  16 
  and 
  was 
  completed 
  November 
  12, 
  1912. 
  From 
  3,135 
  

   females 
  there 
  were 
  obtained 
  10,000,000 
  eggs, 
  an 
  average 
  of 
  3,190 
  per 
  

   fish. 
  The 
  eggs 
  eyed 
  in 
  from 
  42 
  to 
  55 
  days 
  and 
  the 
  hatching 
  period 
  

   varied 
  from 
  111 
  to 
  135 
  days. 
  Water 
  temperatures 
  ranged 
  between 
  

   36° 
  and 
  42° 
  F. 
  From 
  the 
  take 
  of 
  10,000,000 
  eggs 
  a 
  total 
  of 
  8,127,000 
  

   fry 
  resulted. 
  The 
  first 
  plant 
  occurred 
  December 
  7 
  and 
  the 
  last 
  April 
  7. 
  

   A 
  total 
  of 
  7,000,000 
  fry 
  were 
  liberated 
  in 
  the 
  three 
  ponds 
  adjoining 
  

   the 
  hatchery, 
  897,000 
  went 
  into 
  the 
  hatchery 
  creek 
  and 
  the 
  remain- 
  

   ing 
  230,000 
  were 
  carried 
  overland 
  to 
  a 
  stream 
  tributary 
  to 
  Marten 
  

   Arm. 
  

  

  An 
  interesting 
  fact 
  in 
  connection 
  with 
  the 
  take 
  of 
  eggs 
  is 
  that 
  out 
  

   of 
  the 
  2,145,000 
  eggs 
  taken 
  from 
  August 
  16 
  to 
  September
