  the

  iuetinct 
  wliicli 
  has 
  been 
  so 
  clearly 
  dem- 
  

   onstrated 
  as 
  governing 
  the 
  Salmon. 
  Such 
  unmistakable 
  

   evidence 
  have 
  we 
  in 
  the 
  capture 
  of 
  several 
  hundred 
  adult 
  

   white 
  Shad, 
  Alosa 
  sapidisima, 
  in 
  the 
  Ohio 
  river 
  last 
  spring, 
  

   since 
  jDrior 
  to 
  their 
  introduction 
  in 
  1872, 
  by 
  the 
  United 
  States 
  

   Commissioner, 
  this 
  most 
  valuable 
  fish 
  was 
  unknown 
  to 
  the 
  

   Mississippi 
  river, 
  or 
  any 
  oi' 
  its 
  tributaries. 
  Add 
  to 
  this 
  the 
  

   successful 
  introduction 
  of 
  Shad 
  into 
  the 
  rivers 
  of 
  the 
  Pacific 
  

   slope, 
  and 
  we 
  afe 
  forced 
  to 
  the 
  conviction 
  that 
  the 
  same 
  

   laws 
  are 
  applicable 
  to 
  the 
  return 
  of 
  the 
  Shad 
  as 
  to 
  the 
  Sal- 
  

   mon, 
  viz 
  : 
  that 
  they 
  will 
  return 
  as 
  adult 
  to 
  the 
  waters 
  in 
  

   which 
  they 
  are 
  placed 
  when 
  young.

  report 
  of 
  the 
  Commissioners 
  of 
  Fish- 
  

   eries 
  of 
  the 
  State 
  of 
  California 
  for 
  '76 
  and 
  '77, 
  they 
  say 
  : 
  

   '' 
  Shad, 
  in 
  their 
  season, 
  are 
  becoming 
  quite 
  numerous 
  in 
  tlie 
  

   Sacramento 
  river. 
  The 
  experiment 
  of 
  their 
  importation 
  to 
  

   this 
  coast 
  has 
  resulted 
  satisfiictorily. 
  The 
  river 
  is 
  of 
  proper 
  

   temperature, 
  ami 
  furnishes 
  an 
  abundance 
  of 
  food 
  for 
  the 
  

   young 
  fish 
  before 
  they 
  go 
  to 
  the 
  ocean. 
  There 
  can 
  be 
  no 
  

   doubt 
  that 
  the 
  first 
  Shad 
  brought 
  from 
  the 
  Hudson 
  river, 
  in 
  

   eighteen 
  hundred 
  and 
  seventy-one, 
  have 
  been 
  to 
  tlie 
  ocean, 
  

   returned 
  and 
  spawned." 
  

  

  The 
  introduction 
  of 
  Shad 
  into 
  the 
  rivers 
  flowing 
  into 
  llu 
  

   great 
  lakes 
  has 
  also 
  proved 
  as 
  completely 
  successful, 
  although 
  

   it 
  was 
  feared 
  that 
  they 
  would 
  not 
  find 
  in 
  the 
  fresh 
  waters 
  of 
  

   the 
  lakes, 
  conditions 
  as 
  suitable 
  as 
  in 
  the 
  salt 
  water 
  of 
  their 
  

   accustomed 
  abode 
  in 
  the 
  Atlantic. 
  During 
  the 
  past 
  season, 
  

   many 
  fine 
  large 
  specimens, 
  weighing 
  as 
  much 
  as 
  five 
  and 
  a 
  

   half 
  pounds, 
  were 
  taken 
  in 
  the 
  tributaries 
  of 
  Lake 
  Ontario. 
  

   The 
  dates 
  of 
  the 
  original 
  deposit 
  of 
  the 
  young 
  fish 
  in 
  the 
  

   waters 
  in 
  which 
  they 
  had 
  hitherto 
  been 
  unknown, 
  and 
  the 
  

   times 
  of 
  their 
  subsequent 
  re-appearance 
  as 
  adult, 
  give 
  U8 
  

   some 
  evidence, 
  also 
  of 
  the 
  probable 
  growth, 
  of 
  the 
  variety 
  of 
  

   fish. 
  In 
  these 
  instances 
  of 
  the 
  successful 
  introduction 
  of 
  Shad 
  

   in 
  California, 
  in 
  the 
  Ohio 
  and 
  in 
  the 
  Great 
  Lakes, 
  the 
  first 
  

   deposits 
  having 
  been

  1871,
