﻿them 
  for 
  this 
  purpose 
  are 
  quite 
  unHke 
  the 
  favorite 
  spawning 
  

   grounds 
  of 
  the 
  shad. 
  Whereas 
  the 
  shad 
  prefer 
  the 
  open 
  

   waters 
  or 
  extensive 
  tiats, 
  the 
  lierring 
  seek 
  shoal 
  places 
  where 
  

   can 
  be 
  found 
  quantities 
  of 
  aquatic 
  plants 
  and 
  sticks 
  to 
  which 
  

   their 
  eggs 
  are 
  attached. 
  Such 
  localities 
  are 
  generally 
  out 
  of 
  

   the 
  line 
  of 
  operations 
  of 
  fishermen, 
  using 
  either 
  haul 
  seines 
  

   or 
  gill 
  nets, 
  implements 
  which 
  readily 
  capture 
  the 
  shad 
  on 
  

   their 
  more 
  exposed 
  spawning 
  grounds. 
  Thus 
  we 
  can, 
  at 
  the 
  

   same 
  time, 
  account 
  for 
  the 
  continued 
  comparative 
  abundance 
  

   of 
  herring, 
  while 
  the 
  decrease 
  of 
  shad 
  has 
  been 
  so 
  alarming, 
  

   and 
  also 
  for 
  the 
  failure 
  to 
  find 
  ripe 
  herring 
  among 
  the 
  masses 
  

   which 
  are 
  landed 
  at 
  every 
  haul 
  of 
  the 
  large 
  seines. 
  

  

  "While 
  conducting 
  the 
  joint 
  shad 
  hatching 
  work 
  of 
  the 
  Ma- 
  

   ryland 
  and 
  tlie 
  United 
  States 
  Commissions 
  on 
  Albermarle 
  

   Sound 
  in 
  North 
  Carolina 
  during 
  last 
  spring, 
  we 
  succeeded 
  in 
  

   securing 
  near 
  the 
  head 
  waters 
  of 
  a 
  creek 
  flowing 
  into 
  the 
  

   sound, 
  called 
  Salmon 
  Creek, 
  a 
  number 
  of 
  ripe 
  herring, 
  from 
  

   which 
  we 
  obtained 
  many 
  hundreds 
  of 
  thousands 
  of 
  eggs. 
  

   These 
  were 
  treated 
  in 
  a 
  manner 
  very 
  similar 
  to 
  that 
  pursued 
  

   with 
  the 
  shad 
  eggs, 
  and 
  they 
  were 
  placed 
  in 
  one 
  of 
  the 
  shad 
  

   hatching 
  cylinders 
  referred 
  to. 
  Although 
  at 
  first 
  these 
  eggs 
  are 
  

   very 
  adhesive, 
  and 
  have 
  to 
  be 
  handled 
  with 
  great 
  care, 
  they 
  soon 
  

   become 
  somewhat 
  free 
  and 
  can 
  be 
  hatched 
  very 
  readily. 
  It 
  

   has 
  been 
  demonstrated 
  that 
  as 
  the 
  necessity 
  arises 
  for 
  the 
  in- 
  

   crease 
  of 
  herring 
  by 
  artificial 
  means, 
  they 
  can 
  be 
  successfully 
  

   propagated, 
  although 
  requiring 
  the 
  selection 
  of 
  other 
  locali- 
  

   ties 
  than 
  tliose 
  which 
  have 
  proved 
  so 
  favorable 
  to 
  shad 
  culture. 
  

   We 
  deem 
  it 
  of 
  some 
  importance 
  to 
  have 
  established 
  the 
  fact 
  

   that 
  the 
  herring 
  can 
  be 
  propagated 
  artificially 
  and 
  in 
  large 
  

   numbers, 
  as 
  the 
  necessity 
  for 
  this 
  work 
  will 
  soon 
  arise 
  if 
  in- 
  

   deed 
  it 
  does 
  not 
  already 
  exist 
  in 
  some 
  localities. 
  

  

  The 
  large 
  increase 
  in 
  the 
  results 
  obtained 
  in 
  our 
  shad 
  hatch- 
  

   ing 
  operations 
  was 
  a 
  consequence 
  of 
  the 
  improvement 
  and 
  

   perfection 
  of 
  our 
  apparatus. 
  During 
  the 
  year 
  1878 
  9,820,000 
  

   of 
  shad 
  were 
  hatched 
  and 
  distributed.
