  Adhesive 
  eggs 
  had 
  been 
  treated, 
  and 
  successfully, 
  before,^ 
  

   but 
  it 
  was 
  a 
  question 
  whether 
  the 
  methods 
  adopted 
  in 
  the 
  

   case 
  of 
  such 
  sjmwn 
  as 
  that 
  of 
  the 
  Carp, 
  Perch 
  and 
  Herring, 
  

   would 
  be 
  suitable 
  for 
  spawn 
  of 
  an 
  anadromoas 
  species 
  of 
  the 
  

   Salmonidce 
  family, 
  or 
  whether 
  such 
  spawn 
  should 
  be 
  treated 
  

   simply 
  as 
  the 
  non-adhesive 
  type. 
  

  

  The 
  only 
  experience 
  in 
  treating 
  Smelt 
  spawn 
  up 
  to 
  the 
  

   time 
  of 
  the 
  work 
  of 
  the 
  Commission, 
  was 
  obtained 
  by 
  Mr. 
  

   Charles 
  G. 
  Atkins, 
  of 
  Bucksport, 
  Me. 
  with 
  the 
  spawn 
  of 
  

   the 
  Land-Locked- 
  variety. 
  At 
  least 
  this 
  is 
  the 
  only 
  expe- 
  

   rience 
  cognizant 
  to 
  the 
  Commission. 
  This 
  experience 
  was 
  

   not 
  very 
  favorable 
  to 
  the 
  handling 
  of 
  this 
  species 
  of 
  adhesive 
  

   spawn, 
  and, 
  if 
  I 
  mistake 
  not, 
  Mr. 
  Atkins' 
  conclusions 
  were 
  

   that 
  it 
  would 
  not 
  pay 
  to 
  handle 
  it. 
  

  

  A 
  certain 
  amount 
  of 
  the 
  spawn 
  which 
  he 
  had, 
  hatched 
  put, 
  

   but 
  only 
  such 
  portion 
  as 
  had 
  the 
  benefit 
  of, 
  and 
  was 
  exposed 
  

   to, 
  the 
  full 
  force 
  of 
  a 
  rush 
  of 
  water 
  ; 
  in 
  fact, 
  that 
  spawn 
  only 
  

   hatched 
  which 
  remained 
  attached 
  to 
  grass, 
  twigs, 
  or 
  other 
  arti- 
  

   cles 
  situated 
  directly 
  in 
  a 
  race-way, 
  Avhere 
  the 
  water 
  rushed 
  

   along 
  very 
  furiously. 
  The 
  spawn 
  seemed 
  to 
  require, 
  at 
  least 
  

   for 
  its 
  artificial 
  culture, 
  a 
  constant 
  and 
  furious 
  change 
  of 
  

   water, 
  differing, 
  undoubtedly, 
  in 
  this 
  respect, 
  very 
  widely 
  

   from 
  its 
  requirements 
  when 
  deposited 
  by 
  the 
  fish 
  upon 
  its 
  

   natural 
  spawning 
  grounds. 
  The 
  fish 
  the 
  Commission 
  had 
  to 
  

   deal 
  with 
  were, 
  on 
  the 
  contrary, 
  anadromous, 
  and 
  we 
  had 
  no 
  

   rusJi 
  of 
  water 
  in 
  which 
  to 
  deposit 
  the 
  spawn. 
  It 
  was 
  also 
  a 
  

   question 
  whether 
  the 
  Raritan 
  Smelt 
  spawn 
  required 
  this 
  

   rushing 
  change 
  of 
  water; 
  so 
  the 
  apparatus 
  already 
  de- 
  

   scribed 
  was 
  employed 
  as 
  experimental 
  upon 
  the 
  subject. 
  

   The 
  spawn 
  was 
  carried 
  from 
  the 
  fishing 
  grounds 
  to 
  the 
  

   hatching-house 
  in 
  tin 
  dishes. 
  Sometimes, 
  but 
  rarely, 
  the 
  

   fish 
  were 
  taken 
  to 
  the 
  hatching-room, 
  and 
  there 
  spawned,
