  REPORT 
  OF 
  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  [122] 
  

  

  quired 
  movement 
  to 
  the 
  eggs, 
  and 
  when 
  the 
  fish 
  is 
  freed 
  from 
  its 
  shell 
  

   it 
  very 
  soon 
  is 
  caught 
  in 
  the 
  current 
  of 
  water 
  passing 
  up 
  the 
  tube, 
  and 
  

   is 
  thereby 
  transferred 
  to 
  the 
  receiver, 
  where 
  it 
  remains 
  while 
  the 
  water 
  

   passes 
  out 
  through 
  the 
  strainer. 
  As 
  the 
  eggs 
  are 
  agitated 
  by 
  the 
  cur- 
  

   rent, 
  the 
  bad 
  eggs 
  and 
  the 
  shells, 
  by 
  reason 
  of 
  their 
  less 
  specific 
  

   gravity, 
  accumulate 
  from 
  time 
  to 
  time 
  on 
  the 
  top 
  of 
  the 
  strata 
  of 
  sound 
  

   eggs. 
  Now, 
  to 
  get 
  rid 
  of 
  them 
  the 
  rubber 
  tube 
  is 
  disconnected 
  from 
  its 
  

   glass 
  tube 
  in 
  the 
  collector 
  vessel 
  and 
  its 
  glass 
  tube 
  in 
  the 
  hatching 
  

   vessel, 
  and 
  is 
  deflected 
  till 
  its 
  end 
  is 
  near 
  them, 
  when 
  the 
  induction 
  of 
  

   water 
  draws 
  off 
  these 
  eggs, 
  which 
  are 
  thrown 
  away. 
  After 
  the 
  jar 
  has 
  

   been 
  purged, 
  the 
  pipe 
  is 
  again 
  connected, 
  and 
  the 
  fish 
  are 
  allowed 
  to 
  

   pass 
  over 
  again. 
  

  

  The 
  inventor 
  says 
  : 
  

  

  " 
  I 
  am 
  aware 
  of 
  the 
  patents 
  to 
  Chase, 
  August 
  16, 
  1881, 
  and 
  Wilmot, 
  

   July 
  18, 
  1876, 
  and 
  I 
  do 
  not 
  claim 
  anything 
  shown 
  therein. 
  

  

  " 
  My 
  invention 
  is 
  distinctive 
  with 
  respect 
  to 
  processes 
  described 
  in 
  

   the 
  foregoing, 
  and 
  especially 
  the 
  Wilmot 
  process, 
  in 
  that 
  he 
  uses 
  an 
  

   open 
  vessel 
  and 
  separates 
  the 
  bad 
  eggs, 
  which 
  are 
  of 
  less 
  specific 
  

   gravity, 
  by 
  overflow 
  from 
  an 
  open 
  vessel. 
  I 
  take 
  advantage 
  of 
  the 
  

   same 
  principle 
  of 
  separating 
  the 
  bad 
  from 
  the 
  good 
  eggs 
  through 
  their 
  

   different 
  specific 
  gravities. 
  My 
  process 
  is, 
  however, 
  distinct 
  in 
  the 
  fol- 
  

   lowing 
  respects: 
  The 
  forced 
  circulation 
  in 
  a 
  closed 
  vessel, 
  and 
  dis- 
  

   charging 
  the 
  water 
  from 
  the 
  vessel 
  at 
  a 
  point 
  more 
  or 
  less 
  central 
  to 
  

   said 
  chamber 
  or 
  below 
  the 
  surface 
  of 
  the 
  water 
  enable 
  me 
  to 
  secure 
  the 
  

   following 
  important 
  results 
  : 
  First, 
  I 
  am 
  enabled 
  to 
  effect 
  the 
  separa- 
  

   tion 
  at 
  any 
  point 
  in 
  the 
  jar 
  without 
  change 
  in 
  the 
  water 
  circulation, 
  

   and 
  thus 
  can 
  treat 
  a 
  very 
  small 
  quantity 
  of 
  eggs 
  in 
  the 
  jar 
  as 
  well 
  as 
  

   if 
  the 
  jar 
  were 
  filled 
  nearly 
  to 
  the 
  top, 
  as 
  is 
  necessary 
  in 
  Wilmot's 
  in- 
  

   vention; 
  secondly, 
  I 
  avoid 
  all 
  slopping 
  over 
  of 
  the 
  water 
  in 
  the 
  jar 
  and 
  

   avoid 
  waste 
  of 
  eggs, 
  thus 
  permitting 
  my 
  process 
  to 
  be 
  conducted 
  on 
  

   cars 
  during 
  transportation 
  ; 
  thirdly, 
  by 
  taking 
  off 
  the 
  discharging 
  water 
  

   in 
  the 
  forced 
  circulation 
  at 
  a 
  point 
  more 
  or 
  less 
  central 
  to 
  the 
  jar, 
  I 
  

   avoid 
  the 
  spattering 
  of 
  the 
  water 
  and 
  damage 
  to 
  the 
  small 
  fry 
  involved 
  

   in 
  the 
  fall 
  from 
  an 
  overflowing 
  vessel 
  ; 
  and, 
  fourthly, 
  this 
  mode 
  of 
  carry- 
  

   ing 
  off 
  the 
  water 
  draws 
  the 
  eggs 
  and 
  small 
  fry 
  into 
  its 
  current 
  with 
  

   a 
  gentle 
  but 
  positive 
  suction 
  whose 
  influence 
  is 
  distributed 
  throughout 
  

   the 
  jar, 
  while 
  a 
  surface 
  overflow 
  has 
  no 
  effect 
  in 
  eliminating 
  the 
  bad 
  

   eggs 
  until 
  they 
  get 
  upon 
  the 
  immediate 
  surface. 
  

  

  CLAIMS. 
  

  

  " 
  1. 
  The 
  improved 
  process 
  of 
  automatically 
  separating 
  the 
  bad 
  eggs 
  

   and 
  small 
  fry 
  from 
  fish-eggs 
  during 
  incubation, 
  which 
  consists 
  in 
  agi- 
  

   tating 
  them 
  in 
  a 
  closed 
  chamber 
  filled 
  full 
  of 
  water 
  by 
  means 
  of 
  a 
  

   forced 
  circulation 
  of 
  the 
  same, 
  and 
  drawing 
  off 
  the 
  discharge-water 
  

   along 
  with 
  the 
  bad 
  eggs 
  or 
  small 
  fry 
  at 
  a 
  point 
  below 
  the 
  surface 
  of 
  

   the 
  water, 
  or 
  more 
  or 
  less 
  central 
  with 
  respect 
  to 
  the 
  jar, 
  as 
  described.
