  tinned 
  for 
  ten 
  or 
  fifteen 
  minutes, 
  the 
  plan 
  of 
  keeping 
  unripe 
  

   fish 
  in 
  a 
  reservoir 
  until 
  ripe, 
  and 
  then 
  spawning 
  them, 
  

   should 
  be 
  adopted 
  more 
  extensively 
  than 
  this 
  season. 
  

  

  They 
  should 
  he 
  kept 
  in 
  a 
  reservoir 
  separate 
  from 
  that 
  

   which 
  supplies 
  the 
  hatching 
  jars 
  with 
  water, 
  since 
  the 
  fish 
  

   are 
  apt 
  to 
  be 
  drawn 
  against 
  the 
  openings 
  into 
  the 
  supply 
  

   pipes 
  for 
  the 
  jars 
  and 
  the 
  water 
  thus 
  cutoff 
  from 
  the 
  spawn, 
  

   and 
  stagnant 
  water 
  Itivors 
  fungoid 
  growths. 
  They 
  should 
  

   also 
  be 
  examined 
  carefully 
  each 
  day, 
  so 
  that 
  as 
  soon 
  as 
  ripe 
  

   the 
  spawn 
  and 
  milt 
  may 
  be 
  taken 
  from 
  them, 
  and 
  yet 
  not 
  

   taken 
  from 
  them 
  until 
  they 
  are 
  fully 
  ripe. 
  In 
  this 
  manner 
  

   a 
  large 
  quantity 
  of 
  spawn 
  should 
  be 
  obtained, 
  and 
  unless 
  the 
  

   fish 
  are 
  injured 
  there 
  is 
  no 
  reason, 
  so 
  far 
  as 
  at 
  present 
  known, 
  

   why 
  such 
  spawn 
  should 
  not 
  turn 
  out 
  as 
  well 
  at 
  that 
  of 
  Trout 
  

   kept 
  in 
  a 
  similar 
  manner. 
  Spawn 
  taken 
  from 
  fish 
  thus 
  

   kept 
  sliould 
  be 
  placed 
  separate 
  from 
  that 
  of 
  spawn 
  from 
  

   fish 
  taken 
  fresh 
  from 
  tht; 
  river, 
  and 
  the 
  two 
  carefully 
  com- 
  

   pared, 
  after, 
  of 
  course, 
  the 
  same 
  manipulation, 
  so 
  as 
  to 
  see 
  

   which 
  method 
  is 
  the 
  better 
  ; 
  records, 
  of 
  course, 
  being 
  kopt 
  

   of 
  each. 
  In 
  making 
  this 
  experiment 
  the 
  largest 
  fish 
  shoiild 
  

   be 
  kept 
  as 
  furnishing 
  so 
  many 
  more 
  eggs, 
  or 
  so 
  much 
  more 
  

   milt 
  than 
  the 
  small 
  ones. 
  But 
  to 
  carrj^ 
  out 
  this 
  experiment, 
  

   more 
  room 
  will 
  be 
  required 
  than 
  was 
  at 
  the 
  service 
  of 
  the 
  

   Commission 
  this 
  season, 
  and 
  it 
  would 
  undoubtedly 
  be 
  better 
  

   if 
  accommodations 
  of 
  sufficient 
  size 
  could 
  be 
  secured 
  near 
  

   the 
  fishing 
  grounds, 
  so 
  as 
  to 
  obviate 
  as 
  much 
  as 
  possible 
  

   the 
  transfer 
  or 
  carriage 
  of 
  fish 
  and 
  spawn. 
  The 
  treatment 
  

   of 
  the 
  eggs, 
  after 
  they 
  are 
  placed 
  in 
  the 
  jars, 
  does 
  not 
  difier 
  

   materially 
  from 
  that 
  of 
  other 
  spawn. 
  A 
  constant 
  flow 
  of 
  

   water, 
  and 
  since 
  the 
  eggs 
  adhere 
  to 
  their 
  support, 
  a 
  much 
  

   stronger 
  flow 
  through 
  the 
  jars, 
  can 
  be 
  permitted, 
  than 
  with 
  

   other 
  eggs 
  ; 
  clean 
  jars 
  and 
  trays 
  ; 
  and 
  the 
  removal 
  of 
  dead 
  

   eggs. 
  The- 
  removal 
  of 
  dead 
  eggs, 
  in 
  the 
  case 
  of 
  the 
  Smelt 
  

   spawn, 
  is 
  almost 
  practically 
  impossible, 
  on 
  account 
  of 
  the 
  

   adherence 
  of 
  the 
  eggs 
  to 
  each 
  other, 
  as 
  well 
  as 
  to 
  the 
  sup-
