  tlian 
  20 
  minutes 
  from 
  tlie 
  time 
  the 
  milt 
  is 
  applied 
  they 
  feel 
  

   like 
  shot 
  against 
  the 
  fingers, 
  and 
  to 
  an 
  experienced 
  eye 
  are 
  observed 
  

   to 
  increase 
  slightly 
  in 
  size; 
  when 
  a 
  day 
  old, 
  they 
  will 
  not 
  break 
  if 
  

   dropped 
  to 
  the 
  floor. 
  In 
  transferring 
  to 
  other 
  vessels, 
  the 
  rim 
  of 
  the 
  

   smaller 
  pan 
  should 
  be 
  gently 
  immersed 
  beneath 
  the 
  water 
  surface 
  in 
  the 
  

   larger 
  one, 
  and 
  the 
  pouring 
  take 
  place 
  gradually. 
  To 
  prevent 
  splashing, 
  

   in 
  boats, 
  a 
  small 
  j)an 
  should 
  be 
  put 
  on 
  the 
  water 
  surface 
  of 
  the 
  larger 
  

   pan. 
  Sudden 
  jars 
  must 
  be 
  avoided, 
  all 
  foreign 
  substances 
  excluded, 
  and 
  

   the 
  pans 
  be 
  free 
  from 
  grease 
  and 
  salt. 
  After 
  the 
  application 
  of 
  milt 
  

   they 
  expand 
  to 
  full 
  size 
  in 
  20 
  to 
  60 
  minutes, 
  depending 
  partly 
  on 
  tem- 
  

   perature, 
  and 
  at 
  this 
  stage 
  they 
  may 
  be 
  doubled 
  up 
  in 
  the 
  larger 
  pans, 
  the 
  

   question 
  of 
  safety 
  in 
  moving 
  them 
  being 
  determined 
  by 
  their 
  hardness. 
  

  

  Paus 
  iised 
  iu 
  cleauing 
  eggs. 
  

  

  When 
  eggs 
  are 
  received 
  at 
  the 
  station, 
  in 
  order 
  to 
  thoroughly 
  remove 
  

   all 
  impurities 
  they 
  are 
  passed 
  through 
  netting, 
  and 
  for 
  this 
  purpose, 
  

   two 
  18-inch 
  flared 
  tin 
  i)ans 
  with 
  handles, 
  one 
  pan 
  fitting 
  within 
  the 
  

   other, 
  are 
  employed; 
  2 
  inches 
  of 
  tiie 
  bottom 
  part 
  of 
  the 
  inner 
  pan 
  are 
  

   evenly 
  cut 
  off 
  and 
  replaced 
  with 
  quarter-inch 
  (bar) 
  twine 
  netting. 
  The 
  

   lower 
  pan 
  is 
  filled 
  with 
  water 
  to 
  a 
  point 
  just 
  above 
  the 
  netting, 
  and 
  

   then 
  several 
  quarts 
  of 
  eggs 
  are 
  gently 
  i)Oured 
  in.^ 
  when 
  they 
  drop 
  through 
  

   the 
  meshes, 
  leaving 
  the 
  fish 
  scales, 
  etc., 
  behind. 
  Thus 
  they 
  are 
  also 
  

   given 
  a 
  change 
  of 
  water, 
  which 
  should 
  be 
  clean 
  and 
  fresh 
  and 
  of 
  about 
  

   the 
  same 
  temperature 
  as 
  that 
  in 
  the 
  hatchery 
  and 
  river. 
  

  

  If 
  the 
  eggs 
  have 
  absorbed 
  sufficient 
  water 
  in 
  the 
  spawn-pan, 
  they 
  

   swell 
  and 
  adhere 
  to 
  each 
  other, 
  forming 
  a 
  compact 
  mass, 
  and 
  are 
  ready 
  

   to 
  be 
  transferred 
  to 
  the 
  hatching-jars, 
  but 
  if 
  they 
  are 
  not 
  sufficiently 
  

   expanded 
  or 
  '^water-hardened," 
  they 
  must 
  remain 
  in 
  the 
  pans, 
  from 
  30 
  

   to 
  60 
  minutes 
  being 
  required 
  for 
  their 
  full 
  expamsion.
