  In

  them 
  to 
  tlieir 
  destination, 
  10-gallon 
  round-shouldered 
  cans 
  

   are 
  filled 
  to 
  within 
  a 
  foot 
  of 
  the 
  top 
  with 
  the 
  water 
  used 
  in 
  hatching. 
  

   One 
  trayful, 
  or 
  2,000 
  fry, 
  is 
  put 
  in 
  each 
  can, 
  and 
  as 
  soon 
  as 
  it 
  is 
  filled, 
  

   enough 
  ice 
  is 
  added 
  to 
  bring 
  the 
  temperature 
  down 
  to 
  38° 
  or 
  40° 
  F. 
  If 
  

   the 
  fry 
  are 
  to 
  be 
  planted 
  in 
  the 
  Great 
  Lakes, 
  the 
  cans 
  are 
  transferred 
  

   from 
  the 
  car, 
  upon 
  its 
  arrival 
  at 
  its 
  destination, 
  to 
  a 
  fishing-tug 
  and 
  

   conveyed 
  to 
  the 
  reefs 
  or 
  natural 
  spawning- 
  grounds 
  of 
  the 
  lake 
  trout; 
  

   here 
  the 
  cans 
  are 
  lowered 
  into 
  the 
  water 
  and 
  the 
  fry 
  allowed 
  to 
  escape 
  

   and 
  in 
  a 
  few 
  moments 
  they 
  disappear 
  from 
  the 
  surface 
  and 
  sink 
  to 
  the 
  

   bottom. 
  

  

  PACKING 
  EYED 
  EGrGrS 
  FOR 
  SHIPMENT. 
  

  

  When 
  the 
  eye- 
  spots 
  are 
  plainly 
  visible, 
  the 
  eggs 
  can 
  be 
  j^acked 
  and 
  

   successfully 
  shipped 
  to 
  any 
  part 
  of 
  the 
  world, 
  if 
  kept 
  at 
  a 
  uniform 
  

   temperature. 
  The 
  trays 
  used 
  for 
  this 
  purpose 
  are 
  made 
  like 
  those 
  used 
  

   in 
  shipping 
  green 
  eggs 
  from 
  the 
  field 
  station 
  to 
  the 
  hatchery. 
  For 
  

   100,000 
  eggs 
  16 
  trays, 
  18 
  inches 
  by 
  18 
  inches, 
  are 
  required; 
  for 
  50,000, 
  

   8 
  trays, 
  16 
  by 
  16; 
  and 
  for 
  5,000 
  eggs, 
  5 
  trays, 
  8 
  by 
  8. 
  After 
  they 
  are 
  

   packed, 
  the 
  trays 
  are 
  i)laced 
  one 
  upon 
  the 
  other 
  and 
  crated 
  together 
  by 
  

   nailing 
  a 
  cleat 
  on 
  each 
  side 
  from 
  the 
  foundation 
  to 
  the 
  top 
  board. 
  The 
  

   packing-case 
  is 
  made 
  large 
  enough 
  to 
  admit 
  of 
  an 
  air-space 
  of 
  1 
  inches 
  

   around 
  the 
  top, 
  bottom, 
  and 
  four 
  sides 
  of 
  the 
  crate, 
  when 
  it 
  is 
  placed 
  

   in 
  position. 
  Hope 
  handles 
  are 
  inserted 
  at 
  the 
  sides. 
  

  

  The 
  temperature 
  of 
  the 
  packing-room 
  should 
  not 
  be 
  higher 
  than 
  40° 
  

   nor 
  lower 
  than 
  26°. 
  A 
  temperatnre 
  of 
  from 
  28° 
  to 
  30° 
  is 
  preferable. 
  

   The 
  canton- 
  flannel 
  trays 
  are 
  first 
  soaked 
  in 
  water, 
  drained, 
  and 
  then 
  

   placed 
  upon 
  a 
  table 
  to 
  receive 
  the 
  eggs. 
  Wooden 
  frames 
  of 
  finch 
  

   square 
  strips, 
  made 
  so 
  as 
  to 
  fit 
  inside 
  the 
  frames 
  of 
  the 
  packing-trays, 
  

   are 
  then 
  inserted. 
  A 
  box 
  of 
  eggs, 
  previously 
  picked 
  and 
  cleaned, 
  is 
  

   taken 
  out, 
  drained, 
  and 
  carried 
  to 
  the 
  packing-room. 
  The 
  eggs 
  are 
  

   carefully 
  brushed 
  from 
  the 
  wire 
  trays 
  upon 
  the 
  flannel 
  trays 
  with 
  a 
  

   feather 
  and 
  spread 
  evenly 
  over 
  the 
  surface. 
  To 
  divide 
  the 
  eggs 
  among 
  

   the 
  flannel 
  trays 
  is 
  not 
  diflicnlt, 
  as 
  there 
  are 
  40,000 
  in 
  the 
  hatching- 
  

   box, 
  or 
  4,000 
  to 
  the 
  tray. 
  The 
  inner 
  wooden 
  frame 
  is 
  now 
  removed, 
  

   leaving 
  a 
  finch 
  margin 
  on 
  all 
  sides 
  between 
  the 
  eggs 
  and 
  the 
  tray 
  

   frame, 
  and 
  a 
  piece 
  of 
  damp 
  mosquito 
  netting 
  is 
  laid 
  over 
  the 
  eggs, 
  

   extending 
  1^ 
  inches 
  beyond 
  the 
  sides 
  of 
  the 
  frame. 
  This 
  netting 
  is 
  

   pressed 
  down 
  at 
  the 
  inside 
  corners 
  of 
  the 
  tray 
  and 
  all 
  along 
  next 
  to 
  

   the 
  frame, 
  in 
  order 
  to 
  hold 
  the 
  eggs 
  in 
  position 
  and 
  avoid 
  their 
  coming 
  

   in 
  contact 
  with 
  the 
  wooden 
  frames. 
  Over 
  this 
  netting 
  is 
  scattered 
  

   sphagnum 
  moss, 
  i 
  to 
  ^ 
  of 
  an 
  inch 
  deep. 
  This 
  moss 
  is 
  gathered 
  in 
  the 
  

   fall, 
  and 
  is 
  prepared 
  by 
  being 
  soaked 
  in 
  water 
  and 
  wrung 
  out 
  with 
  a 
  

   clothes- 
  wringer. 
  It 
  must 
  be 
  free 
  from 
  all 
  sticks 
  and 
  decayed 
  matter 
  

   and 
  thoroughly 
  wrung 
  out, 
  picked 
  apart, 
  and 
  made 
  flufty, 
  for 
  if 
  used 
  

   upon 
  the 
  eggs 
  in 
  a 
  compact 
  mass, 
  the 
  supply 
  of 
  oxygen 
  would 
  not 
  be 
  

   sufidcientfor 
  their 
  maintenance 
  while 
  en 
  route. 
  It 
  should 
  be 
  moist, 
  but 
  

   not 
  so 
  wet 
  as 
  to 
  drip 
  on 
  the 
  eggs.
