  by 
  the 
  weight 
  above, 
  and 
  if 
  less 
  thau 
  five 
  trays 
  are 
  used 
  in 
  a 
  shipment 
  

   the 
  package 
  is 
  liable 
  to 
  become 
  dry, 
  and 
  the 
  eggs 
  reach 
  their 
  destina- 
  

   tion 
  either 
  dead 
  or 
  in 
  a 
  shriveled 
  condition. 
  

  

  The 
  frames 
  of 
  the 
  trays 
  are 
  made 
  of 
  light, 
  soft 
  wood 
  dressed

  with 
  a 
  soft 
  canton-flannel 
  bottom 
  tightly 
  stretched 
  and 
  

   well 
  tacked 
  on. 
  The 
  trays 
  

   are 
  made 
  large 
  enough 
  to 
  

   contain 
  their 
  proportion 
  

   of 
  the 
  eggs, 
  with 
  an 
  allow- 
  

   ance 
  of 
  5 
  of 
  an 
  inch 
  be- 
  

   tween 
  the 
  eggs 
  and 
  the 
  

   frame 
  of 
  the 
  tray. 
  A 
  foun- 
  

   dation-board 
  (B) 
  is 
  made 
  

   with 
  the 
  same 
  outside 
  di- 
  

   mensions 
  as 
  the 
  tray, 
  Avith 
  

   a 
  strip 
  nailed 
  around 
  the 
  

   edge 
  on 
  the 
  upper 
  side 
  to 
  

   form 
  a 
  cushion 
  of 
  moss 
  

   for 
  the 
  bottom 
  tray. 
  A 
  

   hopper 
  for 
  ice 
  (C) 
  is 
  used 
  

   on 
  the 
  top 
  tray. 
  The 
  out- 
  

   side 
  case 
  (E) 
  is 
  made 
  7 
  to 
  

   8 
  iuches 
  larger 
  on 
  the 
  

   sides 
  (iuside 
  measure) 
  

   and 
  5 
  inches 
  deeper 
  than 
  

   the 
  outside 
  dimensions 
  of 
  

   all 
  the 
  trays 
  after 
  they 
  

   are 
  cleated 
  together, 
  in- 
  

   cluding 
  the 
  hopper 
  and 
  

   the 
  foundation-board, 
  as 
  

   shown 
  at 
  D. 
  

  

  The 
  trays 
  having 
  been 
  

   prepared, 
  the 
  eggs 
  are 
  se 
  

   lected, 
  those 
  being 
  taken 
  

   which 
  show 
  eye-spots 
  and 
  

   are 
  not 
  too 
  old 
  to 
  reach 
  

   their 
  destination 
  before 
  

   the 
  time 
  for 
  hatching. 
  

   Allowance 
  is 
  made 
  for 
  

   changes 
  in 
  temperature 
  

   on 
  the 
  road 
  which 
  would 
  

   cause 
  them 
  to 
  hatch 
  too 
  

  

  soon.

  Egg-trays 
  packed 
  aud 
  cleated. 
  

  

  The 
  eggs 
  are 
  taken 
  from 
  the 
  hatching-trays 
  in 
  pans, 
  well 
  cleaned 
  of 
  

   all 
  sediment, 
  and 
  given 
  a 
  slight 
  concussion 
  by 
  allowing 
  water 
  to 
  fall 
  on 
  

   them 
  from 
  a 
  small 
  spout 
  or 
  sprinkling 
  pot, 
  which 
  causes 
  the 
  dead 
  and 
  

   unfertilized 
  eggs 
  to 
  turn 
  white, 
  when 
  they 
  are 
  carefully 
  removed.
