  inches; 
  the 
  sides 
  and 
  ends 
  are 
  1-inch 
  pine 
  and 
  the 
  bottoms 
  ^ 
  inch-mesh 
  

   iron 
  wire 
  cloth, 
  which 
  is 
  continued 
  over 
  the 
  rounded 
  ends. 
  Cleats 
  are 
  

   nailed 
  on 
  the 
  sides, 
  one 
  end 
  somewhat 
  lower 
  than 
  the 
  other, 
  to 
  give 
  the 
  

   box 
  a 
  tilt 
  when 
  placed 
  in 
  water. 
  Each 
  box 
  carries 
  safely 
  about 
  180,000 
  

   eggs, 
  and 
  when 
  it 
  is 
  filled 
  is 
  anchored 
  either 
  in 
  running 
  water 
  or 
  in 
  a 
  

   sheltered 
  cove 
  of 
  the 
  lake. 
  In 
  the 
  former 
  case 
  a 
  current 
  of 
  water 
  is 
  

   kept 
  passing 
  through 
  the 
  box, 
  while 
  in 
  the 
  latter 
  tbe 
  eggs 
  are 
  given 
  a 
  

   slight 
  motion 
  by 
  the 
  action 
  of 
  the 
  waves 
  upon 
  the 
  surface 
  of 
  the 
  water. 
  

  

  Floating-box. 
  

  

  When 
  eggs 
  held 
  in 
  floating-boxes 
  are 
  to 
  be 
  shipped 
  they 
  are 
  dipped 
  

   into 
  pails 
  and 
  taken 
  to 
  a 
  place 
  arranged 
  for 
  packing 
  them, 
  located 
  

   at 
  no 
  great 
  distance 
  away, 
  where 
  a 
  table 
  upon 
  which 
  to 
  place 
  the 
  

   trays 
  may 
  be 
  improvised 
  from 
  any 
  material 
  at 
  hand. 
  

  

  The 
  trays 
  for 
  packing 
  the 
  eggs 
  are 
  constructed 
  by 
  making 
  a 
  frame 
  of 
  

   |-inch 
  square 
  pine, 
  18 
  inches 
  square, 
  inside 
  measurement, 
  with 
  white 
  

   canton 
  flannel 
  tacked 
  on 
  one 
  side. 
  A 
  case 
  to 
  contain 
  the 
  trays 
  is 
  made 
  

   of 
  4-inch 
  pine, 
  large 
  enough 
  to 
  hold 
  19 
  of 
  these 
  trays 
  one 
  over 
  the 
  other, 
  

   allowing 
  for 
  a 
  surrounding 
  air-space 
  of 
  half 
  an 
  inch. 
  Half-inch 
  cleats 
  

   are 
  nailed 
  on 
  the 
  bottom 
  and 
  at 
  the 
  corners 
  of 
  the 
  box 
  on 
  the 
  inside, 
  so 
  

   that 
  the 
  trays 
  are 
  securely 
  held 
  in 
  position. 
  A 
  hinged 
  door 
  is 
  at 
  the 
  top, 
  

   handles 
  are 
  at 
  the 
  sides, 
  and 
  the 
  whole 
  is 
  painted 
  and 
  of 
  neat 
  appearance. 
  

  

  For 
  transferring 
  the 
  eggs 
  from 
  pail 
  to 
  tray 
  a 
  graduated 
  dipper 
  is 
  

   used, 
  which 
  has 
  a 
  capacity 
  of 
  about 
  10,000 
  eggs, 
  the 
  number 
  usually 
  

   placed 
  upon 
  each 
  tray. 
  Thus, 
  in 
  a 
  case 
  containing 
  18 
  trays 
  180,000 
  

   eggs 
  may 
  be 
  stored. 
  A 
  dipperful 
  is 
  placed 
  upon 
  each 
  tray. 
  The 
  canton 
  

   flannel 
  holds 
  water 
  for 
  some 
  time, 
  and 
  if 
  a 
  little 
  is 
  poured 
  upon 
  the 
  

   eggs, 
  which 
  are 
  at 
  first 
  bunched 
  in 
  the 
  center, 
  they 
  settle 
  and 
  spread, 
  

   and 
  by 
  a 
  slight 
  dexterous 
  movement, 
  acquired 
  by 
  practice, 
  are 
  evenly 
  

   divided 
  over 
  the 
  tray. 
  Ten 
  thousand 
  eggs 
  on 
  a 
  surface 
  18 
  inches 
  by 
  18 
  

   inches 
  are 
  about 
  two 
  deep, 
  and 
  if 
  kept 
  at 
  the 
  proper 
  temperature 
  and 
  

   handled 
  carefully 
  they 
  may 
  be 
  carried 
  a 
  long 
  distance. 
  After 
  the 
  eggs
