  This 
  device 
  is 
  analogous 
  to 
  the 
  well 
  known 
  " 
  Williamson 
  hatching 
  

   trough," 
  but 
  differs 
  from 
  it 
  in 
  construction, 
  whereby 
  it 
  can 
  be 
  readily 
  

   taken 
  apart 
  and 
  folded 
  into 
  a 
  small 
  compass 
  for 
  package 
  or 
  transporta- 
  

   tion. 
  Instead 
  of 
  having 
  the 
  sides 
  and 
  bottom 
  of 
  solid 
  wood 
  they 
  are 
  of 
  

   light 
  water-proof 
  fabric 
  or 
  cloth 
  stretched, 
  laid, 
  and 
  fastened 
  on 
  longi- 
  

   tudinal 
  bars 
  connecting 
  the 
  wooden 
  ends 
  and 
  partitions 
  of 
  the 
  trough, 
  

   and 
  confined 
  thereto 
  by 
  cleats 
  and 
  screws. 
  Each 
  partition 
  has 
  a 
  pas- 
  

   sage 
  through 
  it 
  and 
  is 
  open 
  laterally 
  at 
  top 
  and 
  bottom. 
  Egg-hatching 
  

   trays 
  are 
  placed 
  in 
  its 
  several 
  larger 
  compartments. 
  The 
  water 
  passing 
  

   into 
  the 
  trough 
  at 
  one 
  end 
  flows 
  from 
  one 
  compartment 
  to 
  the 
  other 
  

   and 
  upward 
  through 
  each 
  series 
  of 
  trays 
  and 
  escapes 
  at 
  the 
  other 
  end 
  

   of 
  the 
  trough, 
  which 
  is 
  notched, 
  to 
  allow 
  the 
  water 
  to 
  pass 
  off 
  at 
  a 
  

   proper 
  level.
