  The 
  figures~given

  Table

  are 
  based 
  on 
  actual 
  count. 
  Compared 
  

   with 
  the 
  experiments 
  of 
  1900, 
  which 
  represent 
  the 
  best 
  previous 
  efforts, 
  

   the 
  results 
  of 
  the 
  stirring 
  apparatus 
  were 
  certainly 
  satisfactory. 
  If 
  

   with 
  this 
  comparatively 
  simple 
  and 
  inexpensive 
  device 
  it 
  is 
  possible 
  to 
  

   plant 
  as 
  lobsterlings 
  20 
  per 
  cent 
  of 
  the 
  product 
  of 
  the 
  hatchery, 
  there 
  

   is 
  every 
  reason 
  to 
  believe 
  that 
  much 
  could 
  be 
  accomplished 
  for 
  a 
  

   declining 
  industr3^ 
  

  

  When 
  the 
  season's 
  work 
  was 
  planned, 
  it 
  was 
  the 
  intention 
  to 
  trans- 
  

   port 
  fry 
  for 
  the 
  experiments 
  from 
  the 
  Woods 
  Hole 
  hatchery 
  by 
  boat, 
  

   as 
  had 
  been 
  done 
  in 
  1900. 
  Circumstances 
  prevented 
  the 
  detail 
  of 
  a 
  

   proper 
  boat 
  for 
  this 
  work, 
  however, 
  and 
  it 
  was 
  necessary 
  to 
  ship 
  the 
  

   fry 
  in 
  tin 
  transportation 
  cans 
  by 
  rail, 
  a 
  journey 
  which 
  occupied 
  live 
  or 
  

   six 
  hours 
  and 
  left 
  the 
  fry 
  which 
  survived 
  the 
  trip 
  in 
  a 
  weakened 
  and 
  

   precarious 
  condition. 
  Transportation 
  thus 
  became 
  a 
  serious 
  question, 
  

   and 
  it 
  was 
  decided 
  to 
  collect 
  egg-bearing 
  female 
  lobsters 
  and 
  attempt
