  These 
  frames 
  I 
  woiild 
  then 
  have 
  

   arrangfMl 
  in 
  lines 
  or 
  series 
  with 
  wooden 
  floats, 
  moored 
  

   close 
  to 
  an 
  oyster 
  bank, 
  in 
  order 
  that 
  the 
  floating 
  embryos 
  

   from 
  these 
  banks 
  might 
  the 
  more 
  readily 
  And

   the 
  surfaces 
  of 
  the 
  frames 
  to 
  flx 
  themselves. 
  

  

  Floating 
  shingles 
  thinly 
  coated 
  with 
  cement 
  as 
  a 
  pro- 
  

   tection 
  against 
  the 
  ship-worm, 
  fastened 
  together 
  with 
  

   wire 
  so 
  as 
  to 
  form 
  large 
  squares, 
  might 
  also 
  be 
  used 
  in 
  

   the 
  same 
  situations 
  with 
  good 
  results. 
  The 
  ship-worm 
  

   might 
  be 
  allowed 
  to 
  destroy 
  the 
  sliingles 
  as 
  they 
  Avould 
  

   still 
  answer 
  the 
  purpose 
  long 
  encmgh 
  to 
  allow 
  the 
  "'spat" 
  

   to 
  acquire 
  a 
  considera))le 
  size, 
  and 
  afterwards 
  be 
  easily 
  

   broken 
  u]) 
  when 
  it 
  became 
  desirable 
  to 
  use 
  the 
  ''spat" 
  

   in 
  the 
  "nuiseries'' 
  or 
  as 
  "plants." 
  But 
  such 
  n 
  ])ractice 
  

   if 
  long 
  continued 
  might 
  prove 
  disadvantageous, 
  iiiasmuch 
  

   as 
  the 
  cultivation 
  of 
  the 
  ship-worm 
  would 
  also 
  ))e 
  effect- 
  

   ed, 
  a 
  business 
  not 
  i\t 
  all 
  profltable 
  where 
  other 
  sulmierged 
  

   wooden 
  structures 
  were 
  in 
  use 
  which 
  it 
  Avas 
  desirable 
  to 
  

   protect 
  from 
  this 
  destructive 
  creature. 
  

  

  The 
  only 
  advantages 
  to 
  be 
  secured 
  by 
  the 
  use 
  of 
  float- 
  

   ing 
  (Y)llectors 
  would 
  be 
  in 
  providing 
  a 
  means 
  for 
  floating 
  

   embryos 
  to 
  flx 
  themselves. 
  Whether 
  the 
  free 
  swimming 
  

   embr^^o 
  oysters 
  will 
  really 
  nflix 
  themselves 
  more 
  freely 
  

   to 
  a 
  floating 
  apparatus 
  can 
  of 
  course 
  only 
  be 
  determined 
  

   by 
  experiment. 
  At 
  times 
  it 
  seemed 
  to 
  me 
  that 
  the 
  col- 
  

   lectors 
  which 
  had 
  been 
  placed 
  nearest 
  the 
  surface 
  had 
  

   caught 
  the 
  most 
  fry, 
  in 
  other 
  cases 
  this 
  seemed 
  not 
  to 
  be 
  

   the 
  case. 
  There 
  remains 
  enough 
  evidence 
  howevei* 
  to 
  

   make 
  it 
  desirable 
  that 
  this 
  plan 
  should 
  be 
  thoroughly 
  

   tested. 
  

  

  THE 
  UOX-COLLECTOK. 
  

  

  The 
  box-collector 
  in 
  use 
  in 
  France 
  is 
  a 
  rough 
  box 
  

   three 
  feet 
  wide, 
  six 
  long 
  and 
  two 
  and 
  a 
  half 
  deex> 
  ; 
  it 
  is 
  

   provided 
  inside 
  with 
  a 
  tier 
  of 
  three 
  trays 
  at 
  each 
  end 
  

   nearly 
  three 
  feet 
  square 
  ; 
  upon 
  these 
  trays 
  are 
  placed 
  

   dead 
  oystei' 
  shells 
  and 
  a 
  lew 
  live, 
  spawning 
  oysters. 
  

   This 
  was 
  essentially 
  the 
  form 
  used 
  by 
  me 
  in 
  my 
  experi-
