  the 
  young 
  have 
  grown 
  to 
  be 
  I 
  to 
  2 
  of 
  an 
  inch 
  in 
  diameter 
  

   they 
  woukl 
  probably 
  thrive 
  better 
  in 
  a 
  cage 
  made 
  of 
  wire 
  

   cloths 
  with 
  coarser 
  meshes. 
  Here 
  they 
  should 
  be 
  spread 
  

   upon 
  trays 
  so 
  as 
  not 
  to 
  encroach 
  upon 
  one 
  another, 
  but 
  

   the 
  care 
  to 
  keep 
  them 
  from 
  being 
  injured 
  by 
  other 
  

   growths 
  and 
  enemies 
  should 
  not 
  be 
  abated. 
  Finally, 
  

   after 
  being 
  cared 
  for 
  until 
  a 
  few 
  months 
  old 
  they 
  would 
  

   probably 
  be 
  ready 
  to 
  be 
  introduced 
  into 
  the 
  claires 
  or 
  

   parks, 
  where 
  a 
  clean 
  l)ottom 
  should 
  be 
  prepared 
  for 
  them 
  

   upon 
  which 
  they 
  should 
  be 
  spread, 
  so 
  as 
  not 
  to 
  interfere 
  

   with 
  each 
  others 
  growth 
  by 
  being 
  crowded 
  too 
  thickly 
  

   together 
  on 
  the 
  bottom. 
  

  

  The 
  difficulties 
  about 
  the 
  methods 
  Just 
  proposed, 
  are 
  

   tlieir 
  practicability 
  and 
  cheapness 
  which 
  may 
  be 
  found 
  

   to 
  be 
  insurmountal)le 
  obstacles 
  in 
  the 
  way 
  of 
  their 
  suc- 
  

   cess 
  upon 
  being 
  brought 
  into 
  practice. 
  And, 
  I 
  have 
  

   only 
  taken 
  uj) 
  so 
  much 
  space 
  with 
  a 
  description 
  of 
  my 
  

   plans 
  in 
  order 
  that 
  some 
  one 
  else 
  may 
  be 
  able 
  to 
  test 
  

   them 
  should 
  T 
  be 
  prevented 
  from 
  doing 
  so, 
  as 
  well 
  as 
  to 
  

   point 
  out 
  a 
  new 
  line 
  of 
  experiment 
  looking 
  to 
  the 
  solu- 
  

   tion 
  of 
  the 
  difficult 
  problem 
  of 
  the 
  cheap 
  and 
  practical 
  

   artificial 
  cultivaticm 
  of 
  our 
  noble 
  American 
  oyster. 
  

  

  OHSEKVA'l'IOXS 
  AS 
  TO 
  THE 
  SIZP: 
  OF 
  THE 
  FKY 
  AT 
  THE 
  TIME 
  

   OF 
  FIXATION. 
  

  

  Upon 
  examining 
  the 
  hinge 
  of 
  young 
  oysters 
  carefully, 
  

   it 
  will 
  be 
  noticed 
  that 
  at 
  the 
  very 
  apex 
  of 
  the 
  umbo 
  of 
  

   either 
  valve 
  there 
  is 
  a 
  very 
  small 
  rounded 
  prominence. 
  

   Tliis 
  up(m 
  examination 
  with 
  a 
  magnifying 
  power 
  of 
  fifty 
  

   diameters 
  is 
  found 
  to 
  show 
  faint 
  lines 
  of 
  growth 
  like 
  the 
  

   other 
  portions 
  of 
  the 
  shell. 
  It 
  covers 
  like 
  a 
  little 
  cap 
  

   the 
  extreme 
  tip 
  of 
  the 
  valve 
  and 
  apjjears 
  to 
  be 
  sojuewhat 
  

   raised 
  from 
  the 
  other 
  pait 
  of 
  the 
  shell 
  oi- 
  mai'ked 
  off 
  by 
  

   a 
  groove 
  which 
  surrounds 
  it. 
  On 
  compaiing 
  a 
  great 
  

   number 
  of 
  young 
  spat 
  we 
  always 
  found 
  these 
  little 
  cap- 
  

   like 
  tips 
  to 
  the 
  valves, 
  and 
  always 
  of 
  about 
  the 
  same 
  

   size 
  and 
  shape.
