  CERTAIN 
  PLANTING

  1. 
  — 
  The 
  first 
  planting 
  was 
  made 
  April 
  26, 
  1900, 
  with 
  -ll 
  

   bushels 
  of 
  shells 
  arranged 
  in 
  five 
  rows 
  across 
  the 
  current. 
  This 
  570 
  

   square 
  feet 
  of 
  stiff 
  deep 
  mud, 
  into 
  which 
  an 
  oar 
  can 
  be 
  thrust 
  to 
  a 
  

   depth 
  of 
  15 
  inches, 
  is 
  covered 
  at 
  low 
  tide 
  with 
  3^ 
  feet 
  of 
  water. 
  Dur- 
  

   ing 
  the 
  first 
  summer 
  an 
  immense 
  number 
  of 
  spat 
  attached 
  to 
  the 
  shells, 
  

   many 
  of 
  which 
  on 
  the 
  Gth 
  of 
  August 
  measured 
  nearly 
  two 
  inches 
  in 
  

   length. 
  The 
  number 
  dead 
  or 
  killed 
  during 
  the 
  first 
  season 
  was 
  also 
  

   large, 
  being 
  about 
  two-fifths 
  of 
  the 
  total 
  nmnber 
  that 
  attached 
  to 
  the 
  

   shells. 
  Of 
  those 
  found 
  dead 
  on 
  August 
  6, 
  about 
  three-fifths 
  were 
  

   smothered 
  by 
  mud 
  and 
  the 
  remainder 
  were 
  killed 
  by 
  "drills" 
  {Uro- 
  

   saljnnx 
  cinerea)^ 
  as 
  was 
  shown 
  b}' 
  the 
  small 
  round 
  hole 
  in 
  the 
  shells. 
  

   The 
  number 
  of 
  living 
  oysters 
  found 
  on 
  June 
  3, 
  1901, 
  was 
  a 
  little 
  less 
  

   than 
  half 
  the 
  number 
  present 
  at 
  the 
  time 
  of 
  the 
  previous 
  examination. 
  

   Very 
  few 
  were 
  larger 
  than 
  those 
  found 
  on 
  August 
  6, 
  so 
  that 
  either 
  

   little 
  growth 
  had 
  taken 
  place 
  or 
  the 
  first 
  catch 
  had 
  practical 
  h^ 
  all 
  

   died 
  and 
  a 
  new 
  lot 
  had 
  become 
  attached. 
  During 
  June 
  and 
  July, 
  

   a 
  rapid 
  growth 
  took 
  place 
  and 
  an 
  enormous 
  number 
  of 
  additional 
  spat 
  

   were 
  caught; 
  but 
  toward 
  the 
  end 
  of 
  July 
  and 
  the 
  first 
  of 
  August 
  

   every 
  oyster 
  died. 
  On 
  August 
  18, 
  when 
  the 
  regular 
  examination 
  

   was 
  made, 
  640 
  dead 
  oysters 
  were 
  counted 
  on 
  100 
  shells, 
  many 
  of 
  

   them 
  with 
  the 
  hinge 
  of 
  their 
  shells 
  intact. 
  The 
  planted 
  shells 
  had 
  

   settled 
  quite 
  deep 
  into 
  the 
  mud, 
  and 
  this 
  maj" 
  have 
  been 
  a 
  partial 
  cause 
  

   of 
  death; 
  but 
  from 
  the 
  fact 
  that 
  all 
  died 
  at 
  about 
  the 
  same 
  time, 
  and 
  

   that 
  during 
  July 
  the 
  parasitic 
  worm 
  {Bucej>halus 
  cucuIks) 
  already 
  

   referred 
  to 
  had 
  infested 
  them 
  in 
  great 
  numbers, 
  1 
  am 
  inclined 
  to 
  

   believe 
  that 
  the 
  parasite 
  is 
  accountable 
  for 
  much 
  of 
  the 
  loss. 
  No 
  spat 
  

   attached 
  to 
  the 
  shells 
  after 
  this 
  time; 
  at 
  least, 
  none 
  was 
  found 
  on 
  those 
  

   examined 
  September 
  12, 
  1902.
