  mature, 
  and 
  the 
  addition 
  of 
  the 
  260,000,000 
  removed 
  would 
  

   raise 
  this 
  percentage 
  to 
  68, 
  which 
  would 
  make 
  the 
  ratio 
  even 
  

   smaller. 
  

  

  Hence, 
  the 
  addition 
  of 
  a 
  large 
  number 
  of 
  mature 
  oysters 
  

   to 
  the 
  total 
  number 
  considered 
  in 
  both 
  Sounds 
  Avould 
  prove 
  

   even 
  more 
  conclusively 
  that 
  the 
  fecundity 
  was 
  greatly 
  im- 
  

   paired. 
  

  

  The 
  two 
  beds 
  of 
  Mdiich 
  we 
  have 
  the 
  most 
  exact 
  and 
  com- 
  

   plete 
  statistical 
  records 
  in 
  this 
  season 
  are 
  the 
  Woman's 
  Marsh 
  

   and 
  the 
  Great 
  Eock, 
  and, 
  by 
  means 
  of 
  the 
  record 
  of 
  statis- 
  

   tics, 
  I 
  estimate 
  that 
  the 
  following 
  number 
  of 
  oysters 
  have 
  

   been 
  removed 
  from 
  them 
  : 
  

  

  TABLE 
  showing 
  number 
  Oysters 
  Eevioved 
  from 
  Oreat 
  Reck 
  and 
  Woman's 
  

  

  Marsh. 
  

  

  From 
  Table 
  II, 
  Dredging 
  Results 
  in 
  the 
  Sounds, 
  I 
  find 
  the 
  

   percentage 
  of 
  mature 
  oysters 
  to 
  the 
  total 
  number 
  on 
  the 
  two 
  

   beds 
  mentioned 
  is 
  on 
  the 
  Great 
  Eock 
  24 
  and 
  on 
  the 
  Woman's 
  

   Marsh 
  36. 
  Hence 
  we 
  would 
  have 
  on 
  the 
  Great 
  Rock 
  4± 
  per 
  

   cent, 
  of 
  the 
  oysters 
  mature 
  and 
  full 
  grown, 
  and 
  on 
  the 
  Wo- 
  

   man's 
  Marsh 
  52 
  per 
  cent, 
  mature. 
  

  

  We 
  find 
  by 
  making 
  a 
  similar 
  calculation 
  for 
  Piney 
  Island 
  

   Bar 
  that 
  the 
  percentage 
  of 
  mature 
  oysters 
  removed 
  is 
  70, 
  

   and 
  that 
  by 
  the 
  dredging 
  results 
  20 
  per 
  cent, 
  were 
  mature; 
  

   hence, 
  45 
  per 
  cent, 
  represents 
  the 
  percentage 
  on 
  Piney 
  Island 
  

   Ear. 
  

  

  The 
  ratios 
  on 
  these 
  Ijeds 
  would 
  then, 
  w^ere 
  the 
  oysters 
  re- 
  

   moved 
  still 
  present, 
  be 
  L2on 
  the 
  Great 
  Rock, 
  0.9 
  on 
  the 
  AVo- 
  

   man's 
  Marsh, 
  and 
  1.2 
  on 
  Piney 
  Island 
  Bar. 
  

  

  It 
  will 
  be 
  seen 
  by 
  the 
  above 
  that 
  there 
  has 
  been 
  an 
  exhaus-
