  doubtless 
  severe, 
  the 
  ultimate 
  effect 
  upon 
  the 
  animal's 
  future 
  growth 
  

   and 
  activity 
  was 
  insignificant

  FIELD 
  RECORDS. 
  

  

  A 
  tabular 
  record 
  was 
  kept 
  of 
  all 
  specimens 
  tagged. 
  The 
  weights 
  

   were 
  taken 
  in 
  grams, 
  a 
  Harvard 
  trip 
  balance 
  being 
  used 
  ; 
  the 
  measure- 
  

   ments, 
  length, 
  height, 
  and 
  breadth 
  in 
  millimeters 
  with 
  a 
  steel 
  

   caliper. 
  The 
  field 
  record 
  form, 
  kept 
  in 
  duphcate, 
  was 
  ruled 
  in 
  

   columns 
  with 
  headings 
  for 
  number, 
  weight, 
  length, 
  height, 
  breadth, 
  

   species, 
  and 
  remarks. 
  

  

  PLANTING 
  SITES. 
  

  

  In 
  most 
  cases, 
  after 
  tagging 
  and 
  taking 
  records, 
  the 
  mussels 
  were 
  

   placed 
  directly 
  back 
  in 
  their 
  original 
  habitats, 
  but 
  in 
  some 
  instances 
  

   transplantmg 
  from 
  river 
  to 
  creek 
  or 
  from 
  pond 
  to 
  river 
  was 
  practiced. 
  

  

  Four 
  different 
  sites 
  were 
  selected 
  for 
  planting: 
  One 
  on 
  Shoofly 
  

   Creek, 
  on 
  the 
  Corn 
  farm 
  in 
  the 
  north 
  end 
  of 
  Kay 
  County, 
  Okla.; 
  

   two 
  on 
  the 
  Chikaskia 
  River, 
  on 
  the 
  Brewer 
  and 
  Esch 
  farms 
  near 
  

   Tonkawa, 
  Okla.; 
  and 
  a 
  pond 
  site 
  on 
  the 
  Browne 
  farm 
  near 
  Autwine. 
  

   As 
  the 
  pond 
  dried 
  up, 
  due 
  to 
  the 
  unusual 
  drought 
  of 
  1910, 
  this 
  series 
  

   does 
  not 
  figure 
  in 
  the 
  results. 
  

  

  The 
  Chikaskia 
  River 
  is 
  a 
  small, 
  clear-water, 
  sandy 
  stream. 
  The 
  

   sand 
  is 
  coarse, 
  and 
  frequently 
  there 
  are 
  stretches 
  of 
  gravel 
  and 
  

   occasionally 
  mud 
  banks 
  and 
  small, 
  mud-bottomed 
  side 
  channels. 
  

   In 
  certain 
  portions 
  of 
  the 
  Chikaskia, 
  Unionidse 
  are 
  abundant. 
  

  

  Shoofly 
  Creek 
  is 
  a, 
  tributary 
  of 
  the 
  Chikaskia. 
  In 
  very 
  dry 
  weather 
  

   the 
  water 
  stops 
  flowing 
  over 
  the 
  shallow, 
  gravelly 
  stretches; 
  but 
  

   the 
  ponded 
  sections, 
  often 
  a 
  mile 
  in 
  length 
  and 
  with 
  water 
  2 
  to 
  6 
  

   feet 
  deep, 
  havo 
  a 
  constant 
  water 
  supply. 
  In 
  certain 
  of 
  these 
  ponded 
  

   portions 
  mussels 
  are 
  fairly 
  abundant 
  . 
  

  

  PLANTING 
  OF 
  TAGGED 
  SPECIMENS. 
  

  

  In 
  all, 
  about 
  900 
  specimens 
  were 
  tagged, 
  weighed, 
  measured, 
  and 
  

   listed 
  for 
  future 
  observation. 
  For 
  convenience 
  in 
  further 
  dis- 
  

   cussion 
  these 
  specimens 
  may 
  be 
  grouped 
  into 
  seven 
  lots. 
  

  

  SHOOFLY 
  CREEK. 
  

  

  Shoofly, 
  lot 
  A, 
  140 
  specimens, 
  and 
  lot 
  B, 
  80 
  specimens. 
  — 
  Nearly 
  

   aU 
  of 
  these 
  were 
  Quadrula 
  undulata 
  (three-ridge) 
  and 
  were 
  taken 
  

   from 
  the 
  direct 
  site 
  where 
  they 
  were 
  planted 
  after 
  tagging. 
  All 
  

   of 
  the 
  Q. 
  undulata 
  (three-ridge) 
  secured 
  in 
  the 
  Shoofly 
  were 
  large; 
  

   out 
  of 
  some 
  500 
  specimens 
  handled 
  in 
  two 
  days, 
  only 
  4 
  weighed 
  

   under 
  200 
  grams.
