  Granite 
  Bowlders 
  in 
  (f) 
  

  

  On 
  the 
  forty 
  acres 
  east 
  of 
  the 
  road 
  (5 
  on 
  the 
  map) 
  small 
  

   granite 
  bowlders 
  are 
  not 
  uncommon 
  and 
  a 
  few 
  large 
  chunks 
  

   were 
  seen 
  in 
  the 
  hollows 
  and 
  hedges 
  where 
  it 
  is 
  clear 
  they 
  had 
  

   been 
  thrown. 
  Xo 
  one 
  of 
  these 
  exceeded 
  a 
  weight 
  estimated 
  at 
  

   twenty-live 
  pounds. 
  The 
  forty 
  acres 
  to 
  the 
  north 
  (6 
  on 
  the 
  

   map) 
  has 
  the 
  Stanton 
  limestone 
  over 
  most 
  of 
  its 
  area 
  as 
  the 
  

   surface 
  rock 
  and, 
  save 
  for 
  the 
  southwest 
  corner, 
  no 
  bowlders 
  

   are 
  present, 
  while 
  the 
  tract 
  of 
  forty 
  acres 
  to 
  the 
  south 
  has 
  a 
  

   very 
  few 
  small 
  ones 
  and 
  these 
  were 
  probably 
  carried 
  through 
  

   human 
  agencies 
  to 
  the 
  places 
  where 
  they 
  occur. 
  On 
  the 
  forty 
  

   acres 
  to 
  the 
  east 
  of 
  5 
  (8 
  on 
  the 
  map) 
  a 
  few 
  small 
  bowlders 
  are

  erne 
  group 
  of 
  bowlders 
  on 
  the 
  most 
  western 
  mound. 
  

   Bowlders 
  are 
  quite 
  thick 
  in 
  the 
  bushes 
  on 
  the 
  right 
  background. 
  The 
  handle 
  

   of 
  the 
  hammer 
  is 
  sixteen 
  inches 
  long. 
  

  

  present 
  which 
  have 
  been 
  brought 
  there 
  in 
  cultivation, 
  or 
  they 
  

   may 
  be 
  the 
  last 
  surviving 
  fragments 
  of 
  large 
  bowlders 
  which 
  

   may 
  once 
  have 
  been 
  over 
  the 
  field. 
  It 
  is 
  deeply 
  eroded 
  so 
  far 
  as 
  

   the 
  shales 
  are 
  concerned 
  and 
  the 
  surface 
  is 
  nearly 
  on 
  the 
  

   Stanton 
  limestone, 
  which 
  is 
  also 
  true 
  of 
  T. 
  

  

  These 
  are 
  all 
  the 
  places 
  where 
  granite 
  bowlders 
  were 
  

   observed. 
  The 
  surrounding 
  country 
  for 
  from 
  ten 
  to 
  fifty 
  miles 
  

   in 
  every 
  direction 
  was 
  quite 
  thoroughly 
  examined 
  and 
  at 
  no 
  

   place 
  was 
  a 
  single 
  granite 
  bowlder 
  found, 
  and, 
  so 
  far 
  as 
  the 
  

   writer 
  is 
  aware, 
  none 
  has 
  ever 
  been 
  reported, 
  and 
  the 
  nearest 
  

   locality 
  where 
  such 
  are 
  known 
  to 
  occur 
  is 
  about 
  seventy-five 
  

   miles 
  to 
  the 
  north 
  in 
  the 
  drift 
  of 
  the 
  Kansas 
  ice 
  sheet.
