  The 
  wells 
  on 
  the 
  west 
  side 
  of 
  the 
  valley 
  at 
  Warsaw 
  are 
  the 
  

   most 
  westerly 
  ones 
  in 
  which 
  rock 
  salt 
  has 
  been 
  found, 
  so 
  far 
  as 
  is 
  

   certainly 
  known, 
  but 
  the 
  thickness 
  of 
  the 
  beds 
  of 
  salt 
  found 
  there 
  

   would 
  lead 
  to 
  the 
  presumption 
  that 
  they 
  extend 
  considerably 
  

   further 
  in 
  that 
  direction. 
  

  

  The 
  elevation 
  of 
  the 
  strata 
  on 
  the 
  north 
  brings 
  the 
  horizon 
  of 
  

   the 
  salt 
  beds 
  to 
  the 
  surface 
  (when 
  not 
  covered 
  by 
  the 
  drift) 
  in 
  

   a 
  narrow 
  belt 
  extending 
  in 
  an 
  easterly 
  direction 
  across 
  the 
  north 
  

   part 
  of 
  Genesee 
  county 
  and 
  the 
  southern 
  part 
  of 
  both 
  Monroe 
  

   and 
  "Wayne 
  counties, 
  where 
  springs 
  of 
  brackish 
  water 
  are 
  of 
  

   frequent 
  occurrence, 
  and 
  brine 
  of 
  considerable 
  strength 
  has 
  been 
  

   found 
  in 
  many 
  wells 
  drilled 
  into 
  rock, 
  but 
  there 
  is 
  no 
  record 
  that 
  

   rock 
  salt 
  has 
  been 
  found 
  north 
  of 
  the 
  line 
  of 
  outcrop 
  of 
  the 
  top 
  

   of 
  the 
  Corniferous 
  limestone 
  which 
  is 
  exposed 
  at 
  Batavia, 
  Staf- 
  

   ford, 
  Le 
  Roy, 
  Caledonia, 
  Avon, 
  Mendon, 
  Victor, 
  Farmington, 
  

   Manchester 
  and 
  Phelps, 
  and 
  may 
  be 
  considered 
  to 
  be 
  the 
  

   northern 
  boundary 
  of 
  the 
  salt 
  district. 
  

  

  The 
  southern 
  boundary 
  of 
  the 
  salt 
  field 
  is 
  not 
  well 
  established. 
  

   In 
  the 
  deep 
  wells 
  at 
  Gainesville 
  creek, 
  Castile, 
  Nunda, 
  Dansville, 
  

   Naples, 
  Dundee 
  and 
  Watkins 
  thick 
  beds 
  of 
  clear 
  salt 
  were 
  

   reached, 
  and 
  it 
  is 
  probable 
  that 
  they 
  extend 
  much 
  further 
  toward 
  

   the 
  south, 
  though 
  the 
  elevation 
  of 
  the 
  surface 
  and 
  the 
  dip 
  of 
  the 
  

   strata 
  put 
  them 
  beyond 
  reach 
  for 
  commercial 
  purposes. 
  

  

  The 
  Oatka 
  valley, 
  or 
  Warsaw 
  salt 
  district, 
  embraces 
  the 
  terri- 
  

   tory 
  drained 
  by 
  the 
  Oatka 
  river 
  between 
  Le 
  Roy 
  and 
  the 
  head- 
  

   waters 
  of 
  that 
  stream, 
  and 
  is 
  wholly 
  within 
  the 
  limits 
  of 
  Genesee 
  

   and 
  Wyoming 
  counties. 
  

  

  The 
  geological 
  position 
  of 
  the 
  mouths 
  of 
  the 
  salt 
  wells 
  in 
  the 
  

   district 
  is 
  as 
  follows 
  : 
  The 
  first 
  rock 
  reached 
  in 
  the 
  wells 
  of 
  the 
  

   Le 
  Roy 
  Salt 
  Company, 
  near 
  the 
  village, 
  belongs 
  to 
  the 
  Marcellus 
  

   group 
  or 
  to 
  the 
  lower 
  shales 
  of 
  the 
  Hamilton 
  group. 
  

  

  The 
  horizon 
  of 
  the 
  mouth 
  of 
  the 
  Lehigh 
  shaft 
  is 
  in 
  the 
  soft 
  

   gray 
  Ludlow 
  ville 
  shale, 
  122 
  feet 
  above 
  the 
  bottom 
  of 
  the 
  Hamil- 
  

   ton 
  group. 
  

  

  In 
  the 
  well 
  known 
  as 
  the 
  Junction 
  well, 
  forty 
  -six 
  feet 
  of 
  drift 
  

  

  and 
  132 
  feet 
  of 
  the 
  lower 
  Hamilton 
  shales 
  were 
  passed 
  through. 
  

  

  The 
  horizon 
  of 
  the 
  mouth 
  of 
  the 
  well 
  at 
  Pavilion 
  is 
  very 
  

  

  closely 
  that 
  of 
  the 
  top 
  of 
  the 
  Hamilton, 
  as 
  exposed 
  half 
  a 
  mile 
  

  

  north. 
  The 
  top 
  of 
  the 
  Corniferous 
  limestone 
  was 
  reached 
  in 
  this
