  The 
  principal 
  gas 
  horizon 
  of 
  the 
  shallow 
  wells 
  is 
  in 
  the 
  lower 
  

   part 
  of 
  the 
  Marcellus 
  shale, 
  and 
  near 
  the 
  Stafford 
  limestone. 
  

   While 
  in 
  a 
  number 
  of 
  cases 
  gas 
  has 
  been 
  found 
  above 
  the 
  Staf- 
  

   ford 
  horizon, 
  the 
  weight 
  of 
  evidence 
  goes 
  to 
  show 
  that„the 
  gas 
  

   originates 
  in 
  the 
  densely 
  bituminous 
  black 
  shales 
  at 
  the 
  base 
  

   of 
  the 
  Marcellus 
  and 
  is 
  held 
  in 
  by 
  the 
  limestone 
  which 
  serves 
  

   either 
  as 
  a 
  cap 
  where 
  it 
  is 
  continuous, 
  or 
  as 
  a 
  reservoir 
  where 
  it 
  

   contains 
  loose 
  joints 
  and 
  fissures. 
  The 
  pocket 
  of 
  gas 
  at 
  805 
  feet 
  

   in 
  the 
  deep 
  wells 
  appears 
  to 
  be 
  too 
  deep 
  to 
  lie 
  in 
  the 
  honeycombed 
  

   " 
  bullhead 
  " 
  waterlime 
  at 
  the 
  top 
  of 
  the 
  Salina 
  group, 
  and 
  is 
  

   probably 
  a 
  small 
  inconstant 
  horizon. 
  There 
  is 
  nothing 
  in 
  either 
  

   the 
  records 
  or 
  in 
  the 
  drillings 
  preserved 
  to 
  show 
  that 
  the 
  white 
  

   or 
  " 
  quartzose 
  " 
  Medina 
  sandstone 
  exists 
  here. 
  The 
  gas 
  rock 
  in 
  

   the 
  Medina, 
  as 
  shown 
  by 
  the 
  drillings, 
  is 
  a 
  nearly 
  pure, 
  compact 
  

   red 
  sandstone 
  having 
  the 
  usual 
  characteristics 
  of 
  the 
  Medina 
  of 
  

  

  western 
  New 
  York. 
  

  

  Vincent 
  

  

  At 
  Vincent 
  in 
  the 
  town 
  of 
  Bristol 
  a 
  well 
  sunk 
  in 
  1865 
  fur- 
  

   nished 
  a 
  small 
  amount 
  of 
  gas 
  which 
  apparently 
  came 
  from 
  the 
  

   Marcellus. 
  The 
  borings 
  at 
  Canandaigua, 
  Clifton 
  Springs, 
  Naples 
  

   and 
  elsewhere 
  in 
  Ontario 
  co. 
  have 
  produced 
  no 
  gas 
  of 
  any 
  impor- 
  

   tance. 
  

  

  From 
  the 
  Canandaigua 
  lake 
  region 
  C. 
  A. 
  Ashburner 
  reports 
  

   petroleum 
  in 
  several 
  wells, 
  one 
  of 
  which 
  is 
  said 
  to 
  have 
  pro- 
  

   duced 
  five 
  barrels 
  a 
  day. 
  This 
  report 
  I 
  have 
  not 
  been 
  able 
  to 
  

   verify.
