  A 
  few 
  rods 
  to 
  the 
  east 
  of 
  the 
  Cummingis 
  quarry 
  is 
  the 
  

   Blue 
  stone 
  company 
  quarry 
  which 
  in 
  the 
  lower 
  part 
  has 
  five 
  feet, 
  

   fight 
  inches 
  of 
  flagging 
  stone 
  called 
  " 
  blue 
  stone 
  " 
  by 
  the 
  quarry- 
  

   men. 
  The 
  flags 
  split 
  into 
  layers 
  varying 
  from 
  two 
  and 
  a 
  half 
  to 
  

   three 
  inches 
  in 
  thickness, 
  while 
  the 
  layers 
  from 
  four 
  to 
  five 
  inches 
  

   in 
  thickness 
  are 
  used 
  for 
  .curbing. 
  At 
  the 
  top 
  of 
  this 
  flagging 
  

   stone 
  is 
  a 
  layer 
  which 
  thins 
  rapidly 
  toward 
  the 
  northern 
  end 
  of 
  

   the 
  quarry. 
  In 
  the 
  isoufthern 
  part 
  it 
  is 
  one 
  foot, 
  seven 
  inches 
  in 
  

   thickness, 
  while 
  1*00 
  feet 
  farther 
  north 
  it 
  has 
  decreased 
  to 
  three 
  

   inches. 
  Above 
  this 
  are 
  7 
  feet 
  of 
  thin 
  bedded 
  sandstone, 
  thrown 
  

   away 
  in 
  quarrying, 
  that 
  contains 
  Spirifer 
  mucronatus 
  (Con.) 
  Bill, 
  

   and 
  plant 
  stems. 
  Fossils 
  however 
  do 
  not 
  occur 
  abundantly. 
  

   The 
  section 
  is 
  as 
  follows

  Thin 
  bedded 
  sandstone 
  

   Stripping 
  of 
  the 
  quarry 
  

  

  Layer 
  of 
  varying 
  thickness 
  

  

  Bluish

   Quarry 
  stone 
  

  

  Bottom 
  of 
  quarry 
  

  

  There 
  is 
  little 
  soil 
  on 
  the 
  rock 
  so 
  that 
  the 
  stripping 
  is 
  confined 
  

   to 
  the 
  seven 
  feet 
  of 
  thin 
  sandstone 
  layers. 
  The 
  following 
  deter- 
  

   minations 
  of 
  dip 
  were 
  made: 
  

  

  About 
  3° 
  S10°W 
  

   2° 
  to 
  2$°W 
  

  

  4° 
  SW 
  

  

  It 
  varies 
  however 
  in 
  different 
  parts 
  of 
  the 
  quarry 
  since 
  the 
  

   lower 
  layers 
  in 
  the 
  northern 
  part 
  are 
  nearly 
  level. 
  One 
  line 
  of 
  

   joint 
  runs 
  S10°W 
  and 
  N10°E, 
  and 
  this 
  is 
  crossed 
  by 
  another 
  set 
  

   trending 
  east 
  and 
  west. 
  

  

  From 
  the 
  above 
  description 
  it 
  will 
  be 
  seen 
  that 
  the 
  greater 
  part 
  

   of 
  Berne 
  is 
  covered 
  by 
  the 
  Hamilton 
  and 
  Marcellus 
  formations,
