  are 
  reddest 
  at 
  the 
  top 
  become 
  porous 
  upon 
  exposure 
  by 
  the 
  

   removal 
  of 
  the 
  small 
  concretions. 
  Ten

  At 
  the 
  south 
  end 
  of 
  the 
  quarry 
  these 
  layers 
  are 
  of 
  a 
  more 
  

   decided 
  green 
  color, 
  and 
  the 
  concretions 
  are 
  virtually 
  restricted 
  

   to 
  a 
  thin 
  portion 
  at 
  the 
  top. 
  These 
  upper 
  red 
  and 
  green 
  layers 
  

   where 
  compact 
  and 
  coming 
  out 
  with 
  clean 
  surface, 
  bear 
  the 
  " 
  fucoi- 
  

   dal" 
  markings 
  characterizing 
  certain 
  beds 
  observed 
  at 
  South 
  

   Oxford, 
  Greene 
  and 
  Smithville 
  to 
  which 
  reference 
  will 
  be 
  made. 
  

   These 
  surface-markings 
  are 
  branching 
  cavity-fillings 
  composed 
  of 
  

   sand 
  -grains. 
  The 
  strata 
  bearing 
  them 
  have 
  the 
  same 
  lithological 
  

   character 
  wherever 
  observed. 
  

  

  No 
  fossils 
  were 
  observed 
  in 
  this 
  section, 
  except 
  Lepidodendra 
  

   Khodeas, 
  branching 
  fern 
  stipes, 
  which 
  are 
  abundant 
  in 
  the 
  lower 
  

   benches 
  of 
  sandstone. 
  

  

  Station 
  G. 
  Quarry 
  on 
  the 
  property 
  of 
  Walker 
  Potter^ 
  on 
  the 
  side 
  

   hill 
  one-quarter 
  mile 
  north 
  of 
  the 
  village 
  of 
  Oxford 
  on 
  the 
  east 
  side 
  

   of 
  the 
  river. 
  Elevation 
  above 
  river 
  approximately 
  300 
  feet. 
  The 
  

   exposure 
  here 
  consists 
  of 
  five 
  feet 
  of 
  compact 
  greenish 
  sandstone 
  

   which 
  breaks 
  out 
  as 
  fine 
  thin 
  flags 
  of 
  excellent 
  qualit}^. 
  ~No 
  

   stripping 
  is 
  necessary, 
  the 
  top 
  layer 
  of 
  sandstone 
  lying 
  under 
  

   about 
  four 
  feet 
  of 
  drift, 
  and 
  beautifully 
  marked 
  with 
  glacial 
  striae 
  

   running 
  nearly 
  north 
  and 
  south, 
  parallel 
  to 
  the 
  valley 
  at 
  this 
  place. 
  

  

  Following 
  up 
  the 
  hill 
  back 
  of 
  the 
  quarry 
  to 
  the 
  bed 
  of 
  the 
  

   New 
  York, 
  Ontario 
  and 
  Western 
  railroad, 
  there 
  is, 
  at 
  an 
  elevation 
  

   of 
  about 
  fifty 
  feet, 
  a 
  small 
  opening 
  into 
  an 
  exceedingly 
  hard 
  

   quartz 
  sandstone, 
  very 
  light 
  gray 
  or 
  whitish 
  in 
  color, 
  with 
  parallel 
  

   horizontal 
  rows 
  of 
  minute 
  rusty 
  grain 
  cavities. 
  For 
  the 
  succeed- 
  

   ing 
  100 
  feet 
  to 
  the 
  railroad 
  these 
  red 
  shales 
  predominate, 
  sandy 
  in 
  

   some 
  places, 
  soft 
  and 
  clayey 
  in 
  others. 
  The 
  upper 
  bank 
  in 
  the 
  

   railroad 
  cut 
  shows 
  that 
  these 
  shales 
  are 
  overlaid 
  by 
  a 
  single 
  bench 
  

   of 
  gray 
  sandstone, 
  two 
  feet 
  six 
  inches 
  thick.

  (1) 
  Light, 
  bluish-gray 
  sandstone, 
  strongly 
  water-laminated, 
  

   and 
  though 
  exposing 
  compact 
  wall-faces, 
  breaking 
  out 
  into 
  thin 
  

   flags, 
  two 
  to 
  four 
  inches 
  in 
  thickness. 
  These 
  are

  red 
  sandstones 
  which,

  am 
  informed,
