  The

  of 
  the 
  Onondaga

  groujp^ 
  which 
  form 
  the 
  next 
  

   rise 
  by 
  the 
  side 
  of 
  the 
  creek. 
  

  

  The 
  red 
  shales 
  of 
  tlie 
  latter 
  group 
  are 
  recorded 
  by 
  Brig- 
  

   ham 
  ('

  in 
  the 
  ravines 
  on 
  the 
  north 
  and

  of 
  Paris 
  hill 
  

   in 
  New

   at

  Hartford, 
  about 
  three 
  and 
  a 
  half 
  miles 
  north 
  of 
  Chadwick 
  

   Mills, 
  useful 
  for 
  comparison 
  with 
  the 
  latter, 
  when 
  correlated, 
  is 
  as 
  

   follows 
  : 
  

  

  The 
  section 
  begins 
  below 
  the 
  quartzose 
  sandstone, 
  (number 
  6 
  of 
  

   our 
  Chadwick 
  Mills 
  section), 
  " 
  and 
  consequently 
  is 
  between 
  60 
  and 
  

   10 
  feet 
  below 
  the 
  top 
  of 
  the 
  group, 
  as 
  nearly 
  as 
  can 
  be 
  ascertained." 
  

  

  1) 
  Oneida 
  conglomerate. 
  

  

  2) 
  (Blackstone 
  and 
  Davis' 
  quarries 
  at 
  head 
  of 
  Sylvan 
  glen.) 
  

  

  Alternating 
  layers 
  of 
  shaly 
  sandstone 
  and 
  conglomerate 
  

   with 
  shale. 
  6 
  or 
  7 
  feet 
  of 
  dark 
  gray 
  or 
  red 
  sandstone 
  occur 
  

   at 
  the 
  base 
  of 
  the 
  quarries, 
  none 
  of 
  the 
  layers, 
  except 
  the 
  

   upper, 
  being 
  over 
  6 
  or 
  7 
  inches 
  thick 
  and 
  some 
  but 
  half 
  

   an 
  inch 
  thick, 
  and 
  separated 
  by 
  or 
  coated 
  with 
  shale, 
  which 
  

   is 
  blue 
  when 
  fresh, 
  becoming 
  yellowish. 
  (Same 
  as 
  E 
  2 
  in 
  

   the 
  Swift 
  creek 
  section.) 
  Lower 
  surfaces 
  covered 
  with 
  

   Rusojphycus 
  hilobatus^ 
  most 
  numerous 
  on 
  the 
  thin 
  layers, 
  

   also 
  other 
  fucoids, 
  Platystoma^ 
  Avicula 
  rhomboidea^ 
  

   BuGcania 
  trilobata^ 
  Beyrichia^ 
  Pyrenomoeus 
  cuneatus. 
  

   The 
  whole 
  of 
  these 
  fossils 
  is 
  replaced 
  with 
  hydrate 
  of 
  

   iron. 
  The 
  sandstone 
  is 
  covered 
  with 
  shale 
  of 
  a 
  yellowish 
  

   green 
  color 
  8 
  to 
  10 
  feet 
  thick 
  in 
  very 
  thin, 
  leaf-like 
  

   divisions, 
  which 
  is 
  apparently 
  non-fossiliferous. 
  

  

  The 
  upper 
  layers 
  consist 
  of 
  small 
  pebbles 
  of 
  white 
  or 
  

   pink 
  quartz, 
  with 
  some 
  elongated 
  black 
  ones.

  In 
  the 
  shale 
  which 
  covers 
  the 
  ore 
  

   lighter 
  colored 
  arborescent 
  markings 
  are 
  seen, 
  which 
  may 
  

   be 
  due 
  to 
  moisture, 
  organic 
  origin 
  or 
  deconiposition.
