﻿CLASSIFICATION,

  frequent 
  exposures 
  of 
  the 
  Hamilton 
  and 
  higher 
  rocks 
  in 
  its 
  upper 
  

   part 
  makes 
  an 
  excellent 
  section. 
  In 
  the 
  Foxkill 
  at 
  West 
  Berne 
  

   are 
  excellent 
  outcrops 
  of 
  the 
  Onondaga 
  limestone 
  which 
  contain 
  

   numerous 
  corals 
  as 
  described 
  by 
  Darton.« 
  The 
  top 
  of 
  the 
  Onon- 
  

   daga 
  limestone 
  is 
  apparently 
  shown 
  in 
  -a 
  small 
  brook 
  not 
  far 
  

   southwest 
  of 
  the 
  village, 
  but 
  the 
  drift 
  has 
  covered 
  about 
  all 
  of 
  

   the 
  Marcellus 
  shale 
  on 
  the 
  hill 
  to 
  the 
  south. 
  

  

  Along 
  the 
  Bradt 
  hollow 
  road 
  for 
  380 
  feet 
  above 
  the 
  Onondaga 
  

   limestone, 
  according 
  to 
  the 
  barometer, 
  the 
  rocks 
  are 
  concealed 
  

   when 
  coarse 
  argillaceous 
  to 
  arenaceous 
  shales 
  (B 
  2 
  ) 
  containing 
  

   plenty 
  of 
  Hamilton 
  fossils 
  outcrop. 
  These 
  fossils 
  show 
  that 
  the 
  

   rocks 
  are 
  stratigraphically 
  above 
  the 
  Marcellus 
  shales 
  and 
  the 
  

   difference 
  in 
  altitude 
  is 
  not 
  as 
  great 
  as 
  the 
  thickness 
  of 
  the 
  rocks 
  

   since 
  the 
  direction 
  of 
  the 
  section 
  agrees 
  quite 
  closely 
  with 
  that 
  

   of 
  the 
  dip 
  which 
  is 
  pretty 
  heavy 
  in 
  this 
  region. 
  A 
  stratum 
  of 
  

   quite 
  heavy 
  sandstone 
  (B 
  3 
  ) 
  which 
  splits 
  into 
  thin 
  layers 
  forms 
  a 
  

   conspicuous 
  ledge 
  140 
  feet 
  above 
  the 
  shales.

  the

  of 
  the 
  highway

  the 
  upper 
  part 
  of 
  

   Bradt 
  hill 
  3.4 
  miles 
  SSW 
  of 
  West 
  Berne 
  and 
  835 
  feet 
  higher 
  than 
  

   the 
  Onondaga 
  limestone 
  is 
  a 
  fair 
  exposure 
  of 
  fine, 
  bluish 
  argil- 
  

   laceous 
  shales 
  containing 
  plenty 
  of 
  Hamilton 
  fossils. 
  At 
  the 
  

   base 
  of 
  the 
  outcrop 
  is 
  a 
  bluish 
  sandstone 
  two 
  feet 
  thick, 
  succeed- 
  

   ing 
  which 
  are 
  rather 
  more 
  than 
  five 
  feet

  the 
  fossiliferous
