  Imperfectly

  Only 
  a 
  few 
  feet 
  higher 
  are 
  ledges 
  of 
  thin 
  red 
  sandstone 
  and 
  

   mottled 
  red 
  and 
  green 
  shale 
  (Z 
  4 
  ) 
  approximately 
  590 
  feet 
  above 
  

   the 
  level 
  of 
  the 
  Schoharie 
  river. 
  To 
  the 
  north 
  of 
  this 
  hill 
  about 
  

   one 
  mile 
  from 
  West 
  Gilboa 
  is 
  Pigeon 
  creek, 
  a 
  tributary 
  of 
  the 
  

   Minekill 
  from 
  the 
  north. 
  Along 
  the 
  highway 
  on 
  the 
  northern 
  

   bank 
  of 
  this 
  creek 
  as 
  far 
  as 
  the 
  first 
  road 
  are 
  frequent 
  pieces 
  of 
  

   sandstone 
  containing 
  fossils, 
  frequently 
  Spirifer 
  mesastriaUs 
  Hall. 
  

   These 
  blocks 
  were 
  not 
  found 
  in 
  place 
  but 
  it 
  seems 
  probable 
  that 
  

   they 
  occur 
  in 
  place 
  above 
  the 
  zone 
  of 
  reds 
  described 
  near 
  West 
  

   Gilboa. 
  Higher 
  on 
  this 
  hill 
  forming 
  the 
  divide 
  between 
  the 
  

   Minekill 
  and 
  Mill 
  creek 
  are 
  large 
  numbers 
  of 
  loose, 
  angular, 
  

   blocks 
  of 
  red 
  sandstone. 
  This 
  seems 
  to 
  show 
  that 
  a 
  considerable 
  

   amount 
  of 
  the 
  red 
  occurs 
  in 
  this 
  hill 
  interstratified 
  with 
  the 
  

   coarse 
  grained, 
  grayish 
  to 
  greenish 
  gray 
  sandstone. 
  Mixed, 
  loose 
  

   specimens 
  of 
  these 
  two 
  colored 
  sandstones 
  occur 
  well 
  toward 
  

   Ruth 
  church 
  which 
  is 
  on 
  the 
  high 
  part 
  of 
  the 
  divide 
  in 
  the 
  souths 
  

   western 
  part 
  of 
  Blenheim, 
  475 
  feet 
  by 
  the 
  barometer 
  above 
  the 
  

   red 
  sandstone 
  north 
  of 
  West 
  Gilboa. 
  Not 
  far 
  from 
  Ruth 
  are 
  

   large 
  quantities 
  of 
  loose, 
  angular 
  blocks 
  of 
  greenish 
  gray 
  sandstone 
  

   similar 
  to 
  the 
  typical 
  Oneonta. 
  Loose 
  by 
  the 
  highway 
  about 
  one 
  

   fourth 
  mile 
  west 
  of 
  West 
  Gilboa 
  are 
  blocks 
  of 
  greenish 
  sandstone 
  

   containing 
  Ithaca 
  fossils 
  some 
  of 
  them 
  having 
  large 
  numbers 
  of 
  

   Spirifers. 
  It 
  is 
  not 
  clear 
  whether 
  these 
  blocks 
  came 
  from 
  a 
  hori- 
  

   zon 
  below 
  or 
  above 
  the 
  red 
  sandstone 
  of 
  Z 
  4 
  , 
  but 
  the 
  following 
  

   species 
  were 
  collected 
  from 
  them 
  :
