   These 
  rocks 
  are 
  regarded 
  as 
  belonging 
  in 
  the 
  Ithaca 
  formation 
  

  

  which 
  consequently 
  caps 
  the 
  hill 
  and 
  loose 
  on 
  the 
  surface 
  of 
  its 
  

   top 
  are 
  numerous 
  angular 
  fragments 
  of 
  rock, 
  containing 
  the 
  

   Ithaca 
  fauna, 
  which 
  evidently 
  came 
  from 
  that 
  region. 
  On 
  the 
  

   highway 
  crossing 
  the 
  hill, 
  just 
  over 
  the 
  divide 
  on 
  the 
  eastern 
  

   slope, 
  is 
  a 
  ledge 
  of 
  sandstone 
  and 
  bluish 
  shales 
  (X 
  7 
  ) 
  containing 
  

   Ithaca 
  fossils. 
  This 
  outcrop 
  is 
  about 
  50 
  feet 
  higher 
  than 
  the 
  

   arenaceous 
  shales 
  of

  in 
  the 
  field 
  some 
  distance 
  to

  of 
  

   the
