  100 
  feet 
  higher 
  on 
  the

   from 
  higher 
  ledges, 
  containing 
  an 
  Ithaca

  About 
  50 
  feet 
  higher 
  is 
  the 
  Aaron 
  Silvernaile 
  quarry 
  (D

  ) 
  

   where 
  some 
  eight 
  or 
  nine 
  feet 
  of 
  blue, 
  flagging 
  stone 
  is 
  shown. 
  

   The 
  sandstone 
  splits 
  into 
  layers 
  from 
  one 
  and 
  one 
  half 
  to 
  four 
  

   inches 
  in 
  thickness 
  and 
  the 
  quarry 
  has 
  been 
  worked 
  to 
  a 
  consider- 
  

   able 
  extent 
  for 
  flagging 
  stone. 
  Above 
  the 
  sandstone 
  are 
  shaly 
  

   layers 
  in 
  which 
  fossils 
  are 
  fairly 
  common. 
  The
