  north 
  of 
  the 
  Charlotte 
  river, 
  northeast 
  of 
  Davenport 
  

   Center, 
  at 
  an 
  elevation 
  of 
  some 
  166 
  feet 
  above 
  the 
  river 
  level 
  are 
  

   ledges 
  of 
  bluish 
  shales 
  (LXXII

  ) 
  containing 
  Ithaca

  About 
  

   60 
  feet 
  higher 
  are 
  large, 
  loose 
  blocks 
  of 
  the 
  Oneonta 
  sandstone 
  

   which 
  caps 
  the 
  hill 
  and 
  have 
  probably 
  rolled 
  down 
  from 
  it. 
  On 
  

   the 
  north 
  side 
  of 
  the 
  river, 
  about 
  three 
  fourths 
  of 
  a 
  mile 
  north- 
  

   east 
  of 
  Davenport, 
  almost 
  opposite 
  the 
  mouth 
  of 
  Middle 
  brook, 
  

   and 
  nearly 
  70 
  feet 
  above 
  the 
  river 
  road 
  are 
  ledges 
  of 
  bluish 
  

   shales 
  (LXXII

  in 
  the 
  Ithaca 
  formation 
  from 
  which 
  the 
  follow- 
  

   ing 
  four 
  species 
  were 
  obtained 
  as 
  the 
  result 
  of 
  a

  One 
  fourth 
  of 
  a 
  mile 
  northeast 
  of 
  Fergusonville, 
  by 
  the 
  side 
  of 
  

   the 
  highway, 
  there 
  is 
  an 
  exposure 
  of 
  15 
  feet 
  of 
  bluish 
  shales 
  and 
  

   sandstone 
  (LXXIIB

  ). 
  The 
  rocks 
  belong 
  in 
  the 
  Ithaca 
  formation; 
  

   but 
  are 
  not 
  very 
  fossiliferous. 
  Specimens 
  of 
  LiorJiynchas 
  mesacos- 
  

   talis 
  Hall 
  and 
  Microdon 
  (Cypricardella) 
  gregarius 
  Hall 
  were 
  

   obtained. 
  

  

  Along 
  a 
  small 
  brook, 
  a 
  northern 
  branch 
  of 
  Middle 
  brook, 
  in 
  the 
  

   northeastern 
  corner 
  of 
  Kortright 
  township 
  about 
  three 
  miles 
  

   southeast 
  of 
  Davenport, 
  are 
  bluish 
  shaly 
  sandstones 
  (XXXII 
  A

   containing 
  fossils. 
  Those 
  found 
  were:

   The

  is 
  perhaps 
  one 
  half 
  mile 
  above 
  the 
  valley 
  road 
  

  

  along 
  Middle 
  brook

   of
