   Approximately 
  340 
  feet 
  above 
  the 
  stone 
  quarry 
  and 
  south 
  of 
  

  

  the 
  highway 
  up 
  the 
  hill 
  in 
  northwestern 
  Broome, 
  just 
  over 
  the 
  

   township 
  line, 
  is 
  a 
  small 
  excavation 
  showing 
  blue 
  sandstone 
  (D 
  4 
  ) 
  

   which 
  splits 
  into 
  rather 
  thin 
  layers. 
  No 
  fossils 
  were 
  found 
  in 
  

   the 
  bed 
  rock; 
  although 
  there 
  are 
  plenty 
  in 
  loose 
  pieces 
  of 
  stone 
  

   on 
  the 
  surface 
  which, 
  however, 
  probably 
  came 
  with 
  the 
  drift. 
  

   On 
  the 
  highway 
  just 
  after 
  it 
  turns 
  south 
  in 
  the 
  northwestern 
  

   corner 
  of 
  Broome 
  and 
  145 
  feet 
  above 
  D 
  4 
  are 
  green 
  shales 
  and 
  thin 
  

   sandstones 
  (D 
  6 
  ) 
  which 
  are 
  in 
  the 
  Sherburne 
  formation. 
  On 
  the 
  

   highway 
  30 
  feet 
  higher 
  near 
  the 
  turn 
  to 
  Franklinton 
  are 
  red 
  and 
  

   green 
  mottled 
  shales 
  and 
  sandstones 
  (D 
  8 
  ). 
  Another 
  prominent 
  

   terrace 
  of 
  grayish, 
  slightly 
  reddish 
  and 
  greenish 
  shaly 
  : 
  sandstone 
  

   (D 
  10 
  ) 
  appears 
  65 
  feet 
  higher. 
  Below 
  this 
  terrace 
  along 
  the 
  high- 
  

   way 
  are 
  shales 
  which 
  are 
  mainly 
  red. 
  At 
  the 
  top 
  of 
  the 
  ridge 
  is 
  

   grayish 
  and 
  greenish 
  gray, 
  coarse 
  grained, 
  thin 
  bedded 
  sandstone 
  

   (D 
  12 
  ). 
  In 
  the 
  field 
  plenty 
  of 
  loose 
  red 
  sandstone 
  is 
  found. 
  The 
  

   summit 
  of 
  the 
  hill 
  in 
  the 
  eastern 
  part 
  of 
  Fulton 
  township 
  is 
  only 
  

   about 
  35 
  feet 
  higher 
  and 
  this 
  summit 
  according 
  to 
  the 
  barometric 
  

   section 
  is 
  1500 
  feet 
  above 
  the 
  Schoharie 
  river 
  at 
  Middleburg. 
  On 
  

   the 
  side 
  of 
  the 
  hill 
  are 
  loose 
  specimens 
  of 
  rock 
  containing 
  Hamil- 
  

   ton 
  species, 
  the 
  following 
  having 
  been 
  collected: 
  

  

  1 
  Spirifer 
  mucronatus 
  (Con.) 
  Bill. 
  (c) 
  

  

  2 
  Tropidoleptus 
  carinatus

  Imperfect 
  specimens.

  Internal 
  impressions 
  poorly 
  preserved. 
  

  

  The 
  rocks 
  from 
  D 
  8 
  to 
  the 
  top 
  of 
  Moheganter 
  hill 
  have 
  in 
  general 
  

   the 
  lithologic 
  characters 
  of 
  the, 
  Oneonta 
  formation 
  to 
  which 
  they 
  

   would 
  ordinarily 
  be 
  referred. 
  The 
  reds 
  and 
  greenish 
  gray 
  rocks 
  

   on 
  this 
  hill, 
  however, 
  appear 
  stratigraphically 
  much 
  lower 
  than 
  

   the 
  base 
  of 
  the 
  Oneonta 
  sandstone 
  in 
  the 
  Susquehanna 
  valley 
  

   or 
  even 
  in 
  the 
  western 
  part 
  of 
  Schoharie 
  co., 
  so 
  that 
  they 
  

   have 
  nearly, 
  if 
  not 
  completely, 
  replaced 
  the 
  rocks 
  of 
  the 
  Ithaca
