  Summit 
  which 
  is 
  one 
  of 
  the 
  western 
  tier 
  of 
  townships 
  in 
  Scho- 
  

   harie 
  co. 
  lies 
  directly 
  east 
  of 
  Worcester. 
  The 
  central 
  part 
  

   of 
  it 
  is 
  an 
  elevated 
  plateau 
  while 
  in 
  the 
  western 
  part 
  are 
  the 
  

   upper 
  valley 
  and 
  headwaters 
  of 
  the 
  Charlotte 
  river; 
  in 
  the 
  northern 
  

   part 
  streams 
  rise 
  that 
  flow 
  northerly 
  into 
  the 
  Cobleskill 
  and 
  in 
  the 
  

   eastern 
  part 
  streams 
  that 
  flow 
  easterly 
  into 
  the 
  Schoharie 
  river. 
  

  

  As 
  has 
  already 
  been 
  mentioned 
  the 
  line 
  of 
  division 
  between 
  the 
  

   Hamilton 
  and 
  Sherburne 
  formations 
  crosses 
  the 
  Charlotte 
  river 
  

   near 
  Charlotteville 
  and 
  follows 
  the 
  northern 
  slope 
  of 
  the 
  valley 
  

   northeasterly 
  to 
  within, 
  perhaps, 
  one 
  mile 
  of 
  Summit. 
  Then 
  it 
  

   runs 
  southeasterly 
  along 
  the 
  Westkill 
  into 
  the 
  northern 
  part 
  of 
  

   Jefferson 
  township 
  where 
  it 
  crosses 
  the 
  stream 
  and 
  then 
  turns 
  

   northerly 
  along 
  the 
  eastern 
  side 
  of 
  the 
  valley 
  and 
  around 
  the 
  

   high 
  land 
  east 
  of 
  Summit 
  when 
  it 
  turns 
  easterly 
  and 
  follows 
  the 
  

   northern 
  slope 
  of 
  the 
  hill 
  south 
  of 
  Panther 
  creek 
  across 
  the 
  

   southern 
  part 
  of 
  Fulton 
  township

  XXVI 
  X. 
  To 
  the 
  south 
  of 
  Charlotteville 
  and 
  the 
  Charlotte 
  river 
  

   is 
  a 
  steep 
  hill 
  rising 
  nearly 
  600 
  feet 
  above 
  the 
  level 
  of 
  the 
  river, 
  

   and 
  in 
  the 
  banks 
  below 
  the 
  dam 
  at 
  Charlotteville 
  are 
  blue 
  flagging 
  

   stones 
  (X 
  1 
  ) 
  forming 
  a 
  ledge 
  some 
  eight 
  feet 
  thick. 
  There 
  are 
  

   some 
  layers 
  containing 
  plant 
  stems 
  and 
  a 
  few 
  pebbles, 
  and 
  some 
  

   partings 
  of 
  blue 
  shale. 
  The 
  dip 
  is 
  about 
  1° 
  S60° 
  W. 
  Along 
  

   the 
  banks 
  of 
  the 
  river 
  are 
  plenty 
  of 
  loose 
  stone 
  containing 
  Ham- 
  

   ilton 
  fossils 
  in 
  abundance 
  and 
  the 
  bed 
  rocks 
  resemble 
  the 
  flagging 
  

   stones 
  of 
  the 
  upper 
  part 
  of 
  the 
  Hamilton 
  in- 
  the 
  southwestern 
  

   part 
  of 
  Albany 
  co., 
  to 
  which 
  formation 
  this 
  zone 
  is 
  referred. 
  

  

  For 
  400 
  feet 
  above 
  the 
  river 
  the 
  hillside 
  is 
  covered 
  when 
  a 
  

   ledge 
  of 
  massive 
  bluish 
  gray 
  sandstone 
  (X 
  3 
  ) 
  is 
  reached 
  southeast 
  

   of 
  Charlotteville. 
  The 
  stone 
  splits 
  into 
  thin 
  flags, 
  in 
  places 
  ia 
  

   somewhat 
  crbssbedded 
  and 
  about 
  five 
  feet 
  are 
  shown. 
  No 
  fossils 
  

   were 
  found 
  and 
  it 
  is 
  apparently 
  in 
  the 
  Sherburne 
  formation. 
  

  

  On 
  the 
  top 
  of 
  the 
  hill 
  southeast 
  of

  higher 
  

   than 
  X 
  3 
  , 
  and 
  near 
  the 
  Summit-Jefferson 
  township 
  line 
  is 
  a 
  ledge 
  

   of 
  thin, 
  bluish 
  sandstone 
  to 
  arenaceous 
  shale 
  (X

  containing
