  Emmons 
  referred 
  frequently 
  to 
  the 
  Schoharie 
  valley 
  region 
  

   and 
  in 
  describing 
  this 
  route 
  to 
  the 
  Oatskills 
  said, 
  " 
  The 
  whole 
  

   New 
  York 
  system 
  is 
  traversed 
  by 
  this 
  route, 
  and 
  it 
  leads 
  up 
  a 
  

   beautiful 
  valley, 
  on 
  the 
  sides 
  of 
  which 
  the 
  strata 
  are 
  finely 
  

   exposed 
  in 
  receding 
  terraces 
  or 
  steep 
  escarpments. 
  Beautiful 
  

   cascades 
  and 
  splendid 
  scenery 
  gratify 
  the 
  sight 
  at 
  every 
  turn; 
  

   while 
  to 
  the 
  geologist 
  the 
  succession 
  and 
  stratigraphical 
  arrange- 
  

   ment 
  is 
  so 
  clear 
  and 
  satisfactory, 
  that 
  all 
  doubts 
  are 
  dispelled. 
  

   The 
  advantages 
  of 
  this 
  route 
  are 
  decisive, 
  in 
  consequence 
  of 
  the 
  

   fine 
  field 
  at 
  Schoharie, 
  where 
  the 
  succession 
  is 
  over 
  a 
  complete 
  

   division 
  of 
  the 
  Helderberg 
  rocks; 
  the 
  Erie 
  division 
  is 
  full 
  and 
  

   complete 
  also, 
  and 
  may 
  be 
  observed 
  first 
  in 
  the 
  rounded 
  hills 
  

   about 
  Schoharie 
  village, 
  dipping 
  in 
  the 
  direction 
  of 
  the 
  route 
  

   of 
  the 
  creek; 
  and 
  the 
  succeeding 
  members 
  slowly 
  follow 
  each 
  

   other, 
  till, 
  finally, 
  at 
  Gilboa, 
  the 
  Catskill 
  rocks 
  are 
  found 
  at 
  the 
  

   base 
  of 
  the 
  high 
  ranges 
  which 
  have 
  hedged 
  -in 
  the 
  creek 
  for 
  

   25 
  miles.

  The 
  rocks 
  along 
  the 
  Schoharie 
  river 
  from 
  Gilboa 
  to 
  Middle-

  were 
  also 
  measured 
  by

   1873

  of

  Hall

   something
