  not 
  probable, 
  however, 
  that 
  these 
  fragments 
  came 
  from 
  this 
  part 
  

   of 
  the 
  hill, 
  but 
  they 
  were 
  undoubtedly 
  left 
  by 
  the 
  ice 
  sheet 
  near 
  

   the 
  summit 
  of 
  Moheganter 
  hill. 
  On 
  a 
  stone 
  wall 
  in 
  this 
  vicinity 
  

   large 
  flat 
  blocks 
  of 
  sandstone 
  were 
  seen 
  which 
  contained 
  the 
  fol- 
  

   lowing 
  species, 
  the 
  first 
  one 
  occurring 
  in 
  large 
  numbers:

  From 
  this 
  last 
  outcrop 
  to 
  the 
  top 
  of 
  the

  the 
  corners,

  section

  D, 
  is 
  40 
  feet 
  which 
  makes 
  it 
  1440 
  feet 
  

   above 
  the 
  level 
  of 
  the 
  Schoharie 
  river 
  at 
  its 
  base. 
  The 
  baromet- 
  

   ric 
  section 
  from 
  Middleburg 
  village 
  up 
  the 
  Little 
  Schoharie 
  and 
  

   the 
  eastern 
  slope 
  of 
  Moheganter 
  hill 
  (XXXVII 
  D) 
  to 
  the 
  road 
  cor- 
  

   ners 
  made 
  it 
  1500 
  feet; 
  so 
  in 
  the 
  elevations 
  there 
  is 
  probably 
  not 
  a 
  

   very 
  serious 
  error 
  in 
  the 
  case 
  of 
  either 
  section. 
  This 
  section 
  is 
  

   here 
  represented 
  diagrammatically. 
  On 
  account 
  of 
  the 
  covered 
  

   slope 
  it 
  is 
  not 
  possible 
  to 
  indicate 
  closely 
  the 
  line 
  of 
  division 
  be- 
  

   tween 
  the 
  Hamilton 
  and 
  Sherburne 
  formations. 
  There 
  are 
  at 
  

   least 
  755 
  feet 
  of 
  rocks 
  above 
  the 
  level 
  of 
  the 
  Schoharie 
  river 
  be- 
  

   longing 
  in 
  the 
  Hamilton 
  and 
  probably 
  part 
  of 
  the 
  succeeding 
  

   covered 
  240 
  feet 
  belongs 
  in 
  the 
  same 
  formation. 
  The 
  240 
  feet 
  

   above 
  the 
  covered 
  zone 
  to 
  the 
  base 
  of 
  the 
  heavy 
  red 
  sandstone 
  is 
  

   referred 
  to 
  the 
  Sherburne 
  and 
  Ithaca 
  formations, 
  the 
  thickness 
  of 
  

   which 
  probably 
  should 
  be 
  increased 
  by 
  a 
  portion 
  of 
  the 
  under- 
  

   lying 
  covered 
  zone. 
  The 
  rocks 
  from 
  the 
  base 
  of 
  the 
  red 
  sand- 
  

   stone 
  (C 
  9 
  ) 
  to 
  the 
  summit 
  of 
  the 
  hill 
  are 
  referred 
  to 
  the 
  Oneonta 
  

   formation. 
  It 
  is 
  clearly 
  recognized 
  that 
  to 
  the 
  west 
  of 
  the 
  Scho- 
  

   harie 
  river, 
  rocks 
  at 
  this 
  horizon 
  are 
  not 
  red 
  and 
  are 
  not 
  called 
  

   Oneonta 
  but 
  are 
  referred 
  to 
  the 
  Ithaca 
  formation. 
  A 
  little 
  

   farther 
  east, 
  however, 
  along 
  the 
  Schoharie-Albany 
  co. 
  line 
  

   and 
  to 
  the 
  eastward, 
  the 
  red 
  rocks 
  near 
  this 
  horizon 
  and 
  still 
  

   lower 
  have 
  been 
  mapped 
  and 
  correlated 
  with 
  the 
  Oneonta 
  forma- 
  

   tion. 
  In 
  that 
  region 
  it 
  is 
  impossible 
  to 
  follow 
  any 
  line 
  of 
  di- 
  

   vision 
  between 
  the 
  Ithaca 
  and 
  Oneonta 
  formations, 
  for 
  the
