  As 
  before 
  mentioned 
  (p. 
  r26) 
  this 
  outcrop 
  is 
  within 
  a 
  quarter 
  of 
  

   a 
  mile 
  of 
  the 
  outcrop 
  of 
  ciystalline 
  rock. 
  

  

  One 
  mile 
  west 
  of 
  Hawkinsville, 
  in 
  a 
  field 
  west 
  of 
  the 
  turnpike, 
  a 
  

   ledge 
  was 
  found 
  (139C) 
  three 
  feet 
  thick, 
  gray, 
  very 
  crystalline 
  and 
  

   abounding 
  in 
  Dahnanella 
  testudinaria^ 
  gastropods 
  and 
  bryozoa. 
  

  

  Protowarthia 
  cancellata 
  Isotelus 
  gig 
  as 
  

  

  Boonville 
  and 
  Leyden. 
  As 
  before 
  stated 
  a 
  non-continuous 
  sec- 
  

   tion 
  is 
  cut 
  by 
  Sugar 
  river 
  from 
  Boonville 
  to 
  Leyden. 
  The 
  highest 
  

   beds 
  of 
  this 
  section 
  are 
  seen 
  at 
  the 
  Talcottville 
  quarries 
  (1410), 
  

   where 
  62 
  feet 
  of 
  encrinal 
  Trenton 
  layers 
  occur, 
  dipping 
  3°S 
  

   20° 
  W. 
  (Fig. 
  5) 
  The 
  layers 
  are 
  6-15 
  inches 
  thick, 
  with 
  thin, 
  

   shaly 
  partings, 
  the 
  latter 
  very 
  fossiliferous. 
  Orthids 
  occur 
  in 
  great 
  

   abundance, 
  one 
  layer 
  8 
  to 
  10 
  feet 
  below 
  the 
  top 
  of 
  the 
  mass 
  

   being 
  filled 
  with 
  a 
  large 
  form 
  of 
  Dalmanella 
  subaeqitata. 
  

  

  UTICA-HUDSON 
  (FRANKFORT 
  SI^ATE) 
  

  

  On 
  a 
  branch 
  of 
  Sugar 
  river 
  just 
  east 
  of 
  the 
  road 
  from 
  Talcottville 
  

   to 
  Constableville 
  the 
  Utica 
  boundary 
  was 
  established. 
  The 
  river 
  

   between, 
  follows 
  an 
  older 
  river 
  bottom 
  without 
  outcrop. 
  At 
  the 
  

   place 
  referred 
  to, 
  the 
  edge 
  of 
  a 
  shaly 
  ledge 
  about 
  2J 
  feet 
  thick 
  

   appears 
  (141 
  A) 
  which, 
  except 
  for 
  the 
  extent 
  which 
  it 
  covers 
  might 
  

   be 
  considered 
  a 
  large 
  boulder. 
  For 
  the 
  most 
  part 
  it 
  is 
  brown 
  and 
  

   decomposed, 
  but 
  fresher 
  fragments 
  contain 
  Triarthrus 
  hecki^ 
  Orthis 
  

   and 
  a 
  small 
  Orthoceras^ 
  which 
  also 
  occurs 
  in 
  the 
  shales 
  at 
  Frankfort. 
  

  

  The 
  Black 
  river 
  formation 
  escarpment 
  begins 
  a 
  few 
  hundred 
  

   yards 
  east 
  of 
  the 
  gabbro, 
  but 
  with 
  no 
  observed 
  contact, 
  and 
  in 
  gen- 
  

   eral, 
  for 
  some 
  miles 
  parallels 
  the 
  railroad 
  and 
  canal. 
  The 
  gabbro 
  

   appears 
  west 
  of 
  the 
  railroad 
  at 
  intervals, 
  all 
  the 
  way 
  from 
  

   Lyon 
  Falls 
  to 
  Glendale, 
  and 
  in 
  more 
  scattered 
  outcrops 
  over 
  

   half 
  way 
  between 
  Martinsburg 
  station 
  and 
  Lowville. 
  The 
  

   first 
  Trenton 
  outcrop 
  on 
  the 
  railroad 
  is 
  in 
  a 
  culvert 
  one 
  mile 
  

   north 
  of 
  Lowville. 
  Beyond 
  this 
  the 
  railroad 
  follows 
  a 
  sand-plain 
  

   until 
  Carthage 
  is 
  reached. 
  The 
  Trenton 
  strip 
  is 
  therefore 
  narrower 
  

   than 
  has 
  been 
  supposed, 
  and 
  the 
  white 
  area 
  east 
  of 
  Lowville 
  on 
  

   Prof. 
  Hall's 
  map 
  ('94) 
  should 
  be 
  colored 
  as 
  Precambrian. 
  It 
  

   appears 
  that 
  the 
  contact 
  between 
  the 
  crystallines 
  and 
  the 
  sediraen- 
  

   taries 
  is 
  in 
  general 
  a 
  little 
  west 
  of 
  the 
  railroad, 
  and 
  from 
  the 
  abrupt
