  directly 
  beneath 
  the 
  Chazy. 
  Where 
  nearest 
  together 
  the 
  dip 
  of 
  

   the 
  former 
  is 
  five 
  degrees 
  to 
  north 
  fifty 
  degrees 
  east, 
  and 
  of 
  the 
  

   latter 
  ten 
  degrees 
  to 
  north 
  sixty 
  degrees 
  east, 
  and 
  the 
  Chazy 
  beds 
  

   exposed 
  are 
  by 
  no 
  means 
  the 
  basal 
  beds, 
  so 
  it 
  is 
  possible 
  there 
  is 
  

   some 
  dislocation 
  here. 
  These 
  beds 
  have 
  been 
  mapped 
  separately 
  

   as 
  either 
  Chazy 
  or 
  Calciferous, 
  pending 
  further 
  investigation 
  of 
  

   their 
  position 
  and 
  relationships. 
  In 
  the 
  central 
  portion 
  of 
  Chazy 
  

   nearly 
  the 
  entire 
  width 
  of 
  the 
  township 
  is 
  occupied 
  by 
  clearly 
  

   marked 
  Chazy 
  beds. 
  A 
  short 
  distance 
  to 
  the 
  south 
  they 
  run 
  out 
  

   except 
  at 
  the 
  extreme 
  east, 
  and 
  their 
  place 
  is 
  taken 
  by 
  these 
  

   unfossiliferous 
  beds 
  which 
  are 
  the 
  only 
  ones 
  that 
  outcrop 
  in 
  

   Beekmantown 
  between 
  the 
  Calciferous 
  and 
  the 
  Trenton 
  along 
  the 
  

   lake 
  shore, 
  outcrops 
  of 
  the 
  two 
  series 
  lying 
  quite 
  close 
  to 
  

   each 
  other. 
  

  

  Chazy 
  limestone. 
  — 
  The 
  Chazy 
  limestone 
  is 
  excellently 
  and 
  nearly 
  

   completely 
  shown 
  in 
  Chazy 
  township, 
  and 
  on 
  Yalcour 
  Island 
  ,. 
  

   and 
  less 
  completely 
  at 
  Bluff 
  Point. 
  Careful 
  detailed 
  sections 
  at 
  

   Chazy 
  village 
  and 
  on 
  Yalcour 
  Island, 
  have 
  been 
  published 
  by 
  

   Messrs. 
  Brainerd 
  and 
  SeeLy, 
  and 
  were 
  of 
  great 
  assistance 
  to 
  me.* 
  

   They 
  have 
  subdivided 
  the 
  formation 
  into 
  lower, 
  middle 
  and 
  upper 
  

   Chazy, 
  recognizable 
  readily 
  by 
  their 
  fossils, 
  and 
  in 
  general 
  by 
  

   their 
  lithological 
  character, 
  and 
  with 
  fossils 
  so 
  numerous 
  in 
  beds 
  

   not 
  widely 
  apart 
  vertically, 
  that 
  with 
  fair 
  exposures 
  their 
  recog- 
  

   nition 
  is 
  a 
  simple 
  matter. 
  

  

  Outcrops 
  of 
  the 
  Chazy 
  limestone 
  in 
  Champlain 
  township 
  are 
  of 
  

   infrequent 
  occurrence, 
  but 
  sufficiently 
  scattered 
  to 
  permit 
  fairly 
  

   accurate 
  mapping. 
  These 
  outcrops 
  are 
  all 
  of 
  the 
  middle 
  Chazy 
  

   (the 
  Maclurea 
  beds), 
  and 
  none 
  of 
  the 
  upper 
  and 
  lower 
  divisions 
  

   could 
  be 
  found. 
  If 
  the 
  Maclurea 
  beds 
  in 
  Smith's 
  quarry,, 
  

   southwest 
  of 
  Eouse's 
  Point, 
  were 
  prolonged 
  along 
  the 
  strike 
  

   they 
  would 
  almost 
  come 
  in 
  contact 
  with 
  the 
  easternmost 
  

   exposure 
  of 
  Calciferous 
  on 
  the 
  Central 
  Y< 
  rniont 
  railroad 
  

   west 
  of 
  Eouse's 
  Point 
  and 
  one 
  mile 
  north 
  of 
  Smith's 
  quarry, 
  

   so 
  that 
  here 
  apparently 
  the 
  lower 
  division 
  of 
  the 
  Chazy 
  and 
  

   a 
  considerable 
  portion 
  of 
  the 
  upper 
  Calciferous 
  are 
  lacking, 
  and 
  

   this 
  on 
  the 
  prolongation 
  of 
  the 
  line 
  along 
  which, 
  further 
  south- 
  

   west, 
  the 
  Potsdam 
  and 
  Chazy 
  are 
  brought 
  together. 
  In 
  Chazy 
  

   township 
  the 
  Chazy 
  limestone 
  is 
  magnificently 
  shown.
