  in 
  the 
  region 
  now 
  under 
  consideration. 
  Typical 
  crystalline 
  

   limestone 
  has 
  been 
  found 
  in 
  rather 
  small 
  quantities 
  at 
  the 
  head 
  of 
  

   Fourth 
  lake, 
  on 
  the 
  north 
  shore 
  of 
  Sixth 
  lake, 
  on 
  the 
  island 
  in 
  

   Seventh 
  lake, 
  on 
  the 
  west 
  shore 
  and 
  the 
  island 
  of 
  Eighth 
  lake, 
  on 
  

   Lime 
  Kiln 
  creek 
  and 
  on 
  the 
  east 
  shore 
  of 
  Raquette 
  lake. 
  Rusty 
  

   gneisses 
  like 
  those 
  of 
  the 
  limestone 
  formation 
  but 
  not 
  accom- 
  

   panied 
  by 
  any 
  actual 
  limestone 
  have 
  been 
  found 
  at 
  two 
  points 
  

   between 
  Seventh 
  lake 
  and 
  Mohican 
  lake, 
  on 
  Lime 
  Kiln 
  lake 
  and 
  

   at 
  Moose 
  River. 
  

  

  In 
  view 
  of 
  the 
  fact 
  that 
  the 
  limestone 
  on 
  account 
  of 
  its 
  ready 
  

   solubility 
  is 
  apt 
  to 
  be 
  very 
  inconspicuous, 
  and 
  that 
  only 
  a 
  rapid 
  

   reconnaissance 
  of 
  the 
  region 
  was 
  made, 
  it 
  is 
  certain 
  that 
  other 
  

   limestone 
  areas 
  occur 
  and 
  that 
  it 
  is 
  by 
  no 
  means 
  a 
  rare 
  rock. 
  

  

  Perhaps 
  the 
  most 
  typical 
  development 
  of 
  the 
  limesone 
  is 
  on 
  

   Lime 
  Kiln 
  creek 
  southeast 
  of 
  Little 
  Moose 
  lake 
  near 
  the 
  logging 
  

   dam. 
  The 
  limestone 
  here 
  is 
  coarse 
  and 
  fairly 
  pure 
  though 
  pene- 
  

   trated 
  by 
  a 
  great 
  deal 
  of 
  pegmatite. 
  Rusty 
  gneiss 
  is 
  present, 
  

   much 
  contorted, 
  and 
  the 
  whole 
  association 
  and 
  structure 
  is 
  pre- 
  

   cisely 
  like 
  that 
  of 
  the 
  limestone 
  belts 
  of 
  St 
  Lawrence 
  co. 
  

   At 
  the 
  logging 
  dam 
  there 
  is 
  exposed 
  a 
  well 
  banded, 
  fine 
  gray 
  

   gneiss 
  which 
  would 
  be 
  suspected 
  of 
  belonging 
  to 
  the 
  limestone 
  

   series, 
  even 
  if 
  the 
  limestone 
  itself 
  did 
  not 
  appear 
  in 
  the 
  immedi- 
  

   ate 
  vicinity. 
  

  

  About 
  half 
  a 
  mile 
  down 
  stream 
  from 
  this 
  point 
  at 
  the 
  mouth 
  

   of 
  a 
  small 
  brook 
  there 
  is 
  an 
  outcrop 
  of 
  mica 
  schist 
  and 
  a 
  highly 
  

   quartzose 
  rock, 
  the 
  two 
  apparently 
  bedded 
  rocks 
  of 
  sedimentary 
  

   origin. 
  Thin 
  section 
  shows 
  these 
  rocks 
  to 
  be, 
  the 
  one 
  of 
  true 
  

   mica 
  schist, 
  the 
  other 
  an 
  impure 
  quartzite 
  containing 
  much 
  

   pyroxene, 
  zircon, 
  etc. 
  No 
  equally 
  good 
  examples 
  of 
  these 
  two 
  

   types 
  of 
  metamorphosed 
  sediments 
  have 
  been 
  seen 
  by 
  the 
  writer 
  

   anywhere 
  else 
  in 
  the 
  Adirondack 
  region. 
  The 
  presence 
  of 
  the 
  

   limestone 
  five 
  or 
  six 
  hundred 
  feet 
  up 
  the 
  brook, 
  showing 
  the 
  

   same 
  strike 
  and 
  dip 
  (n40°e, 
  45°n) 
  as 
  do 
  the 
  schist 
  and 
  quartzite, 
  

   tends 
  to 
  substantiate 
  the 
  conclusions 
  as 
  to 
  the 
  sedimentary 
  origin 
  

   of 
  the 
  latter. 
  The 
  facts 
  observed 
  in 
  this 
  vicinity 
  indicate 
  the
