  The 
  outlying 
  area 
  at 
  "Wells 
  is 
  an 
  interesting 
  occurrence 
  of 
  the 
  

   formation. 
  It 
  is 
  of 
  the 
  typical, 
  light-colored 
  arenaceous 
  limestone. 
  

  

  In 
  the 
  western 
  portion 
  of 
  Saratoga 
  county 
  the 
  lower 
  member 
  

   of 
  the 
  Calciferous 
  formation 
  is 
  very 
  arenaceous 
  and 
  weathers 
  to 
  

   a 
  darker 
  color 
  than 
  usual. 
  In 
  this 
  region 
  there 
  is 
  an 
  included 
  

   bed 
  of 
  pure 
  white 
  flinty 
  quartzite 
  which 
  is 
  also 
  occasionally 
  

   observed 
  in 
  the 
  region 
  westward. 
  West 
  and 
  south 
  of 
  G-alway 
  it 
  

   has 
  a 
  thickness 
  of 
  from 
  threae 
  to 
  eight 
  feet 
  and 
  is 
  a 
  prominent 
  

   feature 
  at 
  many 
  points. 
  It 
  is 
  also 
  exposed 
  on 
  the 
  hilltop 
  half 
  a 
  

   mile 
  south 
  of 
  Mosherville. 
  Its 
  strati 
  graphic 
  position 
  is 
  about 
  

   eighty 
  feet 
  above 
  the 
  base 
  of 
  the 
  formation. 
  A 
  bed 
  of 
  similar 
  

   quartzite 
  or 
  flint, 
  of 
  dirty 
  buff 
  color, 
  was 
  also 
  observed 
  on 
  the 
  

   upper 
  road 
  from 
  Little 
  Falls 
  to 
  Manheim 
  Centre, 
  about 
  half 
  a 
  

   mile 
  east 
  of 
  the 
  Little 
  Falls 
  fault, 
  and 
  on 
  the 
  valley 
  turnpike, 
  

   two 
  and 
  a 
  half 
  miles 
  east 
  of 
  St. 
  Johnsville. 
  These 
  last-men- 
  

   tioned 
  occurrences 
  appear, 
  however, 
  to 
  be 
  in 
  a 
  somewhat 
  higher 
  

   horizon 
  than 
  those 
  of 
  the 
  Gal 
  way 
  region. 
  

  

  East 
  of 
  Gal 
  way, 
  near 
  the 
  first 
  cross 
  road, 
  three 
  feet 
  of 
  buff 
  

   calcareous 
  shaly 
  beds 
  are 
  seen 
  interbedded 
  in 
  the 
  upper 
  portion 
  

   of 
  the 
  Calciferous, 
  and 
  similar 
  beds 
  at 
  about 
  the 
  same 
  horizon 
  

   outcrop 
  just 
  north 
  of 
  the 
  upper 
  road 
  from 
  Amsterdam 
  to 
  Johns- 
  

   town 
  at 
  a 
  point 
  one 
  and 
  a 
  half 
  miles 
  due 
  north 
  of 
  Tribes 
  Hill 
  

   station. 
  

  

  The 
  f 
  ucoidal 
  layers 
  of 
  Vanuxem 
  are 
  a 
  characteristic 
  member 
  

   of 
  the 
  Calciferous 
  over 
  a 
  wide 
  area. 
  They 
  are 
  well 
  exposed 
  in 
  

   many 
  of 
  the 
  quarries 
  along 
  the 
  Mohawk, 
  where 
  they 
  are 
  worked 
  

   extensively 
  for 
  building 
  stone. 
  Their 
  character 
  and 
  distribution 
  

   have 
  been 
  described 
  with 
  care 
  by 
  Vanuxem, 
  and 
  I 
  have 
  but 
  little 
  

   to 
  add 
  to 
  his 
  statements 
  for 
  the 
  Mohawk 
  valley. 
  The 
  member 
  

   consists 
  of 
  a 
  fine-grained, 
  thick- 
  bedded 
  limestone 
  intermediate 
  in 
  

   character 
  between 
  the 
  typical 
  Calciferous 
  and 
  Birdseye 
  deposits 
  

   with 
  intercalcated 
  streakings, 
  blotchings, 
  reticulations 
  and 
  

   sprinklings 
  of 
  mixtures 
  of 
  coarse 
  sand 
  and 
  Calciferous 
  materials 
  

   of 
  light 
  color 
  in 
  greater 
  part, 
  but 
  weathering 
  dark. 
  The 
  alter- 
  

   nations 
  are 
  in 
  thin 
  layers 
  at 
  varying 
  but 
  frequent 
  intervals, 
  and 
  

   the 
  bedding 
  of 
  the 
  fine-grained 
  material 
  is 
  usually 
  more 
  or 
  less 
  

   disjointed 
  into 
  a 
  partial 
  breccia. 
  The 
  coarse 
  materials 
  are 
  dis- 
  

   posed 
  in 
  forms 
  suggesting 
  fucoids, 
  and 
  this 
  resemblance 
  has 
  

   given 
  the 
  name 
  to 
  the 
  member. 
  Fossils 
  are 
  usually 
  present 
  and
