   INTRODUCTION

  The 
  presence 
  of 
  a 
  group 
  of 
  well-known 
  springs 
  whose 
  waters 
  

   are 
  of 
  a 
  somewhat 
  unusual 
  type, 
  has 
  long 
  given 
  prominence 
  to 
  

   the 
  region 
  about 
  Saratoga. 
  A 
  variety 
  of 
  causes 
  has 
  recently 
  

   increased 
  this 
  prominence 
  and 
  rendered 
  it 
  desirable 
  that 
  the 
  

   geology 
  of 
  the 
  region 
  should 
  undergo 
  more 
  thorough 
  investiga- 
  

   tion 
  than 
  it 
  had 
  ever 
  received, 
  in 
  the 
  hope 
  that 
  light 
  might 
  be 
  

   shed 
  upon 
  the 
  question 
  of 
  the 
  origin 
  of 
  the 
  waters 
  and 
  the 
  dura- 
  

   tion 
  of 
  the 
  'supply. 
  

  

  It 
  was 
  the 
  original 
  plan 
  to 
  include 
  in 
  this 
  report 
  the 
  geology 
  

   of 
  the 
  Broadalbin 
  quadrangle, 
  next 
  west 
  of 
  Saratoga, 
  which 
  

   was 
  assigned 
  to 
  Dr 
  W. 
  J. 
  Miller, 
  but 
  later 
  developments 
  led 
  to 
  

   the 
  abandonment 
  of 
  this 
  plan 
  and 
  Doctor 
  Miller's 
  report 
  has 
  been 
  

   published 
  separately. 
  1 
  That 
  work 
  was 
  done 
  in 
  close 
  association 
  

   with 
  our 
  own, 
  and 
  in 
  addition 
  Doctor 
  Miller 
  also 
  mapped 
  some 
  

   30 
  square 
  miles 
  in 
  the 
  extreme 
  northwest 
  corner 
  of 
  the 
  Saratoga 
  

   quadrangle. 
  This 
  service 
  is 
  emphatically 
  acknowledged 
  since 
  the 
  

   country 
  concerned 
  is 
  unsettled 
  and 
  difficult 
  of 
  access, 
  and 
  the 
  aid 
  

   was 
  rendered 
  at 
  a 
  time 
  when 
  the 
  writer 
  was 
  unable 
  to 
  engage 
  in 
  

   field 
  work 
  as 
  laborious 
  as 
  that 
  which 
  this 
  district 
  entailed. 
  With 
  

   this 
  exception, 
  Doctor 
  Ruedemann 
  and 
  myself 
  are 
  responsible 
  

   for 
  the 
  mapping. 
  Much 
  of 
  the 
  territory 
  we 
  have 
  seen 
  together.
