  its 
  outlet, 
  draining 
  northeast 
  to 
  the 
  Hudson, 
  and 
  

   Stony 
  creek, 
  flowing 
  southwest 
  to 
  the 
  Sacondaga. 
  The 
  Sacondaga 
  

   river 
  describes 
  a 
  very 
  peculiar 
  course 
  for 
  after 
  the 
  junction 
  of 
  

   its 
  two 
  branches, 
  one 
  from 
  the 
  northeast 
  and 
  the 
  other 
  from 
  the 
  

   northwest, 
  it 
  turns 
  back 
  in 
  the 
  edge 
  of 
  Fulton 
  co. 
  and 
  takes 
  a 
  

   northeast 
  course 
  across 
  Saratoga 
  co. 
  into 
  the 
  Hudson 
  at 
  Had- 
  

   ley. 
  This 
  is 
  so 
  striking 
  that 
  on 
  the 
  map 
  it 
  suggests 
  a 
  reversal 
  of 
  

   the 
  drainage.

  order 
  so 
  far 
  as 
  the 
  

   field 
  work 
  for 
  1897 
  affected 
  them. 
  In 
  1898 
  the

  Topography. 
  Bolton 
  lies 
  along 
  the 
  west 
  shore 
  of 
  Lake 
  George, 
  

   about 
  midway 
  of 
  the 
  lake, 
  and 
  it 
  consists 
  chiefly 
  of 
  one 
  large 
  

   and 
  one 
  smaller 
  ridge, 
  between 
  Lake 
  George 
  and 
  the 
  valley 
  

   of 
  the 
  Schroon 
  river. 
  - 
  The 
  smaller 
  ridge 
  is 
  cut 
  off 
  from 
  the 
  main 
  

   one 
  by 
  Northwest 
  bay 
  and 
  its 
  inlet, 
  the 
  brook 
  of 
  the 
  same 
  name. 
  

   It 
  is 
  known 
  in 
  general 
  as 
  Tongue 
  mountain, 
  and 
  its 
  northern 
  

   peak, 
  Fivemile 
  mountain, 
  is 
  the 
  highest 
  part 
  of 
  the 
  township, 
  

   2258 
  feet. 
  There 
  is 
  little 
  doubt 
  that 
  it 
  is 
  a 
  faulted 
  block. 
  It 
  

   is 
  somewhat 
  steeper 
  towards 
  the 
  lake, 
  or 
  to 
  the 
  southeast, 
  which 
  

   is 
  the 
  reverse 
  of 
  the 
  usual 
  relation 
  but 
  it 
  may 
  be 
  caused 
  by 
  a 
  

   normal 
  fault 
  with 
  a 
  dip 
  to 
  the 
  east, 
  whereas 
  in 
  previous 
  cases 
  the 
  

   faults 
  dipped 
  west. 
  The 
  main 
  ridge, 
  forming 
  the 
  body 
  of 
  the 
  

   township, 
  consists 
  of 
  a 
  rather 
  broad 
  aggregate 
  of 
  minor 
  eleva- 
  

   tions, 
  of 
  which 
  the 
  highest 
  is 
  scant 
  2000 
  feet 
  and 
  the 
  general 
  run 
  

   is 
  about 
  1500. 
  Indian 
  brook 
  lies 
  in 
  a 
  valley 
  of 
  moderate 
  size, 
  and 
  

   Trout 
  lake 
  marks 
  another 
  depression 
  with 
  a 
  north 
  and 
  south 
  axis. 
  

  

  Series 
  1. 
  Our 
  collections 
  from 
  Bolton 
  are 
  not 
  as 
  complete 
  as 
  

   could 
  be 
  desired 
  but 
  our 
  observations 
  embrace 
  in 
  the 
  way 
  of 
  

   reconnaissance 
  all 
  but 
  the 
  extreme 
  southern 
  limit 
  of 
  the 
  town. 
  

   The 
  commonest 
  form 
  of 
  gneiss 
  is 
  that 
  derived 
  from 
  the 
  dark 
  

   green 
  augite-syenites 
  which 
  were 
  described 
  quite 
  fully 
  under 
  

   Whitehall 
  and 
  were 
  called 
  the 
  Whitehall 
  type. 
  They 
  consist 
  of
