  a. 
  At 
  this 
  place 
  the 
  gravel 
  is 
  cemented 
  by 
  car 
  

   bonate 
  of 
  lime, 
  masses 
  of 
  which 
  have 
  fallen 
  at 
  b. 
  

  

  The 
  coarser 
  materials 
  of 
  the 
  gravel 
  hills 
  near 
  Albany 
  are 
  chiefly 
  

   of 
  the 
  conglomerate 
  of 
  the 
  Hudson 
  river 
  group 
  and 
  conglomerates 
  

   and 
  jaspers 
  of 
  the 
  Quebec 
  group 
  (as 
  shown 
  in 
  Bald 
  mountain). 
  

   Massive 
  quartz, 
  white 
  or 
  yellow 
  (Potsdam 
  ?), 
  is 
  commonly 
  met 
  

   with, 
  and 
  in 
  some 
  hills 
  near 
  the 
  Mohawk 
  seem 
  even 
  to 
  predomi- 
  

   nate. 
  They 
  are 
  the 
  best 
  worn 
  of 
  all 
  the 
  pebbles 
  ; 
  but 
  the 
  boulders 
  

   generally 
  are 
  not 
  so 
  well 
  rounded 
  as 
  those 
  turned 
  by 
  pot-holes. 
  

  

  Drift

  — 
  In 
  Saratoga, 
  the 
  direction 
  of 
  drift 
  striae 
  is 
  

   N.

  E. 
  They 
  are 
  well 
  preserved 
  on 
  the 
  calciferous 
  sandrock.

  Cliffs. 
  — 
  A 
  later 
  examination 
  of 
  the 
  cliff 
  near 
  the 
  

   company's 
  dam 
  (east 
  side) 
  calls 
  for 
  a 
  limitation 
  of 
  statements 
  

   made 
  on 
  pp. 
  135 
  and 
  137. 
  Near 
  the 
  dam 
  is 
  a 
  portion 
  of 
  some 
  fifty 
  

   rods 
  that 
  is 
  as 
  rugged, 
  nearly 
  as 
  steep, 
  and 
  apparently 
  as 
  inhos- 
  

   pitable 
  to 
  trees, 
  as 
  the 
  cove 
  above 
  the 
  falls. 
  

  

  Note 
  B. 
  Slips. 
  — 
  A 
  half 
  mile 
  below 
  Crescent 
  are 
  some 
  slips 
  that 
  

   dip 
  N. 
  W. 
  instead 
  of 
  S. 
  E., 
  as 
  do 
  those 
  below 
  the 
  fall. 
  They 
  make 
  

   so. 
  ne 
  curious 
  combinations 
  that 
  I 
  have 
  sketched 
  (tig. 
  23). 
  It 
  is 
  

  

  doubtful 
  whether 
  b 
  continues 
  a 
  or 
  c, 
  

   and 
  not 
  unlikely 
  that 
  it 
  has 
  served 
  

   each 
  in 
  turn. 
  Each 
  of 
  the 
  three 
  

   shows 
  slides 
  in 
  widely 
  different 
  

   directions, 
  but 
  the 
  upper 
  surface 
  of 
  

   the 
  quartz 
  filling 
  of 
  each 
  is 
  marked 
  

   with 
  striae, 
  N. 
  40° 
  W., 
  which 
  is 
  sub- 
  

   stantially 
  the 
  direction 
  of 
  the 
  plane 
  

   of 
  the 
  section 
  that 
  the 
  drawing 
  represents. 
  The 
  direction 
  of 
  e 
  

   was 
  not 
  observed, 
  but 
  in 
  / 
  the 
  motion 
  was 
  towards 
  or 
  from 
  the 
  

   junction. 
  A 
  continuation 
  off 
  may 
  exist 
  somewhere 
  on 
  the 
  lower
