  distinct 
  halts 
  between 
  the 
  two 
  definitely 
  defined 
  stages. 
  This 
  con- 
  

   dition 
  was 
  not 
  persistent 
  throughout 
  every 
  stage, 
  as 
  some 
  of 
  the 
  

   earlier 
  ones 
  in 
  the 
  local 
  lakes 
  strongly 
  suggest 
  a 
  rapid 
  falling 
  in 
  

   the 
  waters. 
  

  

  A 
  study 
  of 
  the 
  terrace 
  elevations 
  seems 
  to 
  indicate 
  a 
  general 
  north- 
  

   ward 
  rise 
  in 
  the 
  shore-lines 
  of 
  the 
  different 
  lake 
  stages, 
  which 
  sug- 
  

   gests 
  a 
  differential 
  uplift 
  in 
  that 
  direction, 
  since 
  the 
  desertion 
  of 
  the 
  

   levels 
  by 
  the 
  waters. 
  The 
  figures 
  furthermore, 
  indicate 
  not 
  a 
  uni- 
  

   form 
  uplift, 
  but 
  rather 
  a 
  kind 
  of 
  warping, 
  better 
  described 
  as 
  

   *' 
  buckling 
  " 
  in 
  the 
  gradient, 
  shown 
  in 
  t^iie 
  unequal 
  distances 
  between 
  

   the 
  same 
  levels 
  in 
  different 
  places. 
  Also, 
  the 
  gradient 
  is 
  not 
  the 
  

   same 
  for 
  any 
  two 
  levels.
