  line 
  ; 
  broad, 
  undulating 
  plains 
  of 
  till 
  witL 
  water 
  deposits 
  covering 
  

   portions 
  of 
  their 
  surfaces, 
  probably 
  thus 
  modified 
  by 
  the 
  waters 
  of 
  the 
  

   Watkins 
  level, 
  found 
  opposite 
  the 
  mouths 
  of 
  the 
  streams 
  entering 
  

   from 
  the 
  two 
  sides 
  of 
  the 
  valley. 
  Lastly, 
  evidence 
  is 
  found 
  in 
  a 
  

   very 
  strongly 
  defined 
  outlet 
  channel 
  to 
  the 
  south 
  leading 
  into 
  the 
  

   Chemung 
  river. 
  The 
  most 
  conspicuous 
  deltas 
  marking 
  this 
  level 
  are 
  

   found 
  at 
  Burdett 
  and 
  Lodi 
  on 
  the 
  east 
  side 
  of 
  the 
  Inlet 
  valley, 
  and 
  

   at 
  Watkins 
  on 
  the 
  west 
  side. 
  Other 
  markings 
  of 
  a 
  much 
  less 
  defi- 
  

   nite 
  character 
  were 
  .noted 
  at 
  Dundee 
  and 
  on 
  Yf 
  eed 
  creek 
  on 
  the 
  

   west 
  side, 
  and 
  on 
  North 
  Hector 
  and 
  Havana 
  Glen 
  streams 
  on 
  the 
  

   east 
  side 
  of 
  the 
  valley. 
  

  

  Other 
  things 
  being 
  equal, 
  glacial 
  lake 
  Watkins 
  must 
  have 
  had 
  a 
  

   longer 
  time 
  existence 
  than 
  any 
  one 
  of 
  the 
  other 
  local 
  lakes, 
  since 
  it 
  

   was 
  necessary 
  that 
  a 
  northward 
  recession 
  of 
  the 
  ice 
  amounting 
  to 
  

   some 
  35 
  miles 
  should 
  take 
  place 
  before 
  the 
  next 
  lower 
  level 
  was 
  

   established. 
  

  

  The 
  outlet 
  to 
  the 
  two 
  stages, 
  glacial 
  lakes 
  Watkins 
  and 
  Newberry, 
  

   remained 
  the 
  same 
  and 
  endured 
  through 
  and 
  to 
  the 
  close 
  of 
  the 
  

   Newberry 
  episode, 
  when 
  it 
  was 
  shifted 
  to 
  the 
  north 
  and 
  west 
  of 
  

   Canandaigua.

  Evidence 
  and 
  history 
  of 
  lake. 
  The 
  outlet 
  to 
  glacial 
  lake 
  Ham- 
  

   mondsport 
  was 
  over 
  the 
  col 
  between 
  the 
  towns 
  of 
  Hammondsport 
  

   and 
  Bath 
  with 
  an 
  elevation 
  of 
  1125 
  feet. 
  The 
  Hammondsport 
  

   stage, 
  or 
  the 
  highest 
  ancestral 
  water 
  level 
  of 
  the 
  present 
  Keuka 
  

   lake 
  which 
  is 
  718 
  feet 
  above 
  tide, 
  is 
  marked 
  by 
  two 
  large 
  and 
  con- 
  

   spicuous 
  deltas 
  just 
  above 
  the 
  town 
  of 
  Hammondsport 
  on 
  opposite 
  

   sides 
  of 
  the 
  valley. 
  The 
  one 
  on 
  the 
  east 
  side 
  at 
  Laughlin's 
  glen 
  

   has 
  an 
  elevation 
  of 
  1158 
  feet 
  above 
  tide, 
  the 
  other, 
  is 
  on 
  Glen 
  

   brook 
  which 
  enters 
  the 
  Inlet 
  valley 
  from 
  the 
  west 
  and 
  has 
  an 
  eleva- 
  

   tion 
  of 
  1123 
  feet. 
  A 
  terrace 
  on 
  the 
  same 
  stream 
  is 
  found 
  at 
  the 
  

   1018 
  foot 
  elevation 
  and 
  marks 
  an 
  intermediate 
  halt 
  between 
  the 
  

   Hammondsport 
  and 
  Newberry 
  levels.
