  northeast, 
  wliere 
  its 
  altitude 
  was 
  again 
  carefully 
  taken 
  with 
  a 
  level 
  

   and 
  found 
  to 
  be 
  880" 
  feet; 
  thence 
  to 
  Eatavia 
  and 
  beyond 
  to 
  

   Caledonia 
  into 
  the 
  Genesee 
  river 
  valley,^ 
  where 
  its 
  levels 
  record 
  

   on€ 
  of 
  the 
  higher 
  ancestral 
  stages 
  of 
  the 
  Genesee 
  "■' 
  lakes. 
  From 
  

   Geneseo 
  it 
  has 
  been 
  traced 
  to 
  Lima, 
  the 
  latter 
  being 
  the 
  most 
  

   easterly 
  point 
  where 
  this 
  level 
  is 
  id 
  en 
  tilled 
  by 
  Mr 
  Fairchild, 
  the 
  

   altitude 
  being 
  giv^en 
  as 
  877'^ 
  feet. 
  In 
  the 
  region 
  of 
  Lima 
  the 
  

   beach 
  phenomena 
  are 
  represented 
  by 
  spits 
  and 
  bars 
  connected 
  with 
  

   the 
  drumlius. 
  

  

  The 
  connection 
  between 
  the 
  Warren 
  waters 
  and 
  the 
  same 
  levels 
  

   in 
  the 
  central 
  jSTew 
  York 
  lake 
  region 
  was 
  to 
  the 
  northwest 
  in 
  the 
  

   Millel"'s 
  corners 
  and 
  Victor 
  kame 
  areas 
  where 
  the 
  same 
  levels 
  in 
  

   the 
  Genesee 
  valley^ 
  are 
  recorded, 
  and 
  hence 
  the 
  coalescing 
  of 
  the 
  

   Finger-lake 
  waters 
  and 
  those 
  of 
  the 
  Genesee 
  valley 
  at 
  that 
  point. 
  

  

  When 
  the 
  Warren 
  waters 
  were 
  dismembered 
  and 
  Lake 
  Iroquois 
  

   born, 
  the 
  Chicago 
  overflow 
  was 
  abandoned 
  for 
  a 
  lower 
  one 
  to 
  the 
  

   east 
  in 
  the 
  Mohawk 
  valley 
  at 
  Home, 
  New 
  York. 
  These 
  levels 
  are 
  

   also 
  seen 
  to 
  be 
  recorded 
  in 
  the 
  kame 
  areas 
  as 
  well 
  as 
  in 
  the 
  Genesee 
  

   valley 
  lakes/ 
  

  

  Lake 
  sequence 
  in 
  the 
  Finger-lake 
  valleys 
  

  

  As 
  soon 
  as 
  the 
  ice 
  commenced 
  its 
  northward 
  retreat, 
  uncovering 
  

   the 
  southern 
  di\ade 
  region 
  in 
  the 
  lake 
  valleys, 
  the 
  incipient 
  stages 
  

   of 
  the 
  highest 
  lake 
  levels 
  in 
  the 
  respective 
  valleys 
  began. 
  Of 
  these, 
  

   there 
  were 
  eight, 
  named 
  in 
  order 
  from 
  east 
  to 
  west, 
  glacial 
  lakes 
  

   Skaueateles, 
  Groton, 
  Brookton, 
  West 
  Danby, 
  Watkins, 
  Hammonds- 
  

   port, 
  Flint 
  creek 
  and 
  Naples. 
  Each 
  one 
  had 
  a 
  separate 
  outlet 
  

   leading 
  southward 
  into 
  the 
  Chemung-Susquehanna 
  drainage. 
  

  

  The 
  Watkins, 
  West 
  Danby 
  and 
  Brookton 
  stages 
  were 
  inaugurated 
  

   about 
  the 
  same 
  time. 
  The 
  West 
  Danby 
  lake 
  was 
  some 
  12 
  miles 
  

   in 
  length 
  and 
  only 
  in 
  existence 
  sufficiently 
  long 
  for 
  the 
  ice 
  to 
  with- 
  

   draw 
  from 
  the 
  divide 
  at 
  Spencer 
  Summit 
  to 
  Ithaca, 
  when 
  the 
  

   Brookton 
  and 
  West 
  Danby 
  waters 
  coalesced 
  to 
  form 
  glacial 
  lake 
  

   Ithaca 
  with 
  the 
  outlet 
  shifted 
  from 
  the 
  Summit 
  to 
  White 
  church.
