  lower 
  succession 
  is 
  found, 
  extending 
  in 
  some 
  cases 
  within 
  a 
  few 
  

   miles 
  of 
  the 
  lake 
  outlets. 
  They 
  can 
  be 
  traced 
  from 
  the 
  deltas 
  now 
  

   forming 
  opposite 
  the 
  stream 
  mouths 
  entering 
  the 
  lakes, 
  up 
  to 
  the 
  

   Warren 
  level. 
  They 
  have 
  not 
  lost 
  any 
  of 
  their 
  distinctive 
  delta 
  

   characteristics, 
  and 
  many 
  of 
  them 
  stand 
  out 
  as 
  conspicuously 
  and 
  

   are 
  as 
  large 
  and 
  strongly 
  developed 
  as 
  any 
  found 
  among 
  the 
  higher 
  

   levels. 
  (Figure 
  28). 
  While 
  nearly 
  all 
  of 
  these 
  have 
  been 
  measured^ 
  

   the 
  time 
  available 
  has 
  been 
  insufficient 
  to 
  study 
  and 
  work 
  out 
  their 
  

   correlation 
  with 
  one 
  another 
  and 
  the 
  corresponding 
  drainage 
  chan- 
  

   nels. 
  1^0 
  attempt 
  therefore, 
  will 
  be 
  made 
  to 
  work 
  out 
  the 
  

   different 
  stages 
  among 
  them 
  in 
  the 
  present 
  paper, 
  but 
  doubtless 
  

   they 
  will 
  form 
  a 
  fitting 
  theme 
  for 
  some 
  future 
  worker, 
  after 
  which 
  

   the 
  complete 
  Finger-lake 
  history 
  may 
  be 
  written. 
  

  

  On 
  Lake 
  Seneca 
  the 
  lower 
  levels 
  have 
  been 
  noted 
  within 
  three 
  to 
  

   five 
  miles 
  of 
  the 
  lake 
  outlet 
  on 
  the 
  most 
  northerly 
  tributaries 
  enter- 
  

   ing 
  from 
  the 
  west 
  side. 
  The 
  most 
  northerly 
  trace 
  of 
  the 
  lower 
  

   terraces 
  on 
  the 
  west 
  side 
  of 
  Cayuga 
  lake 
  was 
  found 
  on 
  the 
  stream 
  

   entering 
  at 
  Sheldrake 
  point, 
  some 
  21 
  miles 
  north 
  of 
  Ithaca. 
  

   It 
  is 
  but 
  a 
  weakly 
  defined 
  terrace 
  occurring 
  on 
  the 
  north 
  side 
  of 
  the 
  

   stream 
  at 
  an 
  elevation 
  of 
  488 
  feet 
  above 
  tide 
  and 
  marks 
  the 
  site 
  of 
  

   a 
  cemetery. 
  

  

  Some 
  of 
  the 
  lower 
  terraces 
  are 
  as 
  large 
  and 
  strongly 
  defined 
  as 
  

   any 
  among 
  the 
  higher 
  levels, 
  which 
  probably 
  indicates 
  for 
  the 
  

   former 
  a 
  rather 
  longer 
  and 
  more 
  protracted 
  halt 
  in 
  the 
  waters. 
  So 
  

   far 
  as 
  study 
  was 
  possible 
  the 
  conditions 
  of 
  water 
  level, 
  etc., 
  were 
  

   interpreted 
  as 
  being 
  the 
  same 
  as 
  worked 
  out 
  for 
  the 
  terraces 
  mark- 
  

   ing 
  similar 
  levels 
  among 
  the 
  higher 
  stages. 
  

  

  Among 
  the 
  lower 
  levels 
  in 
  the 
  general 
  lake 
  succession 
  a 
  change 
  in 
  

   the 
  waters 
  took 
  place, 
  whereby 
  they 
  were 
  partly 
  dismembered. 
  The 
  

   exact 
  time 
  of 
  this 
  change 
  has 
  not 
  yet 
  been 
  worked 
  out, 
  but 
  it 
  hap- 
  

   pened 
  after 
  the 
  Warren 
  levels 
  were 
  abandoned, 
  and 
  probably 
  not 
  

   until 
  the 
  shifting 
  of 
  the 
  outlet 
  of 
  the 
  Great 
  Lakes 
  to 
  Rome 
  and 
  

   the 
  Thousand 
  Islands 
  by 
  way 
  of 
  the 
  St 
  Lawrence 
  river. 
  It 
  is 
  

   possible 
  that 
  during 
  a 
  part, 
  if 
  not 
  all 
  of 
  the 
  time, 
  during 
  which 
  the 
  

   Great 
  Lakes 
  were 
  draining 
  through 
  the 
  Mohawk 
  at 
  Rome, 
  the 
  

   waters 
  of 
  the 
  Finger-lakes, 
  or 
  at 
  least 
  some 
  of 
  them, 
  were 
  still 
  

   united 
  with 
  and 
  formed 
  a 
  part 
  of 
  that 
  system.
