  These 
  waters 
  were 
  heavily 
  laden 
  with 
  the 
  

   material 
  transported 
  by 
  and 
  to 
  the 
  glacier 
  front, 
  which 
  marks 
  the 
  

   very 
  heavy 
  and 
  extensive 
  deposits 
  laid 
  down 
  throughout 
  the 
  greater 
  

   lengths 
  of 
  the 
  valleys 
  as 
  valley-trains. 
  Such 
  deposits 
  are 
  rarely 
  seen 
  

   in 
  a 
  higher 
  degree 
  of 
  development. 
  The 
  divides 
  are 
  not 
  high 
  and 
  

   sharply 
  defined, 
  but 
  are 
  very 
  low 
  and 
  broad, 
  and 
  replaced 
  almost 
  

   wholly 
  by 
  extensive 
  swamp 
  areas. 
  From 
  these, 
  the 
  head 
  waters 
  of 
  

   the 
  north 
  and 
  south 
  flowing 
  streams 
  have 
  their 
  origin, 
  and 
  meander 
  

   in 
  a 
  most 
  sluggish 
  manner.

  The

  is 
  marked 
  by 
  an 
  ahnost 
  

   continuous 
  gravel 
  ridge 
  extending 
  across 
  the 
  valley, 
  rising 
  from 
  

   75 
  to 
  100 
  feet 
  and 
  more 
  above 
  the 
  overflow 
  channel, 
  which 
  is 
  

   at 
  the 
  head 
  of 
  a 
  pine 
  forest 
  near 
  the 
  eastern 
  side 
  of 
  the 
  valley.

  The 
  Lehigh 
  Yalley 
  railroad 
  has 
  cut 
  through 
  the 
  

   ridge 
  a 
  little 
  west 
  of 
  the 
  middle 
  part 
  of 
  the 
  valley 
  with 
  an 
  ele- 
  

   vation 
  of 
  1074 
  feet. 
  The 
  bottom 
  of 
  the 
  overflow 
  channel 
  at 
  the 
  

   head 
  of 
  the 
  forest 
  is 
  35 
  feet 
  lower 
  than 
  the 
  railroad 
  elevation, 
  

   giving 
  therefore 
  for 
  this 
  channel 
  an 
  elevation 
  of 
  1039 
  feet 
  above 
  

   sea-level. 
  The 
  channel, 
  while 
  small, 
  is 
  very 
  pronounced 
  and 
  charac- 
  

   teristic, 
  and 
  has 
  been 
  fully 
  and 
  accurately 
  described 
  by

   as 
  follows 
  : 
  " 
  The 
  old 
  stream 
  channel, 
  which 
  once 
  carried 
  the 
  over- 
  

   flow 
  of 
  the 
  glacial 
  waters 
  from 
  the 
  lake 
  north 
  of 
  the 
  divide, 
  is, 
  

   however, 
  upon 
  the 
  extreme 
  eastern 
  side 
  of 
  the 
  valley, 
  upon 
  the 
  farm 
  

   of 
  Mr 
  A. 
  Signor. 
  The 
  head 
  of 
  the 
  outlet 
  is 
  at 
  the 
  north 
  border 
  of 
  

   the 
  only 
  primitive 
  pine 
  forest 
  in 
  the 
  Cayuga 
  basin, 
  at 
  which 
  point 
  

   the 
  morainic 
  hills 
  fall 
  ofl 
  steeply 
  to 
  the 
  deep 
  valley 
  northward. 
  

   The 
  channel 
  runs 
  southeast 
  through 
  the 
  pine 
  forest 
  about 
  80 
  rods, 
  

   then 
  some 
  40 
  rods 
  through 
  cleared 
  fields, 
  and 
  then 
  bends 
  abruptly 
  

   to 
  the 
  east, 
  and 
  in 
  20 
  rods 
  reaches 
  the 
  Cattatonk 
  creek, 
  which 
  enters 
  

   the 
  valley 
  from 
  the 
  north 
  and 
  at 
  this 
  point 
  .flows 
  in 
  a 
  rock 
  bed 
  at 
  

   the 
  very 
  base 
  of 
  the 
  eastern 
  rock-wall 
  of 
  the 
  valley. 
  (Figures 
  

   4 
  and

  Just 
  before 
  reaching 
  Cattatonk 
  creek 
  the 
  channel 
  crosses 
  

   the 
  highway 
  close 
  to 
  the 
  house 
  of 
  Mr 
  S. 
  D. 
  Turk. 
  At 
  this 
  point 
  it 
  

   is 
  about 
  12 
  feet 
  lower 
  than 
  at 
  its 
  head 
  in 
  the 
  north 
  edge 
  of 
  the 
  

   forest.
