  Waterville; 
  

   from 
  Deansville 
  to 
  Solsville, 
  and 
  from 
  Munnsville

   These 
  all 
  stretch 
  up 
  the 
  north 
  flowing 
  streams 
  to 
  about 
  the 
  

   position 
  of 
  the 
  divides 
  in 
  the 
  respective 
  valleys. 
  Extensive 
  

   valley 
  trains 
  appear 
  southward, 
  with 
  recurrent 
  terraces 
  and 
  

   kames 
  throughout 
  the 
  Chenango 
  valley.

  The 
  conditions 
  are 
  excellent 
  

   for 
  the 
  determination 
  of 
  linear 
  (southward) 
  and 
  vertical 
  dis- 
  

   tribution 
  of 
  bowlders, 
  from 
  the 
  manner 
  in 
  which 
  narrow 
  lines 
  

   of 
  outcrop 
  cross 
  the 
  track 
  of 
  the 
  ice. 
  It 
  is 
  evident 
  that 
  we 
  

   have 
  here 
  no 
  such 
  conditions 
  for 
  the 
  study 
  of 
  lateral 
  distribu-
