  filling 
  at 
  the 
  head 
  of 
  Seneca 
  Lake 
  

  

  and

  In 
  the 
  waning 
  of 
  the 
  Quebec 
  Glacier 
  and 
  the 
  recession 
  (north- 
  

   ward) 
  of 
  its 
  soutli 
  front, 
  it 
  served 
  as 
  a 
  barrier 
  in 
  all 
  of 
  the 
  north- 
  

   sloping- 
  valleys. 
  Glacial 
  lakes 
  were 
  thus 
  held 
  in 
  all 
  the 
  valleys, 
  and 
  

   the 
  present 
  laljes 
  are 
  lineal 
  descendants 
  of 
  the 
  ice-bound 
  lakes.
