  Port 
  Stanley 
  with 
  Dundas, 
  Devonic 
  limestones 
  occur 
  at 
  a 
  consider- 
  

   able 
  elevation 
  above 
  Lake 
  Erie 
  (Spencer). 
  Hence 
  the 
  southwest- 
  

   ward 
  continuation 
  of 
  the 
  Dundas 
  channel 
  must 
  be 
  placed 
  between 
  

  

  ^These 
  maps 
  are 
  intended 
  merely 
  to 
  illustrate 
  the 
  kind 
  of 
  drainage, 
  which 
  it 
  

   is 
  believed 
  existed 
  in 
  preglacial 
  times 
  in 
  the 
  Laurentian 
  region. 
  The 
  ancient 
  

   consequent 
  streams 
  are 
  probably 
  correctly 
  located; 
  yet 
  it 
  must 
  be 
  stated 
  

   that 
  the 
  region 
  between 
  Hamilton 
  and 
  Port 
  Stanley 
  has 
  not 
  been 
  sufficiently 
  

   explored 
  to 
  make 
  the 
  course 
  indicated 
  certain. 
  These 
  consequents 
  may 
  have 
  

   had 
  a 
  more 
  indirect 
  course, 
  for 
  if 
  the 
  country 
  was 
  worn 
  down 
  to 
  peneplain 
  

   condition, 
  as 
  appears 
  to 
  have 
  been 
  the 
  case, 
  these 
  streams 
  may 
  have 
  learned
