  Bay 
  Basin. 
  — 
  The 
  eastern 
  part 
  of 
  

   the 
  Algonquin 
  beach 
  has 
  been 
  greatly 
  deformed. 
  But 
  its 
  

   relation 
  to 
  the 
  St. 
  Clair 
  river 
  points 
  strongly 
  to 
  its 
  origin 
  as 
  a 
  

   lake 
  beach. 
  It 
  has 
  an 
  eastward 
  rise 
  of 
  about 
  one 
  foot 
  per 
  

   mile 
  throughout. 
  The 
  northward 
  rise 
  is 
  less 
  at 
  the 
  south. 
  At 
  

   Grand 
  Bend, 
  which 
  is 
  about 
  40 
  miles 
  northeast 
  of 
  Sarnia, 
  the 
  

   beach 
  is 
  18 
  feet 
  above 
  the 
  lake. 
  The 
  place 
  of 
  the 
  beach 
  (sub- 
  

   merged 
  20 
  feet) 
  off 
  Sarnia 
  was 
  calculated 
  on 
  these 
  data. 
  It 
  

   probably 
  passes 
  under 
  the 
  lake 
  near 
  Cape 
  Ipperwash, 
  which 
  

   is 
  about 
  25 
  miles 
  northeast 
  of 
  Sarnia. 
  On
