  Mudge 
  — 
  Moicth 
  of 
  Grand 
  River. 
  

  

  The 
  descent 
  from 
  C 
  to 
  D 
  is 
  well 
  marked 
  but 
  not 
  steep. 
  

   The 
  surface 
  is 
  flat 
  and 
  several 
  feet 
  above 
  the 
  annual 
  overflow 
  

   of 
  the 
  Grand. 
  It 
  apparently 
  corresponds 
  in 
  height 
  with 
  the 
  

   sediment-fllled 
  area 
  at 
  A, 
  and 
  its 
  presence 
  appears 
  to 
  have 
  no 
  

   special 
  signiflcance. 
  The 
  two 
  terraces 
  described 
  form 
  the 
  site 
  

   of 
  the 
  village 
  of 
  Lyons. 
  

  

  A 
  third 
  terrace, 
  high 
  above 
  the 
  others, 
  is 
  found 
  across 
  Grand 
  

   River 
  to 
  the 
  west, 
  covering 
  a 
  considerable 
  area 
  at 
  E. 
  Its 
  limit 
  

   is 
  marked 
  by 
  a 
  line 
  of 
  low 
  hills, 
  beginning 
  near 
  the 
  big 
  bend 
  

   of 
  the 
  Grand 
  and 
  extending 
  across 
  northwest 
  to 
  the 
  main 
  

   valley. 
  It 
  is 
  this 
  terrace 
  that 
  helps 
  to 
  modify 
  the 
  bluff 
  feature 
  

   in 
  this 
  vicinity, 
  above 
  referred 
  to. 
  It 
  may 
  quite 
  likely 
  be 
  cor- 
  

   related 
  with 
  a 
  high 
  terrace 
  remnant 
  seen 
  at 
  Ionia 
  and 
  with 
  

   others 
  mentioned 
  by 
  Mr. 
  Taylor, 
  but 
  it 
  is, 
  I 
  think, 
  much 
  better 
  

   defined 
  and 
  more 
  extensive 
  than 
  any 
  of 
  its 
  probable 
  equiva- 
  

   lents 
  hitherto 
  observed. 
  Its 
  position 
  is 
  such 
  that 
  it 
  may 
  be 
  

   considered 
  tentatively 
  as 
  a 
  portion 
  of 
  the 
  Duplain 
  beach, 
  which 
  

   Mr. 
  Taylor 
  traced 
  as 
  far 
  as 
  Maple 
  Rapids. 
  

  

  The 
  evidence 
  from 
  this 
  little 
  embayment 
  is 
  on 
  the 
  whole 
  

   quite 
  in 
  harmony 
  with 
  that 
  from 
  other 
  sources, 
  in 
  its 
  bearing 
  

   upon 
  the 
  history 
  of 
  the 
  Pewamo 
  outlet.
