  of 
  the 
  same 
  nature 
  as 
  that 
  previously 
  mentioned. 
  Scattered 
  

   all 
  through 
  the 
  clay 
  are 
  cobbles 
  of 
  limestone. 
  The 
  upper 
  strata 
  

   are 
  loamy 
  and 
  contorted, 
  while 
  underneath 
  in 
  the 
  yellow 
  clay, 
  which 
  

   is 
  very 
  tough, 
  the 
  stratification 
  is 
  almost 
  entirely 
  obliterated. 
  At 
  

   the 
  next 
  bank, 
  also 
  belonging 
  to 
  Lang, 
  there 
  is 
  6 
  feet 
  of 
  overlying 
  

   sand 
  and 
  gravel. 
  Scattered 
  through 
  the 
  clay 
  are 
  several 
  boulders 
  of 
  

   Calciferous 
  sandrock, 
  sandstone, 
  black 
  crystalline 
  limestone 
  and 
  

   gneiss. 
  The 
  overlying 
  material 
  is 
  mostly 
  unstratified 
  and 
  many 
  of 
  

   the 
  pebbles 
  are 
  8 
  inches 
  in 
  diameter. 
  At 
  the 
  bank 
  of 
  J. 
  T. 
  Moore 
  

   the 
  clay 
  is 
  very 
  tough, 
  and 
  the 
  stratification 
  is 
  obliterated 
  in 
  

   spots. 
  Several 
  ice-scratched 
  boulders 
  of 
  light 
  blue 
  limestone, 
  sand- 
  

   stone 
  and 
  Calciferous 
  sandro.ck 
  were 
  found 
  in 
  the 
  clay. 
  In 
  Moore 
  

   & 
  Lahey's 
  bank 
  the 
  clay 
  is 
  tough 
  and 
  compressed, 
  similar 
  to 
  the 
  

   other 
  yards. 
  It 
  likewise 
  contains 
  scratched 
  boulders, 
  specially 
  of 
  a 
  

   light 
  blue 
  crystalline 
  limestone. 
  Over 
  the 
  clay 
  is 
  2 
  to 
  4 
  feet 
  of 
  

   coarse 
  sand 
  and 
  gravel. 
  

  

  In 
  the 
  west 
  side 
  of 
  the 
  !N'ew 
  York, 
  Ontario 
  & 
  Western 
  railroad, 
  

   where 
  it 
  branches 
  off 
  from 
  the 
  "West 
  Shore 
  railroad, 
  a 
  cutting 
  in 
  the 
  

   hillside 
  shows 
  a 
  cross-bedded, 
  yellowish 
  sand 
  and 
  loamy 
  clay 
  with 
  

   patches 
  of 
  gravel 
  and 
  cobblestones 
  in 
  it. 
  Following 
  along 
  the 
  track 
  

   a 
  few 
  hundred 
  feet 
  we 
  come 
  to 
  the 
  clay 
  bank 
  of 
  C. 
  A. 
  and 
  A. 
  P. 
  

   Hedges. 
  This 
  shows 
  an 
  interesting 
  section 
  of 
  blue 
  clay 
  overlain 
  by 
  

   50 
  to 
  60 
  feet 
  of 
  cross-bedded 
  delta 
  deposits 
  of 
  sand 
  and 
  gravel. 
  

   The 
  clay 
  layers 
  are 
  obliterated 
  in 
  spots 
  and 
  in 
  others 
  much 
  con- 
  

   torted. 
  To 
  the 
  north 
  of 
  Hedges's 
  yard 
  in 
  the 
  railroad 
  cutting 
  the 
  

   clay 
  is 
  overlain 
  by 
  5 
  to 
  6 
  feet 
  of 
  sand 
  and 
  coarse 
  stones, 
  unstratified. 
  

   Following 
  up 
  the 
  track 
  on 
  the 
  left 
  side 
  just 
  beyond 
  the 
  crossing 
  

   of 
  the 
  road 
  from 
  Canterbury 
  to 
  ITew 
  Windsor 
  the 
  embankment 
  of 
  

   sand 
  and 
  coarse 
  gravel 
  is 
  cross-stratified, 
  being 
  a 
  portion 
  of 
  the 
  

   delta 
  of 
  Moodna 
  river. 
  The 
  character 
  of 
  this 
  embankment 
  changes 
  

   after 
  about 
  400 
  feet 
  to 
  unstratified 
  drift, 
  containing 
  boulders. 
  This 
  

   underlies 
  the 
  delta 
  material. 
  The 
  upper 
  terrace 
  at 
  Cornwall 
  is 
  un- 
  

   derlain 
  by 
  boulder 
  drift. 
  

  

  Its 
  structure 
  is 
  well 
  shown 
  along 
  the 
  track 
  at 
  Cornwall.
