  lake. 
  Alluvium 
  completely 
  fills 
  the 
  vallej 
  between 
  the 
  East 
  and 
  

   West 
  hills 
  for 
  a 
  distance 
  of 
  two 
  and 
  a 
  half 
  miles, 
  and 
  rises 
  with 
  an 
  

   alnaost 
  imperceptible 
  slope 
  from 
  the 
  lake 
  to 
  its 
  southern 
  end. 
  It 
  is 
  

   a 
  large 
  delta 
  deposit 
  which 
  has 
  filled 
  in 
  the 
  end 
  of 
  the 
  lake, 
  and 
  is 
  

   somewhat 
  elevated 
  along 
  the 
  sides 
  by 
  material 
  washed 
  down 
  from 
  the 
  

   hills. 
  Proof 
  of 
  this 
  is 
  seen 
  in 
  several 
  places. 
  From 
  the 
  southwest 
  

   corner 
  of 
  the 
  lake 
  the 
  rock 
  cliff 
  continues 
  inland, 
  maintaining 
  its 
  

   abrupt 
  features 
  as 
  an 
  escarpment 
  for 
  a 
  quarter 
  of 
  a 
  mile, 
  and 
  gradu- 
  

   ally 
  rounding 
  off 
  as 
  it 
  has 
  weathered 
  away, 
  or 
  has 
  been 
  cut 
  down 
  

   artificially. 
  Along 
  the 
  base 
  of 
  the 
  cliff 
  are 
  found 
  the 
  typical 
  shore 
  

   line 
  pebbles 
  at 
  almost 
  any 
  point, 
  especially 
  if 
  searched 
  for 
  beneath 
  

   the 
  soil. 
  Moreover 
  the 
  fiat 
  has 
  the 
  typical 
  stratification 
  of 
  the 
  delta, 
  

   but 
  lake 
  ward 
  there 
  is 
  but 
  little 
  unconformity 
  because 
  of 
  the 
  slow- 
  

   ness 
  of 
  the 
  building 
  process, 
  as 
  nothing 
  but 
  the 
  finest 
  silt 
  can 
  reach 
  

   the 
  lake 
  through 
  the 
  sluggish 
  inlet. 
  This 
  also 
  accounts 
  for 
  the 
  

   slight 
  rise 
  away 
  from 
  the 
  lake, 
  all 
  the 
  coarser 
  material 
  having 
  been 
  

   deposited 
  immediately 
  upon 
  reaching 
  the 
  flats. 
  

  

  Fall 
  creek 
  leaves 
  its 
  gorge 
  and 
  enters 
  this 
  delta, 
  the 
  material 
  of 
  

   its 
  banks 
  becoming 
  finer 
  and 
  the 
  current 
  becoming 
  slower 
  as 
  it 
  

   approaches 
  the 
  lake, 
  half 
  a 
  mile 
  distant, 
  till 
  at 
  the 
  mouth 
  nothing 
  but 
  

   •the 
  finest 
  silt 
  can 
  be 
  carried 
  along 
  by 
  the 
  feeble 
  current. 
  

  

  On 
  the 
  beach, 
  in 
  the 
  middle 
  of 
  the 
  delta, 
  is 
  a 
  deposit 
  of 
  pebbles, 
  

   the 
  origin 
  of 
  which 
  is 
  interesting. 
  They 
  could 
  not 
  have 
  been 
  car- 
  

   ried 
  down 
  through 
  either 
  of 
  the 
  two 
  streams 
  across 
  the 
  fiat. 
  It 
  is 
  

   hardly 
  possible 
  that 
  they 
  were 
  brought 
  from 
  the 
  east 
  side 
  of 
  the 
  lake 
  

   by 
  littoral 
  currents 
  and 
  wave 
  action 
  set 
  up 
  by 
  the 
  prevailing 
  north 
  

   winds, 
  as, 
  for 
  a 
  long 
  distance 
  in 
  the 
  corner 
  of 
  the 
  lake 
  the 
  water 
  is 
  

   extremely 
  shallow, 
  and 
  no 
  such 
  pebbles 
  exist 
  there. 
  The 
  water, 
  

   opposite 
  the 
  deposit, 
  is 
  less 
  than 
  two 
  feet 
  deep 
  for 
  several 
  hundred 
  

   feet 
  out, 
  and 
  similar 
  pebbles 
  are 
  scattered 
  over 
  the 
  sandy 
  bottom 
  ; 
  

   so 
  it 
  is 
  probably 
  that 
  the 
  shore 
  ice 
  and 
  that 
  coming 
  down 
  the 
  creeks, 
  

   with 
  pebbles 
  frozen 
  in, 
  has 
  been 
  blown 
  aground 
  in 
  shallow 
  water, 
  

   where 
  it 
  has 
  melted 
  and 
  dropped 
  the 
  pebbles 
  and 
  the 
  latter 
  have 
  

   been 
  washed 
  ashore 
  during 
  storms. 
  

  

  Continuing 
  up 
  the 
  valley, 
  south 
  of 
  the 
  delta, 
  the 
  land 
  rises 
  gentl}'^ 
  

   with 
  a 
  rolling 
  aspect 
  to 
  the 
  top 
  of 
  the 
  terminal 
  moraine 
  at 
  Spencer 
  

   summit 
  — 
  a 
  distance 
  of 
  15 
  miles. 
  Beyond 
  the 
  beginning 
  of 
  the
