  Genesee 
  river. 
  This 
  river 
  issues 
  from 
  the 
  highlands 
  of 
  the 
  Alle- 
  

   gheny 
  plateau 
  in 
  Potter 
  county, 
  Pennsylvania, 
  a 
  few 
  miles 
  south 
  

   of 
  the 
  New 
  York 
  State 
  boundary. 
  Entering 
  Allegany 
  county, 
  it 
  

   first 
  runs 
  northwesterly 
  for 
  upward 
  of 
  30 
  miles 
  to 
  near 
  the 
  village 
  

   of 
  Caneadea, 
  at 
  which 
  point 
  it 
  turns 
  northeasterly, 
  this 
  direction 
  

   being 
  generally 
  maintained 
  to 
  the 
  mouth. 
  It 
  flows 
  entirely 
  across 
  

   the 
  county 
  of 
  Allegany 
  and 
  then 
  for 
  several 
  miles 
  forms 
  the 
  

   boundary 
  between 
  Livingston 
  and 
  Wyoming 
  counties, 
  after 
  which 
  

   it 
  crosses 
  the 
  northeast 
  part 
  of 
  Livingston 
  into 
  Monroe 
  county, 
  

   through 
  which 
  it 
  continues 
  to 
  its 
  mouth 
  at 
  Charlotte. 
  Above 
  

   Portage 
  its 
  course 
  from 
  the 
  State 
  line 
  is 
  chiefly 
  through 
  an 
  alluvial 
  

   valley. 
  

  

  From 
  Portage 
  to 
  Mount 
  Morris 
  the 
  river 
  flows 
  through 
  a 
  deep 
  

   and 
  in 
  some 
  places 
  narrow 
  canyon 
  for 
  a 
  distance 
  of 
  over 
  20 
  miles. 
  

   The 
  Portage 
  falls, 
  with 
  a 
  total 
  descent 
  including 
  the 
  intervening 
  

   rapids 
  of 
  about 
  330 
  feet, 
  are 
  at 
  the 
  head 
  of 
  this 
  canyon. 
  The 
  

   Upper 
  Portage 
  falls 
  have 
  a 
  descent, 
  including 
  the 
  rapids, 
  of 
  about 
  

   70 
  feet. 
  Half 
  a 
  mile 
  below 
  are 
  the 
  Middle 
  falls, 
  with 
  a 
  descent 
  of 
  

   110 
  feet; 
  while 
  2 
  miles 
  below 
  begin 
  the 
  Lower 
  falls, 
  consisting 
  

   of 
  a 
  series 
  of 
  rapids 
  about 
  half 
  a 
  mile 
  long 
  with 
  an 
  aggregate 
  

   fall 
  of 
  150 
  feet. 
  These 
  three 
  falls 
  may 
  be 
  taken 
  as 
  aggregating 
  

   about 
  270 
  feet, 
  exclusive 
  of 
  the 
  rapids. 
  At 
  present 
  no 
  power 
  

   developments 
  exist. 
  Formerly 
  a 
  sawmill 
  was 
  located 
  at 
  the 
  Mid- 
  

   dle 
  falls, 
  but 
  on 
  account 
  of 
  the 
  extinction 
  of 
  the 
  lumber 
  business 
  

   on 
  the 
  stream 
  it 
  has 
  not 
  been 
  operated 
  for 
  many 
  years. 
  

  

  At 
  Mount 
  Morris, 
  Genesee 
  river 
  issues 
  into 
  a 
  broad, 
  level, 
  allu- 
  

   vial 
  valley 
  from 
  1 
  to 
  2 
  miles 
  wide, 
  which 
  continues 
  to 
  near 
  Roch- 
  

   ester, 
  where 
  there 
  is 
  a 
  descent 
  of 
  262 
  feet 
  in 
  about 
  3 
  miles. 
  The 
  

   Upper 
  falls 
  at 
  Rochester, 
  90 
  feet 
  in 
  hight, 
  are 
  a 
  cataract 
  in 
  the 
  

   Niagara 
  limestone, 
  while 
  at 
  the 
  Lower 
  falls, 
  94 
  feet 
  in 
  hight, 
  the 
  

   Medina 
  sandstone 
  appears. 
  The 
  foregoing 
  figures 
  do 
  not 
  include 
  

   the 
  dams 
  above 
  the 
  falls. 
  

  

  The 
  principal 
  tributaries 
  of 
  the 
  Genesee 
  river 
  are 
  Canaseraga, 
  

   Honeoye 
  and 
  Conesus 
  creeks 
  from 
  the 
  east, 
  and 
  Oatka, 
  Black 
  and 
  

   Wiscoy 
  creeks 
  from 
  the 
  west. 
  Honeoye, 
  Canadice 
  and 
  Hemlock 
  

   lakes 
  are 
  tributary 
  to 
  the 
  Honeoye 
  creek, 
  and 
  Conesus 
  lake 
  to
