  a 
  dam 
  of 
  the 
  

   same 
  night 
  will 
  store 
  7,040,000,000 
  cubic 
  feet. 
  Since 
  no 
  con- 
  

   clusion 
  has 
  been 
  reached 
  as 
  to 
  which 
  of 
  these 
  sites 
  to 
  adopt, 
  for 
  

   the 
  purposes 
  of 
  comparison 
  a 
  mean 
  of 
  7,370,000,000 
  cubic 
  feet 
  has 
  

   been 
  taken 
  as 
  the 
  approximate 
  available 
  storage, 
  and 
  the 
  mean 
  

   of 
  |2,785,000 
  as 
  the 
  approximate 
  total 
  cost. 
  On 
  this 
  basis 
  the 
  

   estimated 
  cost 
  of 
  the 
  storage 
  becomes 
  |377.88 
  per 
  million 
  cubic 
  

   feet 
  of 
  water 
  stored. 
  These 
  figures 
  should 
  be 
  increased 
  by 
  25 
  per- 
  

   cent 
  in 
  order 
  to 
  conform 
  to 
  conditions 
  in 
  1904. 
  

  

  Portage 
  site. 
  Investigations 
  of 
  the 
  Genesee 
  river 
  storage 
  

   project 
  were 
  finally 
  completed 
  in 
  1896. 
  In 
  that 
  year 
  detailed 
  

   surveys 
  were 
  made 
  of 
  a 
  new 
  site 
  known 
  as 
  Portage 
  site, 
  the 
  pro- 
  

   posed 
  dam 
  to 
  be 
  located 
  at 
  Portageville, 
  about 
  1400 
  feet 
  above 
  

   the 
  Erie 
  railway 
  bridge, 
  at 
  a 
  point 
  where 
  the 
  gorge 
  presents 
  

   extremely 
  favorable 
  conditions 
  for 
  the 
  erection 
  of 
  a 
  high 
  dam. 
  

   At 
  this 
  place 
  solid 
  rock 
  exists 
  immediately 
  in 
  the 
  bed 
  of 
  the 
  

   river, 
  with 
  only 
  a 
  couple 
  of 
  feet 
  of 
  water 
  flowing 
  over 
  it, 
  and 
  also 
  

   extends 
  high 
  up 
  on 
  the 
  bluffs 
  at 
  either 
  side, 
  whereas 
  at 
  all 
  of 
  the 
  

   sites 
  in 
  the 
  gorge 
  near 
  Mount 
  Morris 
  the 
  rock 
  was 
  only 
  found 
  at 
  

   from 
  15 
  to 
  20 
  feet 
  below 
  the 
  water 
  surface 
  and 
  of 
  such 
  an 
  open 
  

   texture 
  as 
  to 
  require 
  cut-off 
  trenches 
  about 
  30 
  feet 
  deep, 
  or 
  to 
  a 
  

   total 
  depth 
  of 
  nearly 
  50 
  feet 
  below 
  the 
  water. 
  The 
  proposed 
  

   Portage 
  dam 
  is 
  also 
  500 
  feet 
  vertically 
  above 
  the 
  previously 
  men- 
  

   tioned 
  sites, 
  thus 
  rendering 
  that 
  additional 
  number 
  of 
  feet 
  avail- 
  

   able 
  for 
  power 
  purposes 
  —

  fact

  the

  side 
  of 
  the 
  Genesee 
  river 
  storage 
  

   project. 
  

  

  A 
  short 
  distance 
  above 
  the 
  proposed 
  Portage 
  site 
  the 
  upper 
  

   Genesee 
  valley 
  broadens 
  out 
  to 
  a 
  width 
  in 
  places 
  of 
  from 
  one 
  to 
  

   two 
  miles, 
  although 
  the 
  general 
  width 
  of 
  the 
  valley 
  does 
  not 
  ex- 
  

   ceed, 
  for 
  several 
  miles 
  in 
  extent 
  longitudinally, 
  about 
  one 
  mile. 
  

   It 
  narrows 
  in 
  two 
  or 
  three 
  places 
  to 
  a 
  less 
  width 
  than 
  this. 
  The 
  

   valley 
  is 
  now 
  a 
  good 
  agricultural 
  region, 
  in 
  a 
  fair 
  state 
  of 
  culti- 
  

   vation, 
  and 
  presents, 
  on 
  the 
  whole, 
  as 
  favorable 
  conditions 
  for 
  

   farming 
  as 
  any 
  similar 
  valley 
  in 
  the 
  State. 
  The 
  Pennsylvania 
  

   railway 
  passes 
  through 
  the 
  middle 
  of 
  the 
  valley 
  on 
  the 
  line 
  of 
  the 
  

   abandoned 
  Genesee 
  Valley 
  canal. 
  Along 
  the 
  line 
  of 
  this 
  railway 
  

   the 
  villages 
  of 
  Portageville, 
  Kossburg, 
  Wiscoy 
  and 
  Fillmore 
  are 
  

   situated. 
  The 
  reservoir 
  project 
  includes 
  the 
  relaying 
  of 
  the 
  rail-
