  the 
  headwaters 
  of

  lie 
  in 
  the 
  horizon 
  

   of 
  the 
  granites 
  and 
  gneisses.

  This

   a 
  dam 
  which 
  is 
  the 
  property 
  of 
  the 
  New 
  York 
  Mills, 
  used 
  to 
  

   operate 
  an 
  extensive 
  cotton 
  mill. 
  The 
  dam 
  is 
  of 
  earth, 
  with 
  timber 
  

   facing,

  When 
  this 
  station 
  was 
  established 
  in 
  the 
  fall 
  of 
  1898 
  the 
  dam 
  

   was 
  watertight 
  and 
  leakage 
  consequently 
  neglected, 
  but 
  the 
  state- 
  

   ment 
  is 
  made 
  that 
  in 
  May, 
  1900, 
  the 
  leakage 
  was 
  found 
  to 
  be 
  5.6 
  

   cubic 
  feet 
  per 
  second 
  and 
  the 
  station 
  was 
  accordingly 
  abandoned 
  

   in 
  October, 
  1900. 
  The 
  flow 
  has 
  been 
  computed, 
  using 
  Bazin's 
  series 
  

   No. 
  175, 
  for 
  which 
  reference 
  is 
  made 
  to 
  the 
  paper 
  On 
  the 
  Flow 
  of 
  

   Water 
  Over 
  Dams. 
  

  

  Geologically 
  this 
  stream 
  lies 
  in 
  the 
  horizon 
  of 
  the 
  Hamilton 
  

   shales, 
  crossing 
  the 
  Helderberg 
  and 
  Salina 
  groups. 
  

  

  Discharge 
  measurements 
  of 
  Oriskany 
  creek. 
  This 
  station 
  is 
  

   located 
  at 
  the 
  canal 
  feeder 
  timber 
  dam 
  at 
  Oriskany, 
  with 
  a 
  crest 
  

   length 
  of 
  214' 
  feet. 
  The 
  profile 
  is 
  irregular 
  and 
  has 
  been 
  divided 
  

   into 
  three 
  sections 
  to 
  facilitate 
  computation. 
  The 
  dam 
  is 
  about 
  

   four 
  feet 
  in 
  hight. 
  A 
  section 
  is 
  shown 
  in 
  the 
  following 
  cut.
