  at 
  Ridge 
  Mills. 
  The 
  

   gaging 
  station 
  at 
  Kidge 
  Mills 
  was 
  located 
  at 
  the 
  dam 
  of 
  the 
  Rome 
  

   Waterworks, 
  three 
  miles 
  above 
  Rome. 
  This 
  dam 
  is 
  of 
  rough 
  tim- 
  

   ber 
  with 
  plank 
  facing, 
  having 
  a 
  slightly 
  irregular 
  crest, 
  123 
  feet 
  

   in 
  length, 
  which 
  is 
  divided 
  into 
  several 
  sections 
  to 
  facilitate 
  dis- 
  

   charge 
  computations. 
  The 
  computations 
  have 
  been 
  made 
  from 
  

   data 
  as 
  per 
  Cornell 
  University 
  experiment 
  No. 
  6.
