  Caved-in 
  roof 
  of 
  a 
  small 
  underground 
  stream 
  in 
  Lowville 
  limestone, 
  

   nearly 
  3 
  miles 
  west 
  of 
  Sanford 
  Corners, 
  Theresa 
  quadrangle, 
  looking 
  

   north. 
  A 
  good 
  position 
  for 
  the 
  camera 
  could 
  not 
  be 
  obtained 
  so 
  that 
  the 
  

   view 
  does 
  not 
  exhibit 
  the 
  conditions 
  clearly. 
  The 
  issuing 
  stream 
  shows 
  

   in 
  the 
  lower 
  left-hand 
  corner.
