The elevations in the following list are the result of a line of precise leveling, based upo 
the Rochester datum connecting the Lake Survey gage bench mark at Charlotte with th 
State engineer's level line of 1901 at Rochester and continued south to a final eonnectio 
at Hornellsville with the precise-level line run by Mr. E. L. McNair, topographer, in 1898 
This line forms an element in the precise-level net and a factor in the 1903 adjust men 
of the same made by the United States Coast and Geodetic Survey. The amount of cor

the original elevation at Hornellsville by this line being lowered with respect to Charlotte 
The total divergence of the direct and reverse, simultaneous rodded lines is 0.096 foot. 
The double-simultaneous method was employed, with a Buff & Berger precise leve 
and a 4-second vial. The leveling was done during part of September, 1901, and part o
