PRIMARY LEVELING. 73 
CAYUGA, CHEMUNG, ONONDAGA, TIOGA, AND TOMPKINS COUNTIES. 
AUBURN, DRYDEN, MORAVIA, OWEGO, SKANEATELES, AND WAVERLY QUADRANGLES. 
The elevations in the following list result from a readjustment of leveling reported upon 
in the Appendixes to the Eighteenth and Twentieth Annual Reports of the Director, 
United States Geological Survey, with additional work on Owego quadrangle. Leveling 
done by the Lehigh Valley Railroad was employed extensively in the readjustment. For 
additional elevations on Owego and Waverly quadrangles see "Precise leveling." 
The leveling on Auburn, Skaneateles, and Moravia quadrangles was done in 1896 under 
the direction of Mr. J. H. Jennings, topographer, mostly by Mr. A. B. Pomme, levelman; 
that on Waverly and Dry den and part of Owego quadrangles was done in 1898 under the 
direction of Mr. R. D. Cummin, topographer, by Mr. W. W. Gilbert, levelman, and the 
remainder on the Owego quadrangle was done in 1900 under the direction of Mr. Jennings 
by Mr. W. E. Green, levelman. The standard bench marks oh Waverly, Dryden, and 
Owego quadrangles are stamped "ALBANY" or "A" in addition to figures of elevation, 
mostly 1 foot too low. Those set in 1896 have no datum letter and the elevations stamped 
are mostly 2 feet too high on Auburn and Moravia quadrangles and 3 feet too high on 
Skaneateles quadrangle, but the corrected elevations given on the latter quadrangle are 
possibly 1 foot low, though the nearest of two connections which differed by that amount 
was taken.
