The elevations in the following list are the result of the readjustment of primary levels 
previously reported in Appendixes to the Twentieth and Twenty-first Annual Reports of 
the Director, United States Geological Survey. The leveling was done as follows: On 
Rochester, Macedon, and Palmyra quadrangles and part of Clyde quadrangle under Mr. J. H. 
Wheat, topographer, in 1898, and the remainder on the Clyde quadrangle under Mr. J. H. 
Jennings, topographer, in 1899; on Rochester quadrangle, by Mr. C. H. Semper, level- 
man, and on the other quadrangles by Messrs. Semper and D. E. Baxter, levelmen. The 
leveling on Oswego, Weedsport, and Baldwinsville quadrangles was done in 1898 under 
Mr. E. B. Clark, topographer, by Mr. Baxter, and that on Fulton quadrangle was done 
also in 1898, under Mr. Clark, by Messrs. Semper and Baxter. The standard bench marks 
are stamped mostly "OSWEGO" in full or abbreviated, in addition to figures of elevation, 
which are mostly 1 foot low.
