east of door of Niagara street entrance to Niagara County court-house, at Lockport, stamped 
"616." The elevation of this bench mark, 615.183 feet above mean sea level, is based 
on the nearest State engineer's bench mark. This list was previously published in the 
Appendix to the Eighteenth Annual Report of the Director, United States Geological 
Survey. The elevations there listed have been corrected by the addition of about 1 foot. 
The leveling was done in 1896 under the direction of Mr. Frank Sutton, topographer, by 
Mi - . E. L. McNair, levelman. The standard bench marks are stamped without datum 
letters, but with figures of elevation mostly 1 foot too great.
