LEHIGH, LEBANON, BERKS, AND LANCASTER COUNTIES. 
Wernersville and Slatington Quadrangles. 
The following elevations are based on an aluminum tablet placed in 
front face of State librae at Harrisburg, Pa. The height of this is 
determined from mean sea level by precise levels of the United Slates 
Coast and Geodetic Survey, the Pennsylvania Railroad, and the 
United States Geological Survey, the connection having been made 
by the latter organization. The elevation of this datum is accepted 
as 363. 9G1 feet above mean sea level. The immediate elevations on 
which the leveling reported upon herewith is based are bencli marks 
of the United States Coast and Geodetic Survey transcontinental line 
as published in their Latest adjustment, Reporl of L898-99, Appendix 8. 
The leveling was done under the direction of Mr. Horsey Munroe, 
topographer, by Messrs. B. E. White and Margraves Wood, Levelmen. 
All bench marks dependent upon this datum are marked with the 
letters "HARRISBURG" in addition to the figures of elevation.
