FRANKLIN COUNTY. 
Carlisle Quadrangle. 
The elevations published in the following list are based directty 
upon a "bench mark of the United States Coast and Geodetic Survey 
at Carlisle, Pa. This is marked by the letter "M" cut on the base of 
the column at the west side of the jail entrance. (See p. 560, Appendix 
No. 8, on hypsometry, of their report for 1898-99, published in 1900.) 
The elevation of this bench mark is accepted as 473.234 feet above 
mean sea level. 
The datum to which this leveling is referred is an aluminum tablet 
of the United States Geological Survey placed in the State library at 
Harrisburg, marked "364 HARRISBURG, 1899," the elevation of 
which is accepted as 363.961 feet above mean sea level, as corrected 
by the United States Coast and Geodetic Survey in 1 900. This eleva- 
tion is 0.148 feet higher than the elevation accepted for this bench 
mark in the Appendix to the Twenty-first Annual Report of the 
Director of this Survey, page 431. 
The leveling was executed under the general direction of Mr. 
Robert D. Cummin, topographer, by Mr. F. M. Taylor, levelman. 
The bench marks being referred to Harrisburg as datum are stamped 
with the letters "HARRISBURG" in addition to their figures of 
elevation.
