WASHINGTON, WESTMORELAND, GREENE, AND FAYETTE COUNTIES. 
Brownsville, Connellsville, Waynesburg, Masontown, Uniontown, and 
morgantown quadrangles. 
The elevations published in the following list are based on and 
adjusted between bench marks established in the course of precise 
leveling by this Bureau at Point Marion, Uniontown, Wes1 Browns- 
ville Junction, and Baird flag station, Pennsylvania. The elevations 
of these are accei.)ted as correetcd by the latest adjustment of the 
United States Coast and Geodetic Survey. (See Report for 1898-99 
of that Bureau, Appendix No. 8.) 
Elevations published in the Twenty-firsl Annual Report of this 
Bureau, on pages 440-44-'!, are corrected as follows: To those listed 
in circuit from Uniontown via Faimington and Lanioni to Uniontown, 
add 0.181 foot; to those between Point Marion and Greensboro, add 
0.166 foot; in list Brownsville to Jacobs Ferry, add 0.192 foot to the 
elevation there given for the tablet at West Brownsville Junction, but 
the elevation at Jacobs Ferry is corrected by leveling of the United 
States Engineer Corps from West Brownsville Junction, raisins: it 
0.445 foot, and intermediate elevations are discarded. 
The leveling was executed under the direction of Mr. Frank Sutton, 
topographer, and by Messrs. William Crennell and J. H. Wetzel, 
levelmen, in 1899, and by the latter alone in 1900. 
All bench marks are referred to an aluminum tablet in the founda- 
tion of the Seventh Avenue Hotel at Pittsburg, marked "738 PITTS- 
BURG 1899," the elevation of which is accepted as 738.718 feet 
above mean sea level, and are stamped with the letters "PITTS- 
BURG " in addition to their figures of elevation.
