TRIANGULATION STATIONS. 
Positions in eastern Ohio published herewith result from the field 
work of Messrs. W. T. Griswold in 1900, A. H. Thompson in 1901, and 
G. T. Hawkins and S. S. Gannett in 1902. 
Previous to the latter date positions depended upon Maryland 
Heights and Sugar Loaf stations of the United States Coast and Geo- 
detic Survey, near Harpers Ferry, W. Va., but during the season of 
1902 Mr. Gannett extended a belt of triangulation from Wray-Gebhardt 
stations in the transcontinental belt of United States Coast and 
Geodetic Survey near Huntington, W. Va., up the Ohio River and 
connected with previous work near Parkersburg, W. Va. 
The discrepancy in latitude and longitude was distributed arbitra- 
rily so as not to disturb figure adjustments, and has been applied so 
as to reduce all positions to the U. S. standard datum as derived from 
Wray-Gebhardt.
