CENTRAL SECTION OF TOPOGRAPHY. 
OHIO. 
PRIMARY TRAVERSE. 
Thirty 15-minute quadrangles, covering portions of 18 counties in 
the northwestern portion of the State, were controlled by 160 miles 
of primary traverse along railways by Mr. George T. Hawkins, topog- 
rapher, supplemented by 700 miles of traverse run by Mr. J. R. 
Ellis along highways, following meridians and parallels as closely as 
practicable. 
The following geographic positions were determined from primary 
traverse in 1901 by Mr. George T. Hawkins, topographer. 
The line starts from a point in the western part of the city of Toledo 
and follows the Lake Shore Railway to Edgerton, thence southwest 
via highways to the Indiana- Ohio State line, thence south along the 
State line to the Findlay, Fori Wayne and Western Railway, thence 
along that railway to Findlay, where it was connected with a line run 
in 1900.
