JEFFERSON (Ol'NTY. 
LOUISVILLE CITY SURVEY. 
In the spring of 1906 J. R. Ellis, assistant topographer, was de- 
tailed to the commissioners of sewerage of the city of Louisville, for 
the purpose of extending lines of primary control throughout the city. 
The area of the city was divided into 12 rectangular blocks approxi- 
mately 1-5 by 2 miles, around the borders of which lines of primary 
traverse w r ere run. Particular care was taken to have the work done 
accurately, the deflection angles being measured four times, and dis- 
tances being measured twice with a steel tape under a constant ten- 
sion, the temperature also being noted. At intervals of 2,000 feet 
along the route of traverse a permanent station mark, consisting of a 
bronze tablet 3.5 inches in diameter, was countersunk and cemented 
into the top of a stone post 3 feet in length, dressed 6 inches square on 
top, set in the ground flush with surface. 
Positions are given on the United States standard datum and are 
based on North Base and Blind Asylum triangulation stations of the 
United States Coast and Geodetic Survey.
