South from Cortland no wells have been sunk to the 
horizon of the salt beds, and hence the extent of the de- 
posits in that direction can not be given. , Farther west 
Barberton, Wadsworth and Rittman mark the southern line 
of exploration. The great difficulty of making tests lies in 
the depth of the formation sought after. The Ohio shales, 
which lie above the great limestones, thicken rapidly to the 
east and south, attaining nearly 2,400 feet along the Penn- 
sylvania line. 
At Sandusky a well, drilled for oil and gas. gave the
