Wells in the southeast part of Tully are eighteen to twenty feet. At 
Van Wert natural springs occur along the south side of the ridge, This 
is the first exception known to the observed location of such springs in 
the “Spring Row,” as in other counties, which is on the north side of 
the ridge. There are some others at Van Wert on the north side also. 
On Mr. E. R. Wells’s farm, four miles west of Van Wert, is red soil, 
charged with protoxide of iron, and other evidences of extinct springs, 
on the north slope of the ridge. In all deep wells (7. ¢., those that pass 
through the blue clay) at Van Wert, the water rises nearly or quite to 
the surface, and considerable effort has been put forth to secure such 
constant flow at various places in the city, although the shallow wells 
are unfailing and easily obtained.

These artesian wells which rise from the water-bearing gravel below 
the Drift clay, together with others in different parts of the county, prove 
the Drift to be about 40 feet thick in Van Wert county. | 
The Van Wert ridge is sometimes double. Such an instance may be 
seen north from Streughn. The first one lies within half a mile of that 
village, but the principal ridge road is half a mile further north, located 
on the second ridge. Both rise abruptly from the adjoining flat land, 
having descent in both directions. They seem to be perfectly identical 
in form and composition, although the former can only be traced two or 
three miles toward the west, when, turning a little more to the south, it 
slowly sinks away and disappears in the general Drift. A similar gravel
