The following list of deep wells in Fulton County, Ohio, was prepared 

 by Carl D. Greenleaf, of Wauseon, who collected the data from the well 

 owners and well drillers. The wells are principally in the southern half of 

 the county, there being but few made in the northern half The majority 

 of the wells pass through a large amount of blue till. In some cases a 

 water-bearing gravel is found at the base of the di-ift, but quite often it is 

 found necessary to sink the wells a few feet into the underlying rock.
