MAIN MORAINIC SYSTEM OF THE SCIOTO LOBE. 409 



rock. The drift is gray clay with thin beds of sand. W. H. Wood's well, 

 near Locke, has a depth of 123 feet without reaching rock. This well is in 

 a slightly depressed portion of the uplands, and was made for the purpose 

 of obtaining a flow. Eleven water-bearing beds were passed through, but 

 water does not overflow from any of these beds. It stands, however, within 

 11 feet of the surface. An ocher-like bed was struck at the depth of 105 

 feet, whose material was so fine that it would not completely settle in water 

 ill forty-eight hours. 



At Hartford wells are only 20 to 40 feet deep, there being at these 

 depths an abundant water supply from sand beneath beds of till. 



In Utica, in the valley of Licking River, a well at Levi Kuowlton's 

 penetrated 58 feet of drift, inainly till, without reaching- rock. Two miles 

 north of Utica, at R. S TuUos's, a flowing well on comparatively low 

 ground terminates in drift at 85 feet. The drift is mainly till. On the 

 uplands east of Utica wells in the morainic area penetrate 25 to 40 feet or 

 more of drift. 



At Newark several borings for natural gas have been made, in some of 

 which a large amount of drift was penetrated, in one instance 235 feet, in 

 another 189 feet, and in another 147 feet. They are all in the Licking- 

 Valley, at about the same altitude as the Baltimore and Ohio station (819 

 feet). The drift is principally sand, but some clay appears in the surface 

 portions. In the northern part of the city, wells penetrate from 3 to 6 feet 

 of hard clay before entering the gravel. Exposures of till are numerous in 

 the south bluff of Licking River, in the eastern part of the city, up to a height 

 of about 60 feet above the stream. Bordering Newark on the northeast, as 

 above noted, is a lowland tract, standing about 100 feet above the Licking 

 River, which has considerable till in it. There is also sand, suitable for 

 molders' use, and gravel, the latter being sometimes disposed in arched 

 and distorted beds. 



West from Newark, on the main moraine, tlie drift has a thickness of 

 50 to 75 feet or more on the uplands and is probably much thicker in the 

 principal valleys. J. C. Wilcox's well, at his residence near Kirkersville, 

 on a very prominent part of the uplands, is 70 feet deep and does not 

 strike rock. Near Etna several wells ha^^e a depth of 50 feet without 

 reaching rock, and a boring made some years ago about a mile east of the 

 village was thought to have gone to a depth of 183 feet without reacliing 

 rock, the information being given from memory.
