MAIN MORAINIC SYSTEM OF THE SCIOTO LOBE. 41 1 



feet of the surface. Below this depth the drift is principally sand. At 

 Carroll a gas boring was reported by a citizen to have passed through 264 

 feet of drift. The altitude of the well mouth is 835 feet, making the rock 

 surface 561 feet above tide. The upper 15 feet is till, the remainder mainly 

 quicksand, though some gravel occurs. In a boring at Canal Winchester, 

 reported by the treasurer of the natural gas company, 216 feet of drift 

 was penetrated. The altitude of the well mouth is 769 feet, making the 

 rock floor 553 feet. The greater part of the drift is quicksand. This well 

 boring is one-half mile north of Little Walnut Creek. Along the creek 

 near Canal Winchester there are outcrops of shale, and 2 miles south of it, 

 at Lithopolis, rock rises to an altitude 200 feet or more above the level of 

 the mouth of the gas well, or nearly 1,000 feet above tide as indicated by 

 the East Columbus topographic sheet. 



At Lancaster several gas wells show a large amount of drift. The 

 following notes were obtained from Mr. Slocum, a citizen of Lancaster, 

 who kept careful records of the wells. The altitude of the majority of 

 the well mouths does not differ greatly from that of the railway station, 

 841 feet. 



Well No. 1, at the north side of the canal and west side of Maple 

 street, altitude about 825 feet, penetrated 131 feet of drift, entirely sand 

 and gravel; a log was struck at 26 to 27 feet. Well No. 2, just east of the 

 canal reservoir and about 50 feet above it (870 feet above tide), penetrated 

 60 feet of rlrift. Wells Nos. 3, 4, and 5 start on the sandstone which is at 

 the surface in the east part of the city. Well No. 6, on the Fair ground, 

 penetrated 180 feet of drift; a log was struck at about 100 feet; altitude 

 of well mouth about 850 feet. Well No. 7, at Forest Rose cemetery, pene- 

 trated but little drift. Well No. 8, in northwest part of the city, passed 

 through 180 feet of drift; altitude of Avell mouth about 840 feet. Well 

 No. 9, near center of city, south of King street, has 180 feet of drift; 

 altitude about 8 lO feet. Well No. 10, east of center of city and north of 

 Main street, has about 180 feet of drift; altitude about 840 feet. There 

 are several others not inade b}^ the city, each of whicli has 130 feet or 

 more of drift. 



As above noted (p. 269), there is in Lancaster a ch-ift ridge, upon which 

 the coui-t-house stands, containing much cemented gravel which has the 

 appearance of having suffered considerable erosion and leaching prior to
