114 PLEISTOCENE OF INDIANA AND MICHIGAN. 



Delaware County. — At Muncie the thickness of drift in the several gas borings ranges from 

 nothing to 100 feet, though the altitude of the surface does not vary more than 25 feet. 



At Daleville wells penetrate 8 to 15 feet of yellow till and obtain water at slight depth in 

 sand and gravel. A gas well penetrated 12 to 15 feet of yellow till. The remainder of the 

 drift is sand and gravel. Rock was entered at 85 feet. 



Madison County. — At Markleville a gas boring penetrated 147 feet of gray till containing 

 thin beds of sand and gravel. A piece of wood was struck at about 140 feet. The altitude 

 of this well by gravel-road survey is 100 feet above Pendleton, or 945 feet above the sea. 



In Elwood gas well No. 1 penetrated 108 feet of drift, mainly blue till. Gas well No. 2, 

 near Duck Creek, at an altitude 10 or 12 feet lower than No. 1, penetrated 65 feet of drift, mainly 

 till, except for about 12 feet of sand at the bottom. Gas well No. 3, one-half mile east of the 

 village on ground as elevated as No. 1, penetrated only 40 feet of drift. 



Hamilton County. — At Clarksville, P. P. Whitesall has a gas well which penetrated 16 

 feet of drift, and his neighbor William Coverdale has another at a similar altitude that pene- 

 trated 82 feet of drift. At Mr. Sohl's, about a mile west of Clarksville, two wells penetrate 

 each only 6 feet of drift. 



Two miles east of Noblesville, at the "Granger wells," the drift is 80 feet thick, of which 

 the greater part is gravel. Near Noblesville nearly all the gas wells and water wells penetrate 

 much gravel, the only marked exception noted being a well west of White River in which till 

 constituted the bulk of the 98 feet of drift. Many of the wells, however, in which the greater 

 part of the drift is sand and gravel, contain a thin bed of surface till. The thickness of the 

 drift varies considerably, a well two blocks north of the courthouse in Noblesville having 136 

 feet, another one-half mile north in White River valley at an altitude about 30 feet lower 

 having only 33 feet, and a third 1J miles north of the courthouse on the upper gravel terrace 

 along the river passing through 176 feet. In this last well assorted material persisted to 40 

 feet or less of the bottom, at which depth a red ocherous clay overlying the limestone was 

 entered. 



At Cicero the following sections of drift in gas wells were reported by William Neal: 

 Well No. 1 has 161 feet of drift, of which the upper 15 feet is till and the remainder more sand 

 and gravel than till. Well No. 2, on ground 8 or 10 feet lower than No. 1, has 141 feet of drift, 

 which includes more till than No. 1 but has a large component of sand and gravel. Well No. 3, 

 a mile south of Cicero, at an altitude not perceptibly different from that of No. 1, has 270 feet 

 of drift, including a bed of till about 20 feet thick at the surface; below this for 175 feet the 

 drift is chiefly sand and gravel, with thin beds of clay; the lowest part (about 60 feet) is a red 

 clay, apparently like that at Noblesville, in which no pebbles were noticed. 



At Arcadia records of two gas wells show 146 and 130 feet of drift, nearly all till, mainly 

 blue. Thin beds of sand and gravel were passed through. 



At Atlanta, near the line of Hamilton and Tipton counties, a gas well penetrated 320 

 feet of drift, consisting of yellow and blue till to about 80 feet and of sand and gravel on to 

 the bottom. 



Tipton County. — In southeastern Tipton County at Mr. Hobbs's residence in sec. 36, T. 

 21 N., R. 5 E., a well struck rock at 73 feet. The following is the section of drift:

 In the level plain along the Lake Erie & Western Railroad east of Hobbs station there 

 is a small tract of surface gravel which is used for ballast on the road. In this gravel bed 

 many large angular blocks of limestone are embedded. Near Hobbs station are two gas wells. 

 One in sec. 1, T. 21 N., R. 5 E., penetrates the following beds of drift:
