466 THE GEOLOGY OF MINNESOTA 



[Well,, 



pan, which almost invariably is overlain by a considerable thickness of the last, 10 feet. Small 

 pieces of lignite, derived from Cretaceous strata mingled with the drift, are frequently found; but 

 no shells, and no interglacial peat nor wood. 



Brush Creek. Guslav Buscho; sec. 8; well, 20; soil, 2; yellow till, 4; quicksand, 1 foot; blue 

 till, moist and sticky, yet harder than the upper till, 13 feet; water rose five feet from a vein of 

 sand at the bottom. 



Walnut Lake. C. F. Zimmerman; 8. E. J of sec. 4; well, 32 feet; soil, 2; yellow till, 15; harder 

 blue till, 15; water rose in a half day twenty-five feet from sand at the bottom. 



O. A. Odell, sec. 8: well, about 50 feet deep; all stratified gravel and sand. 



C. S. Bates; S. W. ^ of sec. 15: well, 30 feet; soil, 2; a marly layer, 1 foot; fine gravel, con- 

 taining pebbles up to two or three inches in diameter, and sand, 27; water abundant, fifteen feet 

 deep. The two last are upon the high rolling tract of modified drift, apparently of kame-like 

 origin, which forms part of the moraine. Mr. Morse has bored to a depth of 166 feet in this 

 township, about two miles north of Walnut lake, not reaching the bottom of the glacial drift. 



Minnesota Lake. Chauncy Barber's well, near the depot, going through the drift into the 

 bed-rocks, has been before described. 



Lura. Also see a preceding page for Terhurne & Scheid's well, at Easton, in sec. 36. John 

 E. James; Easton: well, 70; soil, 2; yellow till, 15; softer blue till, 53; water rose forty-five feet 

 from sand at the bottom. Watson Cole, in the 8. E. j- of sec. 32, has bored 160 feet, but the strata 

 passed through were not learned. 



Mr. Ilaight reports that in boring a well in this township, about two miles north of Easton, 

 he met, at 60 feet below the surface, a layer of mixed sand and grass-leaves, appearing like drifted 

 grass on a sandy beach. This was between beds of till, and marks an interglacial epoch; but no 

 other testimony of this kind was obtained in Faribault county. 



Barber. Andrew Wesner; sec. 22 : well, 20 ; soil, 2 ; gray till, 5 ; blue till, 5; yellowish 

 gravel and sand, 8 feet, with water in its lower portion. 



Emerald. Fred Weber; sec. 10: well, 24 feet; soil, 2; yellow till, 4; blue till, soft and 

 sticky, 18; no gravel por sand layers; water seeps from the upper till, and is very scanty in a dry 

 season. 



F. Dreblow; Ewald post-office, sec. 30: well, 22; soil, 2; gray till, 2; blue till, 18; seep water 

 only. 



Elmore. Caleb McCarther; in southeast part of this township: well, 81 feet; soil, 2; yellow 

 till, 18; harder blue till, 60; coarse gravel, 1 foot; from which water rose eighty feet, stopping at 

 one foot below the surface. 



Blue Earth City. George McCarther; in the city: well, 92 feet, being the deepest within the 

 corporation; soil, 2; yellow till, 18; harder, dark till, 50; stratified gravel, sand and clay, 22; water 

 rises, attaining a depth of fifty feet. 



TheTailroad well here is 68 feet deep, finding soil and yellow till, 20 feet; blue till, 48 feet; 

 with water rising from the bottom thirty-five feet. The elevator, close north of the last, has a 

 well 36 feet deep, containing twenty feet of water. 



Joseph Schimek, S. E. }, sec. 20; well, 44 feet; soil, 2; yellow and blue till, 42; only seep 

 water. In another well, a quarter of a mile farther east, water rose forty feet from the bottom. 

 G. B. Franklin, well-maker, states that the yellow till in this township is commonly 10 to 20 feet 

 thick, its lowest foot being very hard, cemented by iron-rust. This is succeeded below by 15 to 

 20 feet of soft, bluish till, which in turn is underlain by a darker, harder, and more stony till, 

 called " hardpan." 



Delavan. H. E. Mayhew; at the village and depot, in sec. 36; well, 60 feet deep; yellow till, 

 15; soft blue till, 45; water rises from sand at the bottom to twenty feet below the surface. 



Winnebago City. W. II. Holley; in the city: well, 96 feet; soil, 2; yellow till, 15; soft, blue 

 till, 74; dark hardpan, with many limestone pebbles, 5 feet; water rose fifty feet from sand and, 

 gravel at the bottom. The ten bushels of this sand and gravel which were drawn up contained 

 about a peck of lignite in small fragments. Mr. W. Z. Haight supplied the record of this well; as 

 also of the deep well at the Winnebago City mills, which reaches into the bed-rock, as before 

 described. He states that in the vicinity of this city the order of the drift deposits is generally as 

 follows: yellow till, about twenty feet; soft, blue till, 30 to 50 feet, becoming near its base a lighter
