LE SUEUB COUNTY. 645 



Wells. Springs.] 



in its lower part. Such stratified clay is not common, the surface being usually till. Wells in 

 this region are generally only 10 to 30 feet deep, obtaining a good supply of water, which often 

 rises several feet. They seldom reach the blue till, which has a well-known reputation of being 

 harder than the yellow till of the surface. 



John Kuenkel; sec. 18 (on the Le Sueur prairie): well, 64 feet; soil, 2; sand, 15; sand and 

 gravel, coarsest below, 47; water at the bottom two feet deep, an abundant supply. 



Cleveland. Wells in this township are mostly 10 to 25 feet deep in till, with water rising 

 several feet from the bottom. 



F. S. Wilson ; Cleveland village : well, 18 feet; soil, 2 ; yellow till, 12 ; sand and gravel, 6 

 inches ; blue till, 4 feet. Water came slowly from the sand and gravel between the upper and 

 lower till, filling the well to two feet below its top in two days. 



Washington. John Kendall; sec. 6: well, 36 feet; soil, 2; yellow till, picked, 28; blue till, 

 much harder, 6; water seeps from the lowest eight feet of the yeHow till, filling the well ten feet 

 deep in the dry season. 



John Plant; S. W. 1 of sec. 9: well, 40 feet; soil, 2; yellow till, so hard that it must be picked, 

 33 ; harder blue till, 5 ; water seeps, coming mostly from a vein of sand seen on the southwest 

 side of the well at 30 feet, being scanty in a dry season. 



Le Sueur. Reinhardt Wagner; southwest corner of sec. 1 : well, 58 feet; sand and gravel, 

 56 feet; blue clay, 1 foot; greenish sand, 1 foot, with water rising from it three or four feet. 



Ottawa. The wells described in this township, like the last preceding, are within the area 

 of modified drift called the Le Sueur prairie. 



E. T. Jones; N. E. J of sec. 23: well, 110 feet; sand and gravel, 100, including a thin clayey 

 layer at about 75 feet; gray till, 10 feet and extending below. 



C. N. Pmney; southwest comer of sec. 24: well, 90 feet; consisting wholly of stratified drift, 

 being mostly sand and gravel, the coarsest beds containing pebbles up to six inches in diameter, 

 and also including occasional layers of clay, two to six inches in thickness. The lowest stratum 

 dug through was quicksand, with water, which lasted several years, afterward failing. This lies 

 on very hard bluish till. 



J. G. Miller; N. E. i of sec. 26, a quarter of a mile west from the last: well, 60 feet; sand 

 and gravel, 57 ; blue till, very hard, 3. Another well a hundred feet southwest from this, at 

 nearly the same hight, both being in a narrow valley fifteen feet or more below the general level 

 was 58 feet deep; being sand and gravel, 7; then blue brick-clay, 14 (no corresponding layer was 

 found in the other well); sand and gravel, 4; and yellowish till, 3 feet, much easier to dig than 

 the blue till at the bottom of the other well. 



II. F. Von Lehe; southeast corner of sec. 13: well, 55 feet; soil, 2; clayey loam, 5; sand, 30; 

 gravel, fine above, growing coarse below, holding pebbles up to six inches in diameter, 18 feet; 

 with an abundance of water at the bottom, three feet deep. 



Kasota. S. D. Payne; S. E. J of sec. 28, on the northern part of a terrace of modified drift 

 which reaches thence three miles south: well, 60 feet deep, all the way in fine gravel and sand, 

 finding no water. 



Springs. Wells often encounter, within a moderate depth, copious veins of water which 

 show that there is a subterranean as well as a superficial drainage. The former becomes tribu- 

 tary to the latter by the springs that occur frequently along ravines and water-courses, where 

 these have been excavated so deeply as to intercept the underground currents. In many cases 

 these waters are irony, and deposit a rusty sediment. The only spring noted as deserving special 

 mention in this county is one of very large size, which issues from the foot of the bluff of limestone 

 and sandstone in Ottawa, at a point about a quarter of a mile south of Mr. Schwartz' limekiln. 



MATERIAL RESOURCES. 



The resources of this county in its fertile soil and abundance of wood- 

 land have been noticed on page 636. Water-powers, valuable quarries of 

 building stone, manufactures of lime and bricks, and deposits of peat, re- 

 main to be described here.
