558 THE GLACIAL LAKE AGASSIZ. 



lldlstad. — The Minneapolis and Northern Elevator Company has an artesian 

 well, which is reiiorted to be about 250 feet deep. The common wells are similar to 

 those of Anthony in their depths and quality of water. 



Lockhart. — This township and others adjoining it have many flowing wells, vary- 

 ing from 100 to 200 feet in depth. 



On William Fisher's farm, in section 5, three artesian wells are each about 130 

 feet deep. Their water, which rises 4 feet above the surface, is free from any alkaline 

 or saline taste. 



Leo Gnadt, section G : Artesian well, 105 feet deep, from which good water rises 

 3 feet above the surface. 



At the buildings of the Lockhart Farm, in section 29, a well 5 inches in diameter 

 was bored to the depth of 142 feet in the autumn of 1880, the section being as fol- 

 lows: Soil, 2 feet; yellow alluvial clay, or perhaps in part till, about 10 feet; blue till, 

 130 feet, to sand at the bottom, from which water of excellent quality rose to the 

 surface with a powerful flow. The water was allowed to run in its full amount during 

 a month or more, flooding a considerable tract for a mile northward. With the water 

 much sand was brought up and deposited by the stream in a neigbboring slough, its 

 estimated volume being approximately 300 cubic yards, spread on the average a foot 

 thick over a space about 100 feet in diameter. The flow of this well was reduced after 

 a time by a cap and gauge to a small stream ; but in the following December it ceased, 

 because the bottom of the pipe for about 20 feet had been compactly filled with sand. 



In July, 1881, a second well of similar diameter was bored a short distance south 

 of the preceding. Till extended to a depth of 141 feet, below which the boring went 

 into a bed of sand 16 feet, from which water rose to 15 feet above the surface, flow- 

 ing through an inch pipe about 60 barrels per day. Many fragments of lignite, up to 

 3 inches long, were found in several layers in the sand bed, probably a half bushel of 

 it in all being brought up as the boring progressed, but no lignite was encountered 

 in the till. One piece of wood 3 or 4 inches long, with numerous smaller fragments of 

 wood, was also found in the sand. 



Several other artesian wells similar to these have since been bored on this farm. 

 One of these, about 700 feet distant from the first well, struck water at 137 feet, which 

 rose with a much stronger and alarming flow, and soon found vent also alongside the 

 pipe, making a large hole and inundating the vicinity of the farm buildings and much 

 adjoining land. To carry away this water many laborers were quickly set to digging 

 ditches along a distance of several miles to the west. After some two weeks, how- 

 ever, the heavy flow mostly ceased, becoming principally confined to the pipe, with 

 only a moderate and controllable quantity coming to the surface outside the pipe. 



Shely. — Iver Nilson, in section 14, has a well 219 feet deep, with water at first 

 rising to the surface, but afterward to about 4 feet below the surface. This well 

 goes wholly through drift, nearly all till, but including occasional thin beds of gravel
