574 THE GLACIAL LAKE AGASSIZ. 



Larimore. — The well at tlie Sbermaii House, 60 feet deep in tbe fine silt and sand 

 of tlie Elk Valley delta, and other shallower wells, are noted on jjages SSA, 335. The 

 water is copious and of good quality, forming little scale on engine boilers. 



Manvel. — Joseph Colosky, Manvel Hotel: Artesian well, 166 feet deep, in alluvial 

 and lacustrine silt and till, inclosing occasional layers of sand and fine gravel. A 

 large flow of saline water was found in such a layer at 107 feet. The second flow, at 

 106 feet, is very strong, running from the 2-inch pipe at the rate of about iO gallons 

 per minute. 



Minneapolis and Northern Elevator Company : Artesian well, 175 feet; the water 

 is capable of rising more than 45 feet above the surface, there flowing from an inch 

 pipe (reduced from the diameter of the well, which is 2 inches) at the rate of about 

 6 gallons per minute. In 1887 this well had been running five years and showed no 

 diminution of flow. The water contains much sulphate of magnesia, not being so salt 

 as that at 107 feet. In engine boilers it forms a powdery precipitate, which is easily 

 blown out by the engineer, not being so troublesome as the usual scale. 



Turtle River. — Richard Forrest, northeast qixarter of section 28: A boring, seen 

 when it was in progress at 150 feet, had brackish artesian water flowing feebly from 

 sand all the way below 100 feet. 



Johnstown. — William Stratton, section 22 : Well in alluvial clay, which at the depth 

 of 19 feet contained a log 10 inches in diameter, thought to be birch. It was chopped 

 off' to permit the well to go deeper. Another well in the southwest part of this town- 

 ship found two similar tree trunks 16 feet below the surface. 



WALSH COUNTY. 



Ardoch. — Minneapolis and Northern Elevator Company : Artesian well, 164 feet, 

 the section being mostly till; large flow of saline water. 



Brooks Bros.' elevator: Well, 42 feet deep, 8 feet in diameter, with plenty of 

 water. A boring below this to the total depth of 100 feet from the surface was stopped 

 by a bowlder. The section was alluvial clay, 15 feet; sand and gravel, J foot; and 

 till, easy to dig and bore, 85 feet. Alkaline water seeps, much coming from the gravel 

 at 15 feet. 



Common wells ot Ardoch are 15 to 20 feet deep, most of them obtaining tolerably 

 good water. The town has two public wells or cisterns, each 13 feet deep and 13 feet 

 in diameter, and another measui'ing 15 feet in these dimensions, for fire protection. 



jl7i»to.— Minneapolis and Northern Elevator Company: Artesian well, 200 feet 

 deep; alluvial, lacustrine, and drift deposits, 190 feet, the lower two-thirds being till, 

 with no important water-bearing veins or layers ; then sand and gravel, 10 feet and 

 extending below. The water rushed up with such force as to bring pebbles an inch 

 in diameter, and rises when confined in pipes to a height of 60 feet above the surface.
