NOTES OF ARTESIAN AND COMMON WELLS. 573 



filled with Siiiul. The bottom of this boring is at uearly the same elevation above the 

 sea as that of the deep artesian wells of Blanchaid and Mayville, being, like them, 

 doubtless, iu the Dakota sandstone. 



GRAND FORKS COUNTY. 



Northwood.— Red Eiver Valley Elevator Company: Well, 20 feet deep, iu delta 

 sand; water usually 10 to 15 feet deep, overflowing in the spring. Common wells 

 here are 15 to 18 feet deep, supplying good water, which forms little scale on engine 

 boilers. 



Kempton.— Wells in the vicinity of Kempton are about 20 feet deep, the section 

 being soil, 2 feet; fine clayey sand, 10 feet; a harder bed of sand, 2 feet; and quick- 

 sand below, which contains an ample supply of excellent water. 



Grand Forks.— A railway well bored near the depot in 1881 to the depth of 265 

 feet, 5 inches in diameter, reduced below to 3i inches, yielded in August of that year, 

 probably after the lower part of the pipe had become filled with sand, only a very 

 scanty overflow; water saline, not used. 



C. J. Alloway, in the north edge of the city: Artesian well, 270 feet; alluvial 

 and lacustrine clay, 30 feet; till, inclosing occasional beds of sand and gravel, 220 feet: 

 and sand, 20 feet; the water, too saline to be used, rises 2 feet above the surface. 



The common wells of Grand Forks, 20 to 30 feet deep, have water of fair quality, 

 but the city is mainly supplied through waterworks which pump from the river. 



Brenna. —hawrence Kennedy, in the north part of this township, about halfway 

 between Grand Forks and Ojata, has a flowing well of brackish water 90 feet deep. 



O/rt/rt,— Minneapolis and Northern Elevator Company: Flowing well, 115 feet 

 deep; water saline, unfit for engine ()oilers, though it has been so used. Similar 

 artesian water was also found by this well at the depth of about 70 feet. Common 

 wells are mostly 15 to 18 feet deep, obtaining water that is slightly alkaline, though 

 not perceptibly so to the taste. When dug deeper they get bitter or salty water. 



^TOe»Y(f?o.— Wells in this village and its vicinity are 15 to 20 feet deep, in till, with 

 thin veins and layers of sand ; good water. One well, bored 70 feet deep, near the 

 depot, found no water supply, while another well 10 rods east found plenty of water 

 at 20 feet. 



The well of the railway tank was dug 53 feet deep in a dry season, and the work- 

 men at night left their tools at the bottom, which gave no sign of water; but the next 

 morning it was full of water to 8 feet below the surface. 



Arvilla.—Gomnwn wells at and near Arvilla are 15 to 30 feet deep, in till, obtain- 

 ing somewhat alkaline water. The first boring for a town well went nearly 200 feet 

 in the till, obtaining no sufficient water supply. A second boring found abundance 

 of good water at 85 feet, whence it rises to about 30 feet below the surface and is not 

 lowered by vigorous pumping.
