Artesian Wells in North and South Dakota.

ence with Prof. G. E. Culver, of the University of South Dakota, 

 and with Prof. C. W. Hall, of the University of Minnesota. 

 These data, with those obtained by me at Devil's lake and James- 

 town, I have placed in tabular form for convenient comparison, 

 showing (i and 2) the distances of the localities north and west 

 from the mouth of the Big Sioux river at the southeast corner of 

 South Dakota; (3) depths of the wells; (4) their pressure at the 

 surface, wherever it has been obtainable, in pounds per square 

 inch ; ( 5 ) the corresponding height or head to which the water 

 would rise above the surface; (6) the altitude, with reference to 

 the sea level, of the source of the artesian water in the Dakota 

 sandstone; (7) the altitude of the surface; and (8) the height of 

 the computed head of water above the sea.

*The pressure reported at Ashton is 100 or 125 pounds less than would 

 be expected in proportion with other localities; and at Groton it is some- 

 what more. The discrepancy of the latter, however, is no greater than 

 may be due to superior permeability of the water-bearing stratum.
