The results recorded in this Bulletin are in continuation of investigations described in Bulletin No. 41 of the South Dakota Station. When this work was commenced it was my intention to include the waters from a wider area, from the Black Hills and from the outcrops of the Dakota sandstone along the foot hills of the Rocky Mountains. Arrangements had been made at that time with the U. S. Geological Survey to furnish this department with authenticated· samples of waters from those outlying regions, for the purpose, if possible, of throwing some light upon the geological origin of the waters of the great artesian basin of the Dakotas. Owing, however, to the readjustment at that time of the work of the survey, Director Walcott had no men stationed at the points in question; so it became necessary to abandon that portion of the work for the time being. But arrangements are now in progress, by means of which it is to be hoped that the samples may be gathered and at no distant day the work may be carried to completion. The results here recorded will find their chief. Value as follows: First, they will furnish a knowledge of the soluble constituents and the properties of the waters to those who are using or may wish to use them. Second they will tend to throw light upon the question of an eastern leakage from the great artesian basin, in which source these waters a.re often supposed to originate. The analyses given in this Bulletin are from authenticated samples. Superintendent I. D. Aldrich, of Grant County, formerly an Assistant in this Department, collected the samples from the Orant county basin and secured the valuable data recorded. Mr. W. H. Knox, my Assistant, visited the other basins, collected the samples and obtained the data. There are four known shallow artesian basins in South Dakota;
1st.-The Grant county basin.
2nd.-The Hurley basin.
3rd.-The Turkey Ridge Creek basin.
4th.-The Sanborn county basin, which also extends southward into Hanson and Miner counties and gradually merges in the west into the great artesian basin.
Each one of these basins presents some marked peculiarities, worthy of note. The purposes of this Bulletin may be best sub-served by a separate consideration of each basin.
