The Artesian Well is located at 311 Bluff street, and is 

 2,011 feet deep. It was originally drilled by D. A. Magee 

 & Company. It is now owned by Christerman & Company, 

 who use the water in their mineral water plant. Two 

 analyses are given below. The one by Juan H. Wright. M. 

 I)., an analytical chemist of St. Louis, Missouri, was 

 made in May, 1883. The one by Prof. Thomas E. Pope of the 

 Iowa Agricultural College was made in 1884. The reports 

 of these two analyses have kindly been furnished by Mr. 

 D. A. Magee. It will be observed that there is a marked 

 difference between the two analyses. It may be said, 

 however, that Mr. Pope's analysis is in fair accord with 

 that made by J. B. Weems and reported as the "official 

 analysis" in Vol. VI, page 225, of the Report of the Iowa 

 Geological Survey. The results are given in U. S. grams 

 per gallon.
