MICHIGAN. 
The mineral waters of Michigan are derived to a great extent from 
wells, which are nevertheless locally termed mineral springs. Many of 
these wells are artesian and were frequently sunk originally for other 
purposes than to find mineral waters. The artesian borings are espe- 
cially in the corniferous limestone and the Huron group (Devonian). 
Prof. Alexander Winchell says: " The conformation of the strata has re- 
tained all their original soluble constituents; hence all artesian waters 
in the State, save some outlying leached-out patches of the Parma sand- 
stone, will be found mineralized." The waters are classed as saline, 
carbonated, and sulphureted. The saline and sulphureted springs pre- 
dominate. The brines of Michigan (which are not included in our list) 
form an important factor in the industries of the State, nearly half of 
the salt product of the United States being credited to Michigan. The 
supply is derived mainly from artesian borings. So-called magnetic 
springs are prominent. Professor Winchell says their waters are not 
themselves magnetic, but that marked magnetic phenomena manifest 
themselves about the wells. 
The list, as given here, has been drawn principally from State geo- 
logical reports and from an essay on the magnetic and mineral springs 
of the State, by Dr. Stiles Kennedy.
