The Artesian wells, now becoming so numerous in our State, are, I 

 believe, usually bored without any respect to the theory here advocated, 

 and so far as I have been informed, they are usually sunk far below the 

 level at which springs are known to break out. If, perchance, the drill 

 strikes a vein, the well may be used without going to so great a depth. 

 Last season, three Artesian wells were sunk in Mineral Point, within a 

 few rods of each other; and all, I believe, to twice the depth of never- 

 failing wells, within a short distance of them. 



In crossing the Koshkonong prairie, I saw three Artesian wells which 

 were said to be from seventy to one hundred and thirty feet deep ; and 

 at the deepest one I attempted to drink, but the water was so poor that 

 I preferred common brook water to it. And yet I found some good wells 

 of but few feet depth in the same neighborhood, proving that water 

 must run in veins in that prairie, and can be obtained at less expense 

 and trouble, and of a better quality, if proper means are used. 



The Artesian wells at Fond du Lac, I believe, are generally about one 

 hundred feet deep, and probably sixty or eighty feet below the surface 

 of Lake Winnebago. These wells, or most of them, being tubed, throw 

 out the water at the surface, but in streams of very different magnitude. 

 One which I saw, emitted a stream nearly as large as my arm, while 

 another could afford only enough to say that it run ; and I was informed 

 that in sinking some of these wells, others were caused to fail. There 

 must be veins of water under the plat of that thriving city, and at a 

 much higher level than those that supply their deep wells ; because 

 springs break out in the neighborhood, near the surface of that extended 

 and beautiful plain. But the country is so level that they have no 

 chance to show themselves, except in the river's bank, or some slight 

 ravine running into them ; and when these veins can be struck, wells 

 can be obtained at much less expense than by these Artesian concerns. 

 These wells must be supplied by veins fed by reservoirs as high, or 

 higher, than the surface of the town; but where, is a question which we 

 do not pretend to answer. 



In our lead mines, shafts have been sunk to different depths before 

 water has come in so as to disturb the miner. Some shafts are sunk 

 one hundred and twenty feet or more, without water ; while others are 

 flooded at thirty, forty or fifty feet depth. And in some instances, the 

 distances between shafts, with and without water, is very short, but a 

 few feet. Yet, some miners will have it that, at one common depth 

 below the surface, water will be found.
