A very good test occurred some years ago at the Hamilton mine, adjoining the great Chapin mine, in Wisconsin. It became almost impossible[69] to work the mine on account of the great influx6 of water.
Not much more than a half mile away was a lake that was charged with producing this annoying flow.
At the time of a temporary abandonment, the writer disputed this solution, and a survey was proposed to determine the level in the lake and mine, which showed the water in the mine eleven feet the lowest. To overcome this encroachment7 of water, an ingenious device was adopted by building a chimney over the point of inflow to the height of water level and stopping at the bottom; when completed allowed to fill.
When its true level was reached the rest of the mine was dry some distance above. It is doubtful if any place on the Earth will not respond with a flow of water within a mile in depth and rarely half that distance will need to be bored.
In the Mojave desert it is claimed a depth of 200 feet and often less gets a good flow of water. What sends it up and whence its source? In Michigan, Wisconsin, and many other adjacent States, a depth of 100 or 200 feet will produce large flowing wells. Where does this universal supply come from and why unchanged by wet or dry seasons? The flow from Lake Superior[70] is frequently larger in the dry season of August than in the wet season of spring.
If there is no unfailing supply of water in the Earth, where does the influence come from to produce an Oasis8 in a desert?
If artesian wells are bored in our arid and now almost worthless lands, wherever a fountain of water is tapped will be an Oasis around which the settler can produce fabulous9 wealth of crops and obtain forage10 for live stock. The expense of boring wells will be largely compensated11 by cheapness of land and bountiful results in vegetation.
