“BREATHING WELLS” IN NEBRASKA.

“BREATHING WELLS” IN NEBRASKA.

Nebraska’s “breathing wells” are driven wells, which, after descending through from fifty to 100 feet of subsoil, penetrate a layer of dense limestone about four inches thick, which rests upon the water hearing gravel. Whenever an area of low barometer passes across the country the breathing wells sigh and roar with a noise sometimes audible at a distance of several rods. They blow outwards for several days, and then the current is reversed, and the air is drawn in—the changes always following fluctuations of the barometer. One explanation offered is that the norous travel underneath the limestone layer contains air. whose pressure fluctuates in sympathy with that of the air above ground. But it is felt that a complete explanation remains to be made.
