An account of an odd spring in Westphalia, together with an information touching salt-springs and the straining of salt-water

Abstract

An observing gentleman did lately write out of Germany, that in Westphalia in the diocess of Paderborn, is a spring, which looses it self twice in 24 houres; coming always, after 6 houres, back again with a great noise, and so forcibly, as to drive 3 mills not far from its source. The inhabitants call it the Bolderborn, as if you should say, the Boysterous spring.
