    Valley called the Furlenthal, traversed by a stream, the Furlenbach, which joins the Ergolz just bekw Lausen, the Stockhalder occuppng the fork of the valleys. The Furlenthal contained six farm-houses, which were supplied with drinking-water, not from the Furlenbach, but by a spring rising on the oppo- site side of the valley to the Stockhalder. Now, there was reason to believe that, under cer- tain cu-cumstances, water from the Furlenbach found its way under the Stockhalder into one of the heads of the fountain supplying Lausen. It was noticed that when the meadows on one side of the Furlen- thal were irrigated, which was done periodically, the flow of water in the Lausen spring was increased, rendering it probable that the irrigation water perco- lated through the superficial strata, and found its way under the Stockhalder by subterranean channels in the limestone rock. Moreover, some years before, a hole on one occasion formed close to the Furlenbach by the sinking-in of the superficial strata, and the stream became diverted into it and disappeared, while shortly after the spring at Lausen began to flow much more abundantly. The hole was filled up, and the Furlenbach resumed its usual course. The Furlenbach was unquestionably contaminated by the privies of the adjacent farm-houses, the soil- pits of which communicated with it. Thus, from time immemorial, whenever the meadows of the Furlen- thal were irrigated, the contaminated water of the Furlenbach, after percolation through the superficial
