A knowledge of these discoveries at Ober-Meilen, and of Dr. Keller's opinion in regard to them, soon spread among the surrounding inhabitants, the immediate result of which was a sudden crop of lacustrine explorers, who carried on a vigorous search for similar remains in this and the adjacent lakes. For their guidance were requisitioned all sorts of traditions, stories of submerged cities, of which many abounded, recollections of the occasional finding of implements and weapons of unusual types, etc.; but of greatest service was the local knowledge of fishermen, who, from practical experiences of disasters to their nets and fishing gear, could at once point out numberless localities where large fields of submerged piling were to be found. In the spring of the same year the celebrated station known as the Steinberg, at Nidau, in Lake Bienne, was discovered, as well as numerous other stations in the lakes of Bienne, Neuchâtel, and Geneva; so that before an illustrated account of the Ober-Meilen discovery could appear in the Transactions of the Antiquarian Society of Zürich Dr. Keller had important materials of a similar character from other localities to record. This report, entitled "Die Keltischen Pfahlbauten in den Schweizerseen," appeared towards the close of the year 1854, and at once attracted the attention of archæologists in all countries. Since then lacustrine investigations in search of lake-dwellings have been incessantly carried on, not only in Switzerland, but in many other countries in Europe, with the result that each year has seen an increase in their number, as well as a corresponding enhancement of the archæological value of the materials so discovered.
