While carrying on the works, several rows of stakes were exposed; and on digging down, the labourers turned up a number of pieces of charred wood, stones blackened by fire, utensils, bones, and other articles, showing that at some remote period, a number of human beings had lived over the spot, in dwellings supported by stakes driven into the bed of the lake.
The discovery having attracted attention, explorations were made at other places, and it was shortly found that there was scarcely a lake in Switzerland which did not yield similar evidence of the existence of an ancient Lacustrine or Lake-dwelling population.

Numbers of their tools and implements were brought to light--stone axes and saws, flint arrowheads, bone needles, and such like--mixed with the bones of wild animals slain in the chase; pieces of old boats, portions of twisted branches, bark, and rough planking, of which their dwellings had been formed, the latter still bearing the marks of the rude tools by which they had been laboriously cut.

In the most ancient, or lowest series of deposits, no traces of metal, either of bronze or iron, were discovered; and it is most probable that these lake-dwellers lived in as primitive a state as the South Sea islanders discovered by Captain Cook, and that the huts over the water in which they lived resembled those found in Papua and Borneo, and the islands of the Salomon group, to this day.
These aboriginal Swiss lake-dwellers seem to have been succeeded by a race of men using tools, implements, and ornaments of bronze.

In some places the remains of this bronze period directly overlay those of the stone period, showing the latter to have been the most ancient; but in others, the village sites are altogether distinct.

The articles with which the metal implements are intermixed, show that considerable progress had been made in the useful arts.
