During the winter of 1865-6, when the water was low, Messikommer recognised the site of a pile-dwelling in the Greifensee, near Riedikon, but it has proved of little importance, as only a few objects--some flints and stone celts, fragments of pottery, shells of hazel-nuts, and some grains of barley--were found. Its site was covered with broken stones, and being about 100 feet from the shore, in a depth of 3 or 4 feet even when the water was low, it was difficult to make a satisfactory examination. (B. 126, p. 308.) Traces of a second station are said to have been observed between Riedikon and the village of Greifensee, near where the Aabach enters the lake. (B. 462.) HEIMENLACHEN. Near the village of Heimenlachen, in the Canton of Thurgau, there is a peat-moor covering about 15 acres, in which the peasants while cutting peat were occasionally turning up objects of human industry deeply buried, but they have been either dispersed among the curious or thrown away. A large skull of an ox, supposed to be that of a urus, lay for years exposed among a heap of rubbish, but when subsequently searched for, it could not be found. Among these relics were celts of nephrite, stone hammers, various articles of bone and horn, and some fragments of pottery and basket-work. Mr. Burkhard Raeber, of Weinfelden, drew attention to these current reports, and made some excavations in the moor, in the course of which he discovered numerous piles and some transverse beams which he considered to have belonged to a platform. Another site in the same moor was discovered in 1875, which yielded similar evidence of a pile-dwelling. The woodwork was not encountered till 4 feet of peat had been removed. Mr. Raeber calculates that the settlement was from 80 to 100 yards in length. (B. 182a, 199, and 336.) KRÄHENRIED, NEAR KALTENBRUNNEN IN THURGAU. Mr. Raeber found evidence of the existence of a pile settlement in a peat bog at Krähenried. Here the relic-bed was 5 or 6 feet deep, and contained remains of piles, charcoal, hazel-nuts, fragments of pottery, and a well-made celt of serpentine. The ornamentation on the pottery consisted in many cases of regular rows of dots impressed on a fine quality of paste with a smooth surface. The peat-cutters assured Mr. Raeber that similar objects had been frequently found by them, but, considering them of no value, they were thrown away. (B. 288.) LAKE OF NUSSBAUMEN. In an open valley between Stein and Frauenfield there is a chain of three small lakes, the upper of which goes by the name of Nussbaumen. Here there is an artificial island, on which Mr. Morlot had observed piles and other indications of a lake-dwelling, but the matter has never been thoroughly investigated. According to Morlot, this island measures 110 feet by 60 feet, is surrounded by piles, and has a similar appearance to that in the little lake at Inkwyl. (B. 31, p. 84.) LAKE OF CONSTANCE.
