Schimper, one of the best authorities on mosses at the present day, found among the plant-remains under the tufa at the source of the Schussen only mosses of northern or high Alpine forms. Among them was a moss brought from Lapland by Wahlenberg, which, according to Schimper, occurs in Norway near the chalets on the Dovrefjeld, on the borders of eternal snow, and also in Greenland, Labrador, and Canada, and on the highest summits of the Tyrolese Alps and the Sudetic Mountains. It has a special preference for the pools in which the water of the snow and glaciers flows off with its fine sand. There were also found mosses which have now emigrated to cold regions, to Greenland and the Alps. The most numerous animals were the reindeer, and yellow and Arctic foxes, as distinctly Arctic forms; and there were also the brown bear and wolf, a small ox, the hare, the large-headed wild horse--which always occurs in the Drift as the companion of the reindeer--and, lastly, the whistling swan, which now breeds in Spitzbergen or Lapland. There is an absence of all the present animal forms of Upper Swabia, as well as of the extinct Drift animals, either of which would indicate a warmer climate. More decided climatic or biological contrasts than those afforded by the relic-beds at Taubach and the source of the Schussen could not be imagined; here we have with certainty two perfectly different periods before us, but both belonging to the general Drift Era. Although almost all the other places where Drift Man has been found exhibit peculiarities, Taubach and the source of the Schussen seem the best representatives of the two chief types in Europe. Places giving better proof have not yet come to light anywhere in the Old World.
