Not illustrated. 1873 edition. Excerpt: ... in the shape of a half-moon with its concave side toward the glacier. If a long-continued cold temperature sets in, which favors the progress of the glacier, the latter will push before it the moraine, along with a mound of earth, uprooted trees, &c; and if the temperature rises, the lower end of the glacier melts away and the glacier apparently recedes, leaving the moraine at its advanced position as a mark of its extent to future observers. Such advanced moraines are found with nearly all the larger groups of glaciers in Central Europe, some of them miles away from the present end of the glacier, as, for instance, at Berne and Zurich in Switzerland. Mountain-ridges like the Carpathian, which have no ice near them to-day, have ancient moraines. Marienzell rests upon bowlders brought to their present position by glaciers. At the foot of the Rosalia Mountains are found the traces of glaciers which formerly existed on the Wechsel and Schnee Mountains. Since these moraines extend directly across the valleys, they often obstruct the water-courses ami give rise to Alpine lakes. The upper lake of Gosan is bounded toward the valley by the moraine of the western Dachstein glacier. The "Meerange," a lake in the Tatra Mountains, is hemmed in by a similar moraine, although at the present time there is neither a glacier nor even an extensive snow-field in the place. All these moraines are a proof that a much colder temperature must have prevailed in these regions at a time after they possessed their present formation, and if these traces of past glaciers are so numerous in the latitnde of Switzerland, we can easily imagine that they are still more extensive farther north, in Scandinavia. The northern part of Europe also presents other more
