Mines on the Eisenberg. (Fugger, Eishöhlen, page 59.)—These lie near Blankenburg in the Thüringer Wald and have been known to contain ice.
The Ziegenloch or Grosses Kalte Loch, and the Kleines Kalte Loch. (Behrens, Hercynia Curiosa, pages 68, 70.)—These lie near Questenberg in the Southern Harz Mountains, at an altitude of about 300 meters. The Grosses Loch is described as a sort of small pit some 8 meters deep, in one side of which opens a small fissure some 10 meters long. Ice has been found in this in April; Schwalbe found none there in July. The Kleines Loch was another small cold cave near the Ziegenloch, but it has been filled up. Behrens says that the dampness at the cave at Questenberg is precipitated as snow.
Holes with Ice near Sanct Blasien. (Fugger, Eishöhlen, page 109.)—In the Black Forest, among boulders at an altitude of 820 meters.
Holes with Ice near Hochenschwand. (Fugger, Eishöhlen, page 109.)—In the Black Forest, among boulders at an altitude of 820 meters.
Eisstollen and Eiskeller at the Dornburg. Described in Part I., [page 59]. (Poggendorff’s Annalen der Physik und Chemie, Ergänzungsband, 1842, pages 517-519.)—Ice appears to have been discovered at the Dornburg in June, 1839. It was found from a depth of 60 centimeters down to 8 meters. The width of the ice-bearing talus was from 12 meters to 15 meters; and it is said that it becomes wider in winter and narrower in summer.
Beschertgluck Mine, Freiberg District. (Prestwich, Collected papers, etc., page 206.)—Mr. Prestwich quotes Daubuisson as having seen the shaft of the mine lined with ice to a depth of 80 toises (144 meters?).
Ice in the Zinc Mines on the Sauberg. (Reich, Beobachtungen über die Temperatur des Gesteines, 1834, pages 175 and 205.)—These are near Ehrenfriedersdorf in Saxony and formerly contained ice in winter. They are reported now to be destroyed.
The Garische Stollen. (Lohman, Das Höhleneis, etc., page 3.)—Near Ehrenfriedersdorf in the Freiwald. Lohman found much ice in this in January, less in March, and scarcely any in May.
