[163]; Townson visited these mines in the course of his travels in
Hungary, and neither does he make any mention of ice in connection with
them. He describes them as lying south of Teplitz, in a limestone
district, with sandstone in the more immediate neighbourhood. The mines
themselves (copper mines) are in a kind of mica-schist, which the people
call granite. The superintendent of mines informed Reich that one of the
shafts is called the ice-mine, from the fact that when the workmen
attempted to drive a gallery from south to north, they came upon ice
filling up the interstices of the _Haldenstein_, within five fathoms of
the commencement of the gallery. The temperature was so low, and the
expense caused by the frozen mass so great, that the working was
stopped.
The iron mines of Dannemora, eleven leagues from Upsal, contain a large
quantity of ice, according to a manuscript account by Mr.
Over-assessor-of-the-board-of-mines Winkler:[164] Jars, however, in his
_Voyages Metallurgiques_,[165] gives a full description of them without
mentioning the existence of ice.
