[18] The description of the Stangenkunst in its various modifications is one of the chief topics of the previously cited work of Calvör (footnote 15), and from his and other references it is clear that the subject was also treated extensively by such earlier writers as Lohneyss (1617) and Rössler (1700).

[20] The hauling of ores, as opposed to water, seems to have remained as shown by Agricola until the end of the 17th century. In 1694, however, the famous Swedish engineer Christopher Polhem built at Falun a water-powered conveyer system which brought the ore from the point of origin in the mine to the smelter in a single operation, terminating with the automatic unloading of the buckets (Vogel, op. cit., footnote 10, p. 306).

[22] In 1673 Edward Browne visited Hungary and the Erzgebirge. His report on the trip, A brief account of some travels in diverse parts of Europe (2nd ed., London, 1685, p. 170), says little about machinery, but does not mention flooding as a serious problem. Of an 84-fathom mine called Auff der Halsbrucker, near Freiberg, he says “they are not so much troubled with water, and have very good engines to draw water out.” Yet the chain of dippers and rag and chain pump were evidently fallen into disuse, as they do not appear among the mining machines reported by Fritsche and Wagenbreth as having been described by Lohneyss (1617) or Rössler (1700); and Fritsche and Wagenbreth declare that German hydraulic machinery was able to compete with the steam engine in mine dewatering for some time into the 19th century (op. cit., footnote 14, pp. 111, 112).
