In the 1930s and 40s, while the Straight Track Club in Britain was following up the work of Watkins, similar work was being carried out in Germany. In the 1970s some of this German work was brought out of the archives by the Institute of Geomantic Research (Nigel Pennick, Prudence Jones and others) and published in English. On this website works by two researchers, Josef Heinsch and Kurt Gerlach, are republished both in English and in the original German. The articles by Gerlach, which had to be abridged somewhat in the IGR version, are here published in full. I have made a few slight changes to the translations, but for the most part they are as published in the 1970s.
