On one of the Danish islands, where old thingsteads, the judgment seats of our forefathers, loom up in the cornfields, and mighty trees raise their heads above the beech forests, there lies a little town of low houses with red roofs. In one of these houses strange things were being prepared on the open stove, over the coals and embers. There was boiling in test tubes, mixing and distilling, and pounding of drugs in mortars. An elderly man was in charge of everything.
