Legends of Rubezahl, or Number-Nip
Once upon a time a glazier who was travelling across the mountains, feeling very tired from the heavy load of glass which he was carrying, began to look about to discover a place where he might rest it. Rubezahl, who had been watching for some time, no sooner saw this than he changed himself into a little mound, which the glazier not long afterwards discovered in his way, and on which, well pleased, he proposed to seat himself. But his joy was not of long continuance, for he had not sat there many minutes before the heap vanished from under him so rapidly, that the poor glazier fell to the ground with his glass, which was by the fall smashed into a thousand pieces.
The poor fellow arose from the ground and looked around him, but the mound of earth on which he had before seated himself was no longer visible. Then he began bitterly to lament, and to sigh with heartfelt sorrow over his untoward fate. At length he started once more on his journey. Upon this Rubezahl, assuming the appearance of a traveller, accosted him, and inquired why he so lamented, and what was the great sorrow with which he was afflicted. The glazier related to him the whole affair, how that, being weary, he had seated himself upon a mound by the wayside, how this had suddenly overthrown him, and broken to pieces his whole stock of glass, which was well worth eight dollars, and how, in short, the mound itself had suddenly disappeared. He declared that he knew not in the least how to recover his loss and bring the business to a good ending. The compassionate mountain sprite comforted him, told him who he was, and that he himself had played him the trick, and at the same time bade him be of good cheer, for his losses should be made good to him.
Upon this Rubezahl transformed himself into an ass, and directed the glazier to sell him at the mill which lay at the foot of the mountain, and to be sure to make off with the purchase-money as quickly as possible. The glazier accordingly immediately bestrode the transformed mountain sprite, and rode him down the mountain to the mill, where he offered him for sale to the miller at the price of ten dollars.
