At the foot of the Fern Alp, about two miles from Nassereit, lies a small deep green Alpine See, and on a rock, which overhangs it, stands the old castle of Sigmundsburg. Beneath the walls of the castle are deep vaults, hewn in the solid rock, in which is buried an incalculable treasure, whose guardian has the form of a big hairy black dog. Sometimes, too, the dog appears like a luminous mass, without, however, burning; in his mouth he holds a key, which opens the door of the treasure-room, but the conditions on which the treasure can be got at are unknown to any one. Besides, the cellar is so well guarded that it is very difficult to approach it; and people say that most probably the Sigmundsburg must fall into ruins before the cellar can be entered, and then only the treasure-guardian may have the chance of finding the redemptor, for whom he is already so long waiting; but before that moment arrives, two centuries will perhaps still have to elapse.
