"'Hurry, my friend,' called out the stranger, whom he had jostled. 'Hurry, the church bell has rung; the bargain is paid.'

"A malicious laugh rang in Martin's ear. He turned and saw the evil-eyed stranger, him of the black velvet cloak and red-plumed cap.

"Mad with fear, Martin bounded up the church steps. He entered the house of worship; but the stranger had said truly it was too late; the bargain was due for the service was ending. Martin Mux turned to leave the church, but at the threshold he fell dead; the stranger had claimed his soul.

"Since that time it has been the custom for every locksmith apprentice, whether he comes into Vienna to seek his fortunes, or whether he goes out from Vienna to other parts, to drive a nail into the stump of the larch-tree and offer up a prayer for the peace of Martin Mux's soul. That is why the old tree is so studded with nails."

"What a dreadful bargain for Martin to make!" said Teresa fearfully. "How could he have given his soul away?"

"He chose the easier way out of a small difficulty, and he paid dearly for it," replied Herr Müller. "It is not always the easiest way which is the wisest, after all."
