“None but cowards give up an undertaking once begun,” answered Siegfried. “Go back to Rhineland yourself, if you are afraid; but you must go alone. You have brought me thus far to meet the dragon of the heath, to win the hoard of the swarthy elves, and to rid the world of a terrible evil. Before the setting of another sun, the deed which you have urged me to do will be done.”
