Mimer looked it all over. He then held it in a stream of running water in which he had thrown a fine thread. The water carried the thread against the edge of the sword, where it was cut in two. "It is without a fault," cried Mimer with delight. "I can do better than that," answered Siegfried, and he took the sword and broke it into pieces. Again he set to work. For seven more days and seven more nights he was busy at his forge. At the end of that time he brought a polished sword to his master. Mimer looked it over with the greatest care and made ready to test it. He threw the fleeces of twelve sheep into the stream. The current carried them on its bosom to Siegfried's sword. Instantly, each piece was divided as it met the blade. Mimer shouted aloud in his Joy. "Balmung" (for that was the name Siegfried gave the sword) "is the finest weapon man ever made," he cried. Siegfried was now prepared to meet the proud knight of Burgundy. The very first thrust of the sword, Balmung, did the work. The head and shoulders of the giant were severed from the rest of the body. They rolled down the hillside and fell into the Rhine, where they can be seen even now, when the water is clear. At least, so runs the story. The trunk remained on the hilltop and was turned to stone. Soon after this Mimer found that Siegfried longed to see the world and make himself famous. So he bound the sword Balmung to the young prince's side, and told him to seek a certain person, who would give him a fine war-horse. Siegfried went to this man, from whom he obtained a matchless steed. In fact it had descended from the great god Odin's magic horse. Siegfried, you can see, must have lived in a time when men believed in gods and other wonderful beings. He was now all ready for his adventures, but before starting out, Mimer told him of a great treasure of gold guarded by a fearful serpent. This treasure was spread out over a plain called the Glittering Heath. No man had yet been able to take it, because of its terrible guardian. Siegfried was not in the least frightened by the stories he heard of the monster. He started out on his dangerous errand with a heart full of courage. At last, he drew near the plain. He could see it on the other side of the Rhine, from the hilltop where he was standing. With no one to help him, not even taking his magic horse with him, he hurried down the hillside and sprang into a boat on the shore. An old man had charge of the boat, and as he rowed Siegfried across, he gave him good advice. This old man, as it happened, was the god Odin, who loved Siegfried and wished to see him succeed. "Dig a deep trench along the path the serpent has worn on his way to the river when in search of water," said the old boatman. "Hide yourself in the trench, and, as the serpent passes along, you must thrust your sword deep into his body."
