"They say," responded Ulric, "that there is an open water leading southward, and that if one can find it and will sail into it boldly, fearing nothing, he may follow its leading until he shall find the city of Asgard and the home of the gods. Moreover, there are lands which no foot hath trodden. I would see some of them if they are to be found by sailing not too far."
So said they all, and there were other tales to tell concerning seas and lands.
They still were talking of these things when a loud shout from one of the watchers summoned them, and they rushed out to the gunwales and the decks. The rain was no longer falling and the sky was clear, so that they saw well what was doing. The ice king had not at all lost his grip upon his own floes, but southward was a vast rift in the ice pack. Wide and blue was the open water, but it was not very near them, and as they were looking at it from their icy anchorage the watcher shouted again:
"O Ulric the Jarl, whales! They will come up again from under the floes. I saw them. A great herd!"
Loud voices replied, inquiring, but they ceased, for the herd quickly showed itself. Many and huge were the whales that emerged, and some of them sprang half their length out of the water.
"They are pursued!" exclaimed Knud the Bear. "I have seen them spring in that manner when the swordfish troubled them. But see them flounder now!"
Strange indeed was the confusion and the tumbling about of this herd of the sea. They were beating the waves into foam, and they were plunging hither and thither as if wildly affrighted.
"I think that it is neither the swordfish nor the thrasher," said Tostig the Red, for he had halfway climbed the mast and he was leaning out to see. "O jarl, it is one of the monsters that Hilda hath told us of. She sayeth that only a few are left, for the gods destroyed them lest they should eat up all the whales. Look yonder!"
They were near enough to see, but could not note clearly until a great fragment broke away from the field of ice which carried The Sword. Through that chasm at its outer border there came up a shape which was not the head of a whale. It was long, with vast jaws, and in them were pointed saws of long white teeth, with which it tore terribly the side of a tremendous bull whale that was nearest. But the bull whale turned and fought him, and there was a vast whirling of foamy water, as the two sea creatures struggled against each other, beating with heads and fins and tails, but the vikings could none the better discern the form of the whale's enemy.
"He is a comrade of the ice king," said Wulf the Skater. "Never before was he seen in these waters. He is somewhat like a snake, but with a vast belly. I saw his head once before, long ago. Ten more were with me in the ship, and we had been long storm-driven. The old men told me much about him."
