"He is very tall," said Ulric, at last. "I doubt if we shall ever look upon his like again. But saw ye ever such moonlight? I have known days when I could not see so well as I can this night."

"Aye," said Wulf. "I know this moon. It is not such light as ours, for he hath brought it with him. It is the light which the gods make instead of sunlight in his own place, and it will not go south any further than he goeth. But mark the bears!"

"Something troubleth them," said Ulric.

All could see them plainly, and they were like ghosts wandering to and fro among the rugged heaps of the ice floes. They were much scattered and they moved as if they were hunting for something which they could not find, and they were calling often to each other, moaning as if they were in pain or in great discontent. Sometimes as they did so they lifted up their heads toward the moon, but oftener toward the ice king.

"Look at him now!" exclaimed Ulric. "The moon is shining upon him wonderfully.

"It is so," said Tostig, "but I think not of that. Wilt thou note this, that whenever there cometh a boom of the rending ice the bears call out to their mates? More than we do they know of such matters. All such creatures have gods of their own, and we may have offended them. I like it not."

"The gods of the bears will care for the bears!" said Knud. "They have naught to do with men."

Nevertheless, it was a time for men to speak softly concerning such things when powers whom they saw not and knew not were dragging them and their ship along so helplessly. There are times when one feeleth that he can get along well enough without the gods, but this was a different matter. All the vikings talked soberly and they were glad that their jarl was a son of Odin.

It was a strange, solemn, weird night in spite of the moonlight, what with the peril and the moaning bears and the booming ice. After all, they said, Odin himself might not be with them. There had been places, as all men knew, where all the gods had abandoned even the bravest of the Northmen. Men like themselves had died without a sword cut or a spear thrust. All hope of falling in battle might be lost to them among these treacherous ice floes. It was a short night, if there had been aught to measure it by, but to the men on The Sword it seemed long enough. None cared to go under a deck, but there were some who lay down and slept. The moon sank lower and lower and the shadows lengthened across the ice fields, but there was yet a great flood of broken light when Ulric, the son of Brander, uttered a loud cry and put his war horn to his lips. Every man sprang to his feet, for each thought that he had never before heard such a blast as that. A louder sound instantly answered it, but none could tell whether it came from among the ice peaks or from down toward the bottom of the sea.

"The bears are moaning again!" said Knud. He was ever thinking of his bears, but all the rest were hearkening for what might be coming next, and they knew not yet the meaning of Ulric's blast.
