“That is strange,” said Leif, somewhat perplexed; “I had fancied that you brothers loved each other passing well; but I suppose that a man who can be guilty of ingratitude is not to be much depended on in the matter of affection.”

Heika winced at these words—not that the charge of ingratitude affected him, but he could not submit calmly to the unjust supposition that in his contemplated flight he had been actuated by selfish indifference to his brother. At the same time he would not condescend to give any explanation of his conduct. Drawing himself up, he looked Leif full in the face.

“Norseman,” he said, “small is the gratitude I owe to thee. ’Tis true, ye have treated me and my brother kindly since we came hither, and for that I owe thee thanks, and would gladly have paid this debt before leaving, had such been consistent with flight; but kindness, however great, is not a worthy price for liberty, and when King Olaf Tryggvisson sent me to thee, I made no promise to sell my liberty at such a price. But in regard to Hake—”

“Ay, in regard to Hake, go on; why dost thou stop?” said Leif, in a stern tone. “There is some truth in what ye say about gratitude; but what of Hake?”

The Scot still remained silent, with his lips compressed, and dropped his eyes sternly on the ground.

“This seems to me a bad business,” said Karlsefin, who had hitherto listened with an expression of anxiety and disappointment gradually deepening on his countenance. “I had thought better of thee, Heika. Surely Hake’s longing to be free and in his own native land must be to the full as strong as thine. I am puzzled, moreover, for two were better than one in the mad voyage ye thought to undertake.”

Heika smiled at this.

“Truly,” he said, “my brother loves his native land and freedom, nevertheless he prefers bondage to freedom, and Greenland to his native land. And yet would he fain have sacrificed his preference, and resigned his bondage out of love to me, if I would have allowed him.”

“Resigned his bondage, Heika!” exclaimed Leif. “Ye speak in riddles, man; what mean you?”

Instead of replying the Scot looked at Leif with an intelligent smile, and held up his forefinger as if to call attention. At the same moment the sound as if of some one running at full speed was heard faintly in the distance.
