"Now, lads," he said, addressing the youths, "I rather think you'll own that Jack Cosgrove knows a thing or two about icebergs."

"I think Fred and I have also learned something, but what are you driving at?"

"We're well up toward Davis Strait, and there's more than a hundred miles of Greenland coast to the south of us. That old berg has struck a bee line for the North Pole, but it won't reach there, eh, Docak?"

"No; soon turn around—go back."

"Now, isn't that one of the strangest things you ever heard of, lads? The place where the 'Mary Jane' went down, afore that berg, three years ago, was mighty nigh the very spot where Docak found us. I remember he brought us ashore in his kayak—"

"Dis same boat," interrupted the native with a grin, perceptible in the twilight.

"There you are, and, if he keeps on, I'll begin to think that one of you chaps is Captain McAlpine himself, and the other Bill Hardin, who was saved with us."

"It is a most remarkable coincidence," said Fred, and Rob added that he had never read or heard anything like it.

But it occurred to Docak that he was not acting the part of hospitable host, by keeping his friends standing on the edge of the sea, while the reminiscences went on. He stooped and drew his boat far up the bank. The tide was at its height, so there was no fear of its playing the trick our friends had suffered. Then he turned about and started inland, the others following in Indian file.

He was treading a path, a foot or more deep in the snow, and worn as hard as a rock. The ascent was gentle, and a hundred yards from the shore he arrived at the entrance to his home, where a surprise awaited the boys.
