"Stop, Jimkin! Let them look for us, and have the fun of being surprised by our great discovery."

So both kept quiet, and let the boys shout. By and by they saw their heads bobbing over the drift, and presently Tug came running towards them, with Aleck close behind.

"Why didn't you answer? Didn't you hear us? Hello! Whoop—la! Wood, or I'm a Dutchman!" and all echoed his wild shout, and tried to imitate his dance, until the joy was bumped out of them by sudden falls on the slippery ice.

It was a tree trunk of oak, that had been floating about, frozen into the ice, above the surface of which fully half of it was to be seen. The stubs of the roots were towards them, while the upper end of the tree, which had been a large one, was lost in a drift more than forty feet distant.

"There is enough good wood here," said Aleck, "to keep us warm for two months, if we don't waste it; and we ought to be very thankful."

"Then let's have a fire right away!" Jim exclaimed.

"All right, Youngster," was the Captain's response. "Fetch the axe, and we'll soon light up."

When Jim had disappeared, Katy asked her brother what he had seen.

"Nothing," was the reply. "And it would just be impossible to move half a mile a day in this snow. It's one of the deepest falls I ever saw. We've got to stay here, for all I see, till it melts, or crusts over, or blows away, or something else happens."
