With greedy hands they tore away the sled and clutched at the precious supplies lying underneath. The fear of bringing an avalanche down on their heads was all that kept them from bursting into hearty cheers.

“We are saved,” cried Hamp, as he got hold of the tin box of matches and struck a light.

“Stay right here,” said Jerry. “I’ll be back in a jiffy.”

He snatched a handful of matches, and crawled into the tunnel, striking light after light as he went along. He was quickly out of sight, but in less than five minutes he returned with a flaming lantern.

The next step was to enlarge the space in front of the rocks, and when this was accomplished, the sled was dragged out of the cavity, and the supplies—snowshoes and all—were securely strapped upon it.

Then the return trip was begun. Jerry crawled ahead with the lantern, and Hamp and Brick came after him with the sled. Each angle was safely rounded, and it was a happy moment when the boys entered the cabin.

The first thing they did was to eat a hearty meal, and no banquet could have tasted better than the dry, uncooked food.

“What time is it?” asked Jerry.

“Just four o’clock,” replied Brick, looking-at his watch.

“Then I’ll tell you what we had better do,” resumed Jerry. “If a thaw and rain should come—and it feels pretty close now—the cabin would almost certainly be flooded. Suppose we go back to the storehouse and dig another tunnel clear out to the lake. I’ll bet anything the wind blew the ice clear of snow. Then, if we reach the open air, we can start away from here to-morrow morning and hunt another camp. First, we’ll look up those prospectors.”
