"Say, that would be fine!" cried Frank. "It may happen, too. We'll wait a bit about going back."

They decided this would be a fair thing to do, and, after putting the cabin to rights, after their morning meal, and planning what they would have for dinner, they set out for a tramp about the island, Maybe the dog going with them.

They went on for half a mile, when Bob, who was in the lead, suddenly stopped, and called out:

"There's somebody moving over there!"

"Over where?" asked Sammy.

"There," answered Bob, pointing to a clump of trees, at the foot of which was a bank of snow. "I just saw a man."

"Maybe it's Mr. Jessup," spoke Frank.

"I hope so," murmured Sammy. "I'd like to get after those men who live in the secret room."

And then, as the boys watched, the figure of an old man came out from a clump of bushes. The man had a long white beard, and white hair, and as he came into a little opening he looked in the direction of the boys.
