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.
"The old hermit!" whispered Frank. "There he is!"
And, as the boys looked, the aged man, about whom there seemed to be such a mystery, shook his fist at them, and then disappeared behind a clump of bushes.
