The boys stepped into the cavern and looked around. A rude couch had been made of the boughs of spruce and white pine, and saplings had been roughly hewn into a table and two chairs.
"You must have been here some time?" asked Will, pointing to the skins on the floor.
"Several long, dreary weeks," was the reply.
"Did you come here with your father?"
"Yes, we came together."
"Were you with him in Chicago just before he left for Wyoming?"
The boy opened his eyes wider.
"How did you know we were ever in Chicago?" he asked.
"We know more about your father and yourself than you think we do."
"Perhaps," said the boy suspiciously, "I have done wrong in asking you for assistance."
