Fifteen minutes sufficed for breakfast, and then Dan and Kirby left the cabin, motioning to Dean to follow.

Outside the cabin Kirby said, "Have you a handkerchief?"

"Yes," answered Dean, wondering why such a question should be asked.

"Give it to me!"

Dean mechanically obeyed.

Kirby took it, and, folding it, tied it over Dean's eyes.

"Are we going to play blind man's buff?" asked Dean.

"Yes," answered Kirby grimly, "and you are the blind man."

"I should like to know what you have done this for," said Dean, more seriously.

"I can't answer your question, but no harm will come to you if you keep quiet. You are going to take a walk with us."
