"Perhaps it wouldn't be so unkind to me, though," the Western boy declared. "Take me to that place, Bob, and right away. It strikes me I'd just like to get another little whiff of that same wood smell, myself. It wouldn't be the first time I'd followed up a smoke trail."

"Gracious! that sounds interesting, and I hope you can do it, Frank!" breathed Bob, his admiration for his chum awakening once more.

"First of all, get me to that place. Lead off, and I'll be close at your heels. And, Bob, don't forget that spot where you came near having your tumble. Keep your level head about you."

"I'll sure try to, Frank. Come on then."

"Here is the place, Frank," Bob suddenly said, in a cautious whisper.
