"Think I'll pitch my camp by your fire to-night, if you haven't any objection," announced the visitor.

"You are quite welcome," offered Tom. "If you wish to, you can bunk in with the lieutenant and myself. There is room for three in our tent. We could not think of letting you sleep outside in this chill air."

"Outside for me," answered Mr. Long. "Must have air and plenty of it. You see I heat it up inside of me and use it later to sell my goods. A promoter, you know, must depend upon hot air because what he's selling won't float on cold air."

Grace brought out blankets and a pneumatic pillow which she placed in a heap near the fire.

"Make up your bed on the softest spot you can find, Mr. Long, though I do not believe there is much choice," said Grace. Then, in a lower voice: "I hope you may not find it necessary to shoot any more mountaineers to-night, Mr. Long."

"Sh—h—h—h—h!" warned the Mystery Man. "I don't know what you're talking about," he added in a louder tone, observing that Washington Washington was standing close by, all eyes and ears.

Grace walked away laughing, Jeremiah Long observing her with twinkling eyes, a quizzical smile on his face.
