"No use of that in the night-time, Toby," remonstrated Ty; "mebbe to-morrow we'll get a blanket brigade to stand below while you make your first jump, so's to let you down easy if the old thing breaks."

"No danger of that, Ty; because I've gone all over it again and again, and right now she could sustain a weight of half a ton, I reckon. But it's good of you to be interested enough in my invention to lend a helping hand. Think what it'll mean to all the tribe of aeronauts when every flier is equipped with a Jones Life-saving Parachute, that is guaranteed to float him softly to the ground even if he has a breakdown accident a mile up in the clouds."

Toby after that fell into a musing spell. Perhaps in imagination he peopled the air fairly filled with flitting aeroplanes, and every single aviator supplied with the remarkable device that was going to make the name of Jones the most famous in all the wide land.

The other scouts chatted, and exchanged all sorts of lively remarks. They even indulged in several songs that sounded very strange when heard among those whispering pines of the grove, and knowing as they did what manner of house stood close by, with a halo of mystery surrounding it.

Just as Chatz had predicted the moon arose close on ten o'clock. It was no longer as round as a shield, but had an end lopped off; still the flood of mellow light that came from the lantern in the sky was very acceptable to the scouts, and served to render their intended mission less objectionable.

Finally Elmer arose, and there was a start on the part of those who had been selected to accompany the leader and Chatz on their singular errand.

"I hope you'll let me carry the gun, Elmer?" Lil Artha remarked, coaxingly.

"Why should you?" replied the other, instantly; "if it is a real ghost a bullet wouldn't hurt a bit; and if it should turn out to be some one playing a mad prank I don't think you'd feel easy in your mind if you were tempted to shoot him."

"But it might be some tramp or hard case, and we'd want to subdue him; how about that, Elmer?" questioned Toby.

"Well, we can carry clubs if we like," said Elmer; "and I mean to have a piece of stout rope, so we can tie him up if we overpower him. Six scouts can put up a pretty hefty sort of fight, it strikes me, if things get to that point. No, leave the gun for the defenders of the camp and the grub."
