“Most everybody has, I reckon. He’s here on business though, and that sign is for outsiders, yourself included.”

Old Grimshaw pointed to a sign on the big gates of the high board enclosure outside of which he stood on guard. It read: “No Admittance.” The visitor had come strolling from the direction of some summer cottages near a pretty lake close by. Grimshaw surmised that he was one of the smart set spending an outing there.

“Humph!” observed the young man, with a shrug of his shoulders and a scowl. “Pretty independent, aren’t you? I think you’ll change your tune shortly.”

“Is that so?”

“I fancy. I’ll bring somebody with me who will do what he chooses with your precious old airship, and send you about your business, if he feels like it.”

The young man turned on his heel, mad as a hornet, as he spoke. Just then the gate was pushed open, and a bright-faced, athletic young fellow stepped into view.

“What’s the trouble, Mr. Grimshaw?” he asked, pleasantly.

“Another of those pestiferous nuisances, who want to pry into other people’s business, and think they own the world,” grumbled the veteran aeronaut.

“What did he want?”

John Grimshaw told his story.
