“Yes, sir. Say, Mr. Brown, won’t you speak to the day man and have him keep a sort of watch over the boxes here, so that nobody meddles with them?”

“I will, if you’ll tell me what you’re up to along with them.”

“That’s a bargain—listen,” said Bob.

“Aha!” exclaimed the watchman, as Bob whispered in his ear. “Well, you are two originals, and no mistake! I’ll tell my partner.”

“And keep it a secret until the event comes off?”

“Oh, sure—but what will he tell the fellows who will be snooking around here wanting to know what it all means?”

“Why,” said Bob, “just say—stunts.”

“But they will want to know what kind of stunts.”

“All right,” replied Bob Dallow airily, “tell them we’re going to make some bomb dropping experiments.”
