"But if it had been out of doors," Sammy grumbled, "where there weren't any lamps and things, it would have worked fine. I tell you, Tess, we could string it from your house to mine, and the carrier could be loaded up at one station and unloaded and loaded again at the other. Crickey, it would be fun!"

"But maybe Ruthie wouldn't let us do it," suggested Tess, beginning to be enamored of the boy's idea, yet having her doubts about the feasibility of the plan. "It would knock people's hats off."

"What would!" gasped Sammy.

"The wire—or the airship traveling back and forth."

"Oh, Je-ru-sa-lem,'" again exploded Sammy. "You wanted an airship, didn't you? 'Way up in the air—not so's you can reach it from the ground. Why, we'll string the wire from my bedroom window to one of the windows of the room you and Dot sleep in."

"Oh!" cried Dot, beginning to visualize the scheme now. "Just like the cash-carriers in the Five and Ten Cent Store."

"But Ruthie wouldn't let us, I'm afraid," murmured Tess, still doubtful.

"Let's ask her," said Sammy.

"Oh, let's!" cried Dot.
