"Hardly. If we were in a savage country I could understand the natives firing at some such object as this airship, but the people of that city must have known what our craft was. They probably have read something about it in the news papers, and to deliberately fire on us, with the chance of disabling us, seems worse than barbarous."

"Well, we won't give 'em another opportunity," commented Mr. Damon.

"No, indeed, not this city, but who knows but what the example may spread? We may be fired at the next town we sail over."

"Then steer clear of the towns," advised Tom.

"Impossible. We must pass over some, but I'd like to solve this mystery."

The day passed without further incident, though they did not go low enough down over any city to drop any messages. It was decided that it would not be safe.

"We'll take a chance at night," suggested Tom, and that evening, approaching a good-sized town in the dusk, several of the weighted envelopes were dropped overboard. Doubtless persons walking along the street, who were startled by hearing something fall with a "thud" at their feet, were much startled to look up and see, dimly, a great, ghostly shape moving in the air. But there was no shooting, and, eventually, some of the messages reached Mr. Swift, in Shopton. But he could not answer them for the airship kept on the move.

The night was spent floating in the air, with the engine stopped, and the Red Cloud floating lazily this way and that as the gentle winds shifted, for it was calm. The "anchorage" if such it may be called, was above a sparsely settled part of the country, and if the lights of the airship were seen from below, the farmers doubtless took them for some new stars or, possibly, a comet.

"Now then for a fast, straight run!" cried Tom, after breakfast had been served, and the big motor, with its twenty cylinders, started. "We'll be able to make the turn to-day, and then make for home, won't we, Mr. Sharp?"

"Well, we could do it, Tom," was the answer, "but I like this mode of traveling so that I think I'll lengthen the voyage. Instead of turning at Atlanta, what do you say to making for Key West, and then starting back? That will be something of a trip. The Red Cloud is behaving much better than I hoped she would."
