However, for once George proved to be a truthful prophet. By the time those five minutes were up, he had succeeded in coaxing the refractory motor to behave itself; and suddenly the Wireless shot off amid a rattling volley of explosions that told full well how her muffler was cut out.

George continued on at a pace that took him far ahead of the rest. Then they saw him draw up and wait, as though, having demonstrated the ability of his motor to do good work, caution again dictated that he keep in touch with the supply boat and the pilot craft.

That day was the easiest of the week. They had an open passage nearly all the way to the bay, the weather was all that could be asked; and the rest did seem so fine after so much hard labor with push poles.

"If this sort of thing would only keep up," Nick remarked, as they landed on a sandspit to make a fire and have a pot of hot coffee at noon, in order to cheer things up, "I'd have some hope of getting back to my former condition again."

"Well, if that means taking up any more room aboard my boat," grunted George, "I hope you won't do it. Things are getting to a pass now that I'm feeling squeezed half the time. Some day we hope you're going to have that ferryboat made to order, as you've been threatening. Say, it'll just be a jim dandy, I guess."

"It's going to combine speed with comfort," declared Nick, unblushingly. "While it'll beat Herb's tub all hollow for room, at the same time it can make rings around the poor old Wireless. Just you wait; I've got her all mapped out in my head, and some day I'll surprise the bunch."

The afternoon run took them in good time to where the sound they were following broke into Charleston Bay.

"There's the ruins of old Fort Sumter!" cried Nick, as they saw the lovely panorama spread out in front of them.

"And Port Moultrie, too! Gee! to think that we'd ever get to set eyes on the places we used to read so much about in history," said Josh, staring around.

"Well," laughed Jack, "to my mind right now, the best of it is that yonder lies Charleston, where we can lay in a new supply of gas; because I'm expecting to find any minute that my well has gone dry. It's an awful thing to have a thirsty engine and nothing to feed it. But perhaps I'll pull through by making every drop tell."
