"I'm glad we're free at last!" I said, cuddling up to Torrence in the stern of the boat.

"Don't crow before you're cut of the woods!" he answered. "We shan't be safe until we're in the air ship, above the heads of all of them!"

"Not knowing who the them are, I'm not in a position to disagree with you!" I answered.

"Nor to agree with me, either," said he; "but wait 'till we're up in the clouds; then I'll tell you all about it."

The launch trembled under the pressure of steam put upon her. The grim docks, just showing their heads through the darkness, and the black swirling water beneath, made it seem as if we were rushing down some giant millrace. It was the stillest hour of night, and Torrence said we must make Gravesend before dawn, which at that season of the year, would not be long in coming.

As usual, a tremendous fog came piling in from the sea, as we swept down the river; and before reaching our landing, we were enveloped in a dense cloud-like vapor which wet us to the skin. Luckily our pilot knew his business, and I believe that with points of the compass given, and revolutions of the screw, he could have landed us with his eyes shut. However that may have been, we got there without an accident; and when ready to go ashore, I saw Torrence put a pile of money into the hands of each of the men; at the same time, he said:

"Boys, she's yours! I shall never want her again!"

Then leading the way with his lantern, we hastened forward toward Wetherbee's barn.

The air was thick, and the road difficult to find, but we stumbled along without a word, until reaching an old fence, where Torrence suddenly stopped.

"We are nearly there," he said, putting his hand on my shoulder, and speaking impressively. "The air ship is ready to carry us aloft at a touch from my hand; but for certain reasons which I cannot now explain, there is an obstacle in the way of our leaving which we must overcome before the approach, of dawn. It is this. The barn is surrounded by a force of armed men, whose object is to prevent our escape. I will tell you all about this as soon as we are out of their reach; meanwhile, if you, Gurt, will stand by me, and do exactly as I say, we shall outwit them. No human being in this wide world understands the mechanism of this thing but me. At this hour we may reasonably expect those lubberheads to be asleep. We must crawl in among them stealthily, climb up into the machine and be off before one of them suspects that anything is wrong. If by any accident they should be aroused and attempt to detain us, why I intend to plow through them like a reaper in a wheat field. There are, however, two points in this programme which must be carefully observed, and adopted if necessary. The first is, if we are suspected, drop immediately on the ground, and assume to be one of the watchers by feigning sleep, and a due suspicion of the others. Second, if we find them awake and recognizing us, fight if necessary; but reach the air ship under any circumstances, for once in it we can plow them down like chaff. Whatever you do, be sure and take your cue from me, and follow close upon my heels."
