There was a tiny iron ladder leading into a small engine-room and stoke-hole combined, and both at once slid down this, and sat upon the floor.
"Now we can talk," said Hal in a whisper. "But first of all let us settle the question whether anyone is aboard. Sit where you are, Gerald. You're a bit blown, and want rest. I'm as fresh as a daisy, and will just go along to the cabin to see if anyone is there."
He went to the end of the boiler, and, discovering a piece of oily waste, carefully lifted the furnace door. A dull glow immediately escaped, lighting the stoke-hole dimly, and showing at once that it contained only themselves.
"Fires banked to last till morning," said Hal in satisfied tones, which he reduced to little more than a whisper. "That shows that no one intends to look at them during the night. Let me see. Yes, the boiler is full, and the pressure gauge shows just a few pounds of steam. No good to us, though; but we'll soon raise it to bursting-point. Now I'm off."
He stirred the fire, and silently closed the door. Then he ascended the tiny ladder, and crawled along the deck till he came to the cabin, which was roofed with a skylight. Feeling in the darkness for the opening, he soon discovered a catch, and pulling the door open, descended without hesitation, but using the utmost caution all the while. It was even darker down below than on deck, and he therefore stood still, for, if he had moved forward, he might well have stumbled blindly across someone sleeping there. But his doubts were quickly set at rest, for the searchlight again came to the rescue, falling upon the launch, and sending a flood of brilliant rays through the skylight.
"Good! It's empty," murmured Hal; "and as it runs right forward into the bows, and right aft to the engine-room, it is clear that we have the boat to ourselves. All the better, say I, for every time we have to silence some fellow we add to our risks; besides, I don't like to be hammering everyone who comes in our way. But now for steam, and a glorious run to the sea. Ah, we'll feed the fires till the plates are red-hot and the funnel melts. Then, when she's trembling with the pressure of the steam in her boiler, we'll set her for the harbor mouth."
He almost clapped his hands in the exuberance of his spirits, for even the least sanguine would have had to admit that now, indeed, success was near at hand. But there was plenty of work to be done, and he returned to the stoke-hole to complete it.
"We've got to make a move soon," he said. "It must be some while after midnight, and daylight will be with us about three o'clock. We'll lift the furnace door again so as to get a good look round. I shall want plenty of fuel close at hand, but it will not do to move more than can possibly be helped till we are out of the harbor; for, on a quiet and still night, sounds, however faint, can be heard a very great distance."
"And when we are out, what then?" asked Gerald.
"Just this, old boy. You'll have to be skipper, and get to the wheel. There is one good point about it, I notice. They've placed it so close to the entrance above that it will be possible to stand on one of the lower rungs of the ladder, and steer without showing much more than your head. No doubt this launch is usually run by one man, who works her engines and wheel alone. That's why they are placed in such handy positions. If we are not discovered, all will be as simple as eating a dinner; but, if we are, then it will be a trifle exciting, and you will have to look out for the bullets. My job is the engine and the furnace. I've played the game before, and know something about it. Now, lend a hand, and go easy, whatever you do. We don't want all those dogs on our track again, if we can avoid it."
