Having finished their supper, they divided the remainder of the food into two portions, which they stowed away in their pockets. They then waited till they had reason to suppose, from hearing no noise ascending the stairs, that the soldiers in the guard-room had gone to sleep.
Having cautiously opened the door, they next examined the steps, and found that they could wrench up those of the upper part of the flight without making much noise. They had to be quick about it, as their candle would soon burn out.
First, having closed the door, they got up seven of the steps, beginning at the uppermost one, till they formed a gap which it would be impossible for a man to spring over. The boards they carried down as they descended, when they found themselves in another storey, the whole of which was occupied by one large room without doors, the reason, of course, why it had not been made their prison.
Their candle had now nearly burned out. Having hung their shoes round their necks, they were able to step softly. Hunting about, they discovered an empty space under the stairs, in which they stowed the pieces of wood.
“Perhaps we might get down by the stairs,” whispered Jack.
“The chances are that we should find a door to stop us at the bottom,” returned Bill. “We must try to get down the outside. The walls are so full of holes that we might manage it, and I am ready to go first and try.”
The question was, on which side should they attempt to make their descent? On looking through the narrow windows, they observed a gleam of light coming out below them on one side; probably that was from the guard-room, and they accordingly fixed on the opposite side, where all was dark. They ran no little chance of breaking their necks, but about that they did not trouble themselves. If a cat could get up, they believed that they could get down, by clinging with toes and fingers, and teeth, if necessary, to the wall.
They, however, made the fullest examination in their power to ascertain the best spot for their descent; they looked out of every window in succession, but at last arrived at the conclusion that the attempt to scramble down a perpendicular wall was too hazardous to be made. They now began to fear that their enterprise must be abandoned, and that they should be compelled to make their way first to a lower storey, which, for what they could tell, might be inhabited; or else that they must descend the creaking stairs, and run a still greater chance of being discovered.
“Here’s another window,” said Bill; “let’s look through that.”
He climbed up to it, and gazed out. Great was his satisfaction to perceive the top of a massive wall a few feet below him. The tower had been a portion of an old castle, and the end of this wall was a mass of ruins, but quite thick enough to enable them to scramble along the top of it, and Bill had no doubt that they thence could easily descend to, the level ground.
