As they calculated that the tower was sixty feet in height, it was considered that thirty pegs, at least, would be required to reach the top. As soon as it was daylight they searched about for some hard wood, which, on being found, they set to work diligently to form into pegs. Its hardness made the operation a slow one, and they had to use great care for fear of turning the edges of their tools. Buxsoo was totally unaccustomed to the sort of work. Dick, indeed, had cut three pegs before either of the rest of the party had completed one. Reginald constantly looked out in the direction Sambro had taken, in the expectation of seeing him return with some tidings or other from the fort. But the day wore on and he did not appear. As he had taken provisions with him, they knew that he could remain at his post without any necessity for coming back for food, and they concluded, therefore, that nothing had occurred worth communicating.
Eager to carry their plan into execution, Reginald proposed returning to the tower without further delay, when a rustle was heard in the bushes, and Sambro crept up to the camp. He had seen, he said, several lights streaming from the upper part of the building, which made him suppose that there must be a good many people within. Still, as they could have no suspicion of the attempt about to be made, they would probably not interfere with their proceedings, and he thought that they might at all events commence operations without delay. Each of them, therefore, carrying a bundle of pegs, they crept back to the foot of the tower. Dick wisely selected the dark side, looking the same way as the back of the temple, on which the moon, when she got up, would not shine, and at once began fixing in the pegs. He soon found that he could not place them one above another, but had to choose the spots from which the plaster had fallen out; so that the pegs were sometimes on one side and sometimes on another. He could have proceeded much faster had he been able to use a stone for driving them in; but, of course, the noise that would have made would have led to the discovery of their proceedings. Up and up Dick climbed, fastening the rope securely to the pegs, so that did one come out he might save himself by the rope fixed to the others. Perseverance overcomes all difficulties. The end of the rope which hung down enabled him to haul up the other pegs as they were required.
At length he reached the parapet, and, climbing over, found himself standing on a flat roof. Reginald climbed up next, carrying the rope by which it was proposed to lower Nuna down. Sambro followed them, though, less accustomed to climbing than Reginald and Dick, he had much more difficulty than they had in getting up. Buxsoo remained below to keep watch, and to receive Nuna on her arrival at the bottom.
On searching about, a trap-door was found in the roof. It was easily lifted. Reginald stationed Sambro at the top, whilst he, revolver in hand, and followed by Dick, descended a flight of stone steps, carefully feeling his way, and not knowing what was at the bottom. By this time the moon was up, and her light streaming through the open trap enabled him to ascertain that he was in a large unfurnished chamber. Carefully groping his way round, he discovered another flight of steps, leading to the lower storey. He and Dick cautiously descended, feeling the wall with their hands, on the chance of discovering the door of a lower chamber, which they guessed must exist. They were right in their conjectures. Not only was a door found, but through the chinks proceeded the light of a lamp burning within. Could Nuna be there? That such was the case was probable; but the room, on the other hand, might be tenanted by a party of armed men, and should they open the door, there would be no little danger in finding themselves among them. The steps, it was evident, continued on to the lower part of the building. There might be other chambers, one of which might be that occupied by Nuna. Should they enter, or descend to the bottom of the tower? They listened at the door, but no sound came forth. This made Reginald believe that Nuna must be its occupant. Still, he thought it prudent to explore the lower part of the building before attempting to gain an entrance. He and Dick therefore descended, till he calculated that they were close at the bottom; and here they were stopped by a door. They remained perfectly quiet, when the sound of loud snoring reached their ears. Listening, they were convinced that it came from the other side of the door; and probably was produced by a sentry, either leaning against it or sitting on the ground. This convinced Reginald that the upper chamber was not occupied by armed men, and he therefore made a signal to Dick to reascend the steps. They crept carefully up, so as to avoid creating any noise which might awake the slumbering sentry.
On reaching the door, through which the light could still be discerned, he knocked gently, and putting his mouth to one of the crevices, he uttered Nuna’s name in a low tone.
“Who is there?” was asked in a voice which he felt sure was his sister’s.
He told her who he was, and that he had come to rescue her; when, a bolt being withdrawn, the door was opened, and there stood Nuna, pale and trembling with agitation. As there was no time to be lost, Reginald briefly told her that he had, with the rajah’s permission, set out on an expedition to find her, and had been happily directed to the right spot.
“I have much more to tell you,” he added, “but only understand that I have every right to protect you, and will do so with my life. Trust to me, and I hope to carry you back safely to your grandfather.”
“I place perfect confidence in you,” she answered.
He took her hand and led her up the steps to the top of the tower, preceded by Dick Thuddichum; and as soon as they had passed though the trap, Sambro gently closed it. Dick now lost no time in uncoiling the lengths of rope he had brought to the top for the purpose they had in view. To one end was attached a sort of cradle which he had thoughtfully constructed.
