Bertie's face brightened as Harry proceeded.
"It certainly seems possible, Harry. Of course the other place seemed so much more likely to us that we have never given the side walls a thought. We may find something there after all. I do hope we may, old boy. I cannot believe that after things have gone altogether so well with us, and we have been twice so near finding treasure, that we should fail after all. Which side shall we begin on?"
"We will have a look at them before we decide, Bertie. We have not really examined them since the first day; I really forget what stores we found in the two side-rooms."
An examination in the morning showed that the passage near the entrance to the rock on the left-hand side had been used for fuel, that on the other side was filled at the upper end with skins for some distance, and spears and sheaves of arrows were piled against the outer wall along the rest of the distance.
"Which do you think is the most likely hiding-place?"
"I should say the right-hand passage. The other with the fire-wood in it might be visited every day, but the spears and arrows would only be wanted in case of any attacks upon the castle, or to arm a large force going out to give battle there. They would naturally put anything they wanted to hide in the passage less likely to be visited."
"That does seem probable," Bertie agreed; "therefore, hurrah for the right-hand side!"
"I still think, señor," Dias said, "that there must be treasure concealed somewhere. I should not think a guard would have been placed here, and remained here so many years still keeping watch, as we find they did at that big loophole on the top floor, unless there was something to watch."
"Quite so, Dias. I have thought that over in every way, and I can see no possible motive for their being here except to prevent the place from being examined. That was needless if there was nothing to guard, and nothing to take away, except these silver brackets, which in those days would scarcely have been worth the trouble of getting out and carrying away. There must be treasure somewhere. We know now that it is not in the basement, and we will try these side walls, even if we have to blow half of them in; there is no doubt that the stones are at least as thick as those at the end, but they will not be difficult to manage. I noticed in the upper story that they had not taken the trouble to fit them nearly so accurately as they did those of the outer walls. I don't say that they didn't fit well, but the stones were of irregular sizes, and I have no doubt that in many places we could prize them out with a crowbar. Once an opening is made, there will be no difficulty in getting a lot of them out, as the old people did not use cement or mortar. Well, to-morrow morning we will move all the spears and arrows across to the other side of that passage and have a good look at the stones, but we will go up first and look at the side walls of all the other rooms and see if they are of the same build. There may be some difference which we have not noticed. You see all the side walls of this room are built like those in front. I didn't notice whether it was the same in the other rooms."
"I will look at once," Dias said, lighting a torch at the fire.
