"That is it," Harry said. "You see the roof comes down into the water twenty feet off, and the light has come up under it. They sloped this pa.s.sage to make the water flow out below the surface of the sea, so that the opening could not be seen from without. By the light I should not say that the opening is more than six inches under the water. I don't know how the tides are, but if it is high tide now, the top of the opening would be eighteen inches out of water at low tide, for, as you know, the tide only rises about two feet on this coast. In that case a boat would be able to come in and out at low tide, but of course a man wanting to come in or go out could easily dive under at any time.

Well, that settles that point for the present. It was a clever plan; any amount of water could flow out in flood time, and yet no one who took the trouble to come behind that ledge of rocks we saw would have any idea that there was an opening. I think now that we had better go back, Bertie; in the first place because we can do nothing until we have manufactured a grapnel of some sort, and in the next place because every moment we delay will add to the anxiety of our friends in camp.

We must have been away three hours, I should say."

They ascended the steps, fastened the short rope round a block at the top of the wall across the ravine, and lowered themselves down. They had to proceed with great care while making their way down the slope composed of rough and jagged rocks, Once at the bottom of the ravine, however, they walked briskly on. They had scarcely issued from the entrance when they saw a stir in the camp in the distance and heard a shout of delight, and then Dias dashed off to meet them at the top of his speed.

"Thanks to all the saints, senor, that you are safe! You do not know how we have suffered. We have prayed ever since you started, all of us.

Once or twice I threw myself down in despair, but Maria chided me for having so little faith in G.o.d to keep you from evil, and cheered me by saying that had harm come to you we should a.s.suredly have heard the sound of your guns. Have you been in the castle?"

"No, Dias, we have not been in--for the good reason that we could not get in, because the only entrance is fully twenty-five feet from the ground. We cannot enter until we have made some contrivance by which a rope can be fixed there, or manufactured a ladder, which would be the best way and save a lot of trouble, if we could get a couple of poles long enough. We thought that we would come back when we had seen all there was to be seen outside the place."

The Indian's face fell. "Then you do not know what is in the house, senor?"

"No; but we are certain that there is no one there, and that probably no one has been there for the past two hundred years, and perhaps a good deal longer."

"And the demons have not interfered with you?"

"The demons knew better," Bertie laughed.

"They may not be powerful in the daytime," Dias said in an awed tone.

"It is at night that they would be terrible."

"Well, Dias," Bertie said, "everyone knows that the demons cannot withstand the sign of the cross. All you have to do is to make a small cross, hold it up in front of you and say, '_Vade retro, Satanas!_' and they will fly howling away."

"Seriously," Harry said, "you know it is all bosh about demons, Dias."

"But the church exorcises evil spirits. I have seen a priest go with candles and incense to a haunted house, and drive out the evil spirits there."

"That is to say, Dias, no spirits were ever seen there afterwards, and we may be very certain that no spirits were ever seen there before, though cowardly people might have fancied they saw them. However, to-morrow we shall get inside, and Bertie and I will stop there all night, and if we neither see nor hear anything of them you may be quite sure that there are none there."

"But the traditions say they have strangled many and torn them, senor; their bodies have been found in the daytime and carried off."

"It is quite possible that they were strangled and torn there, but you may be sure that it was the work not of demons, but of the men who were set to guard the place from intruders. Well, those men have gone. We found two skeletons, which must have been there at least a hundred years, perhaps a great deal more. They were lying on the stairs, the only way of getting into the place, and they would have been removed long ago if anyone had been pa.s.sing in or out."

By this time they had arrived at the camp. "I knew you would come back all safe, senors," Donna Maria said triumphantly; "I told Dias so over and over again. But what have you seen?"

"I see something now--or rather I don't see something now that I should like to see," Bertie laughed. "I thought you would have got a good dinner ready for me, but I do not see any signs of its being even begun."

The woman laughed. "I have been too busy praying, senor, and have been keeping up Dias's spirits. I never knew him faint-hearted before, and it really almost frightened me; but I will set about getting dinner at once."

"No, no," Harry said; "we are really not hungry. We had a good meal before we started. So do you three sit down and I will tell you all we have seen."

The three natives listened with intense interest. When he had done, Maria clapped her hands. "It must be a wonderful place," she said. "I wish I had gone with you, I will go to-morrow if you will take me."

"Certainly we will take you, Maria; and I have no doubt that Dias will go too."

"I will go as far as the place," said Dias, "but I will not promise to go in."

"I won't press you, Dias. When we have slept there a night I have no doubt you will become convinced that it is quite safe. And now about the ladder. We shall really want two to be comfortable--one for getting up to the window, that must be made of wood; the other, which will be used for getting up and down the wall in the ravine, may be made of ropes. But I think that that had best be hung from the top of the ravine above it, so as to avoid having to climb over those rough stones at the foot, which are really very awkward. One might very well twist one's ankle among them."

"I will go at once, senor, and get the poles," Dias said. "You may as well come with me, Jose. We pa.s.sed a wood in the valley about five miles off; there we can cut down a couple of young trees. If we put the saddles on two of the riding mules, when we have got the poles clear we can fasten the ends to ropes and trail them behind us."

"We shall also want some of the branches you cut off, Dias. You had better say thirty lengths of about two feet long, so that we may place the rungs nine inches apart. You had better get poles thirty feet long, for we may not have just the height by a couple of feet."

The two natives at once rode off, and the brothers set to work to collect sticks for the fire.

"It is too bad, senors, that this should not have been done while you were away, but we thought of nothing but your danger."

"You were perfectly right, Maria; if we were in peril, you did the best thing of all to obtain help for us. As to the dinner, there is no hurry whatever for it. What have you got to eat?"

"There is nothing, senor, but a few of the fish we fried two days ago, and the ham that we smoked of that bear."

"I will take the line, then, and go down and try to catch some fresh fish," Bertie said. "There is a good-sized pool about half-way between here and the ravine. I might get some fish there."

"I will take my gun, Bertie, and go up to the bushes by the ravine, and see if I can get a bird or two. There is no other shelter anywhere about here."

In half an hour the lad brought a dozen fish into the camp. None of them were above half a pound, but they were nearly of a size.

"These will be very nice," the woman said with a smile as he handed them to her. "I have thrown away the others. I do not think we dried them enough; they were certainly going bad. I have heard your brother fire several times, and as he does not often miss, I have no doubt he will bring us something."

Twenty minutes later Harry was seen coming along. When he arrived he threw down a large bunch of wild pigeons.

"There are ten brace," he said. "That will give us four apiece. I found nothing in the bushes, but I suddenly remembered that when we went across from the ravine to the house, lots of wild pigeons rose from the sides of the rocks. We did not give them a thought at the time, our attention being fixed upon the building. But when I got nothing above, I suddenly remembered them, and concluded that they had their nests in the crannies of the rocks. So I walked along to the top, and as I did so numbers of them flew up. I shot a couple; most of the others soon settled again, but some kept flying round and round, and in ten minutes I got as many as I wanted. Then of course I had to go down into the ravine by the rope and the steps to gather them up. I returned the way we did, by the rope we had left hanging from the top of the wall."

Maria was already at work on the birds. Taking them by the legs, she dipped them for a minute into a pot of boiling water, and as she took them out Bertie pulled off the feathers. Then she cut off the heads and feet, cleaned them, and spitted them on Jose's ramrod, and, raking out a line of embers from the fire, laid the ends of the ramrod on two forked twigs while she attended to the fish.

"But they will be done before the others arrive," Bertie said.

"No, senor; there they come! They will be here in a quarter of an hour.

The cakes are ready and hot, so we will lay the pigeons on them, and they will be nicely flavoured by the time that we have eaten the fish and are ready for them."

Dias and Jose soon arrived at a gallop, with the long poles trailing behind them and a f.a.got of short sticks fastened to each saddle.

"Those are capital poles, Dias," Harry said as he examined them--"strong enough for anything. We will chop notches in them for the rungs to lie in. There will be no fear then of their shifting, which they might do if the lashings stretched. Now, we have got a capital dinner just done to a turn, so you see we have not been lazy while you were away.

"You see," he said, after they had finished breakfast, "my shooting has quite settled the point that no Indians are in the castle. If there had been they would certainly have come to the windows to see who was firing. I kept an eye on the castle between each shot, and saw no signs of any movement. It is a capital thing that so many pigeons live among the rocks. If we content ourselves with say five brace a day, they will last us a long time, and will be a change from salt and dried meat, which we should otherwise have to depend upon, for we cannot be sending away for fresh meat two or three times a week. We can get fish, though I don't suppose that will last very long, for the pool will soon be fished out, and I don't think that there is water enough in other places for fish of that size."

"We can get them from the sea, Harry. We have got plenty of large hooks and lines, which we used on the other side of the mountains. If any of the window openings on that side are large enough, we can let down the lines from there. If not, we can do it from the top where I went down."

"I should not like that," Harry said. "One might slip on that short gra.s.s."

"Well, one could dive out through the pa.s.sage and sit on that ledge of rocks, and fish either inside them or in the sea outside."

"Yes, we might do that, Bertie, and certainly it would be a first-rate thing if we could get plenty of fish. It would keep us in good health and make a nice change. I think to-morrow morning, Dias, we had better fix our camp close up to the mouth of the ravine. Out here in the open valley we can be seen from the hills, and if anyone caught sight of the animals, it would very soon get talked about, and we should have a party down here to see who we were and what we were about."

"Yes, senor, that would be much better. I should not have liked to go nearer this morning; but now that you have been there twice, and have returned safely, I am ready to move."

"It would certainly be better; besides, it would save us a couple of miles' walk each time we wanted a meal. However, when we once set to work I have no doubt we shall establish ourselves in the castle. Of course one of us will come down morning and evening to see to the animals."

As soon as the meal was finished they set to work to make the ladder. A short stick was cut as a guide to the s.p.a.ce that was to be left between the rungs. Bertie and Jose marked off the distances on the two poles, and Dias and Harry with their axes cut the grooves in which the sticks were to lie. Then the poles were laid a foot apart, and the work of pressing the sticks into their places began. They agreed that the ropes should not be cut up, as they would be wanted for fastening on the loads whenever the mules went to fetch food or powder. Two of the head-ropes were used on each side, and a firm job was made.
