rough rocks, except just below our feet, where there is a narrow stone staircase of regularly-cut steps. It is so narrow that it could not be noticed by anyone standing here, unless they bent over to look straight down as I am doing. Well, it is just as well that we made the circuit, for we certainly could not have climbed over there."

Another sharp turn, and the ravine ran straight towards the castle. They hurried on, and when they had gone fifty yards stood at the edge of a roughly circular pit. It was seventy or eighty feet across, narrowing at each end. At one end was the ravine at whose mouth they were standing, and directly opposite, in what might be called the neck of the bottle, stood the Castle of the Demons. It was some fifty feet in width, and as it stood back about forty feet up the neck it could hardly be seen at any point except that at which they were standing. There was no door or other opening at less than some twenty-five feet from the ground. At that height was a broad aperture about four feet high and twelve wide. Above this were several smaller openings about four feet square. The singular point in the structure was a rough arch of rock, which extended above it and formed its roof. This arch projected thirty or forty feet in front of the building, so that the latter had the appearance of standing in a great cave.

"What an extraordinary-looking place!" Bertie said in a low voice.

"Extraordinary, but how splendidly chosen for concealment! You see the top of the rock above it is level with the ground on either side. This would perfectly well account for people riding along the line of the cliffs, and passing over without dreaming that there was a house below them. Even if they went to the edge on this side, they would simply see this deep pit and the ravine beyond, but could not by any possibility obtain a sight of the house unless they came round to nearly where we are standing, which they could have no possible motive for doing. Besides, you see, all the way we have been passing through a thick bush; and I have no doubt that in the old time a wood stood here, possibly planted by the builders of the house. Of course the arch existed before the house was built. The stratum below was probably softer, and the stream gradually trickled through, and perhaps in some great flood, when this basin was full, burst its way out, after which the rock gradually fell until it formed that great natural arch."

"Well, let us go round and have a look at the other side."

They found that the width of the arch to the sea cliff was a hundred and fifty feet.

"If the castle extends to this face, Bertie, it is a hundred feet across, but from here we can't see whether it does so. It is probably built flush, however, as Dias said that it was not noticeable from the sea, and had the arch projected beyond it it could certainly have been seen."

"Well, Harry, if you will tie a rope round my waist you can let me down, and I will have a look at it. You can hold me easily enough if you stand twenty feet back from the edge, and you won't have to pull me up, because I can easily climb up the rope by myself. I need not go down more than thirty or forty feet, and I can do that easily enough."

"Oh, I could pull you up, Bertie."

"Well, you could do that if by any chance I should get tired; then I could give a shout, and you could haul on the rope."

"There are lots of stumps of trees here, Bertie, and I can take half a turn round one of them and so let you down easily; then when you shout I will fasten the rope there and come to the edge, and I can hear whether you want me to haul or not. Of course it must depend whether there are any jagged rocks sticking out. If so, it would be better for you to climb, as the rope might chafe against them if I pulled."

"I understand." Bertie laid down his weapons and water-flask, made a loop at the end of one of the ropes they had brought large enough for him to sit in, then he looked for a spot where the short grass extended to the very edge. "This is a good place, and the rope won't chafe as it runs over that. Now I am ready. If you will go back to that stump fifteen feet away and let it out gradually, I will be off."

He knelt down, and putting the rope over his head took a firm hold of it just above the loop, and then crawled backwards, his brother keeping the rope taut. "Slack it out gradually now," Bertie said; "I am just over."

Directly afterwards his shoulders disappeared. Harry let the rope slowly out until he calculated that fifty feet were over the cliff, then he fastened it very securely round the stump and went forward to the edge.

"Are you all right, Bertie?" he shouted.

"Quite right."

The face of the rock was very even, and there was nothing for the rope to chafe against. Harry lay down at the edge, keeping a firm hold of the rope to prevent himself from slipping over, and was able to look down on Bertie.

"Well, Bertie, what is it?"

"It is the wall of the house, I have no doubt, but it is so cleverly built that I can scarcely see where the arch ends and the house begins. Looking quite close I can see where the stones join, but their face has been left rough; and as it is just the same colour as the rocks, and lines have been cut down its face, and cracks made across it answering to the lines in the rock on both sides, I am sure I should not have known it was built up unless I had examined it. It is much narrower on this side than on the other—not more than twenty-five feet, I should say. There seem to be some irregularly-shaped holes in what looks like a fissure in the middle. I suppose they are to light the rooms on this side of the house, but they are certainly too small to be noticed from the sea."

"Does the sea come right up to the foot of the cliff?"

It was a minute before the answer came. "The water comes to the foot, but there is a line of rocks running along forty or fifty feet farther out. Some of them seem to be thirty feet out of the water; at one end they touch the cliff, and at the other there is a free passage. The water is very clear, but as far as I can judge I should say there is a depth of a fathom or a fathom and a half between the rocks and the cliff. Certainly a boat could row in to a position underneath where I am."

"Is there anything more?"

"No."

"You don't see an entrance down here?"

"No."

"All right! Then you may as well come up again. Can you climb up?"

"Easily."

"Well, hail me if you want me to haul."

Harry went back to the stump, unwound the rope until
