may have used both methods. However, it doesn't matter to us much how they did it. It is clear that they could in some way or other cut stones. As they took the trouble to do so here, we may conclude that they were anxious to have a smooth floor that would be extremely difficult to get up.

"They would never have taken all this trouble if they had merely been making a floor for a cellar. For that purpose it would only have been necessary to throw rocks and stones of all sizes into the vacant space below, and when it was nearly full, to level it with small stones and sand. That they chose to undertake such tremendous labour as the making of so regular a floor as this must have been, shows that they had some very strong motive for doing so."

Going carefully along the track they had cleared, they found that the stones were of different sizes; some were but two feet wide, others as much as ten, but all fitted so closely together that it was difficult to see the joints.

"It is going to be a hard job to get these out, Bertie," Harry said, when they had completed their examination, "and it is lucky for us that the room gradually narrows from sixteen feet wide to two at the other end, and when we stepped it we made it eighty feet long. We need not take up the stones near the rock wall, for the ravine would naturally narrow as it went lower, and the depth would be greatest by the side of the wall of the tunnel."

"Well, we shall soon blow up the stones when we have got the powder."

"I hope so, Bertie; but I see that we shall have difficulty unless these top stones are extraordinarily thick."

Bertie looked surprised. "Why, I should have thought the thicker they were the more difficult to break up."

"Beyond a certain point that would be so. But suppose they are six inches thick, you may take it for granted that underneath there will be rubble, loose stuff, except where any chambers may be built. If we were to bore a hole through this top layer the powder, instead of splitting the stones up, would expend its force among the loose stuff beneath it; and besides, instead of remaining in its place, it might get scattered, and we would then get no explosion at all."

"Then we should only have to make the hole four inches deep, Harry?"

"As a result of which there would only be two inches of tamping over the powder, and this would blow right out, as if from a little mortar, and would have no effect whatever upon the stone. I have no doubt that we shall find some way to get over these difficulties, but it is evident that the work will not be all clear sailing."

"Of course we shall manage it somehow, Harry, even if we have to smash up all the stones with the sledge-hammers Dias will bring us."

"Is breakfast nearly ready, se�ora? That swim in the sea has given us a prodigious appetite. Did you enjoy it?"

Maria nodded.

"It is very nice, se�or; but I should have liked it better if the water had not been so blue. It seems so strange bathing in blue water."

"You will soon get accustomed to it," Bertie laughed. "There are no pools except that one two miles up the valley. Besides, it is much nicer to have a great bathing chamber all to yourself. Here comes Jos�!"

"Well, Jos�, are the mules all right?" he shouted.

"Yes, but I had difficulty in catching them. They had evidently been frightened by something, and were three miles up the valley with their coats all staring. It must have been either a puma or a jaguar. Of course they must have got wind of him in time; but as, fortunately, they were not tethered, they were able to get away from him."

"I should think he must be up somewhere among the bushes, Jos�," Harry said. "We had better go down tonight and see if he returns again. We shall be losing some of the mules if we don't put a stop to his marauding. Besides, it will be very dangerous for you, Jos�, cutting the wood up there, if he is lurking somewhere. It is fortunate that you escaped yesterday."

"I expect he was on the other side of the ravine, se�or; and even if he had not been, the sound of the chopping would have scared him. They will not often attack in the daytime."

When they had finished their breakfast Jos� asked what he should do next.

"There is nothing else to do, so it would be as well to take our pickaxes and get some of those brackets out of the walls. We will begin with the other rooms of this floor and leave these here till the last."

"I will come and hold a torch for you, se�ors," Maria said. "I like to be doing something. I will wash up first, and then I shall have nothing to do till it is time to get ready for dinner. Now I know there is a savage beast about I should not like to go down the ladder."

"There is very little chance of his coming down the rocks," Harry said. "He is more likely to be lying somewhere on the other side watching the mules."

No move was made until the woman was ready to start. Then they lit two torches. She took one and Bertie the other, while Jos� and Harry took two picks. It was hard work, for the brackets were driven far into the pillars and walls. It was necessary to knock away the stones round them to a depth of two or three inches before they could be got out. They worked one at each side of a bracket, relieving each other by turns, and after four hours' work only eighteen brackets had been got out. As far as they could tell by lifting them, the weight was somewhat greater than they had at first supposed. Harry could hold one out in each hand for a minute and a half, Bertie and Jos� for a little over half a minute, and they agreed that they must be about twenty pounds each.

By this time their shoulders ached, and it was agreed that they had done a good day's work. For the rest of the day they did nothing but sit on the sill of the window and smoke quietly. The next day's work was similar, and twenty more brackets were got out. Late in the afternoon they saw Dias coming down the steps, and at once went down the ladder to meet him.

"Have you got everything, Dias?"

"I think so, se�or, and I can tell you that the mules have had a pretty heavy load to bring back."

"Well, we will go with you at once, Dias, and bring some of the things up. I expect you have had nothing to eat since the morning. Before you do anything else you had better go in. Your wife has been keeping a dish hot for you, as she did not know when you might arrive."

"I shall not be long before I come and help you, se�or. I have unsaddled the mules and turned them out to graze."

"It is just as well, Dias, for there
