Six more days were spent in driving holes according to Harry's plan. The result was in all cases the same. Sand and small stones were brought up attached to the grease. They had now sunk the holes at a much more rapid rate than at first, for they were accustomed to the work, their muscles had hardened, and they were able to strike more frequently and with greater force. They would have got on still more quickly had it not been for the trouble in sharpening the drills. These were heated in the small blacksmith's fire Dias had brought. They were first placed in the fire, but this was not sufficiently hot to raise them beyond a dull red glow. When this was done a shovelful of glowing fragments was taken from the fire and placed on the hearth, and among these the small bellows raised the ends of the drills to a white heat, when of course they were easily worked. At first they had some difficulty in tempering them. Sometimes, when cooled, the points were too soft, at other times too brittle; but at the end of a week they had arrived at the proper medium. But one of the party had to work steadily to keep the drills in good order.

Bertie was daily employed at this work, as Jos� generally failed to give the proper temper to the tools. Bertie, however, generally managed to get in two or three hours' work below. Although perfectly ready to do his share, he was by no means sorry to be otherwise employed for a part of the day, and as he was now able to talk Spanish with perfect fluency he and Donna Maria maintained a lively conversation whenever they were together. All the party, however, were glad when Sunday came round and gave them a day of complete rest; then they would bathe, fish, shoot pigeons, or lie in the shade, each according to his fancy, and recommence work with fresh vigour the next morning.

Just a fortnight after they had begun work they were about to begin a hole in a fresh stone. Talking it over, they had come to the conclusion that this was the most likely spot in the cellar for the situation of an underground chamber. Farther on there would scarce be width for one, for it was here but eight feet across. Where they had already tried there would scarcely have been depth enough. This seemed to them to be the happy medium.

Before setting to work Dias passed his torch over the stone. Presently he stopped. "Will you light two of the candles, se�or; the torch flickers too much to see very plainly."

Somewhat surprised, for no such close examination had been made before, the candles were lighted and handed to him. Dias knelt down, and, with his face close to the stone, moved about carefully, examining it for some minutes without speaking.

"This stone, se�or, is broken," he said at last, "broken into a dozen pieces, and they have been so carefully fitted together again that the dust that settled upon it quite prevented our seeing it till we swept it again just now, and it was only because there was a tiny chip out where I first looked that I noticed it."

Harry knelt down and also examined the stone. Like all the others, it had not been faced with tools. Consequently, although roughly even, there were slight irregularities in the surface. Now, as Dias pointed them out to him, he saw that there were lines running through it here and there.

"Look here, se�or. The stone has been struck here. Here are some dents."

These were scarcely noticeable. The surface had taken the same colour as the rest of the stone. They were of irregular size, and from a quarter of an inch to an inch in diameter, and nearly in the centre of the stone, from which point several of the cracks started.

"It certainly looks as if the stone had been struck with something heavy," Harry said. "I should think, by the appearance, some very heavy piece of rock must have been dropped upon it."

"Yes, se�or, very heavy rock—so heavy that there must have been many men to lift it."

"It must have been heavy indeed to break up this slab."

"Perhaps it is not so thick as the others," Dias suggested.

"I don't like it, Dias. Well, let us set to work. We will try the wedges there. They were no use against the solid stone, but they might move these pieces. Put one of the borers just at the place from which these cracks start—at least, I suppose they are cracks—and let us drive it in for an inch. You hold it, Jos�. Don't turn it, we want it to go in just in a line with this crack. I know we cannot drive it in far, but at least we may make it go deep enough to give a wedge a hold in it."

Five such small holes were made in a crack that seemed to form a rough circle, then the wedges were put in, and they began to work with sledges. In ten minutes Harry, examining the place carefully, said: "The bit of stone is breaking up. There are lines running across it from the wedges. Give me the heaviest sledge." He swung it round his head and brought it down half a dozen times in the centre of the wedges. The cracks opened so far that he could see them without stooping.

"Now we will try with the crowbars," he said.

In ten minutes a fragment of the stone was got up; then they hammered on the wedges again, and a piece of rock, which was roughly seven or eight inches in diameter, broke completely off.

"It is only about two and a half inches thick," Harry said as he drew one of the fragments out. And, holding the candle to the hole, he went on: "And there is another slab underneath. That settles it. We are at the top of one of these vaults. The question is, is it empty? I am afraid it is. This stone has evidently been broken up and fitted in again with wonderful care."

"Why should it be fitted in carefully if they emptied the chamber?"

"That I can't tell you, Dias, and it is of no use trying to guess now. First of all, we will get the rest of the stone up. It won't be difficult, for now that we have made a start we can use our crowbars. Jos�, run up and tell my brother to come down. We shall want him to help with the crowbar; and besides, he would, of course, wish to be here, now that we
