"No, señor," he said, when in ten minutes he returned; "none of the walls on this floor are built of stone like this. This was the grand chamber, the stones are all nearly one size, and so well fitted that you can hardly see where they join each other. In the other rooms they are not so, but the stones are, as you noticed above, irregular in size, and although they fit closely, there is no attempt to conceal the cracks."
"Thank you, Dias! Well, we won't look any more to-night; we shall see in the morning if the room below us is built in the same way. I have no doubt it is. At any rate we have done enough for to-day. There is some whisky left in that bottle, Bertie, and we may as well make ourselves a glass of grog. Maria, you had better get down that jar of pulque. We will drink to better luck next time."
The woman smiled faintly. She did not often do so now, her spirits had gradually gone down as the hopes of success faded.
"Now, Maria," Harry said, "you had better take a glass of pulque for yourself. I know you don't often touch it, but you have been working so of late that I think you want it more than any of us."
"I cannot help feeling low-spirited, señor," she said. "I have so hoped that you would find the treasure you wanted, and marry this lady you love, and it would be such joy for us to have in some small way repaid the service you rendered us, that I felt quite broken down. I know I ought not to have been, when you and your brother bear the disappointment so bravely."
"'It is of no use crying over spilt milk', which is an English saying, Maria. Besides, it is possible that the milk may not be spilt yet, and until lately your good spirits have helped us greatly to keep ours up. If I were once convinced that we had failed, I have no doubt I should feel hard hit; but I am a long way from giving up hope yet. There is treasure here, and if I have to blow up the whole of the old place I will find it. I have got six months yet, and in six months one can do wonders. Anyhow, these brackets will pay us very well for our work. I certainly should not have earned half the sum in any other way in the same time. And even if I fail in my great object, I shall have the satisfaction of knowing that I have done all in my power to gain it. She will know that I have done my best. I have always told her, when I have written, how much I owe to you and Dias, how faithfully you have served me, and how you have always been so bright and pleasant. I have no doubt it has cheered her up as well as me."
Maria was wiping her eyes now. "You are too good, señor; it is so little I can do, or Dias either, to show our gratitude."
"Nonsense! You show it in every way, even in the matter-of-fact way of always giving us excellent food, which is by no means unimportant. Now we will all turn in, and make a fresh start to-morrow morning."
They were up at daybreak, and after taking their usual cup of coffee lit the torches and descended the stairs to the floor below.
As soon as they reached the right-hand wall, Harry exclaimed: "Why, this is built in the same way as the one we have left! The stones are squared and fitted together as closely as those in the drawing-room. Then why should that be, except in that one room? The side walls all the way up are roughly built. Why should they have taken the trouble on this floor to build these, which are only meant as store-rooms, when even in the rooms above, which were meant for the habitation of the chief and his family, the rough work was deemed sufficiently good? There must have been some motive for this, Dias."
