"Well, I think under those circumstances, Dias, I would have eaten bats myself. It was certainly a clever idea of his to convert them into poultices, though the general opinion is that cold bandages are the best for a sprained ankle."

Then they discussed their plans for the next day. "I know nothing about blasting, señor. You give me instructions, and I will do my best to carry them out; but it is useless for me to talk of what I know nothing about."

"There is a lot of common sense in that, and yet in every work, Dias, sometimes while a skilled man is puzzling how to do a thing a looker-on will suggest a satisfactory plan. That treasure has been buried there I have no doubt whatever. They would never have gone to the labour of paving those cellars as carefully as they have done unless for some special purpose. The floor was undoubtedly made when the house was built, and if we find treasure-chambers there they will be those of the old people. Of course they may have been discovered by the Incas, and when they in turn wanted to bury treasure this place might occur to them as being particularly well fitted to escape search by Spaniards. However, to-morrow we shall learn something more about them. The first thing to do in the morning, when we have brought up the rest of the goods, is to sweep the floors of those chambers carefully. When we have done that we will determine where to set to work."

Two trips brought up the powder and instruments.

"We will take one of the kegs of powder down with us," said Harry, "and leave the other five in the empty room behind this. It is just as well not to have them in this room; the sparks fly about, and some things might catch fire. I don't think there is any real danger, but, at the same time, it is best to be on the safe side."

"There are a dozen pounds of candles in this bundle, señor. You did not tell me to get them, but I thought they might be useful."

"Thank you, Dias! they certainly will be useful. What are they?—tallow?"

"Yes, señor."

"Then before we go down we will get a couple of pieces of flat wood, and drive a peg into each, sharpened at the upper end. Candles stuck on these will stand upright, and we can put them down close to where we are working. They will give a better light than a torch, and leave us all free to use the tools. Did you think of buying some more tinder?"

"Yes, señor, I have five boxes, and half a dozen more flints."
