"It couldn't be better! There are sixty or seventy of them in a sort of little ravine three hundred yards away, on the left-hand side of the river. They don't seem to be keeping guard at all, and if they are not more careful to-morrow night we shall take them completely by surprise. We are going to saddle all the mules directly it gets too dark for any of the fellows on the hills to see us, then we must set to work and pull down enough of the barricade here to allow them to pass. We ourselves, when we go down, will cross at that shallow place above here, and go down the river at that side, otherwise we sha'n't be able to cross it except at some distance beyond the other end of the torrent. Of course the mules must go down this side, as we shall want to turn to the right when we get off. We shall make our attack about ten o'clock."

Bertie went off, and three hours later Dias relieved Harry. As soon as it was light the next morning Bertie and José set to work to fill the cases—there were a hundred squibs and fifty large crackers.

Donna Maria after breakfast went out and returned with a number of flexible sticks of about half an inch in diameter; these she carried into her tent, where she shut herself up for the forenoon. When, at one o'clock, she came out with the result of her work, it resembled a chair without legs and with a back about a foot wide and three feet high.

"What in the world have you got there, Donna Maria?" Bertie asked.

"Don't you know?"

"No, I have never seen a thing like it before."

"This is the thing the porters use for carrying weights, and sometimes people, over the Cordilleras. You see that strap near the top goes round the man's forehead, and when there is a weight in the chair these other straps pass over his shoulders and under his arms, and then round whatever is on the seat."

"But what is going to be on the seat?"

"I am," she laughed. "Dias is so overbearing. It had all been arranged nicely, as you know; and then when he spoke to me afterwards he said, 'The first thing to-morrow morning, Maria, you will set to work to make a porter's chair, and I shall carry you down the stream. No words about it, but do as you are told.' Generally Dias lets me have my own way, señor, but when he talks like that, I know that it is useless to argue with him. And perhaps it is best after all, for, as he said to me afterwards, it is a nasty place for men to get along, but for a woman, with her petticoats dragging and trailing round her, it would be almost impossible for her to keep her footing."

"Well, I thought the same thing myself when we were talking about it yesterday," Bertie said. "Of course I did not say anything, but I am sure Dias is right. I found it very hard work to keep my footing, and I really don't believe that I could have done it if I had been dressed as a woman. And Dias can carry you like that?"
