"Thus, then, with Donna Maria riding one of the mules, there would be our five selves and three led mules, of which only one would be laden. That would offer no great temptation to plunderers; and as we shall all have guns across our shoulders, they would see that it would not be worth while to interfere on the very slight chance that the one laden mule might be carrying anything valuable."

"I agree with you, señor. Our appearance would be that of a party of travellers who have been exploring the old ruins, or, as has been done before, endeavouring to ascertain whether the rivers on the east are navigable down to the Amazon. Besides, the bulk of the people here do not forget what they owe to Englishmen, and the fact that you are of that nation would in itself secure good treatment for you among all except desperate men."

Accordingly they started the next morning. Maria rode, in Amazon fashion, on a mule between her husband and Harry. Bertie followed with José, to whose saddle the three baggage mules were attached in single file. They were undisturbed on their journey. Three or four times they were hailed by men on the rocks above as they went through difficult points of the pass. The reply of Dias, that the two gentlemen with him were Englishmen who had been exploring the ruins and doing a little shooting among the hills, generally satisfied them. One or two, however, who enquired what the mule was carrying, were invited by him to come down and see, though at the same time they were informed that the load contained nothing but blankets and cooking vessels, and enough provisions to last them on the way.
