'Yes, willingly,' said the professor, glad to get back again on to the familiar ground of his own experiences. 'I found it almost by accident in a little valley about four days' ride to the westward of Cuzco. I was on my way to Abancay across the Apurimac. My mule had fallen lame, and so I got belated. Night came on, and somehow we got off the track crossing one of the Punas--those elevated tablelands, you know, up among the mountains--and when the mule could go no farther we camped, and the next morning I found myself in an almost circular valley, completely walled in by enormous mountains, save for the narrow, crooked gorge through which we had stumbled by the purest accident. The bottom of this valley was filled by a little lake, and while I was exploring the shores of this I saw, hidden underneath an overhanging ledge of rock, a couple of courses of that wonderful mortarless masonry which the Incas alone seemed to know how to build. I had no sooner seen it than all desire of getting to Abancay or anywhere else had left me. I made my arriero turn the animals loose for the day, and then I sent him back to a village we had passed through the day before to buy more provisions and bring them to me. 'As soon as he had got out of sight I set to work to get some of the stones out and see what there was behind them. I knew there must be something, for the Incas never wasted labour. It was hard work, for the stones were fitted together as perfectly as the pieces of a Chinese puzzle; but at last I got one out and then the rest was easy. Behind the stones I found a little chamber hollowed out of the rock, perfectly clean and dry, and on the floor of this I found, without any other covering than what you see there, the mummy of His Highness lying on what had once been a bed of soft Vicuna skins, as perfect and as lifelike as though he had only crept in there twelve hours before, and had laid down for a good night's rest. 'You may imagine how delighted I was at such a find. I hardly knew how to contain myself until my man came back. I put the stones back into their places as well as I could, and when Patricio returned the next day I had the animals saddled up, and started off in a hurry to Cuzco. There I had this case made, bought two extra mules, brought them to the valley, packed up my mummy, took it back to Cuzco, and from there to the railway terminus at Sicuani and took it down by train to Arequipa, where I left it in safe keeping until I had finished the rest of my exploration. Then I went back, took it down to Mollendo, got it on board the steamer, and here it is.' 'And you didn't find any traces of other treasure-places, I suppose, in the valley?' said Djama, who had listened with the most perfect attention to the professor's story.
