"Have you heard of the lake of Titicaca and the ancient ruins of the great city of Tiahuanaco; a city on this continent believed by archæologists to be at least as old as Thebes and the Pyramids?" Monella asked. "_I_ have," Leonard answered, "though I know very little about them. But I believe I was in that country when very young, and had a curious escape from death there." Monella turned his gaze quickly upon the young man. "Tell me about it. What do you remember?" he asked. "Oh, I do not remember anything; I was too young. But I have been _told_ how that my father went somewhere in that district on a prospecting expedition, and, not liking to be separated from my mother, took her with him, and my nurse, Carenna, and myself. Whilst there they came across a small settlement of white people, as I understand, and remained with them some time. There was amongst these people a child of my own age, and so exactly like me, that my nurse grew almost as fond of it as she was of me, and used to like to take the two out together. One day, it seems, we both went to sleep on the grass, and she left us for a few minutes to gather fruit. When she returned a poisonous snake crawled hissing away, and she found the other poor little child had been bitten and was dead. "That's all I know about it. Who the people were, and where the place was, I cannot say. I have always understood, however, that it was somewhere in the direction of Lake Titicaca. But Carenna could tell you more." "And what about this ancient people of yours?" Templemore asked of Monella, who still gazed thoughtfully and inquiringly at Leonard. Templemore had heard of Elwood's early adventure many times before. "High up on the eastern slopes of the great Andes is an extensive plain, as large as the whole of British Guiana," the old man replied. "It is twelve thousand feet above the level of the sea, and there, at that great height, is also the largest lake of South America, Lake Titicaca, over three thousand square miles in extent, on the shores of which was once a mighty city called Tiahuanaco. It is now in ruins; yet, even amongst its ruins, it boasts of some of the oldest and most wonderful monuments in the world. Two thousand feet above this again, are another large plain and another lake, little known to the outside world, being, indeed, almost inaccessible. It was there my people dwelt, and tradition asserts that they retired thither when driven out of Tiahuanaco by some invasion of hordes from other parts of the continent." "Is it a very old language, do you suppose?" Jack asked. "Undoubtedly one of the oldest in the world; and yet not difficult to acquire by those who know the language of Matava and his tribe--as you do. It has some affinity to it." As regards the tongue spoken by the Indians, Leonard had learnt it from Carenna in his childhood; and Templemore had picked up a good deal from the same source, as well as on his hunting expeditions with Leonard and Matava.
