The American looked puzzled. "Can't say I remember the name, Selim. Where is it?"
"Ah, many men have asked that question!" and Selim's white teeth shone. Charlie stole a glance at Jack. His dreams of the mysterious East were being rapidly realized! "No one has ever answered it, however. It is one of those odd native yarns that are generally founded on fact, though you white men disbelieve them. Here it is for you:
"Two years ago rumors began to drift to certain of us that somewhere, far down from the Abyssinian border in that desolate land north of the Lorian Swamp, there was a lake. The tale was given me in fuller form by one of my own Arabs who had got lost and found his way out to die, crazed and raving of horrible things, only a few months ago.
"This lake, it seems, is fed by underground springs—hot springs, that spout up and fall like fountains on the water; its outlet is also by an underground river, so that the lake lies, sweltering in the sun and surrounded by desert and jungle and marsh, where no people live."
Ben Amoud turned to the calmly interested German. "You, Doctor von Hofe, are a scientist. Granted such a body of water, at an average temperature of ninety to a hundred degrees Fahrenheit; would animal life in it and near it be liable to any change in average size?"
The big man stroked his beard reflectively, pulling at his pipe.
"Possibly," he admitted at length. "But only one way. If animal life could exist at such a temperature, it would perhaps be much larger than elsewhere. For instance, a buffalo lives much in the water. In such a place as that, a buffalo's great-grandchildren would be larger, and so on through succeeding generations, each a little larger. Yes, it iss possible—but nod probable."
"Do you mean," cried Charlie, unable to repress his eagerness, "that there are giant animals there?"
The Arab smiled and waved his hand. "It is but a tale, remember. See, I have heard that in this lake are great serpents of monstrous size. That, as our friend has just said, there are such buffalo there as were never seen, and that evil spirits dwell on an island near the reed-encircled shore. But there is one thing more, that might interest you; indeed, it was my reason for telling you the story.
"Not only the wandering natives, but my own Arab, have raved of a tremendous elephant, a rogue, who dwells near there. He is said to be of great size, very wicked, and cursed by Allah with the desire to fight men. His size is said to be that of a mountain—and in truth I doubt if any man has ever seen him and lived to tell of it. There, my friends, would be a conquest worthy of your skill!"
