"Yes, sir, he can do that." "And you said yourself the other day that he could track the bucks splendidly." "Yes, sir. You see, he's used to it." "And we have never wanted for game since we have come to Africa." "That we haven't, sir," said Bob Bacon. "Then he is some use, after all," cried Mark. That night, with their strange surroundings wonderfully illuminated by the glowing fire, and a feeling of safety infused by the knowledge that the doctor and Buck Denham were their well armed watch, all slept off their weariness soundly and well. There were two little interruptions to their rest, one of which Mark, as he was awakened, knew at once to be the barking roar of a lion far out upon the plain; but he dropped off to sleep directly, and the next one to rouse up suddenly was Dean, who found himself gazing at the doctor standing full in the light cast by the fire, and who at a word from the boy came slowly up to his side. "What is it?" he said. "Well, Dean, I am rather puzzled myself. The cries were those of a drove of some animals, but I don't think they were either hyaenas or jackals. Whatever they were, they were scared by the fire, and--there, you can hear them going farther and farther away among the ruins. I could almost fancy it was a pack of some kind of dogs hunting. There, go back to your blanket. The air's quite cool, and I was glad to come closer to the fire for a warm. Get to sleep again, for I want to explore as much as we can to-morrow. The more I think, the more sure I feel that we have hit upon a very wonderful place, and I am longing for the morning and breakfast, so that we can start for our exploration and see what there is to see." "Do you think we shall be able to go all over the ruins to-morrow, sir?" asked Dean. "No, my boy," said the doctor, laughing; "I certainly do not. There, lie down." As Mark said, it was his nature to, and Dean had no sooner lain down than he dropped off fast asleep, to be roused by his cousin in the pale grey dawn to look at the pigmy seated upon a block of stone just outside the end of the waggon, waiting for the boys to appear, ready to continue his occupation of the previous day and follow both wherever they went. "There he is," said Mark. "I don't know how long he means to stop, but he watches me like a dog. I wish he'd talk, and understand what I say. He can't half take in what Mak says, and Mak's nearly as bad; but somehow they get on together, with a few signs to help, and they are capital friends." "Dan seems quite to put life into us," said Mark, later on. "One feels quite different after a good breakfast. He's been begging me to get the doctor to take him with us as soon as we start to explore." "Well, you don't want any begging," replied Dean. "Oh, no, I shall ask; but Bob Bacon has been at me too, and you saw Buck Denham beckoning to me just now?" "Yes; but he doesn't want to come, does he?"
