complete rounds of the cave, sniffing at every crack and crevice, he came to each of the watching men, nosing them carefully. Then he walked directly to the side of the unconscious Nu, licked his cheek, and lying down beside him rested his head upon the man's breast so that his fierce, wolfish eyes were pointed straight and watchful at the group of men opposite him. "There," said Barney, leaning down and stroking the beast's head. The hound whined up into his face; but when Curtiss approached he rose, bristling, and standing across the body of Nu growled ominously at him. "You'd better keep away from him, Curtiss," warned Brown. "He always has had a strange way with him in his likes and dislikes, and he's a mighty ugly customer to deal with when he's crossed. He's killed one man already—a big Wamboli spearman who was stalking Greystoke up in the north country last fall.

"Nu does not understand the stranger's tongue," he said. And then he asked the same question as had Barney: "Where is Nat-ul?" But the American could translate only the name, yet it told him that here indeed was the dream-man of his sister. When it became quite evident that the man could not understand anything that they said to him, and that he was in no condition to march, it was decided to send him back to the ranch by some of the native carriers that accompanied the searching party, while the others continued the search for the missing girl. Terkoz suffered them to lift Nu in their arms and carry him outside where he was transferred to a rude litter constructed
