From the vantage point of the walkingway far above, Lieutenant Hines scanned the landscape in all directions through powerful glasses as he had done for so long that it seemed he knew every shrub and tree and blade of grass within sight. The wild life of savage Pellucidar that crossed and re-crossed the clearing had long since become an old story to these three men. Again and again as one animal or another had emerged from the distant forest the glasses had been leveled upon it until it could be identified as other than man; but now Hines voiced a sudden, nervous exclamation. "What is it?" demanded Zuppner. "What do you see?" "It's a man!" exclaimed Hines. "I'm sure of it." "Where?" asked Dorf, as he and Zuppner raised their glasses to their eyes. "About two points to port." "I see it," said Dorf. "It's either Gridley or Von Horst, and whoever it is he is alone." "Take ten of the crew at once, Lieutenant," said Zuppner, turning to Dorf. "See that they are well armed and go out and meet him. Lose no time," he shouted after the Lieutenant, who had already started down the climbing shaft. The two officers upon the top of the O-220 watched Dorf and his party as it set out to meet the man they could see trudging steadily toward the ship. They watched them as they approached one another, though, owing to the contour of the land, which was rolling, neither Dorf nor the man he had gone to meet caught sight of one another until they were less than a hundred yards apart. It was then that the Lieutenant recognized the other as Jason Gridley. As they hastened forward and clasped hands it was typical of the man that Gridley's first words were an inquiry relative to the missing members of the party. Dorf shook his head. "You are the only one that has returned," he said. The eager light died out of Gridley's eyes and he suddenly looked very tired and much older as he greeted the engineers and mechanics who made up the party that had come to escort him back to the ship. "I have been within sight of the ship for a long time," he said. "How long, I do not know. I broke my watch back in the forest a way trying to beat a tiger up a tree. Then another one treed me just on the edge of the clearing in plain view of the ship. It seems as though I have been there a week. How long have I been gone, Dorf?" "About seventy-two hours." Gridley's face brightened. "Then there is no reason to give up hope yet for the others," he said. "I honestly thought I had been gone a week. I have slept several times, I never could tell how long; and then I have gone for what seemed long periods without sleep because I became very tired and excessively hungry and thirsty." During the return march to the ship Jason insisted upon hearing a detailed account of everything that had happened since his departure, but it was not until they had joined Zuppner and Hines that he narrated the adventures that had befallen him and his companions during their ill-fated expedition.
