Yet the big fellow actually was sinking with weariness. The fearful hardships that he had undergone had worked havoc with him. Now that the agonizing nerve-strain was lifted he was going to pieces. He stood wavering for a minute, then he slowly sat down in the sand. Rhoda stood beside him uncertainly and looked from the man to the immovably distant mountain peak. She realized that, in stopping, the risk of recapture was great, yet her desert experiences told her that John must regain some of his strength before the sun caught them. She had little faith that they would tumble upon the camp as easily as John thought, and wanted to prepare for a day of desert heat. "If we were sure just where the camp lay," she said, "I would go on for help. But as we aren't certain, I'm afraid to be separated from you, John." John looked up fiercely with his haggard eyes. "Don't you dare to move six inches from me, Rhoda. It will kill me to lose you now." "Of course I won't," said Rhoda. "I've had my lesson about losing myself in the desert. But you must have some sleep before we go any farther." Rhoda spoke with a cheerfulness she did not feel. She looked about for a comfortable resting-place but the desert was barren. "There's no use trying to find a comfortable bed," she said. "You had better lie down right where you are." "Honey," said John, "I've no idea of sleeping. It will be time enough for that when we reach camp. But if you think you could stand guard for just ten minutes I will lie flat in the sand and rest. You take my watch and time me." "That's splendid!" said Rhoda, helping him to clear of rocks and cactus a space long enough to lie in. "Just ten minutes," said DeWitt, and as he spoke he sank to sleep. Rhoda stood in the moonlight looking into the man's unconscious face. His new-grown beard gave him a haggard look that was enhanced by the dark circles under his eyes. That wan face touched Rhoda much more than the healthy face of former days. The lines of weariness and pain that never could be fully erased were all for her, she thought with a little catch of her breath. Then with a pitying, affectionate look at the sleeping man came a whimsical smile. Once she had thought no one could equal John in physical vigor. Now she pictured Kut-le's panther strength and endurance, and smiled.
