“We’ll try artificial respiration,” said Merriwell. “You work his lungs while I work his arms.” What followed caused the wildest excitement among the watching Arabs, for Buckhart knelt astride the body of the old sheik and began a regular and steady pumplike movement on the lower part of his breast, while Dick seized the man’s arms, pulled them at full length above the Arab’s head, then bent them back suddenly and pressed them to his sides. The two boys worked together in perfect unison. Some of the Arabs cried out that the infidels were defiling the dead. Two or three of them drew weapons and would have rushed on the boys; but the same husky fellow, who had checked them before now, produced a pistol and averred that he would “blow daylight” through the whole of them if they did not keep still. In this manner they were temporarily checked, and that brief check gave Merriwell time enough to accomplish his purpose. A low moan and a convulsive gasp came from the lips of the man over which the boys were working. Signs of returning consciousness were pronounced. His breast heaved. The boys ceased their work. For he breathed. An Englishman held out a flask of whisky. “Give him a swallow of this,” he advised. Dick pushed it away. “Water,” he called. “That will be better for him.” “Allah! Allah!” cried the astounded Arabs. “The infidels are magicians! They have restored the dead to life! Ras al Had lives again!” Some of them prostrated themselves in the dust. Others hastened to bring water. Dick took a canteen and turned a little of the liquid between the lips of the injured man. He swallowed it greedily, coughed a little, and then lay gazing in a puzzled manner at the face of the American boy. Finally, in very good English, he asked what had happened. His voice was weak and husky, yet his words were plain. “You were struck by the train,” explained Merriwell. “Your camel was killed, and you seemed to be dead; but I think you are all right now.” “For which you may thank this boy and his friend here,” said the husky chap, who had protected the boys. “To all appearances, you were as dead as old Mohammed; but they pumped the breath back into you in a hurry.” Several of the Arabs now brought cushions, which were placed beneath the head and shoulders of the sheik. One of them spoke to him hurriedly in a low tone, and seemed telling him all about what had taken place. When this man had finished speaking the sheik made a gesture with his hand and bade him retire. He then called for Dick. “Be careful, Richard,” cautioned Professor Gunn. “These men are treacherous. There’s no telling what he means to do.” Dick laughed and stepped nearer to the sheik. “Boy,” said the old Arab, “they tell me that I was dead, and by your infidel magic you brought life back into my body.” “You were unconscious, that was all. The shock had driven the breath from your body, and we simply revived the action of your lungs.” “Had you not done so——”
