On the following day, John Clayton was astounded to hear from Esther that she would not return as she had half promised to do in the fall. But Esther offered no explanations; and Kenneth's calls, from that day, grew less frequent. So the days passed, and two lives drifted apart. CHAPTER XXI THE VALLEY OF THE SHADOW At the close of the religious service, the following day, Esther learned of many cases of sickness, in and about Gila, and especially along the water courses. A sort of a fever, the people told her. She resolved to make neighborhood calls the following day, and to take with her a case of medicine. She found many people sick with what seemed to be the same malady; and, thereupon, began a thorough investigation. The result was that she persuaded the people to let her call a physician. On the following day, Dr. Mishell drove into camp, and Esther made the rounds with him. As she suspected, the malady proved to be typhoid fever. "These people must have intelligent care," the physician said gruffly to her. "Do you know anything about nursing?" She told him she had nursed two patients through typhoid fever. "You know how to take respiration and temperature, then?" he said brusquely. She assured him she did. Then he wrote out directions for each patient, especially noting what to do, if certain conditions should arise. "You know the importance of sponging patients?" he asked shortly. "Yes." "Any alcohol?" "I can get it." And so Esther Bright was installed head nurse in Gila. Helpers rallied to her aid. School was dismissed at an early hour each day, so that Esther could make the rounds daily. The heat grew almost intolerable, but the delicate girl went on her way as if made of iron. Dr. Mishell looked her over with a nod of approval. "A woman of sense," he said, in speaking of her to Kenneth Hastings. The physician came again in three days, only to find many new cases. Esther Bright's task was becoming enormous. "Can you do it?" the physician had asked. And quietly she had answered: "I can do it as long as anyone needs my care." Again the physician nodded approvingly, and muttered: "Some women do have some sense." When this second visit drew to a close, he looked sharply at Esther, and said in a crusty tone: "You are working too hard." She protested. "I say you _are_!" he reiterated. "I'm going to find someone to come help you. Mr. Clayton wishes it. Are you a Catholic?" "No, a Quaker." "Quaker! Quaker!" he repeated. "No objections to a Catholic, I suppose?" "No objections to any human being who serves humanity." The old man left her abruptly. As he untied his horse, preparatory to leaving, he muttered to himself: "A very unusual woman. A _very_ unusual woman!"
