The men trained in the science of medicine were those who had a natural aptitude and inclination for the care of the sick—that is, men worthy of being selected to be taught anatomy and the various ailments of the human body. Evidence of this is to be seen in paintings and hieroglyphics found in our Indian caves, which, in due time, it will be my duty to use in photographic illustration in order to correct many erroneous interpretations existing in collections and writings. To return to the beginning of our narrative, Andres Chino Pablo, while deeply pondering one day on the problem of what to give his stricken people, bethought himself suddenly of how in previous years he had treated violent fevers. One was the fever which accompanied pneumonia and which was, at times, fully as dangerous as any fever known to mankind. But it was easily overcome through the administration of compounded herb steam baths. In the course of time “Black Measles” made, by mere accident, its first appearance in the Pacific Southwest, again causing widespread terror among the Indians. However, Chief Andres Lucero had already decided what to do to check the epidemic. Standing calm and cool one morning and facing the rising sun, he called his people to him, everyone, young and old. Like a shaft of granite he stood, straight and erect, his eyes scanning carefully each member of his tribe. At last, with tears in his eyes, showing how deeply moved he was at the woe of his people, he announced his decision. His words were few: “My sons and daughters, as the Great Spirit arises in the East, he comes to help us and he has given me the medicine and the power to cure all those of you who are sick. You will now go to the big cave where you will receive proper care and treatment. All of you shall go, even those who are not suffering from this devil’s disease. And you will all be treated alike so that your blood shall be purified to guard you against the disease.” In other words, to render them “immune,” in our language of today. Now, one of the many caves in the San Jacinto mountain range, one which formerly had been used for religious studies in Chino Canyon, was converted into a cave-hospital and thousands of Indians were treated therein. Due to the supposition, at the time, that the measles, then an unknown malady among the Indians, was really another form of smallpox—the diagnosis made didn’t differ materially from the latter—the conclusion arrived at was to treat the disease accordingly. A tireless and stubborn fight was waged by Chief Andres Lucero. Day and night he labored indefatigably, not only attending to his people, but also instructing other chieftains what to do and what to use, thus letting them share in his success in healing the sick.
