 The guide led him to the home of the "jefe" of Casas Grandes, and there Hewett saw Schlatter's Bible, saddle, and copper rod—which had become a mysterious hallmark of the healer from the time of his disappearance.Years later, in 1922, Hewett returned to Mexico and examined the copper rod again.By now the director of the School of American Research (now the School for Advanced Research) and the Museum of New Mexico, he showed interest in the rod and made a donation to the village of Casas Grandes to hire a teacher.
