Dolo Anah went on. "And observe this." He dug into the ground before him and revealed the crystal ball that had magically appeared before. He showed to them the little elevator device beneath it which he manipulated with a small rubber bulb which pumped air underneath. One or two of them ventured a scornful laugh, at the obviousness of the trick. Dolo Anah took up the ball and unscrewed the base. Inside were a delicate arrangement of film on a continuous spool so that the scene played over and over again, and a combination of batteries and bulbs to project the scene on the ball's surface. He explained, in patient detail, the workings of the supposed magic ball. Two of the boys had seen movies on trips to Mopti, the others had heard of them. Finally one, highly encouraged now, as were the others, said, "But why do you show us this and shame us for our foolishness?" Dolo Anah nodded encouragement at the teen-ager. "I do not shame you, my son, but your fathers and the Hogons and the so-called witchmen. For long ages the Dogon have been led by the oldest members of the tribe, the Hogons. This can be nonsense because in spite of your traditions age does not necessarily bring wisdom. In fact, senility as it is called can bring childish nonsense. A people should be governed by the wisest and best among them, not by tradition, by often silly beliefs handed down from one generation to another." Hinnan, who was eldest son of the head chief, said, "But why do you tell us this, after shaming our fathers and the old men of the Dogon?" For the first time since the elders had left, Dolo Anah's eyes gleamed as before. "Because you will be the leaders of the Dogon tomorrow, most like. And it is necessary to learn these great truths. That you attend the schools and bring to the Dogon tomorrow what they did not have yesterday, and do not have today." "But suppose we tell them of how you have deceived them?" the other articulate Dogon lad said. Dolo Anah chuckled and shook his head. "They will not believe you, boy. They will be afraid to believe you. And besides, men are almost everywhere the same. It is difficult for an older man to learn from a younger one, especially his own son. It is vanity, but it is true." His mouth twisted in memory. "When I was a lad myself, on the beaches of an island far from here in the Bahamas, my father beat me on more than one occasion, indignant that I should wish to attend the white man's schools, while he and his father before him had been fishermen. Beneath his indignation was the fear that one day I would excel him." "You are right," Hinnan said uncomfortably, "they would not believe us." Instinctively, the son of the head chief assumed leadership of the others. "We will keep this secret between us," he said to them. Dolo Anah came to his feet, yawned, stretched his legs and began to pack his gadgets into the small valise he carried. "Good luck, boys," he said unthinkingly in English.
