The troops came into sight. Rick lost altitude and began a slow circle only a few hundred feet over the marching soldiers. He turned on the switches and nodded. The governor began to talk in slow, clear Spanish. Rick understood that he identified himself to the men below, but then he lost the trend of the talk. He concentrated on flying. The loud-speakers were operating perfectly, and he knew the troops could hear. He could see them looking up and pointing, but they kept marching. Apparently the governor wasn't making much of an impact. The governor paused, and Rick cut the switches. "Maybe they don't believe it's you," he suggested. "Perhaps not. But my voice is well known. I speak over the radio at least once a week. More likely the whole idea is just too much for them. Who can believe that mountain over there is about to blow up?" "Let's try the troops at the pumice works. Maybe you can tell them that all who care about their homeland should march at once to Calor." "I'll try it," the governor agreed. Rick circled low over the pumice works while the loud-speakers blasted at the troops below. They watched the plane, they pointed, some ran out for a better look. But when the governor pleaded with them to hurry to Calor to help save the people of the island, nothing happened. "If El Viejo started smoking, they'd move fast enough," Rick said bitterly. "But then it would be too late. They just don't believe there is any danger, and maybe they're not sure it's you. I guess no one has ever given them orders from the air before." "They are simple people," the governor agreed. "I think most of them have never heard of a volcano. They don't even know what an eruption is. How can they be excited? If I ever succeed in getting good schools here, this may change. But it won't help us now." Rick considered. It would do little good to repeat the announcement to the soldiers at the hotel. He wondered if Guevara and Connel were somewhere below, and with that thought he turned toward the diamond pipe. "Let's see if we can do any good with the truckmen," he suggested. "Tell them the trucks are essential to the safety of their families." The governor tried, while Rick held the plane in in a tight circle over the blue ground. Again, there was interest in the flying loud-speaker plane itself, but the message made no impact. Then Rick noticed tiny spurts of fire from one edge of the diamond field and cold sweat started on his forehead as he suddenly realized what they were. "They're shooting at us!" he exclaimed, and gave the plane the gun, taking evasive action as the distance widened. [Illustration: _"They're shooting at us!" Rick exclaimed, and gave the plane the gun_] "I saw," the governor said wearily. "It was not the troops. It was the peons. Our friend Guevara is down there, I think. But he need not be afraid of our effect. We have had none."
