The two auto-loading rifles began to crack. After the first few shots, the savages took cover. Evidently they understood the capabilities and limitations of the villagers' flintlocks, but this was a terrifying surprise to them. "Jim!"--Altamont was almost praying into the radio--"Come in, Jim!" "What is it, Monty? I was outside." Altamont told him. "Those fellows you had up with you yesterday, think they could be trusted to handle the guns? A couple of them are here with me," Loudons inquired. "Take a chance on it! It won't cost anything but my life, and that's not worth much at the present." "All right, hold on. We'll be there in a few minutes." "Loudons is bringing the helicopter," Altamont told the others. "All we have to do is to hold on, here, until he comes." A naked savage raised his head from behind what might, two hundred years ago, have been a cement park-bench and he was only a hundred yards away. Reader Rawson promptly killed him and began reloading. "I think you're right, Tenant," he said. "The Scowrers have never attacked in bands like this before. They must have a powerful reason and I can think of only one." "That's what I'm beginning to think, too," Verner Hughes agreed. "At least, we've eliminated the third of your possibilities, Tenant. And I think probably the second, as well." Altamont wondered what they were double-talking about. There wasn't any particular mystery about the mass attack of the wild men to him. Debased as they were, they still possessed speech and the ability to transmit experiences. No matter how beclouded in superstition, they still remembered that aircraft dropped bombs, and bombs killed people, and where people had been killed, they would find fresh meat. They had seen the helicopter circling about, and had heard the blasting: everyone in the area had been drawn to the scene as soon as Loudons had gone down the river. But they seemed to have forgotten that aircraft carried guns, although they did spring to their feet and start to run at the return of the helicopter. However, most of them did not run far. IX Altamont and Loudons shook hands many times in front of the Aitch-Cue House, and listened to many good wishes, and repeated their promise to return. Most of the microfilmed books were to be stored in the old church. They were taking with them only the catalogue and a few of the most important works. Finally, they entered the helicopter. The crowd shouted farewell as they rose. Altamont, at the controls, waited until they had gained five thousand feet, then turned on a compass-course for Colony Three. "I can't wait until we're in radio range of the Fort, Jim. This is one report that I really want to make," he said. "Of all the wonderful luck!" he went on. "And I don't know which is the more important: finding those books, or finding those people. In a few years, when we can get them supplied with modern equipment and instructed in its use--
