He put the query slyly, wording it as if it were a matter of general interest only, and of no great importance. Were they familiar with machines that killed, and if so, what varieties did they have? At first Mark did not understand the question. He replied that their machines did not kill, that very long ago they had done so but that the machines were much better now, very safe and not harmful to anyone. "Then," wrote Weaver carefully, "you have no machines which are made for the purpose of killing?" Mark, Luke and John discussed this with every evidence of excitement. At last Mark wrote, "This very new idea to us." "But do you have in this world no large, dangerous animals which must be killed? How do you kill those things which you eat?" "No dangerous animals. We kill food things, but not use machines. Give some things food which make them die. Give some no food, so they die. Kill some with heat. Some eat alive." Weaver winced with distaste when he read this last, and was about to write, "This must stop." But he thought of oysters, and decided to reserve judgment. After all, it had been foolish of him to be frightened last night. He had been carried away by a chance comparison which, calmly considered, was superficial and absurd. These people were utterly peaceful--in fact, spineless. He wrote, "Take the aircar up farther, so that I can see this village from above." He signaled John to stop when they had reached a height of a few hundred feet. From this elevation, he could see the village spread out beneath him like an architect's model--the neat cross-hatching of narrow streets separating the hollow curves of rooftops, dotted with the myriad captive balloons launched in honor of his appearance. The village lay in the gentle hollow of a wide valley, surrounded by the equally gentle slopes of hills. To his right, it followed the bank of a fair-sized river; in the other three directions the checkered pattern ended in a careless, irregular outline and was replaced by the larger pattern of cultivated fields. It was a good site--the river for power, sanitation and transportation, the hills for a sheltered climate. He saw suddenly, in complete, sharp detail, how it would be. "The trip is over," he wrote with sudden decision. "We will stay here, and build a city." III The most difficult part was the number of things that he had to learn. There was no trouble about anything he wanted done by others; he simply commanded, and that was the end of it. But the mass of knowledge about the Terranovans and their world before he came appalled him not only by its sheer bulk but by its intricacy, the unexplained gaps, the contradictions. For a long time after the founding of New Washington--later New Jerusalem--he was still bothered a little by doubt. He wanted to learn all that there was to learn about the Terranovans, so that finally he would understand them completely and the doubt would be gone.
