It was not long before he picked up a few words which he had heard his employers using, and related them to the things or acts spoken of. And he began to notice that these people, in spite of the crudities of their own life, enjoyed some of the advantages of a fairly complex civilization. Their implements were not hand-craft products, but showed machine workmanship. There were two objects hanging on hooks on the kitchen wall which he was sure were weapons. Both had wooden shoulder-stocks, and wooden fore-pieces; they had long tubes extending to the front, and triggers like blasters. One had double tubes mounted side-by-side, and double triggers; the other had an octagonal tube mounted over a round tube, and a loop extension on the trigger-guard. Then, there was a box on the kitchen wall, with a mouthpiece and a cylindrical tube on a cord. Sometimes a bell would ring out of the box, and the woman would go to this instrument, take down the tube and hold it to her ear, and talk into the mouthpiece. There was another box from which voices would issue, of people conversing, or of orators, or of singing, and sometimes instrumental music. None of these were objects made by savages; these people probably traded with some fairly high civilization. They were not illiterate; he found printed matter, indicating the use of some phonetic alphabet, and paper pamphlets containing printed reproductions of photographs as well as verbal text. There was also a vehicle on the farm, powered, like the one he had seen on the road, by an engine in which a hydrocarbon liquid-fuel was exploded. He made it his business to examine this minutely, and to study its construction and operation until he was thoroughly familiar with it. It was not until the third day after his arrival that the chickens began to die. In the morning, Hradzka found three of them dead when he went to feed them, the rest drooping unhealthily; he summoned the man and showed him what he had found. The next morning, they were all dead, and the cow was sick. She gave bloody milk, that evening, and the next morning she lay in her stall and would not get up. The man and the woman were also beginning to sicken, though both of them tried to continue their work. It was the woman who first noticed that the plants around the farmhouse were withering and turning yellow. * * * * *
