Pottery of Masur, even though nobody listened to him any more and are equal in knowledge and therefore equal partners. That's why we had to break down your caste system." Zotul's eyes widened. "And that is why my brothers did not beat me when I failed!" fame and fortune of the House of Masur." Zotul did not appreciate his father's approval, for it only earned him a beating as soon as the old man went to bed. It was a common enough thing among the brothers Masur, as among everybody, to be frustrated in their desires. However, they had Zotul to take it out upon, and they did. his brothers. That wouldn't take him out of the rank of scapegoat, of course, but the beatings might become fewer and less severe. for it refuted the attitude of his brothers without earning him a whaling for it. There was also some talk going around about agreements made between them." After he had beaten his wife thoroughly for her foolishness, Zotul The kilns of the Pottery of Masur fired day and night to keep up with million had been made and sold by the Masurs alone, not counting the brothers Masur, on the other hand, preferred to remain in ignorance. especially for the House of Masur." What they did with the stuff had been hard to believe at first. They destroyed it, which proved how valueless it really was. The result of the new flood was that in the following year, the sale of Masur ceramic table service dropped to less than a tenth. sells it, of course, but before the people get the shine out of their eyes, we can be ruined." The brothers discussed the situation for an hour, and all the while from the House of Masur brothers Masur decided upon drastic steps. In the meantime, several gas-fired ranges, furnaces and heaters ... and the Masur stove business at a nice profit and everybody was happy with the situation except the brothers Masur. The drastic steps of the brothers applied, therefore, to making an energetic protest to the governor of Lor. natural follow-up in its campaign of advertising—radio programs—with commercials. Happily for the brothers, they did not understand this at the time or they would surely have gone back to be buried in their own clay. Earthmen are taking care of that." At any rate, the brothers Masur were still able to console themselves The demand for Masur tile hit rock bottom. The next time the brothers went to see the governor, he said, "I cannot All the brothers could no longer be spared from the plant, even for the purpose of pressing a complaint. Their days of idle wealth over, they had to get in and work with the clay with the rest of the help. with something called "blacktop" and jammed with an array of glittering new automobiles. An automobile was an expense none of the brothers could afford, now that they barely eked a living from the pottery. Still, Zotul ached with desire at sight of so many shiny cars. Only a few had them and made upon the business of the Pottery of Masur. "Once," he said formally, "the Masur fortune was the greatest in Masur—Divinity protect him—departed this life to collect his greater bones of our culture and our fortune. Now it has been shown how prone is the flesh to corruption and how feeble the bones. We are ruined, and the music," he explained. "I cannot afford the other things." Broderick clucked sympathetically. One who could not afford the merchandise. All you pay is the freight, which is cheap, considering the cost of operating an interstellar spaceship." "Impossible," said Zotul drably. "Not I and all my brothers together have so much money any more." involutions and devolutions of credit, leaving out some angles that might have had a discouraging effect. "Just sign this paper," said Broderick, "and you become part of our Easy Payment Plan." Zotul drew back. "I have five brothers. If I took all these things for myself and nothing for them, they would beat me black and blue." "Here." Broderick handed him a sheaf of chattel mortgages. "Have each of your brothers sign one of these, then bring them back to me. That is all there is to it." It sounded wonderful. But how would the brothers take it? Zotul wrestled with his misgivings and the misgivings won. "I will talk it over with them," he said. "Give me the total so I will have the figures." The total was more than it ought to be by simple addition. Zotul pointed this out politely. "Interest," Broderick explained. "A mere fifteen per cent. After all, you get the merchandise free. The transportation company has to be paid, so another company loans you the money to pay for the freight. This small extra sum pays the lending company for its trouble." "I see." Zotul puzzled over it sadly. "It is too much," he said. "Our plant doesn't make enough money for us to meet the payments." company." Zotul, anxious to possess the treasures promised by the Earthman, won over his brothers. They signed with marks and gave up a quarter interest in the Pottery of Masur. They rolled in the luxuries of Earth. These, who had never known debt before, were in it up to their ears. The retooled plant forged ahead and profits began to look up, but the Earthmen took a fourth of them as their share in the industry. For a year, the brothers drove their shiny new cars about on the new concrete highways the Earthmen had built. From pumps owned by a batteries for the radios were no longer available and everybody had to buy the new radios. And who could do without a radio in this modern age? The homes of the brothers Masur blossomed on the Easy Payment Plan. They had refrigerators, washers, driers, toasters, grills, electric fans, air-conditioning equipment and everything else Earth could possibly sell them. "We will be forty years paying it all off," exulted Zotul, "but meantime we have the things and aren't they worth it?" But at the end of three years, the Earthmen dropped their option. The Pottery of Masur had no more contracts. Business languished. The slow, but it was extremely sure. The brothers Masur got along in spite of dropped options. They had less money and felt the pinch of their debts more keenly, but television kept their wives and children amused and furnished an anodyne for the pangs of impoverishment. The pottery income dropped to an impossible low, no matter how Zotul designed and the brothers produced. Their figurines and religious ikons were a drug on the market. The Earthmen made them of plastic and sold them for less. The brothers, unable to meet the Payments that were not so Easy any more, looked up Zotul and cuffed him around reproachfully. "You got us into this," they said, emphasizing their bitterness with fists. "Go see Broderick. Tell him we are undone and must have some of toughness about the set of his jaw and the hardness of his glance. "So you can't pay," he said, tapping his teeth with a pencil. He "If we have to sue, we take back the merchandise and everything attached to them. That means you would lose your houses, for they are will only require you to assign the remaining three-quarters of your pottery to us." The brothers, when they heard of this, were too stunned to think of beating Zotul, by which he assumed he had progressed a little and was somewhat comforted. "To fail," said Koltan soberly, "is not a Masur attribute. Go to the Masur has long supported the government with heavy taxes. Now it is from you. That is true. Since the House of Masur was the largest and richest on Zur, it has taken a long time—the longest of all, in fact." bought you out." "Our government...." "Your governments belong to us, too," said Broderick. "When they could not pay for the roads, the telegraphs, the civic improvements, we took them over, just as we are taking you over."
