<passage>:
"It is an outrage," said Koltan of the House of Masur, "that the Earthmen land among the Thorabians!" Zotul, youngest of the Masur brothers, stirred uneasily. Personally, he was in favor of the coming of the Earthmen to the world of Zur. nor true Earthmen, but a mixture of both." Zotul sat in silent thought. "But you did not have to buy us out. You had the power to conquer us, even to destroy us. The whole planet could the rank of age, Zotul, who was responsible for affairs of design. "Behold, my sons," said Kalrab, stroking his scanty beard. "What are these Earthmen to worry about? Remember the clay. It is our strength and our fortune. It is the muscle and bone of our trade. Earthmen may but you'll be working for us ... until the children of Earth and Zur are equal in knowledge and therefore equal partners. That's why we had to break down your caste system." "The Thorabians will lick up the gravy," said Singula, whose mind ran rather to matters of financial aspect, "and leave us the grease." By this, he seemed to imply that the Thorabians would rob the Earthmen, "Doubtless," said Zotul unexpectedly, for the youngest at a conference was expected to keep his mouth shut and applaud the decisions of his elders, "the Earthmen used all the metal on their planet in building that ship. We cannot possibly bilk them of it it is their only means Zotul bowed his head meekly, but he burned with resentment. "Listen to the boy," said the aged father. "There is more wisdom in his head than in all the rest of you. Forget the Earthmen and think only of the clay." Zotul did not appreciate his father's approval, for it only earned him did. Still smarting, Zotul went back to his designing quarters and thought about the Earthmen. If it was impossible to hope for much in the way of metal from the Earthmen, what could one get from them? If he could figure this problem out, he might rise somewhat in the estimation of his brothers. That wouldn't take him out of the rank of scapegoat, of too quickly learned the tongue of the aliens hence these left much to be desired in the way of clarity, though their sincerity was evident. The Earthmen were going to do great things for the whole world of Zur. It required but the cooperation—an excellent word, that—of all effect, was what the Earthmen had to say. Zotul felt greatly cheered, for it refuted the attitude of his brothers without earning him a whaling for it. none had succeeded in chiseling them out of it, if, indeed, any had tried. The anti-Earthmen Faction—in any culture complex, there is always an "anti" faction to protest any movement of endeavor—crowed practically acrawl with Earthmen. Immediately, the Earthmen established what they called say!" The pretty young wife laughed at him. "Up to your ears in clay, no wonder you hear nothing of news! The pot is very cheap. The Earthmen "What good is it?" asked Zotul, interested. "How will it hold heat, being so light?" "The Earthmen don't cook as we do," she explained patiently. "There is will have to produce the new stove because all the housewives are buying these pots and there will be a big demand for it. The Earthman "He did, did he? These pots are only a fad. You will soon enough go back to cooking with your old ones." "The Earthman took them in trade—one reason why the new ones are so "Orders already are pouring in like mad," he said the next day. "It was wise of you to foresee it and have the design ready. Already, I am sorry for thinking as I did about the Earthmen. They really intend to do well by us." language—and learned how to read and write. The remainder of the brothers Masur, on the other hand, preferred to remain in ignorance. Moreover, the Earthmen brought miles of copper wire—more than enough in value to buy out the governorship of any country on Zur—and set up telegraph lines from country to country and continent to continent. of the House of Masur continued to look up. "As I have always said from the beginning," chortled Director Koltan, "this coming of the Earthmen had been a great thing for us, and especially for the House of Masur." their appearance on Zur. It became very stylish to eat with the newfangled paraphernalia ... and very cheap, too, because for everything they sold, the Earthmen always took the old ware in trade. What they did with the stuff had been hard to believe at first. They destroyed it, which proved how valueless it really was. senile stupor for the occasion, on the off chance that the old man might still have a little wit left that could be helpful. "Note," Koltan announced in a shaky voice, "that the Earthmen undermine nowhere with their wrangle, he cleared his throat and spoke up. "My sons, you forget it is not the Earthmen themselves at the bottom of your trouble, but the things of Earth. Think of the telegraph and the newspaper, how these spread news of every shipment from Earth. The merchandise of the Earthmen is put up for sale by means of these newspapers, which also are the property of the Earthmen. The people are intrigued by these advertisements, as they are called, and flock to from the House of Masur all available space was occupied by the advertisements of the Earthmen. In their dozenth conference since that first and fateful one, the "Some new devilment of the Earthmen, you can be sure," said Koltan blackly. In fact, the Earthmen were building an assembly plant for radio Earthmen are taking care of that." At any rate, the brothers Masur were still able to console themselves Broderick told him. "It may seem high," said the Earthman, "but remember that Earth is "Impossible," said Zotul drably. "Not I and all my brothers together have so much money any more." "You don't know us of Earth very well yet, but you will. I offer you 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. 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 The Pottery of Masur had no more contracts. Business languished. The Earthmen, explained Broderick, had built a plant of their own because it was so much more efficient—and to lower prices, which was Earth's unswerving policy, greater and greater efficiency was demanded. Broderick was very sympathetic, but there was nothing he could do. 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. was remarkable that he paid so little attention, for the female terrestrials were picked for physical assets that made Zurian men covetous and Zurian women envious. Zotul stared blankly. This was not the governor. This was Broderick, the Earthman. Broderick nodded agreeably. "I am the governor and I am well acquainted with your case, Mr. Masur. Shall we talk it over? Please sit down." "I don't understand. The Earthmen...." Zotul paused, coloring. "We are not pay for the roads, the telegraphs, the civic improvements, we took them over, just as we are taking you over." "You mean," exclaimed Zotul, aghast, "that you Earthmen own everything on Zur?"
