The conversation paused long enough for a few bites of lunch, then Bartouki resumed. "We try to take good care of tourists in the United Arab Republic, both in Egypt and in Syria. For example, we license our guide-interpreters, who are called _dragomen_. There is also a special police force with no job but aid to tourists. And we are always looking for ways to improve our reproductions to make them more attractive and authentic. I will show you a new design." By the time luncheon had ended, the talk among the scientists had progressed to the basic theory of what physicists call "the solid state." Even Rick, with his rapidly growing background of scientific knowledge, could understand only fragments of conversation. "Let them talk over their coffee," Bartouki said. "They are enjoying it. We will retire to my den and I will show you examples from El Mouski." The samples were everything Bartouki had promised. There were wall hangings, beautifully made of tiny pieces of colored cloth appliqued on a natural-color fabric, bags and pouches of leather, leather hassocks, ivory carvings of ancient Egyptian gods, inlaid boxes and chests, and dozens of both useful and ornamental utensils of brass, copper, washed tin, and ceramics. Barby went into raptures. At every new item she urged Rick to bring her one just like it. "I'll rent a jet just to carry my luggage," he said, grinning. "You've already ordered a ton, and I get only sixty-six pounds." Bartouki came to his rescue. "Let me show you a new tourist attraction. It just arrived by messenger this morning." He went to a cabinet, opened it, and produced a stone cat. It was about ten inches high, in a sitting position with its tail curled around to meet its feet. It was of sandy texture, reddish in color. "Sandstone?" Rick guessed. Bartouki smiled. "I hoped you would say that. Here. Examine it." Rick took the cat. He liked it very much. The design was clean and elegant, stylized after the Egyptian manner. But it wasn't sandstone. It was heavy, but not heavy enough to be sandstone, and the sheen was not that of a mineral. Whatever the material, it had been fashioned in one piece, probably cast in a mold. "I give up," he said. "What is it?" "Plastic," Bartouki replied, obviously pleased. "It did not come from Egypt. It was made right here in America. In Chicago, to be exact. It is what you call a prototype." "But it's Egyptian in design," Barby protested. She took the cat from Rick and examined it. "Yes, it is clearly an Egyptian cat. The design came from Egypt, but the cat from America. I have been working on this for months with a plastics company. Now I have the model, and the method. We will reproduce these in quantity in Cairo." "It's pretty heavy for plastic," Rick commented.
