"“We have few Scandinavian arrivals, and none of such appearance as this,” said Winston. “How many are there?” “Well, sir, when we first noticed them there were seven, and they hadn't been there a moment before.” “Seven? You're crazy. There are hundreds.” “Yes, sir. I'm crazy. A minute after there were seven, there were seventeen. But no more had come from anywhere. Then there were sixty. We separated them into groups of ten and watched them very closely. None crossed from one group to another, none came from anywhere else. But soon there were fifteen, then twenty-five, then thirty in each group."  —R. A. Lafferty
