"We're in a much better position than the metropolitan areas," said Professor Maddox. "I think we'll manage if we can keep our people from getting panicky. It's easier, too, because there aren't so many of us." Professor Larsen went back to the laboratory with the Maddoxes. Throughout the night they reviewed the work of Dr. French. To Ken it seemed that they were using material out of the past, since all of those responsible for it were probably dead. "We'll have to fill in these missing steps," said Professor Maddox. "We know what he started with and we know the end results at which he was aiming. I think we can fill the gaps." "I agree," said Professor Larsen. "I think we should not neglect to pass this to our people in Stockholm. You will see that is done?" he asked Ken. "Our next schedule in that area is day after tomorrow. Or I could get it to them on the emergency watch tomorrow afternoon." "Use emergency measures. I think it is of utmost importance that they have this quickly." * * * * * As the days passed, strangers were appearing more and more frequently in Mayfield. Ken saw them on the streets as he went to the warehouse for his family's food ration. He did not know everyone who lived in the valley, of course, but he was sure some of the people he was meeting now were total strangers, and there seemed so many of them. He had heard stories of how some of them had come, one by one, or in small groups of a family or two. They had made their way from cities to the north or the south, along the highway that passed through the valley. They had come in rags, half-starved, out of the blizzards to the unexpected sanctuary of a town that still retained a vestige of civilization. Unexpectedly, Ken found this very subject was being discussed in the ration lines when he reached the warehouse. People had in their hands copies of the twice-weekly mimeographed newssheet put out by the Council. Across the top in capital letters was the word: PROCLAMATION. Ken borrowed a sheet and read, "According to the latest count we've made through the ration roll, there are now present in Mayfield almost three thousand people who are refugees from other areas and have come in since the beginning of the disaster. "As great as our humanitarian feelings are, and although we should like to be able to relieve the suffering of the whole world, if it were in our power to do so, it is obviously impossible. Our food supplies are at mere subsistence level now. Before next season's crops are in, it may be necessary to reduce them still further. "In view of this fact, the Mayor and the City Council have determined to issue a proclamation as of this date that every citizen of Mayfield will be registered and numbered and no rations will be issued except by proper identification and number. It is hereby ordered that no one hereafter shall permit the entrance of any stranger who was not a resident of Mayfield prior to this date.
