Art Matthews came around later that same day. "You look worse than one of these engines that's got itself full of stardust," he said. "You must have been off your rocker, prowling around back alleys in the middle of the night!"

Ken grinned. "Hi, Art. I knew you'd be full of sympathy. What's going on outside while I've been laid up? Say—I don't even know how long I've been here! What day is it?"

"Tuesday. Not that it makes any difference any more."

"Tuesday—and it was Saturday when I was working with the spectroscope. I've been here three days!"

"A week and three days," said Art Matthews. "You were out cold for three days straight, and they wondered if your bearings were ever going to turn again."

Ken lay back in astonishment. "Nobody's told me anything. What's happening outside?"

"It's going to be a rough winter," Art Matthews said, grimly. "Snow's started heavy, two weeks earlier than usual. I understand Professor Douglas thinks it's got something to do with the comet dust in the air."

"That figures. What about the fuel supply?"

"In pretty sad shape, too. So far, the stockpile is big enough for about a week and a half of real cold. They laid off woodcutting for three days to spend all the time converting oil burners, and making new heaters out of 50-gallon barrels and anything else they could find. It's going to be a mighty cold winter—and a hungry one."
