"If we took a spectrograph of the comet and found this same line strongly present, we would have a good case for proving the comet was the source of this substance."
"Let's have a try," said Vickers. "I don't know how successfully we can get a spectrograph of the comet, but it's worth an attempt."
Their time was short, before the comet vanished below the horizon for the night. They called for help from the other boys and moved the equipment to the roof, using the small, portable 6-inch telescope belonging to the physics department.
There was time for only one exposure. After the sun had set, and the comet had dropped below the horizon, they came out of the darkroom and placed the prints in the viewing instrument.
Vickers moved the adjustments gently. After a time he looked up at the circle of boys. "You were right, Ken," he said. "Your hunch was right. The comet is responsible. Our engines have been stopped by dust from the stars."
Chapter 8.
Attack
There are people who feed upon disaster and grow in their own particular direction as they would never have grown without it, as does the queen bee who becomes queen only because of the special food prepared by the workers for her private use.
Such a man was Henry Maddox. He would not have admitted it, nor was he ever able to realize it, for it violated the very principles he had laid down for Ken. But for him, the comet was like a sudden burst of purpose in his life. He had taught well in his career as professor of chemistry at the State Agricultural College at Mayfield, but it had become fairly mechanical. He was vaguely aware of straining at the chains of routine from time to time, but he had always forced himself through sheer exercise of will to attend to his duties. There was never time, however, for any of the research he used to tell himself, in his younger days, he was going to do.
With the sudden thrusting aside of all customary duties, and with the impact of catastrophe demanding a solution to a research problem, he came alive without knowing what was happening. Yet without the imminence of disaster he would not have found the strength to drive himself so. This was what he could not admit to himself.
