The dogs were being harnessed next morning when the two men hopped into the plane. The thermometer was unusually high for the season, for in the south polar regions the short summer is usually at an end by March. Tommy was sweating in his furs in a temperature well above the freezing point. The snow was crusted hard, the sky overcast with clouds, and a wind was blowing hard out of the south, and increasing in velocity hourly.
"A bad day for starting," said Captain Storm. "Looks like one of the autumn storms was blowing up. If I were you, I'd watch the weather, Tommy."
Tommy glanced at Dodd, who was huddled in the rear cockpit, fuming at the delay, and grinned whimsically. "I guess I can handle her, Captain," he answered. "It's only an hour's flight to where he found that fossil."
"Just as you please," said Storm curtly. He knew that Tommy's judgment as a pilot could always be relied upon. "You'll find us here when you return," he added. "I've counter-manded the order to march. I don't like the look of the weather at all."
Tommy grinned again and pressed the starter. The engine caught and warmed up. One of the men kicked away the blocks of ice that had been placed under the skids to serve as chocks. The plane taxied over the crusted snow, and took off into the south.
The camp was situated in a hollow among the ice-mountains that rose to a height of two or three thousand feet all around. Tommy had not dreamed how strongly the gale was blowing until he was over the top of them. Then he realized that he was facing a tougher proposition than he had calculated on. The storm struck the biplane with full force.
A snowstorm was driving up rapidly, blackening the sky. The sun, which only appeared for a brief interval every day, was practically touching the horizon as it rose to make its minute arc in the sky. A star was visible through a rift in the clouds overhead, and the pale daylight in which they had started had already become twilight.
Tommy was tempted to turn back, but it was only a hundred miles, and Jimmy Dodd would give him no peace if he did so. So he put the plane's nose resolutely into the wind, watching his speed indicator drop from a hundred miles per hour to eighty, sixty, forty—less.
