Within the second hour the wind rose to what Folsom judged was fifty miles an hour. It had also backed several points until it was blowing from almost due north. The wind carried the scent of the icy wastes from the Great Barrier, less than two hundred miles north, bringing with it the same fierce temperatures and flying. ice spicules that scoured the ice of the polar cap into tortured shapes. Folsom traveled now with the compass constantly in his hand, fighting to keep them on a course leading generally westward. But the proximity of the north magnetic pole made it all but useless for more than general direction keeping. As the wind increased, so did the labor involved in walking. The snow had drifted to three and four feet deep in some places, and where it hadn't drifted at all it stood at least two feet deep. The snowshoes were of some help in keeping them above the crust, but the extra work of adjusting their gait to the peculiarities of the webbed shoes made Folsom wonder if they were not just trading one exhaustion for another. The only thing that seemed to be in their favor was that the top of the cliffs was fairly level, sloping gently downhill to the south. Folsom was under no illusions that the Russians would stop to wait out the storm. They would assume that their quarry was also taking every advantage the storm offered. Once they found the damaged lifeboat but no sign of a camp, it would not take them long to conclude that they were heading for the Norwegian naval base. The only hope the Russians would then have would be to cut them off before they gained the naval installation. And Folsom knew damned well that, if they did call for help, either the submarine or Soviet aircraft would arrive in quick order to shell the hell out of them. With these thoughts to keep him company, Folsom grimly forced them on through the Arctic desert.
For Teleman the hours passed endlessly in a haze of pain as tired muscles and joints protested every movement. The cold was more than insidious. In his weakened condition it was waiting to kill him if just once he let down his guard. His only hope was to keep moving, forcing his body to make optimum use of the slender reserves twenty-four hours of sleep had rebuilt. What would happen when these reserves were exhausted he knew very well. At one time Teleman had voraciously read everything he could find on Arctic and Antarctic exploration. He knew, for instance, that in spite of the tremendous will to live that had infected Scott and his crew in the Antarctic, it had been impossible for them to travel that last eleven miles to the supply cache that had literally meant life or death. And now he understood why. He was fast reaching that point where it becomes impossible for the body to put out that last ounce of strength, that last bit of will that forces dying muscles to one more movement. The intense cold of the Arctic activated the body's main defense system against cold, involuntary shivering, but it also killed after a few hours. Shivering is an involuntary or autonomous muscle movement that cannot be controlled consciously. And it takes energy to shiver, and a prolonged bout at last saps all reserves. Then the body dies because there is simply no more heat to power the machine.
Teleman was shivering, shivering violently. He had never been so cold in his life. And in spite of the Arctic clothing and the heavy parka, the cold cut as if they were merely tissue. The first touches of frost had long since begun to reach through the insulated soles of his boots. By now, after four hours of walking, his feet were completely numb. He hated to think of what was going to happen when his feet and hands began to thaw… if they ever did.
From then on he stumbled constantly, half supported by the giant McPherson, whose strength seemed endless. Through the snow mask Teleman could feel the skin of his face grow numh, then contract in the cold as if it were trying to pull his skull apart. Feebly he rubbed his cheeks and nose with gloved hands, and the pain of even this faint bit of returning circulation was fantastic.
As they traveled farther across the rough crags of the rear cliff tops, clambering over rock outcroppings to slide painfully down the snow-and ice-slick far sides, Teleman marveled, with the part of his mind that was still conscious, at the strength that McPherson, was exhibiting. Even now as Folsom and Gadsen were beginning to slow, their movements becoming more and more unsteady as they fought against the exhausting wind and cold, McPherson still half carried him, still showed no signs of weariness.
