She was battling to hold the car in the principal rut. She snatched the windshield open, and concentrated on that left rut. She felt that she was keeping the wheel from climbing those high sides of the rut, those six-inch walls of mud, sparkling with tiny grits. Her mind snarled at her arms, "Let the ruts do the steering. You're just fighting against them." It worked. Once she let the wheels alone they comfortably followed the furrows, and for three seconds she had that delightful belief of every motorist after every mishap, "Now that this particular disagreeableness is over, I'll never, never have any trouble again!" But suppose the engine overheated, ran out of water? Anxiety twanged at her nerves. And the deep distinctive ruts were changing to a complex pattern, like the rails in a city switchyard. She picked out the track of the one motor car that had been through here recently. It was marked with the swastika tread of the rear tires. That track was her friend; she knew and loved the driver of a car she had never seen in her life. She was very tired. She wondered if she might not stop for a moment. Then she came to an upslope. The car faltered; felt indecisive beneath her. She jabbed down the accelerator. Her hands pushed at the steering wheel as though she were pushing the car. The engine picked up, sulkily kept going. To the eye, there was merely a rise in the rolling ground, but to her anxiety it was a mountain up which she--not the engine, but herself--pulled this bulky mass, till she had reached the top, and was safe again--for a second. Still there was no visible end of the mud. In alarm she thought, "How long does it last? I can't keep this up. I--Oh!" The guiding tread of the previous car was suddenly lost in a mass of heaving, bubble-scattered mud, like a batter of black dough. She fairly picked up the car, and flung it into that welter, through it, and back into the reappearing swastika-marked trail. Her father spoke: "You're biting your lips. They'll bleed, if you don't look out. Better stop and rest." "Can't! No bottom to this mud. Once stop and lose momentum--stuck for keeps!" She had ten more minutes of it before she reached a combination of bridge and culvert, with a plank platform above a big tile drain. With this solid plank bottom, she could stop. Silence came roaring down as she turned the switch. The bubbling water in the radiator steamed about the cap. Claire was conscious of tautness of the cords of her neck in front; of a pain at the base of her brain. Her father glanced at her curiously. "I must be a wreck. I'm sure my hair is frightful," she thought, but forgot it as she looked at him. His face was unusually pale. In the tumult of activity he had been betrayed into letting the old despondent look blur his eyes and sag his mouth. "Must get on," she determined.
