Soon he found one that seemed to suit him, for he tied his red scarf upon a greasewood-bush. Then, returning to the car, he clambered in, and, muttering, broke his long silence: “This ain’t no air-ship, but I’ve outfiggered thet damn wash.” He backed up the gentle slope and halted just short of steeper ground. His red scarf waved in the wind. Hunching low over the wheel, he started, slowly at first, then faster, and then faster. The great car gave a spring like a huge tiger. The impact of suddenly formed wind almost tore Madeline out of her seat. She felt Nels’s powerful hands on her shoulders. She closed her eyes. The jolting headway of the car gave place to a gliding rush. This was broken by a slight jar, and then above the hum and roar rose a cowboy yell. Madeline waited with strained nerves for the expected crash. It did not come. Opening her eyes, she saw the level valley floor without a break. She had not even noticed the instant when the car had shot over the wash. A strange breathlessness attacked her, and she attributed it to the celerity with which she was being carried along. Pulling the hood down over her face, she sank low in the seat. The whir of the car now seemed to be a world-filling sound. Again the feeling of excitement, the poignancy of emotional heights, the ever-present impending sense of catastrophe became held in abeyance to the sheer intensity of physical sensations. There came a time when all her strength seemed to unite in an effort to lift her breast against the terrific force of the wind—to draw air into her flattened lungs. She became partly dazed. The darkness before her eyes was not all occasioned by the blood that pressed like a stone mask on her face. She had a sense that she was floating, sailing, drifting, reeling, even while being borne swiftly as a thunderbolt. Her hands and arms were immovable under the weight of mountains. There was a long, blank period from which she awakened to feel an arm supporting her. Then she rallied. The velocity of the car had been cut to the speed to which she was accustomed. Throwing back the hood, she breathed freely again, recovered fully. The car was bowling along a wide road upon the outskirts of a city. Madeline asked what place it could be. “Douglas,” replied Link. “An’ jest around is Agua Prieta!” That last name seemed to stun Madeline. She heard no more, and saw little until the car stopped. Nels spoke to some one. Then sight of khaki-clad soldiers quickened Madeline’s faculties. She was on the boundary-line between the United States and Mexico, and Agua Prieta, with its white and blue walled houses, its brown-tiled roofs, lay before her. A soldier, evidently despatched by Nels, returned and said an officer would come at once. Madeline’s attention was centered in the foreground, upon the guard over the road, upon the dry, dusty town beyond; but she was aware of noise and people in the rear. A cavalry officer approached the car, stared, and removed his sombrero.
