It had been a head-on collision between the two trains. In some way, nobody knew how, there had been a misunderstanding of orders, and the east-bound train, instead of waiting at the next switch, had come on toward the usual passing place. In the shock of meeting, its engine had reared and ploughed its way over the other and the two monsters lay upon the ground, a mass of twisted scraps of iron. One engineer had stuck to his post, the other had jumped, as had both the firemen. One was dead, the other three all severely injured. Among the train crews and the passengers of the day coaches there were a number of broken limbs and many severe cuts, bruises, and shocks. From the east-bound train another physician appeared, and he and Elizabeth worked over the injured, sometimes together, sometimes separately. Adams was constantly beside her, ready to carry out her directions. He brought water, held bandages, helped her to put them on, handed instruments, and kept her belongings close at hand. She had cast aside her hat and rolled her sleeves above her elbows, and as she bent a flushed, perspiring, and absorbed face above her work, forgetful alike of her own and of his personality, she seemed so utterly unlike the woman he had known for the last three days that a feeling of bewilderment and estrangement began to creep over him. Once she complimented him upon his watchfulness and dexterity, and the smile with which she did it set his heart to throbbing again and bridged what had seemed like a chasm between the two Elizabeths. He watched her long, slender, strong hands as she deftly and rapidly manipulated the bandages, felt for a broken bone, or used her instruments, and a great, awed wonder, the homage of intelligence to skilled capacity, mingled with the adoration that filled his soul. He began to torture himself with doubts and questions. Could such a woman care for him? What was there about him that could appeal to so rare a prize? What had he to offer in character, or personality, or achievement, or promise? And the more he doubted the more intense became his desire to know. Elizabeth rose from her knees beside a man whose crushed foot she had been bandaging. "Is there anybody else?" she said to Adams. Her hands and arms were smeared with blood stains, and upon her dress there were smirches of earth and blood. But Adams saw only that the red sunset rays gilded her brown hair into a halo. "No," he answered, "I think not. The last bruise has been cared for and the last hysterical woman has quit crying. Now you must rest and refresh yourself and have some dinner. An engine is coming from the west to take the cars of the east-bound train back to the next station and all the passengers who wish can go there; and to-night another train will continue on their way those for California. It will be here before long, but perhaps it will be possible to get something to eat first."
