When the porter's "last call for luncheon" brought that flutter of satisfaction by which a bored parlor-car welcomes even such a trivial diversion as food, Dr. Blake waited a fair interval for her toilet preparations, and followed toward the dining-car. He smiled a little at himself as he realized that he was craftily scheming to find a seat, if not opposite her, at least within seeing distance. On a long and lonely day-journey, he told himself, travelers are like invalids--the smallest incident rolls up into a mountain of adventure. Here he was, playing for sight of an interesting girl, as another traveler timed the train-speed by the mile-posts, or counted the telegraph poles along the way. So he came out suddenly into the Pullman car ahead--and almost stumbled over the nucleus of his meditations. She was half-kneeling beside a seat, clasping in her arms the figure of a little, old woman. He hesitated, stock still. The blonde girl shifted her position as though to take better hold of her burden, and glanced backward with a look of appeal. The doctor came forward on that; and his sight caught the face of the old woman. Her eyes were closed, her head had dropped to one side and lay supine upon the girl's shoulder. It appeared to be a plain case of faint. [Illustration: ANNETTE] "I am a physician," he said simply, "Get the porter, will you?" Without an instant's question or hesitation, the girl permitted him to relieve her, and turned to the front of the car. Other women and one fussy, noisy man were coming up now. Dr. Blake waved them aside. "We need air most of all--open that window, will you?" The girl was back with the porter. "Is the compartment occupied? Then open it. We must put her on her back." The porter fumbled for his keys. Dr. Blake gathered up the little old woman in his arms, and spoke over his shoulder to the blonde girl: "You will come with us?" She nodded. Somehow, he felt that he would have picked her from the whole car to assist in this emergency. She was like one of those born trained nurses who ask no questions, need no special directions, and are as reliable as one's instruments. The old woman was stirring by the time he laid her out on the sofa of the compartment. He wet a towel in the pitcher at the washstand, wrung it out, pressed it on her forehead. It needed no more than that to bring her round. "Only a faint," said Dr. Blake; "the day's hot and she's not accustomed to train travel, I suppose. Is she--does she belong to your party?"
