It was Christmas eve—not the time for a baby girl to be travelling. Then his glance fell again on the black bow among the yellow curls and on the white dress with its black shoulder-knots, and the explanation came to him. An orphan, of course, on her way West to a new home, in charge of the matter-of-fact nurse who was dozing comfortably in the corner of her seat. To whom was she going? Perhaps to grandparents, where she would be spoiled and wholly happy; or quite possibly to more distant relatives where she might find a grudging welcome. Dear little embryo woman, with her sympathetic heart already attuned to the world’s gamut of pain. She should have been dancing under a Christmas tree, or hanging up her tiny stocking in the warm chimney-corner of some cozy nursery. The heart of the man swelled at the thought, and he recognized the sensation with a feeling of surprised annoyance. What was all this to him—to an old bachelor who knew nothing of children except their infantile ailments, and who had supposed that he cared for them as little as he understood them? Still, it was Christmas. His mind swung back to that. He himself had rebelled at the unwelcome prospect of Christmas eve and Christmas day in a sleeping-car—he, without even nephews and nieces to lighten the gloom of his lonely house. The warm human sympathy of the man and the sweet traditions of his youth rose in protest against this spectacle of a lonely child, travelling through the night toward some distant home which she had never seen, and where coldness, even neglect, might await her. Then he reminded himself that this was all imagination, and that he might be wholly wrong in his theory of the journey, and he called himself a fool for his pains. Still, the teasing interest and an elusive but equally teasing memory held his thoughts.

Darkness was falling, but the porter had not begun to light the lamps, and heavy shadows were rising from the corners of the car. Dr. Van Valkenberg’s little neighbor turned from the gloom without to the gloom within, and made an impulsive movement toward the drowsy woman opposite her. The nurse did not stir, and the little girl sat silent, her brown eyes shining in the half-light and her dimpled hands folded in her lap. The physician leaned across the aisle.

“Won’t you come over and visit me?” he asked. “I am very lonely, and I have no one to take care of me.”

She slid off the seat at once, with great alacrity.

“I’d like to,” she said, “but I must ask Nana. I must always ask Nana now,” she added, with dutiful emphasis, “’fore I do anyfing.”

She laid her hand on the gloved fingers of the nurse as she spoke, and the woman opened her eyes, shot a quick glance at the man, and nodded. She had not been asleep. Dr. Van Valkenberg rose and lifted his visitor to the seat beside him, where her short legs stuck out in uncompromising rigidity, and her tiny hands returned demurely to their former position in her lap. She took up the conversation where it had been interrupted.

“I can take care of you,” she said, brightly. “I taked care of mamma a great deal, and I gave her her med’cin’.”

He replied by placing a cushion behind her back and forming a resting-place for her feet by building an imposing pyramid, of which his dressing-case was the base. Then he turned to her with the smile women loved.

“Very well,” he said. “If you really are going to take care of me I must know your name. You see,” he explained, “I might need you in the night to get me a glass of water or something. Just think how disappointing it would be if I should call you by the wrong name and some other little girl came!”

She laughed.
