On the far side of the street she plunged into a comparatively quiet square, where the fog had lifted somewhat, and was no longer of such Cimmerian blackness, but merely a drifting and bewildering white mist.
The pillar-box at the corner loomed faintly through it, and Christina had just dropped her packet of letters into it, when there struck upon her ears the soft cry of a little child. There was such a note of fear, of lonely misery, in that soft cry, that Christina, a child-lover to the core of her being, paused, and listened intently. Everything about her was very still; the square was a quiet one, though separated only by a short street from a main thoroughfare; and, excepting for the distant noise of traffic and shouting, nothing was to be heard, until again the little whimpering cry became audible on Christina's right.
"What is it?" the girl said gently. "Don't be frightened, dear. I'll take care of you," and as she spoke, she heard a gasp of relief, and a shaking, childish voice exclaimed:
"Baba's most drefful fightened; please take Baba home."
"But where is Baba?" Christina was beginning cheerily, when, through the fog, she caught sight of a tiny figure coming quickly towards her, and, stooping down, she gathered close into her arms a little child, of perhaps three years old, a little child who clung to her with a desperate, terrified clutch, lifting a tear-stained face to hers.
"Take Baba home," the baby voice wailed again, and as the fog rolled back a little more, Christina saw that the child was no street waif, but obviously the daintily-clad darling of some great house. Her golden head was bare, and the tangle of curls was like a frame about the lovely little face, whose great blue eyes looked appealingly into Christina's own. A red woollen cloak hung over the child's shoulders, but as the cloak fell back, Christina saw that her frock was chiefly fashioned of exquisite filmy lace, and that a string of pearls was fastened round the little white throat.
"Where is Baba's home?" she questioned softly, lifting the child right into her arms, and kissing the flower-like face, on which the tears still lay like dewdrops in the heart of a rose. "Tell me where you live, sweetheart, and I will take you home."
"Baba doesn't know where she lives," the child shook her yellow curls, and her big eyes filled again with tears. "Baba's awful, drefful fightened. The door was open—and Baba did just run out to see the pretty horses—and then—it was all black—and Baba was lost."
"I don't think Baba ought to have come out by herself in a fog," Christina said, a gentle reproof in her tones; "and now we must try to find out where your home is, little girl. Tell me what your name is—besides Baba."
"Baba—Mummy's Baba—dat's all," the baby answered, with a conclusive shutting of her pretty mouth. "Baba's forgot her other name—she's only just Mummy's Baba."
