The grandmother, resplendent in great gold ear-rings, chattered garrulously in Spanish, while Mrs. Sanderson smiled indulgently and regally upon all.

The lady was in demi-evening toilet, and the delicate tone of her French-gray gown, embellished with lace and caught at the half low throat by flashing jewels, was to Mariposilla a revelation. To the simple child the handsome woman appeared a wonderful vision, from which she could not withdraw her eyes. For the first time she beheld Mrs. Sanderson in her most captivating rôle; the conventional habit of day, exchanged for one of rare artistic beauty, had given to the lady a sudden fascinating youth which was startling. In the less impertinent light of evening, the encroachments of time were effaced. The aristocratic features and dazzling teeth belied the years of the woman whose supreme object had been their preservation. The beautiful hands, ablaze with jewels, seemed to smite the humble room with light, when the lady caressed, with amused vanity, the bewildered child she had so perfectly enthralled.

"Fly, Butterfly," she coaxed, as Mariposilla lingered by her side; "Sid is starving! and so are we all. Cast aside the old, dull frock and dazzle us in the new one."

I had always noticed that Mrs. Sanderson was exuberant in the evening. To her theatrical nature there was something exhilarating in the flicker of artificial lights. When high noon told her unpleasant truths, she forgot them the same evening, amid shaded lamps and candles. An open fire could warm her usually chilly sympathies, until she sometimes forgot her selfishness in genuine kindness. At such times, occasionally, she grew honest, and often liberal.

She had declared that misfortunes and ugly surroundings would soon make her a devil. It was only when deceived by luxury and flattery that she was capable of good thoughts.

"I am naturally depraved before I have had my bath and my early coffee," she would say, jestingly, to the amazement of the literal, whom she delighted to shock. "Sid, the scamp, knows better than to cross me before luncheon. In the evening he is safe. When he sees that I am in the ecstasies of dotage, a perfect old egotist, happy with illusions, he imposes upon me shamefully."

Strange, worldly woman that she was, it was impossible to condemn her brilliancy.

She had told us that her great grandmother was a Frenchwoman of rank, and as I regarded her this Christmas Eve, I seemed to see the proud dame of the fallen monarchy living again in the imperious form of her descendant.

I had not completed my hasty toilet when Mariposilla came flying to my door, breathless. She held in her arms the dress of cream and gold.

"See," she cried; "they have made a mistake! and I must again part with the beautiful dress. Can I not wear it this once that my friends may see it?"
