"Just think of an extra man in San Gabriel!" shouted the girls in chorus; while Mrs. Wilbur appealed confidentially to Mrs. Sanderson to settle the impending difficulty.

"We were expecting six couples from Pasadena, and now, at the last moment, Ethel Walton sends word that the giddy widow who was to have chaperoned her party is ill, obliging them to bring a maiden lady who doesn't dance," she exclaimed.

"Delightful!" exclaimed the girls. "How jolly to boast a rover, and dear Mr. Eastman at that."

"Won't he be popular?" Mrs. Wilbur added, aside to Mrs. Sanderson, who was at that moment glancing interrogatively at Sidney.

The young man divined his mother's signal, for he came to her side with unusual alacrity.

"The very thing," the lady replied to his earnest undertone. "The arrangement will be quite proper, and I am sure that Mrs. Wilbur will relinquish you for Mr. Eastman. Won't you, my dear?" the lady continued, turning suddenly to Mrs. Wilbur, who was now beginning to suspect that Sidney was quite satisfied to obey the suggestion of his mother.

"It will be so interesting to watch Mariposilla dance in the cotillion," Mrs. Sanderson pursued, bravely. "Dear Mrs. Wilbur will excuse you, for my sake, I am sure, Sid," she added, sweetly, as she turned from that somewhat ruffled young woman to the Spanish child, who was prettily pleading her ignorance of cotillions.

"Never mind, dear," she said, coaxingly, to the timid girl, "you dance divinely, and Sid will take you through the figures beautifully."

I saw that Mrs. Wilbur was chagrined and angry, for a hot flush had dyed her cheeks, when she replied that of course Mr. Sanderson could do as he chose. As far as she was concerned she would be greatly pleased to dance with Mr. Eastman, having formerly refused him her partnership on account of an early engagement with Mr. Sanderson.

"My mother appears to have solved our difficulties. Mr. Eastman certainly surpasses me as a partner, and as there is no robbery in a beneficial exchange, with Mrs. Wilbur's permission, I will dance with Miss Del Valle," the young man responded, indifferently.
