The thought of the mayonnaise settled the matter. Mr. Smith hastily wrote an account of the trying situation, and concluded his note with a solemn demand upon "dear old Van" to fill the vacant place, "in the holy name of the class of '68, and for love of your old classmate, R. Smith."

Presently the person thus adjured returned to his hotel, and with a somewhat puzzled expression read the adjuration. "R. Smith," he murmured, reflectively. "I think I do remember a Dicky Smith, from Philadelphia, at Columbia. But he wasn't in my class, and my class wasn't '68, but '76, and I don't remember ever saying a dozen words to him. He's got a good deal of cheek, whoever he is—and he, and his dinner, and his missing man may all go to the devil together! His invitation is absurd!" And with this ultimatum Mr. Livingstone laid the letter and envelope neatly together, preparatory to tearing them into fragments.

But before this purpose was accomplished, another view of the situation came into his mind. "I don't see why I shouldn't go," he thought. "I've been muddling all day with this wretched wool man—which is a bore, even if I have made a pretty good bargain with him for next season's clip; and Ned hasn't come to time, which is another bore, for now I'll have to eat my dinner alone. And this Dicky Smith writes like a gentleman, even if he is cheeky; and he certainly seems to be in a peck of troubles about his missing man, and his thirteen at table, and the rest of it. Why, it's a regular adventure! And to think of having an adventure in Philadelphia, of all places in the world! By Jove, I'll go!"

"How very, very good of you, Mr. Livingstone, to come to our rescue!" It was Mrs. Rittenhouse Smith who spoke, and she spoke in a guarded tone; for Livingstone was among the last to arrive, and she had no desire to publish among her guests the catastrophe that so nearly had overtaken her.

"And I know," she continued: "that you will understand how sorry I am that this first visit of Mr. Smith's old friend to our house should be under such peculiar circumstances. But you will have your reward, for you are to take out the very prettiest and the very brightest girl here. Come and be rewarded!" And Mrs. Smith slipped her hand upon her benefactor's arm, and piloted him across the room.

"Miss Winthrop, permit me to present Mr. Livingstone. Miss Winthrop is half Boston and half European, Mr. Livingstone; and as you, after these ten years abroad, must be wholly European, you can cheer each other as fellow foreigners in the midst of Philadelphia barbarism"—with which pleasant speech the hostess turned quickly to receive the last arrival (a man, of course; only a man would dare to be even near to late at one of Mrs. Rittenhouse Smith's dinners), and then, standing beside the doorway, with Mr. Hutchinson Port, marshalled her company in to dinner. It was a comfort to her to know that for once in his fault-finding life Mr. Port would be compelled, since he was to be seated beside his hostess, to eat his food without abusing it.

Just at this time two things struck Mrs. Smith as odd. One was that as she presented her handsome guest to Miss Grace Winthrop she certainly had felt him start, while his arm had trembled curiously beneath her hand. The other was that as Mr. Rittenhouse Smith left the drawing-room, passing close beside her with Miss Winthrop upon his arm, he made a face at her. The first of these phenomena struck her as curious. The second struck her as ominous. Had it been possible she would have investigated the cause of Mr. Smith's facial demonstration. But it was not possible. She only could breathe a silent prayer that all would go well—and the while sniff anxiously to discover if perchance there were a smell of scorching duck.

Mrs. Smith would have been still more mystified could she have been cognizant at this juncture of her husband's and of Miss Grace Winthrop's and of Mr. Livingstone's thoughts.
