"I have an engagement with the dentist," was the doleful reply.

"Well, the day after?"

"Let me see," mused Anna. "Oh, no!" she added, hastily. "I could not start on a journey or begin any work on a Friday; it would not be lucky, you know!" Then she flushed and looked toward Miss Irene, who shook her head significantly and wrote in her note-book, "Superstitious practice No. 4."

As it was Emily's birthday, the girls had been invited to stay for luncheon. Emily now led the way to the dining-room, where a pretty table was spread. Everything was as dainty as good taste and handsome auxiliaries could make it: the snowy damask, fine glass, and old family silver; the small crystal bowls filled with chrysanthemums, and at each plate a tiny bouquet.

Mr. Mahon was down town at his business, but there stood Mrs. Mahon, so kind and affable; and the boys and girls of the family were waiting to take their seats. The party paused, while, according to the good old-fashioned custom (now too often neglected), grace was said; and Cousin Irene, contemplating the bright faces and pleasant surroundings, thought she had seldom seen a more attractive picture. But now she noticed that May, after a quick look around, appeared startled and anxious. The next moment the foolish girl exclaimed:

"O Mrs. Mahon, there are thirteen of us here! You do not like to have thirteen persons at your table, do you? Pardon me, but I'm so nervous about it!"

A shadow of annoyance flitted across Mrs. Mahon's motherly countenance, but she answered gently: "My dear, I never pay any attention to the superstition. Still a hostess will not insist upon making a guest uncomfortable. Tom," she continued, addressing her youngest son, "you will oblige me by taking your luncheon afterward."

Tom scowled at May, flung himself out of his chair, mumbled something about "stuff and nonsense;" and, avoiding his mother's reproving glance, went off in no amiable humor.

May was embarrassed, especially as she felt Miss Irene's grave eyes fixed upon her. But Mrs. Mahon was too courteous to allow any one to remain disconcerted at her hospitable board. With ready tact she managed that the little incident should seem speedily forgotten. After a momentary awkwardness the girls began to chatter merrily again, and harmony was restored.

On their return to the drawing-room, May whispered to Miss Graham: "I hope Mrs. Mahon will excuse me for calling her attention to the number at table. I did not mean to be rude, and I suppose it is silly to be so superstitious; but, indeed, I can not help it."
