in the shadowy Purgatorio.

At the stroke of midnight each spirit who has passed through this ordeal with a steadfast mind will be wafted to upper regions to the rest of the blessed.

Signed by the Council of Ten, as represented by Witch Winnie, of the Amen Corner, and Little Breeze, of the Hornets; and sealed with the great seal of our office, this —— day of —— 18—.

Seal.

These preparations were going on simultaneously with the investigation of the robbery, and served in a measure to relieve the tension to which we were all subjected. Still the trouble was there, and we never quite forgot it. Mr. Mudge called twice, and made inquiries, from which Winnie inferred that he was hopelessly puzzled. Milly was sure that he had found a clew, but if so, he did not impart his discoveries.

The mystic evening arrived. Cynthia, who, for some reason inexplicable to us, was in a highly self-satisfied and gracious mood, invited Polo to sleep with her in order that she might be able to attend the party. It was necessary to prefer this request to our corridor teacher, Miss Noakes, who gave us a very grudging consent; but we cared very little for her iciness since we had effected our wishes.

The girls met in the studio, where all were draped in sheets, a small mask cut from white cotton cloth tied on, and a pillow case fitted about the back of the head in the fashion of a long capuchin hood. When thus robed our dearest friends were unrecognizable. Then, marshalled by Winnie, the company of spectres paraded through the hall and down the main staircase. Miss Noakes and the other teachers stood in their doors and watched the procession, but as it was known that we had Madame’s permission no attempt was made to stop us, and we passed on unabashed. Arrived at the lower floor each of the guests was securely blindfolded and conducted by one of our ten down the cellar stairs, and through winding passages to the laundry, which had been converted for the evening into an auditorium, sheets having been hung on clothes-lines across one end, and the space in front filled with camp chairs brought from the recitation rooms. The set tubs on one side of the improvised stage were fitted up as boxes, while a semi-circle of clothes-baskets marked the space assigned to the comb orchestra. As fast as the girls arrived in the laundry they were seated, and when the last instalment was in position the lights were turned nearly out, and they were told to remove the handkerchiefs which bandaged their eyes. At the same time the comb orchestra, led by Cynthia, struck up a dismal dirge-like overture, broken in upon at intervals by a tremendous thump with a potato masher on the great copper boiler. The curtain was drawn slowly aside, the lights suddenly turned on, and the play began. Adelaide made a very beautiful Fabiola. Winnie acted the part of Pancratius with great expression. Milly looked the saintly Agnes to perfection. I was Sebastian. We did not indulge in all the dialogue with which the book is overloaded. Our play was rather a series of tableaux, for which I had painted the scenery with the assistance of the other art students. Professor Waite had borrowed various classical properties from his brother artists for us. The plaster casts of the studio were made to serve as marble statues, and Madame had sent us several palms in urn-shaped pots.

When the play was nearly over, Polo, who had acted as doorkeeper, made her way behind the scenes and took my attention from the prompter’s book with the horrified whisper, “If you please, there are two girls out there that are boys.”

“Who? Where? How do you know it?” I asked in a breath.

“They came in at the end of the procession, without any guides, and sat down near the door, apart from the others. One is little enough to be a girl, but the other is taller, even, than Miss Adelaide.”
