"I know of nothing more, Miss Minturn," she said; but even as she spoke there was a nervous rustle apparent among some of the audience. "Still I am quite sure that a ghostly surprise, not down on my pragramme, had been planned for us. Perhaps this will elucidate my meaning," Katherine explained, and, bringing to light something, which she had until then concealed behind her, she shook out and held up to view a white robe, made of a sheet, and also a white mask. Groans and laughter greeted this announcement and display. "Oh! who has given us away? Who has told you, Miss Minturn?" came breathlessly from various quarters of the room. "No one 'has given the secret away'--no one has 'told' me anything," she replied. "The discovery was an accident. I was obliged to slip up to my room for something forgotten, just before it was time to open the meeting. As I reached the end of the hall I heard voices, and, being arrayed in the dentist's garb with only a domino over it, I did not wish to be seen. I fled into the closet there, and the next moment two juniors passed, carrying something in their arms, wrapped in shawls. I heard one say, 'When I give the signal, Miss Blank will touch the button and put out the lights.' When they were beyond hearing I stole from the closet and found a small bundle at my feet. Investigation revealed this ghostly garb, and, if I am not mistaken, those shawls, in yonder corner, contain several others." The room was very still for a moment after Katherine concluded, and there were some very red faces, here and there, among the audience. Suddenly Clara Follet sprang to her feet, and, addressing the president, said: "Miss Walton, as I am the leader in this affair, may I make an explanation?" "Certainly. Comrades, Miss Follet has the floor."
