The members of the Cowslip Room were always ready for some diversion. They wondered what kind of a practical joke Avelyn was going to play on Irma. They took particular care to decoy their victim upstairs at four o'clock. As a bait, Ethelberga offered to lend Irma her manicure set. They were rubbing pink powder on Irma's almond-shaped nails when a rap came at the door. "Entrez!" shouted Janet casually. It was a demure-eyed junior who made her appearance, carrying a large parcel. "This has just come, and it's for your room, so I brought it up," she announced, dumping it down on the bed, and leaning over to read the address. "Miss Irma Ridley. Wish it had been Miss Dorothy Elston. I've no luck. Ta-ta!" and she waved a rather impertinent hand, and trotted away. Irma jumped up, upsetting the box of manicure powder, and scattering the other implements over the floor. "It's never my box!" she exclaimed. At that psychological moment Avelyn entered the room. "I didn't expect it until to-morrow," rejoiced Irma. "They must have sent it by carrier instead of by post. Lend me your scissors, Janet. Oh, I'm just dying to look!" The parcel was a large cardboard box done up in rather untidy brown paper. It had evidently suffered considerably on the journey. Irma cut the string with the utmost haste, and began to tear off the wrappers and open the box. "I know Mother will have chosen me something pretty," she purred. "Mother's got such lovely taste, and she wrote that she'd seen the very thing, and was sure I should like it." "It's well wrapped up," remarked Janet. Irma was removing sheet after sheet of tissue paper with a pleased giggle. At last she reached the core of the package, and unfolded--not a smart new frock, but her own ordinary school evening dress. Her stare of blank astonishment was comical. "What's this? What have they sent me?" she gasped. But her room-mates were collapsing in various attitudes of mirth, and she understood. For a moment two red spots flared in her cheeks, then she had the sense to take the joke with a good grace. If she was angry, the others shouldn't have the triumph of seeing her annoyance. "You geese!" she remarked. "I might have known the box couldn't arrive to-day. So this is why you hauled me upstairs, is it? Oh, go on and laugh if you like! It doesn't hurt me. I don't mind." She hung the dress up again in her wardrobe, and folding the sheets of tissue paper, appropriated them. "I've been wanting some tissue paper," she said airily. The girls restrained themselves and sobered down. "You're a trump, Irma!" declared Avelyn. "It was too bad, but we couldn't help laughing," murmured Janet. "Poor old Irmie, you took it sporting!" sympathized Ethelberga. "You'll like your dress all the more when it really comes," comforted Laura.
