Jean did not leave the cozy corner until she was sure Marjorie had joined the dancers. She leaned back against the pillows, faint with astonishment and dismay. What should she do? One idea after another rushed through her brain and confused her more and more. She must act quickly, or it would be too late. Stealing into the outer hall she found the black robe and mask Jack had left there and she put them on over her Old Mother Hubbard costume. She knew she was not as tall as Jack was, but still there was not such a great difference and it was worth the risk. Slowly wending her way back into the main room, she found the sister of charity just about to dance with a Little Boy Blue. She put her arm round Marjorie and drew her away before Little Boy Blue realized what was happening.

Marjorie herself was so astonished she could say nothing at first, but after a moment whispered, "Jack, how careless; you must go. We're going to unmask after this dance and if you're found here I'll be expelled to-morrow." But the monk answered never a word, but danced as smoothly and gently as though he had heard nothing. Again Marjorie whispered, "Oh, Jack, you must go! Don't wait another minute or I'm lost."

Just then the music stopped and some one cried, "Masks off!" and there was a general pulling off of masks amid peals of laughter. As Marjorie gazed into Jean's face a look of terror settled over her own as she gasped "You!" but Jean said quietly, "We'll talk about it later up in your room. Don't leave until the others do," and she hurried away. There were many surprises at the unmasking, but the greatest was Jean's. Several of the girls, among them Elizabeth and Sallie, declared they had recognized her earlier in the evening in another costume, but she refused to answer except as she whispered in Elizabeth's ear, "Don't ask too many questions. Trust me; it's all right."

Then the refreshments were served and still there was time for a few more dances. Jean went to the piano and offered to play so that the pianist might dance a little. Really, Jean needed to think and be away from the girls. She hardly knew what she was playing, so absorbed was she with the thought of what Marjorie had done and what she as proctor of fourth floor must do before very long. Such a thing could not be passed by unnoticed, and still what a terrible thing it would be to have Marjorie expelled through her. She had heard of people sacrificing duty for friendship, and she wondered what she would do when it came time to decide. Once the room seemed to grow black and she thought she would fall off the stool, but by a supreme effort she shook off the approaching faintness and finished the waltz she was playing. Then she arose and left the piano and walked over to Mrs. Thompson. "I think I will be excused, if you please, Mrs. Thompson. I feel a little tired. It's been a splendid party. Good night."

Elizabeth was watching her and noticed her pallor and swaying body. "What is the matter, Jean? What has happened? This isn't a bit like you. Can I help you?"

"No, Elizabeth; I shall be all right as soon as I get upstairs. Please don't leave until the others do." Then she crept up the stairs and when she entered her own room she closed the door and locked it. She quickly tore off the two costumes, leaving the black one on the couch where Elizabeth would be sure to see it; then she threw the Old Mother Hubbard dress into a trunk which was in her closet, closed the lid, and locked it. Putting on her kimona she sat down to think and wait for the girls to come upstairs.

When Elizabeth entered the room, Jean was more like herself and talked gayly about the girls' costumes. "I'll go out in the corridor and put out the lights, and I've got a message to deliver to one of the girls, so don't wait up for me." She put out all the lights on fourth floor and then walked slowly up and down the corridor three or four times before knocking softly at Marjorie's door. Without waiting for her to reply, Jean entered the room and closed the door gently after her.

"Marjorie, remember I come here to-night as proctor as well as friend. What you have done is awful. I can hardly think about it calmly. How did you dare think of such a thing? You've broken every rule of our house, you've deceived every girl here and Mrs. Thompson as well, you've committed an offense worthy of expulsion, you've disgraced yourself and all the rest of us. Now what's to be done? I'm the only girl who knows what has happened, although others were mystified at my being the monk and the Mother Hubbard, too. That will be forgotten in a day or two, but what you have done is of more serious import. You wonder why I dressed up in Jack's costume? I was tired of dancing and went out into the cozy corner beyond the lemonade table to rest a little. Before I had been there long you and Jack came and I could not help overhearing your conversation. After he had gone I knew you would go back to the other rooms alone and every one would wonder where your constant attendant had gone. Questions would be asked and you would have to give some sort of an explanation. The idea came to me to put on Jack's costume for the remainder of the evening and save you from a difficult position. Now I have given you an explanation of my conduct and I ask for one of yours."

"There isn't one, Jean; except that when I told Jack about the party he suggested that he come out, too, dressed as a monk. He planned everything so well that I thought there was no danger and it was a lark. I was tired of dancing with girls and I longed for a dance with a real man, and you know Jack dances divinely. I guess Ashton is no place for me, after all, and you might as well have it out to-morrow and get me expelled. I don't mind leaving college, but I hate to go home and have Jack so far away. It's a long time till June, and I'll be awfully lonesome out there without him."

"No, Marjorie; I don't want you publicly expelled. I'm sorrier for you than I've ever been for any one in all my life. I wish I were not proctor to-night, and I'd say nothing about it. As it is I shall not report you unless you refuse to comply with my plans. You are to leave college to-morrow. You'll say you were called home unexpectedly. I'll leave the reason to you, but I must see you on the train for Detroit and see the telegram you send home to your father to meet you. Jack is to know nothing about it until you write him from Detroit. You can pack what clothes you need and I will see that the other things are sent on at your request. You say that you never have cared for college, but I am sure you prefer to leave it honorably rather than in disgrace. Will you think it over to-night and let me know your decision in the morning? If you do not come down to breakfast I shall know you have decided to do as I suggest, and I promise you, under those conditions I shall never say a word to any one about the affair. I hope you'll do the right thing. Good night."
