"Your papers on mathematics are quite hopeless," he continued, growing more querulous because his pity was aroused. "It's out of the question that you should write. I've done my best to show you that you should give less time to English subjects and devote more to Algebra and your Euclid." He arose and blustered up and down the room.

"You haven't a mathematical head," he was saying for the third time when a sharp rap upon the door interrupted. Dr. Primrose, looking very much relieved, opened it. Miss Gordon turned away to the window to hide the rising tears.

There was a short, hurried conversation at the door, and the teacher turned to his victim. He had a big, warm heart that was vastly relieved at the prospect of escape from a most unpleasant duty.

"Ah, Miss Gordon," he said briskly. "Here are two gentlemen to see you. You have permission to go home early this afternoon, by special request. Kindly bear in mind what I have told you."

He stepped quickly aside, and ushered in two tall, young men, at the same time closing the door behind him.

At the same instant all Miss Gordon's troubles were shut out with him, and her face lit up with rapturous delight. She skipped across the room with a joyful scream.

"Oh, John, John Gordon, you dear old sneak; why didn't you tell me you were coming to-day?"

She flung her arms about his neck and gave him a sounding kiss. John Gordon had been a whole year in college, but he had not yet become sufficiently grown-up to accept a salute from his sister. He drew back rather embarrassed, but his blue eyes shone in his dark face. He was tremendously glad to see Lizzie again, and could not quite hide the fact.

The other young man seemed equally pleased. "I say, Lizzie!" he exclaimed, as she joyously shook both his hands. "You're grown about a yard. And her neck's longer than ever, isn't it, John?"

"You mean old Pretender," she said with a pout; nevertheless, she did not look offended. Miss Gordon had quite changed her views regarding the possession of a long neck. Estella Raymond, her dearest chum, who was short and plump, had declared many times that she would give ten thousand dollars—not specifying how she was to come by such a sum—if she could have a neck one-half as long and slim and graceful as Beth Gordon's.
