"What is an adverb?"

Ruby looked up at her teacher, and was just about to answer, when her eyes rested upon the place where the curl ought to have been. Miss Ketchum's hair was very thin just there, and the contrast between the round curl on one side of her head and the empty place upon the other was so funny that before Ruby thought of what she was doing she had laughed aloud.

Miss Ketchum had not the least idea that there was anything in her appearance which could be amusing, and as she had often been tried by mischievous scholars giggling or whispering, she thought that Ruby was deliberately intending to be rude, and very naturally she was much provoked at her. One could hardly have expected her to think anything else, for it was not very pleasant to have one of her scholars look straight at her and then burst out laughing.

Poor Miss Ketchum's face grew as red as Ruby's own, and she said very sternly,—

"I am surprised at you, Ruby. I did not know that you could behave so badly. You may carry your grammar over there in the corner, and sit there facing the school the rest of the day. Next, what is an adverb?"

Poor Ruby was too miserable to try to explain, and she did n't like to tell Miss Ketchum that she had left her curl off; so she took her book and went over in the corner, feeling completely in disgrace.

After a while the door opened, and Aunt Emma looked in, to call one of her pupils for her music lesson, and the look of grave surprise upon her face when she saw Ruby sitting there by herself made the little girl more miserable than ever. She had not meant to laugh. If she had noticed the missing curl before she came to the class she never would have laughed; but seeing it suddenly drove the adverb quite out of her head, and before she had known what she was about she had laughed.

It seemed a long time to recess, and it was all that Ruby could do to keep the tears out of her eyes. It was the first time in her life that she had ever been in disgrace at school, and she felt it keenly. It would have been bad enough if it had happened in school at home, but to have it happen here was doubly hard.

Ruby was sure she could never be happy here again, never, after having to stay up there all the morning in disgrace before the whole school.

At last the recess-bell rang, and the other scholars went out to play, and Ruby and Miss Ketchum were left alone.
