“You'd better hurry up your apple, for if it is n't done pretty soon, you 'll have to leave it, Pug,” said Tom, looking annoyed.

“How is Fan?” asked Polly, with tact.

“Well, Fan is rather under the weather; says she's dyspeptic, which means cross.”

“She is cross, but she's sick too, for I found her crying one day, and she said nobody cared about her, and she might as well be dead,” added Maud, having turned her apple with tender care.

“We must try to cheer her up, among us. If I was n't so busy I'd like to devote myself to her, she has done so much for me,” said Polly, gratefully.

“I wish you could. I can't understand her, for she acts like a weathercock, and I never know how I'm going to find her. I hate to have her mope so, but, upon my life, I don't know what to do,” said Tom; but as he uttered the words, something was suggested by the sight before him. Chairs were few, and Polly had taken half of Will's when they drew round the fire. Now she was leaning against him, in a cosy, confiding way, delightful to behold, while Will's strong arm went round her with a protecting air, which said, as plainly as any words, that this big brother and small sister knew how to love and help one another. It was a pleasant little picture, all the pleasanter for its unconsciousness, and Tom found it both suggestive and agreeable.

“Poor old Fan, she don't get much petting; maybe that's what she wants. I 'll try it and see, for she stands by me like a trump. If she was a rosy, cosy little woman, like Polly, it would come easier, though,” thought Tom, as he meditatively ate his last nut, feeling that fraternal affection could not be very difficult of demonstration, to brothers blessed with pretty, good-tempered sisters.

“I told Tom about the bad fellow who blew up the professor, and he said he knew him, slightly; and I was so relieved, because I had a kind of a feeling that it was Tom himself, you and Will laughed so about it.”

Maud had a queer way of going on with her own thoughts, and suddenly coming out with whatever lay uppermost, regardless of time, place, or company. As this remark fell from her, there was a general smile, and Polly said, with mock solemnity, “It was a sad thing, and I've no doubt that misguided young man is very sorry for it now.”

“He looked perfectly bowed down with remorse last time I saw him,” said Will, regarding Tom with eyes full of fun, for Will was a boy as well as a bookworm, and relished a joke as well as scatter-brained Tom.
