It rests him after studying so hard, she says.

If you don't like the pillow, I could do that for you, 'cause you look as if you were more tired of studying than Will," said Maud, with some hesitation, but an evident desire to be useful and agreeable.
"Well, I don't care if you do try it, for I am confoundedly tired." And Tom laughed, as he recalled the frolic he had been on the night before.
Maud established herself with great satisfaction, and Tom owned that a silk apron was nicer than a fuzzy cushion.
"Do you like it ?" she asked, after a few strokes over the hot forehead, which she thought was fevered by intense application to Greek and Latin.
"Not bad; play away," was the gracious reply, as Tom shut his eyes, and lay so still that Maud was charmed at the success of her attempt.
Presently, she said, softly, "Tom, are you asleep ?" "Just turning the corner." "Before you get quite round would you please tell me what a Public Admonition is ?" "What do you want to know for ?" demanded Tom, opening his eyes very wide.
"I heard Will talking about Publics and Privates, and I meant to ask him, but I forgot." "What did he say ?" "I don't remember; it was about somebody who cut prayers, and got a Private, and had done all sorts of bad things, and had one or two Publics.

I did n't hear the name and did n't care; I only wanted to know what the words meant." "So Will tells tales, does he ?" and Tom's forehead wrinkled with a frown.
"No, he did n't; Polly knew about it and asked him." "Will's a 'dig,'" growled Tom, shutting his eyes again, as if nothing more could be said of the delinquent William.
"I don't care if he is; I like him very much, and so does Polly." "Happy Fresh!" said Tom, with a comical groan.
"You need n't sniff at him, for he is nice, and treats me with respect," cried Maud, with an energy that made Tom laugh in her face.
"He 's good to Polly always, and puts on her cloak for her, and says 'my dear,' and kisses her 'good-night,' and don't think it 's silly, and I wish I had a brother just like him, yes, I do!" And Maud showed signs of woe, for her disappointment about going was very great.
"Bless my boots! what's the chicken ruffling up her little feathers and pecking at me for?
Is that the way Polly soothes the best of brothers ?" said Tom, still laughing.
"Oh, I forgot! there, I won't cry; but I do want to go," and Maud swallowed her tears, and began to stroke again.
Now Tom's horse and sleigh were in the stable, for he meant to drive out to College that evening, but he did n't take Maud's hint.

It was less trouble to lie still, and say in a conciliatory tone, "Tell me some more about this good boy, it 's very interesting." "No, I shan't, but I 'll tell about Puttel's playing on the piano," said Maud, anxious to efface the memory of her momentary weakness.

"Polly points to the right key with a little stick, and Puttel sits on the stool and pats each key as it 's touched, and it makes a tune.
