d turn it's sure to
make you feel good--that you did it--see? But if you do it just for your
own pleasure, then it's not a good turn. But Roy puts over a lot of
nonsense about good turns. He does it just to make me mad--because I've
made a sort of study of them--like."

Mary laughed in spite of herself.

"He says it was a good thing when Tom threw a barrel stave in the
Chinese laundry because it led to his being a scout. But that isn't
logic. Do you know what logic is?"

Mary thought she had a notion of what it was.

"A thing that's bad can't be good, can it?" Pee-wee persisted. "Suppose
you should hit me with a brick----"

"I wouldn't think of doing such a thing!"

"But suppose you did. And suppose the scouts came along and gave me
first aid and after that I became a scout. Could you say you did me a
good turn by hitting me with a brick because that way I got to be a
scout? Roy--you got to be careful with him--you can't always tell when
he's jollying."

Mary looked at him intently for a few seconds. "Well, then," said she,
"since you've made a study of good turns tell me this. If Roy and Tom
were to ask you to go with them on their long hike, would that be a good
turn?"

"Sure it would, because it would have a sacrifice in it, don't you see?"

"How?"

"Because they'd do it just to please me--they wouldn't really want me."

"Well," she laughed, "Roy's good at making sacrifices."

"Je-ru-salem!" said Pee-wee, shaking his head almost incredulously at
the idea of such good fortune; "that'll be some trip. But you know what
they say, and it's true--I got to admit it's true--that two's a company,
three's a crowd."

"It wouldn't be three," laughed Mary; "it would only be two and a half."

She watched the sturdy figure as Pee-wee trudged along the gravel walk
and down the street. He seemed even smaller than he had seemed on the
veranda. And it was borne in upon her how much jollying he stood for and
how many good things he missed just because he _was_ little, and how
cheerful and generous-hearted he was withal.

The next morning Roy received a letter which read:

"Dear Roy--I want you and Tom to ask Walter Harris to go with you.
Please don't tell him that I asked you. You said you were going to name
one of the cabins or one of the boats for me because I took so much
interest. I'd rather have you do this. You can call it a good turn if
you want to--a real one.

"MARY TEMPLE."

Pee-wee Harris also received
