"Anyway," he declared, "this game's not 'in fun.' You said you'd play
'for fair' and that means 'for keeps.'"

Jehosophat was silent. He hadn't understood what 'for fair' had meant
at all. Still, he had agreed to play that way, and so, though he
wanted to punch Fatty's head for him, he supposed he'd have to take
his losses like a gentleman.

But now Fatty was taking something out of his pocket, something made
of wood and shaped like a bridge or a saw with teeth in it. He placed
it on the ground.

"Your turn, Joshy," he said.

"What'll I do?" asked Jehosophat.

"Just roll your marbles under this bridge, and if they go through the
little holes, you can keep 'em. If they don't, they're mine."

The two boys didn't see through the trick, and very foolishly they
thought they might win some of their beautiful marbles back.

So they rolled marble after marble against that little wooden bridge.
But it was much harder to aim straight than they had expected. More
marbles would hit against the wood and bounce back than ever went
through the little holes. And when this strange new game was ended
Fatty had fifty-two marbles and they each had four!

Then Fatty walked off.
