"You'll have to answer that one yourself, Laddie," said Daddy Bunker, laughing.

"When he's a runner," Laddie said promptly. "Isn't that a good riddle?"

"And he juggles dishes almost as good as that juggler we saw at the show," Russ declared.

"He must have almost as much skill as a juggler to serve his customers in this car," said Mrs. Bunker, watching the man coming down the aisle as the train sped around a sharp curve.

"Oh! Look there!" cried Rose, who was likewise facing the right way to see the waiter's approach.

The smiling black man was coming with a soup toureen balanced on one hand while he had other dishes on a tray balanced on his other hand. The car swayed so that the waiter began to stagger as though he were on the deck of a ship in a heavy sea.

"Oh! He's going!" sang out Russ.

The waiter jerked to one side, and almost dropped the soup toureen. Then he pitched the other way and his tray hit against one of the diners at another table.

"Look out what you're doing!" cried the man whom the tray had struck.

"Yes, sah! Yes, sah!" panted the waiter, and he tried to balance his tray.
