Margy was in the seat with her mother, playing with one of the Japanese
dolls that had come ashore on the beach at Cousin Tom's, as I have told
you in the book just before this one.

"My doll wants a drink," suddenly announced the little girl. "She's
awful thirsty."

"You probably mean you are," laughed her mother. "Rose, will you take
Margy to the water tank and get her a drink? Be careful, and hold on to
the arms of the seats so you don't fall down. It isn't far."

"I wants a drink, too," announced Mun Bun. "I'm going to drink it
myself, too," he announced, "and not give it to any doll."

"Well, Rose can take both of you," said Mrs. Bunker. Rose was a real
"mother's helper," and often looked after the two smaller children in
such things as getting them drinks of water. The tank was at the end of
the car, not far from where the Bunkers were sitting.

Mr. Bunker bought a picture book for Laddie, from the train boy who came
through the car every half hour or so, and the little riddle-chap curled
up in his seat to look at this.

Russ, with some bits of string, some little sticks he had in his pocket
and some paper, was making "something," though just what it was not even
he seemed to know. Violet got in the seat with Laddie to look at his
picture book. At the same time she may have been thinking up more
questions to ask, for all I know.
