As the door opened, Bert and Nan saw a strange man talking to Mr.
Bobbsey. But what interested them more than this was the sight of two
children--a boy and a girl about their own age--in their father's
private office. The boy and girl were sitting on chairs, looking at the
very same lumber books--those with pictures of big woods in them--that
Nan and Bert often looked at themselves.

Mr. Bobbsey glanced up as the door opened. He saw his two older twins,
and, smiling at them, said:

"Come in, Nan and Bert. I want you to meet these Washington children!"



CHAPTER IV

MISS POMPRET'S CHINA

Bert and Nan looked at one another in some surprise as they stood in the
door of their father's private office. What did he mean by saying that
they were to come in and meet the "Washington children?" Who were the
"Washington children?"

Nan and Bert were soon to know, for their father spoke again.

"Come on in. These are two of my twins, Mr. Martin," he added to the
gentleman who was sitting near his desk. The two "Washington children,"
looked up from the lumber books they had been reading. No, I am wrong,
they had not been reading them--only looking at the pictures.
