Billy and Nell a good time. This is the first time I have ever taken them on a trip with me."
"And we've had such a lovely time!" exclaimed Nell.
'Tacks of fun!" added her brother.
"I'm sorry we can't stay longer," went on Mr. Martin. "You folk must come to Washington some day."
"Yes, I expect to," said Mr. Bobbsey. "I've been counting on going there some day on some business matters."
"Well, when you come be sure to bring the children," said the father of Nell and Billy. "I think they would enjoy seeing the White House, the big Capitol building, the Congressional Library, Washington's home at Mt. Vernon and places like that."
"Could we see the Washington Monument?" asked Nan. She remembered looking at a picture of that in her geography.
"Oh, yes, I'd show you that, too," said Mr. Martin.
"And could we see the Potomac River?" Bert wanted to know.
