I wish you would see Flossie and Freddie. Come here, Bert and Nan. This is my friend, Mr. Martin," he continued, "and these are his children, Billy and Nell. They live in Washington, D. C."
So that was what Mr. Bobbsey meant. At first, Nan said afterward, she had a little notion that her father might have meant the boy and girl were the children of General George Washington. But a moment's thought told Nan that this could not be. General Washington's children, supposing him to have had any, would have been grown up into old men and women and would have passed away long ago. But Billy and Nell Martin lived in Washington, District of Columbia (which is what the letters D. C. stand for) and, Bert and Nan knew, Washington was the capital, or chief city, of the United States.
"Mr. Martin came in to see me on business," explained Daddy Bobbsey. "He is traveling for a lumber firm, and on this trip he brought his boy and girl with him."
"They aren't twins, though," said Mr. Martin with a nod at Nan and Bert.
