"good-bye," and while the father of the Washington children again asked
Mr. and Mrs. Bobbsey to come to visit him at his home, Nell and Billy
whispered to Nan and Bert:

"Be sure and come, and bring Flossie and Freddie with you!"

"We will!" promised Nan, but neither she nor Bert guessed what a queer
little adventure they were soon to have in Washington.

A few days later school opened, and the Bobbsey twins had to go back to
their class-rooms. At first they did not like it, after the long, joyous
vacation on the deep, blue sea, but their teachers were kind, and
finally the twins began to feel that, after all, school was not such a
bad place.

Thanksgiving Day came, bringing a little vacation period, and after
church in the morning, the Bobbsey twins went home to eat roast turkey
and cranberry sauce. Then they went out to play with some of their boy
and girl friends, having lots of fun in the barn and yard.

"But don't slide any more hay down on Flossie and Freddie!" begged Mrs.
Bobbsey.

"We won't!" promised Bert and Nan, and they kept their word.

It was about a week after Thanksgiving, and Bert and Nan were on their
way home from school one day, when, as they passed a red brick house on
the street next to theirs, they saw, standing on the porch, a pleasant-
faced, elderly lady who was looking up and down the avenue.
