“Oh!  Oh!” exclaimed Bert.

“Hush!” said the old man softly.  “Don’t awaken her.  When she arouses I’ll tell you how she came in here.  It’s quite a joke!”

“You stay here, Bert,” said Mr. Bobbsey to his son, “and I’ll go and get your mother, Nan and Freddie.  I want them to see how cute Flossie looks.  They’ll be glad to know we have found her.”

So while Bert sat in a chair in the old man’s office Mr. Bobbsey hurried to tell his wife and the others the good news.  And soon Mrs. Bobbsey and the rest of the children were peeping at Flossie as she lay asleep.

And then, suddenly, as they were all looking down at her, the little girl opened her eyes.  She saw her mother and father; she saw Nan and Bert and Freddie; and then she looked at the kind old man with the white hair.

“Did you find a story book for me?” were the first words Flossie said.

“Well, I’m afraid not, my dear,” was the old man’s answer.  “We don’t have story books for little girls up here, though there may be some downstairs.”

“Is that what she came in here for—­a story book?” asked Mr. Bobbsey.

“I believe it was,” answered the old man, with a smile.  “I was busy at my desk when I heard the patter of little feet and a little girl’s voice asking me for a story book.  I looked around, and there stood your little one.  I guessed, at once, that she must have wandered away from some visitors in the library, so I gave her a cake I happened to have in my lunch box, and got her to lie down on the sofa, as I saw she was tired.  Then she fell asleep, and I covered her up and put the screen around her.  I knew some one would come for her.”

“Thank you, so much!” exclaimed Mrs. Bobbsey.  “But, Flossie, how did you happen to come up here?”

“Oh, I wanted a story book,” explained the little girl, as she sat up.  “We have story books in our library, an’ there ought to be story books here.  I looked in this room an’ I saw a lot of books, so I did ask for one with a story in it.  I like a story about pigs an’ bears an’—­an’ everything!” finished Flossie.

“Well, I wish I had that kind of story book for you, but I haven’t!” laughed the old man.

“All my books are very dull, indeed, for children, though when you grow up you may like to read them,” and he waved his hand at the many books in the room.

So Flossie was lost and found again.  The old man was one of the librarians, and he had taken good care of the little girl until her family came for her.  After thanking him, Mr. and Mrs. Bobbsey led their twins downstairs and Mr. Bobbsey said: 

“Well, I think we have seen enough of the library for a time.  We had better go and see the Martins.”

“Oh, yes!” cried Bert.  “Billy said he’d take me to see the President.”

“And I want to go, too!” added Nan.

“We’ll see!” half promised her mother.

In an automobile the Bobbsey family rode to where the Martin family lived.  And you can well believe that Billy and Nell were glad to see the Bobbsey twins once more.  Mrs. Martin welcomed Mrs. Bobbsey, and soon there was a happy reunion.  Mr. Martin was at his office, and Mr. Bobbsey said he would go down there to see him.
