"It's just lubby!" cried Freddie, breaking out into his baby talk. "Just lubby, Dinah! Such a big red heart, too!"

The postman came just before it was time to start for school. He brought six valentines, three for Flossie, two for Freddie and one for Bert.

"Oh, Nan, where is yours?" cried Bert.

"I—I guess he forgot me," said Nan rather soberly.

"Oh, he has made some mistake," said Bert and ran after the letter man. But it was of no use—all the mail for the Bobbseys had been delivered.

"Never mind, he'll come again this afternoon," said Mrs. Bobbsey, who saw how keenly Nan was disappointed.

On her desk in school Nan found two valentines from her schoolmates. One was very pretty, but the other was home-made and represented a girl running away from a figure labeled ghost. Nan put this out of sight as soon as she saw it.

All that day valentines were being delivered in various ways. Freddie found one in his cap, and Bert one between the leaves of his geography. Flossie found one pinned to her cloak, and Nan received another in a pasteboard box labeled Breakfast Food. This last was made of paper roses and was very pretty.

The letter man came that afternoon just as they arrived home from school. This time he had three valentines for Nan and several for the others. Some were comical, but the most of them were beautiful and contained very tender verses. There was much guessing as to who had sent each.

"I have received just as many as I sent out," said Nan, counting them over.
