St. Valentine's Day was now close at hand, and all of the children of the neighborhood were saving their money with which to buy valentines.  
"I know just the ones I am going to get," said Nan.
 
"I want some big red hearts," put in Freddie. "Just love hearts, I do!"
 
"I want the kind you can look into," came from Flossie. "Don't you know, the kind that fold up?"
 
Two days before St. Valentine's Day the children gathered around the sitting-room¹ table and began to make valentines. They had paper of various colors and pictures cut from old magazines. They worked very hard, and some of the valentines thus manufactured were as good as many that could be bought.
"Oh, I saw just the valentine for Freddie," whispered Nan to Bert. "It had a fireman running to a fire on it."
 
There were a great many mysterious little packages brought into the house on the afternoon before St. Valentine's Day, and Mr. Bobbsey had to supply quite a few postage stamps.
 
"My, my, but the postman will have a lot to do to-morrow," said Mr. Bobbsey. "If this keeps on he'll want his wages increased, I am afraid."
 
The fun began early in the morning. On coming down to breakfast each of the children found a valentine under his or her plate. They were all very pretty.
 
"Where in the world did they come from?" cried Nan. "Oh, mamma, did you put them there?"
 
"No, Nan," said Mrs. Bobbsey.
 
"Then it must have been Dinah!" said Nan, and rushed into the kitchen. "Oh, Dinah, how good of you!"
 
"'Spect da is from St. Valentine," said the cook, smiling broadly.
 
"Oh, I know you!" said Nan.
 
"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 soberly².
 
"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 cloak⁴, 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 verses⁵. 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.
 
"I sent out two more than I received," said Bert.
 
"Never mind, Bert; boys don't expect so many as girls," answered Nan.
 
"I'd like to know who sent that mean thing that was marked ghost," went on her twin brother.
 
"It must have come from Danny Rugg," said Bert, and he was right. It had come from Danny, but Nan never let him know that she had received it, so his hoped-for fun over it was spoilt.
 
In the evening there was more fun than ever. All of the children went out and dropped valentines on the front piazzas⁶ of their friends' houses. As soon as a valentine was dropped the door bell would be given a sharp ring, and then everybody would run and hide and watch to see who came to the door.
 
When the Bobbsey children went home they saw somebody on their own front piazza⁷. It was a boy and he was on his knees, placing something under the door mat.
 
"I really believe it is Danny Rugg!" cried N............
