"Come on, Bert, if you're coming!" called Charley Mason, from the street in front of the Bobbsey home. "It's a terrible wreck—cars off the track—engines all smashed up—everything!"

"Here, Nan, you take Flossie and Freddie into the house! I'm going with Charley!" said Bert.

"I want to see the wreck, too!" objected Nan. "You go into the house,
Freddie, and I'll bring you a lollypop when I come back," she added.
"Don't want a lollypop! I want to see the busted engines!" declared
Freddie almost ready to cry.

"So do I!" chimed in Flossie. She generally did want to see the same things Freddie saw.

"Oh, dear! what shall we do?" exclaimed Nan.

Just then, from the door, Mrs. Bobbsey called:

"Children, children, what's the matter? What was that loud noise that seemed to shake the house?"

"It's a train wreck and I want to go down with Charley Mason to see it!" answered Bert. "But Flossie and Freddie want to come, and they're too little and—and—"

Then Flossie and Freddie began to talk, and so did Nan and so did Charley, and there was so much talking that I will wait a few minutes for every one to get quiet, and then go on with the story. And, while I am waiting, I will tell my new readers something about the Bobbsey twins as they have been written about in the books that come before this one in the series.

The four children lived in the eastern city of Lakeport, at the head of Lake Metoka. Mr. Bobbsey was in the lumber business, and boats on the lake in summer and trains on the railroad in winter brought piles of boards to his yard.
