"Don't jump out, whatever you do!" warned the brakeman who had brought Bert to the baggage car. The man stood in front of the open door, out of which trunks were taken. But Bert had no idea of doing what Snap had done. Besides, the train was moving quite rapidly now.
"Oh, how can I get my dog back?" Bert wanted to know.
"You can telegraph back, from the next station we stop at, and have the agent there send him on, wherever you are going," explained the baggage man.
"Oh, but we're going a long way," Bert said. "I'm afraid Snap would be lost, traveling alone. Oh, what will Nan say!"
Nan was as fond of Snap as was Bert himself, though perhaps the smaller twins, Flossie and Freddie cared more for Snoop, the black cat. But of course they loved Snap very much.
Poor Bert did not know what to do. Just then his father came running into the car.
"Did Snap get away?" cried Mr. Bobbsey. "Your mother saw a dog on the station platform that looked like him," went on the lumber man to Bert. "Is Snap—"
"He's gone!" interrupted Bert. "He jumped out of the car just now, and—"
"We must stop the train!" Mr. Bobbsey explained.
"All right, I guess we can make up any time we lose," the brakeman said. He reached up and pulled the cord that ran overhead in the car. There was a hissing of air, the locomotive whistle blew sharply, and the train came slowly to a stop. The brakeman had pulled an air whistle in the engine cab, and the engineer, hearing it, and knowing the train ought to stop, had turned off the steam.
