"But it's a vestibule train, papa," said the boy. "It's like one big car. I can't fall off."
"Well, I don't know," said Mr. Bobbsey, slowly.
"I'll take him up front, if he wants to see about the dog," said a brakeman who had heard Bert's talk.
"Oh, thank you," said Mr. Bobbsey. "Be careful, Bert."
But, as it turned out, there was no danger at all. As Bert had said, the cars were joined together with "vestibules," that made the train like one big railway coach. And as it was slowing up to stop at a station, when Bert went forward to the baggage car, he had no trouble at all in walking along with the brake-man.
Bert found Snap very glad indeed to see him, and as the train was then at a standstill the boy took the chain off the dog's collar, and let him run about the car a little, for he had to be kept chained fast while the cars were in motion.
"I guess you want to run about a bit, eh, Snap?" said Bert.
"Bow wow!" barked the dog, and that was the best answer he could make. The man in the baggage car had seen to it that Snap had plenty of water to drink, for the day was very hot.
"Better chain him up again, my boy," suggested the baggage man, after a bit. "We'll start pretty soon now."
Bert led Snap over to the side of the car, where the collar-chain dangled, but, just then, Snap, looking out of the door of the baggage car, saw a strange dog on the depot platform. Whether Snap knew this dog, or thought he did, Bert could not tell.
