"He is!" answered Bert. "But can I get him back again? Oh, I must get him!" and he looked about for some way to do this. "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. Mr. Bobbsey then went to the door of the baggage car, and, leaning out, whistled in a way Snap well knew. He could see the dog, back on the depot platform, "wagging tails" with another dog. "Here, Snap! Snap!" called Mr. Bobbsey, as the train slowly came to a stop. "Here Snap!" Bert leaned out beside his father, and also whistled and called. Then Snap knew he had done wrong to jump out, and back he came, racing as hard as he could. "I'll open the end door of the car if you wish, so he can come up the steps," offered the brakeman. "You don't need to, thank you," replied Mr. Bobbsey. "I guess Snap can jump up here, though it is pretty high." By this time a number of persons from the train had either gotten out, or thrust their heads from the windows, to learn the reason for the sudden stop. But when they saw the dog they understood. "Up, Snap! Up!" called Mr. Bobbsey, as the children's pet came leaping along beside the track. Snap gave one look up at the high sill of the baggage car door, and then, with a loud bark, he gave a great leap and landed right beside Bert. "Say, that dog's a fine jumper!" cried several railroad men who had come up to see what the trouble was.
