Mrs. Brown was suddenly awakened from her sleep. She, too, had almost slid from her seat when the car stopped so suddenly. For the moment Bunny pulled down on the cord, it blew a whistle in the cab, or little house of the engine, where the engineer sits. And when the engineer heard that whistle he knew it meant for him to stop as soon as he could.

He could look down the track, and see that there was nothing on the rails that he could hit, but, hearing the whistle, he thought the conductor, or one of the brakemen, must have pulled the cord. Perhaps the engineer thought some one had fallen off the train, as people sometimes fall off boats, and the engineer wanted to stop quickly so the passenger could be picked up. At any rate, he stopped very suddenly, and that was what made all the trouble. Or, rather, Bunny Brown made all the trouble, though he did not mean to.

"Why, Bunny!" cried his mother, as she straightened up in her seat. "Where are you? Where is Sue? What has happened?"

For, you know, Bunny and Sue had slid down to the floor of the car when the train came to such a sudden stop.

"Where are you, children?" called Mrs. Brown, anxiously.

"I—I'm here, Mother!" answered Sue. "Bunny pushed me off my seat!"

"Oh-o-o-o, Sue Brown! I did not!" cried the little fellow, getting up with the parasol still in his hand. "I did not!"

"Well, you made the train stop, and that knocked me out of my seat, and my doll was knocked down too, so there!" answered Sue, and she seemed ready to cry.

"Bunny, what happened? What did you do?" asked his mother. "What are you doing with my parasol?" she asked.

"I—I just reached up to pull down that rope with the crooked handle end," Bunny answered, pointing to the whistle cord. "I wanted to show Sue how strong it was, so I pulled on it."
