Now the cars were rolling on again, and, in a little while the conductor again came back to where Mrs. Brown was sitting.
"Now where's the little boy who stopped my train?" he asked with a smile.
"I'm here," Bunny answered, "and this is my sister Sue."
"Well, I'm glad to meet you both again, I'm sure," and the conductor shook hands with Bunny and kissed Sue. "Now, if you two would like it, I'll show you where you blew the whistle in the engine."
"Oh, will you take us in the engine?" asked Bunny, who had always wanted to go in that funny little house on top of the locomotive's back.
"Yes, I'll take you in when we make the next stop," the conductor said. "We have to wait a few minutes to give the engine a drink of water, and I'll take you and your sister in the engine. That is if you say it's all right," and he turned around to look at Mrs. Brown.
"Oh, yes," Bunny's mother answered. "They may go with you if they won't be a bother. I'm sorry my little boy made so much trouble about stopping the train."
"Oh, well, he didn't mean to, so we'll forget all about it. I'll come back and get you when we stop," he said.
A little later the train slowed up. It did it so easily that no one fell out of his seat this time, and, pretty soon, back came the conductor to get Bunny and Sue.
The engine had stopped near a big wooden tank filled with water, and some of this water was running through a big pipe into the tender of the engine. The tender is the place where the coal is kept for the locomotive fire.
