" Bunny answered. "I was pulling down on the rope, to
show my sister how strong it was."

"Oh, I see," the conductor went on. "Then you didn't stop my train
because you wanted to get off?"

"Oh, no!" cried Bunny quickly. "I don't want to get off now. I want to
go to New York. We're going to my Aunt Lu's house."

"Well, New York is quite a way off yet," laughed the conductor, "so I
guess you had better stay with us. But please don't pull on the whistle
cord again."

"I won't," Bunny promised. "But it is a strong rope, isn't it, Mr.
Conductor? And it does hold the cars together; doesn't it?"

"Well, no, not exactly," the conductor answered, while the passengers
laughed. "I'll show you what the cord does in a little while. But I'm
glad nothing has happened. I thought there was an accident when the
train stopped so quickly, so I ran through all the cars to find out. Now
we'll go on again."

He reached up and pulled the car-cord twice. Far up ahead, in the cab of
the locomotive, a little whistle blew twice, and the engineer knew that
meant for him to go ahead. It's just like that on a trolley car. One
bell means to stop, and two bells to go ahead.

"Oh Bunny! Why did you do it?" asked his mother, as she took the parasol

Mrs. Brown thought there was not much need of scolding Bunny, for he had
not meant to do wrong. He promised never again to pull on a whistle cord
in a train.

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 mu
