lazy chap?"

"A companion--that's all," replied her sister. "I think Ida is
about as unenergetic a girl as I ever knew."

"Funny thing," said Cora, speaking loudly enough to be heard above
the noise of the motor, "how she manages to keep going. She rides as
often in Sid's car as if--well, as if she was his own sister."

"Oftener than most sisters," added Belle significantly.

"They have just left her friend, who was on from New City, at the
depot," said Bess. "It's quite handy to have a chum with a
motor-car--even if it does happen to be a chap like Sid."

"Well, I guess Ida's harmless, even if she is jealous," said Cora.
"I do believe that's all that ails Ida--just plain jealousy."

"Maybe," assented Isabel.

They rode along for some time, coasting down the steeper parts of
the hill, and running easily where there was a level stretch. They
were now approaching the worst part of the descent. From this point
there was quite a steep slant to the level highway, which the
railroad crossed at grade, and approached on a curve.

There was a long-drawn, shrill whistle.

"What's that?" exclaimed Elizabeth.
