“I’m not going to let him get away from us,” she cried.

But Bess seized her arm. “Oh, don’t! Let’s not have another quarrel with that Riggs girl right here.”

“Dear me! I haven’t quarreled with her at all, yet,” said Nan, somewhat amused.

“She’s—so—mean,” began Bess, when Nan interrupted:

“Well! we’ll just beat her to it at that!”

“Oh, how, Nan?”

“We’ll get there first.”

“But, how?” asked her chum again.

Several automobiles were standing beside the platform and Nan swiftly approached the driver of the nearest one.
