"Chain six, double crochet—into the ring—" Betty murmured her directions half aloud.

"Right here, Ma'am?" The porter's voice aroused her.

There in the aisle stood the girl she had noticed in the diner, and with her was a harassed looking porter carrying three heavy bags.

"Perhaps you would just as lief take the aisle seat?" said the girl, surveying Betty as a princess might gaze upon an annoying little page. "I travel better when I can have plenty of fresh air."

"You might have thought I was a bug," Betty confided later to Bob.

The diamonds flashed as the girl loosened the fur collar at her throat.

"Please move over," she commanded calmly.

Betty was bewildered, but her innate courtesy died hard.

"You—you've made a mistake," she faltered. "This seat is taken."

"The conductor said to take any vacant seat," said the newcomer. "You can't hold seats in a public conveyance—my father says so. Put the bags in here, porter. Be careful of that enamel leather."
