"Nan!" cried Bess, looking uneasily over her shoulder, "what a terrible thing. But, of course, it's only imagination," she added easily, for it was instinct with Bess to cast aside anything that threatened to worry her or interfere with her fun. "I told you the old papers were getting on your nerves."

"You're right," said Nan, with a little sigh as she rose to take off her coat and hat and straighten her hair before the tiny mirror. "They certainly are getting on my nerves."

"Well, for goodness' sake get them off then," commanded Bess, bouncing impatiently on a berth. "I never saw such a girl to take everybody else's troubles on her own shoulders. I'll be glad when you turn the papers over to Mr. Mason."

Nan smiled a resigned little smile at her reflection in the mirror. Then she came over and put an arm about her pouting chum.

"All right," she promised gaily, "I won't ever do it again. Only come on and smile, honey. If you knew how pretty you look when you do, you would never do anything else."

There are very few girls who can withstand an appeal like that, and Bess was not one of them. A smile replaced the frown immediately and the next minute she was chatting merrily about their crowded little stateroom and the two narrow berths, one above the other, wondering with a grimace whether they would be seasick or not, and so, on and on, till Nan's momentary depression forsook her and she felt again the thrill that had quickened her blood as they had stood on the dock, gazing out over the harbor.

Yet, almost unknown to Nan herself, there lingered in the back of her mind a strange, uneasy premonition of trouble to come, and again and again her eyes sought the spot where the bag with Mrs. Bragley's papers stowed safely inside lay hidden.

"I wonder which one of us is going to take the upper berth," Bess chattered gaily on. "You had better, Nan, because you're thinner than I. And then if the berth should cave in it wouldn't hurt you so much because there would be something soft to fall on. It's a snug little place, isn't it?"

"Snug is right," said Nan, with a giggle. "You can't turn around without running in to something."

"That's Linda's fault. She shouldn't have wrecked the heating system at school in the Palm Beach season. If it had been in December now, or March, there wouldn't have been such a crowd and we could have had a real honest to goodness stateroom, instead of this two-by-one hole in the wall."
