Nevertheless her friend did not yet require her aid. Although at Jean's surprising words Jacqueline Ralston had turned pale, she was perhaps not more so than Ruth and the other two girls. However, she was evidently doing her best to hold on to her self-control and not to allow the moment's bewilderment and fright to overwhelm her.

"No, Frieda did not come on the ship with us the second time, Ruth," she explained, turning quietly toward their chaperon. "But please do not let us be alarmed. She must have come aboard by herself beforehand. For I can remember hearing her say her last good-by to Jim while I was still talking to Peter. Frieda is nearly seventeen; why, it is ridiculous to suppose that she would be so foolish as to let the steamer sail off without her! Besides, wasn't Jim right there! And isn't he always possessed of the idea that we will be late for things and that unknown catastrophes will overtake us? If necessary he would have put Frieda on board by main force. So let's go find her."

Very quickly, then, the little party of four turned from their former places. And Jean's face, which had been the gayest in the group at the beginning of this conversation, was now the most terrified.

"If Frieda Ralston isn't on board the Martha Washington with us, she most certainly is not on land with any of our friends," Jean insisted, "for I know that Frieda left them on the pier before I did. So if she isn't on this ship something dreadful must have happened to her; some one must have stolen her away. Oh, what on earth shall we do?"

Jean was following the others in such a complete state of panic that she hardly knew what she was saying. So at first she scarcely heard the low voice sounding close to her ears. Only one thought occupied her mind. Frieda was lost before they had fairly started on their journey. If she could not be found on the ship, what were they to do? Of course they could send Marconigrams back to Jim Colter and Ralph Merrit, who had come all the way from the ranch to New York City to say farewell to them. But if Frieda should happen not to be with them or with any of their other friends, must there not be days and days of horrible waiting and anxiety before they could return home? Each moment the great steamer was carrying them farther and farther away from the United States and not all the gold in the Rainbow Mine could persuade her to alter her course or to stop until they reached Gibraltar.

The voice spoke again. Evidently its owner must have pursued Ruth and the three girls.

"I am afraid you are in some difficulty. If my maid or courier can be of any service to you I shall be most happy. Evidently you have not crossed before."

This final suggestion, even in the midst of her anxiety, made Jean flush uncomfortably. Immediately she stopped and turned around, recognizing the young woman who had previously both attracted and annoyed her. Something in Jean's expression must have betrayed her irritation, for the stranger smiled again.

"I hope I haven't offended you," she apologized. "I only wished to be useful. You are in trouble, so you must let me try to serve you."

In their overwhelming anxiety Ruth, Olive and Jack had continued on the way to their staterooms, leaving Jean to answer for all of them. Now, to her chagrin, the tears began overflowing her eyes like a frightened baby's.
