But the fourth girl, Miss Moore explained, by some accident had failed to arrive in time for the steamer. She was to have come from Charleston, South Carolina, having made her application and sent her credentials from there. It was foolish of her to have waited until the last hour before arriving in New York. Now her train had been delayed, and as her passage had been engaged, the money would simply have to be wasted. Had the Red Cross Society known beforehand, another nurse could have taken her place.

The next hour and a half was one of painful confusion. Surely so few passengers never before had so many friends to see them off. Farewells these days meant more than partings under ordinary circumstances. No matter what pretense might be made to the contrary, in every mind, deep in every heart was the possibility that a passenger steamer might strike a floating mine.

Of course, Barbara had been forced to say her hardest farewells before leaving her home in Nebraska. Nevertheless, she could not now help sharing Mildred’s emotions and those of her family. Besides, the Thorntons had been so kind to her in the past two weeks. Mrs. Thornton had apologized for blaming her for Mildred’s decision, but after all it was easy to understand her feeling in the matter. Judge Thornton was one of the biggest-hearted, dearest men in the world. Then there was Dick! Of course, he was a good-for-nothing fellow who would never amount to much except to be a spoiled darling all his days! Yet certainly he was attractive and had been wonderfully sweet-tempered and courteous to her.

Even this morning he had never allowed her to feel lonely for an instant. Always he saw that she was among the groups of their friends who were showering attentions upon Mildred—books and flowers and sweets, besides various extraordinary things which she was recommended to use in her work.

Dick’s farewell present Barbara thought a little curious. It was an extremely costly electric lamp mounted in silver to carry about in her pocket.

“It is to help you see your way, if you should ever get lost or have to go out at night while you are doing that plagued nursing,” he whispered just as the final whistles blew and the friends of the passengers were being put ashore.

As Dick ran down the gang-plank, both Mildred and Barbara were watching him with their eyes full of tears. Suddenly he had to step aside in order not to run over a girl hurrying up the plank from the shore. She was dressed in deep mourning; her hair was of the purest gold and her eyes brown. She had two boys with her, each one of them carrying an extraordinary looking old-fashioned carpet bag of a pattern of fifty years ago.

“I regret it if I have kept you waiting,” she said in a soft, drawling voice to one of the stewards who happened to be nearest the gang-plank. “I’ve come all the way from Charleston, South Carolina, and my train was four hours late.”

The tears driven away by curiosity, Mildred and Barbara now stared at each other. Was this the fourth girl who was to accompany them as a Red Cross nurse? She looked less like a nurse than any one of them. Why, she was as fragile as possible herself, and evidently had never been away from home before in her life. Now she was under the impression that the steamer had been kept waiting for her. Certainly she was apologizing to the steward for delaying them.

Yet a glance at their older companion and both girls felt a warm companionship for the newcomer. For if Miss Peabody had been discouraged on being introduced to them, it was nothing to the disfavor she now allowed herself to show at the appearance of the fourth member of their little Red Cross band.
