"Can you put a hand on my shoulder?" gasped Betty, beginning to feel the tremendous effort she had made. "Hang on to me, Honey, and we'll get out of this all right."

Amy clutched her shoulder, and slowly the Little Captain turned about, saving her strength for the long swim back. She could not be too long about it either, she thought desperately. Amy was almost exhausted and had all she could do to keep her head above the water.

It all depended on her, Betty. If she could get to shore, carrying the double weight before Amy's strength left her and she gave up altogether, all well and good. But if she could not—she groaned and set herself grimly to her task.

She had covered about an eighth of the distance back when her heart leapt suddenly and she gave a sigh of relief. There were two other bobbing caps on the water coming rapidly nearer—and those two caps could belong to nobody but Mollie and Grace.

TWO OTHER BOBBING CAPS WERE COMING RAPIDLY NEARER.

That meant help—and, oh, she did need help! She was putting forth all her strength, but to her agonized fancy she was not going forward at all. Amy's almost dead weight dragging at her shoulder seemed a nightmare. Yet she dreaded beyond anything else to be relieved of the weight for that would mean—. She refused to put the awful thought into words, merely driving herself on more desperately. And all the time she was gasping out words of hope and courage to the poor girl she supported.

Amy seemed beyond words, for she made no answer, merely clutching Betty's shoulder more tightly and holding on with a grimness born of terror.

Then just as the gallant Little Captain felt her strength going and knew she could not hold out much longer, Mollie came abreast of her with Grace a few feet behind.
