A shriek--and the girl again disappeared. Ed went down after her, and while Cora kept in motion to sustain herself, Ed came up with the girl again in his arms. "Take hold!" he gasped to Cora. "She is hurt and cannot swim." Cora, with one well trained arm, conquered the waves, while with the other she helped support the form of the almost fainting girl, as Ed, swimming in the same way, and almost carrying the girl with his free arm, made for the shore. Forgetting everything but the danger to her friends, Bess, too, ran into the waves to meet the swimmers. "Go back!" shouted Ed. "If you lose your footing we can't help you." Scarcely had he uttered the words than Bess stumbled and fell, head foremost, into the roller that was rushing up on the shore! Fortunately the incoming water brought Bess in--fairly tumbling her out on the sand. The same power assisted Ed and Cora to land with the strange young girl. Meanwhile Jack and Walter had made their way to the bungalow, assisting the crippled woman. "Oh!" shrieked Bess, scrambling to her feet. "Oh, I--am smothered!" "So are we!" Cora managed to say. "Come, Bess. Help us revive the young lady." "Oh I--am--all--right now----" murmured the girl. "Only let me--get to mother!" A sorry looking sight indeed were the motor girls--all four of them, for the strange girl should be classed with Bess, Belle and Cora, as she, too, owned a car and drove it. True she did allow it to get beyond control, and, by a sudden wrong turn of the wheel, sent it in the ocean. Still she was a motor girl for all her inexperience. "Where are you hurt?" asked Ed, as they all stood for a moment on the beach. The strange girl was working her shoulder with evident painful effort. "I must have injured my neck or shoulder blade when I dove under the machine," she replied. "Something--is very stiff." "Let us get up to the bungalow," suggested Cora, for the strange girl seemed like one dazed. "Your mother is there, and I hope by this time she has revived." Even in their discomfiture our friends could not help noticing what a pretty and pleasant mannered girl the stranger was. Every little nicety of good breeding was perfectly evident in her gentle gratitude to her rescuers, and in her earnest solicitation for her mother. Ed led the way to the camp, while the girls followed. Belle met them at the door. "How is she?" asked Cora, knowing how anxious was the girl about her invalid mother. "She is quite revived," replied Belle, "but she wants her daughter. I am so glad you have come," hurried on Belle, without waiting for any formality. "She seems greatly worried about--Beatrice." "Oh, let me see her," exclaimed the girl. "Dear, little, darling mamma," and before the others could show the way Beatrice (for such was her name) had the crippled form clasped lovingly in her arms.
