“Hold her—while I try—for Miss Higley!” cried Dorothy, as Tavia, supporting her burden on one arm and grasped the cross bar of the chute with her other and yelled for help.

Dorothy was now under water, groping for the other lost one. But she had to come up for air without bringing Miss Higley.

Down she went again, taking a long breath and determining to remain under until she could get a grip on the clothing of the teacher. Now the others were close at hand to assist Tavia in caring for Edna. Down and down Dorothy went, the water gurgling in her ears—down and down into the depths.

It seemed as if she could not stand the strain and pressure. A trail of bubbles and a swirl of the surface of the lake marked where she had disappeared.

Rose-Mary and Dick were the first to reach Tavia, and they at once took charge of the unconscious one, floating her to shore between them. Then others came up to the chute, white, frightened and trembling at the news Tavia gasped out to them. So alarmed were they that none of them dared venture to help Dorothy down there in the blackness and silence, at her grewsome task.

Tavia, as soon as she had recovered her breath, had started off to assist Dick and Rose-Mary in bringing Edna to shore, as the task was no light one for the three swimmers. Then, as she got into shallow water Tavia turned, suddenly remembering something, and shouted to the girls about the chute:

“Go for Dorothy! She is under there, looking for Miss Higley!”

But, as one or two of the braver girls, feeling the need of action, prepared to dive, they saw the pale face of Dorothy Dale come to the surface, and they saw that, in her arms, she held clasped the form of Miss Higley. But the hand that Dorothy stretched out to grasp the bottom of the chute, that she might support herself and the inert burden, just failed to catch hold of the wooden brace, and, amid a swirl of waters Dorothy went down again, out of sight, with the unconscious teacher.

CHAPTER VIII
A LIVELY AFTERNOON

There followed an eternity of suspense for those watching for the reappearance of Dorothy. The missing of the hold she expected to get on the board and the effort to keep Miss Higley up, together with the struggle she had gone through, caused the girl to lose all control of herself. She had sunk instantly without having any opportunity of using her free arm to keep herself above water.
