But deep as the water was, Ruth had no fear for herself. She loved to swim and the instructor at Briarwood had praised her skill. The only anxiety she had as she sank beneath the surface was for Mary Cox, who had already gone down twice.
She had leaped into the lake near where The Fox had disappeared. Once beneath the surface, Ruth opened her eyes and saw the shadow of somebody in the water ahead. Three strokes brought her within reach of it. She seized Mary Cox by the hair, and although her school fellow was still sinking, Ruth, with sturdy strokes, drew her up to the surface.
What a blessing it was to obtain a draught of pure air! But The Fox was unconscious, and Ruth had to bear her weight up, while treading water, until she could dash the drops from her eyes. There was the lifebuoy not ten yards away. She struck out for it with one hand, while towing Mary with the other. Long before the steamer had been stopped and a boat lowered and manned, Ruth and her burden reached the great ring, and the girls were comparatively safe.
Tom Cameron came in the boat, having forced himself in with the crew, and it was he who hauled Mary Cox over the gunwale, and then aided Ruth into the boat.
"That's the second time you've saved that girl from drowning, Ruth," he gasped. "The first time was last Fall when you and I hauled her out of the hole in the ice on Triton Lake. And now she would have gone down and stayed down if you hadn't dived for her. Now! don't you ever do it again!" concluded the excited lad.
Had Ruth not been so breathless she must have laughed at him; but there really was a serious side to the adventure. Mary Cox did not recover her senses until after they were aboard the steamer. Ruth was taken in hand by a stewardess, undressed and put between blankets, and her clothing dried and made presentable before the steamer docked at the head of the lake.
As Tom Cameron had said, Mary Cox had fallen through the ice early in the previous Winter, and Ruth had aided in rescuing her; The Fox had never even thanked the girl from the Red Mill for such aid. And now Ruth shrank from meeting her and being thanked on this occasion. Ruth had to admit to herself that she looked forward with less pleasure to the visit to the seashore with Heavy because Mary Cox was to be of the party. She could not like The Fox, and she really had ample reason.
