ieked the plump young lady. "I tipped the boat
over!"

Joe said nothing, but looked over the side of the boat. He saw the body
of Mabel Mallison not far away. But it was at the lake bottom and did
not offer to rise.

"It's queer she doesn't come up," he thought.

Then he gave a second look and saw that the dress of the unfortunate one
was caught in some sharp rocks. Without hesitation he dived overboard,
straight for the bottom.

It was no easy matter to unfasten the garment, which was caught in a
crack between two heavy stones. But at the second tug it came free, and
a moment later both our hero and Mabel Mallison came to the surface.

"Oh!" cried two of the ladies in the row-boat. "Is she drowned?"

"I trust not," answered Joe. "Sit still, please, or the boat will surely
go over."

As best he could Joe hoisted Mabel into the craft and then clambered in
himself. As he did so the unfortunate girl gave a gasp and opened her
eyes.

"Oh!" she murmured.

"You are safe now, Mabel!" said one of her companions.

"And to think it was my fault!" murmured the plump young lady. "I shall

"Let us row for the hotel," said one of the young ladies. "Are you all

"Yes, ma'am, barring the wetting."

"It was brave of you to go down after Mabel."

"Indeed it was!" cried that young lady. "If it hadn't been for you I
might have been drowned." And she gave a deep shudder.

"I saw she was caught and that's why I went over after her," answered
our hero simply. "It wasn't so much to do."

All dripping as he was, Joe caught up the oars of the boat and sent the
craft in the direction of the hotel at a good speed. That she might not
take cold, a shawl was thrown over Mabel's wet shoulders.

The arrival of the party at the hotel caused a mild sensation. Mabel
hurried to her room to put on dry clothing, and Joe was directed to go
around to the kitchen. But when the proprietor of the place had heard
what Joe had done for his niece he sent the lad to a private apartment
and provided him with dry clothing belonging to another who was of our
hero's size.

"That was a fine thing to do, young man," said the hotel proprietor,
when Joe appeared, dressed in the dry garments, an
