The sag of the rope in the water began to trouble Tom Jonah, strong as he was. Quickly the girl drew off her shoes and stockings and waded in to meet the laboring dog.

“Come on, sir! now we’ll get them!” she urged, laying hold of the line.

The dog scrambled ashore, barking loudly. The line was taut and the boat had swung around, tugging on the other end like a thing of life.

“Now we have them!” cried the girl.

She pulled hard on the rope. Tom Jonah, seeing what she was doing, caught the rope in his strong jaws, and set back to pull, too. Tess and Dot screamed with delight.

As the big girl slowly drew in the rope the dog backed up the beach, and so the cedar boat, with its two remaining passengers, came to land.

“Oh, dear me! Oh, dear me!” gasped Dot, standing in the bow of the boat. “I’m so glad to get ashore. And so’s my Alice-doll,” she added, seriously.

Tess helped her sister to jump down upon the sand and then followed, herself. Tom Jonah dropped the rope and bounded about them, barking his satisfaction. But the strange girl was looking up and down the river, and over at the opposite shore, with a mind plainly disturbed.

“Come on, now!” she said, sharply. “Unfasten the rope from that dog’s collar. We’ll keep that. It may come in handy.”

“Don’t you want it to pull the boat up on the beach?” asked Tess, as she obeyed the command.
