“So father started in the Bright Eyes. He did not shoot right up the middle of the lake, as he would have done had the day been fair. The lake is twenty miles broad, you know, in the middle. So he kept near our side–the south side it is–and did not lose sight of the shore at first.
“But at Gannet Island he knew he had better run outside. You see, the strait between the island and the shore is narrow and, when the wind is high, it sometimes is dangerous in there. Why, ten years ago, one of the little excursion steamers that used to ply the lake then, got caught in that strait and was wrecked!
“So father had to go outside of Gannet Island. The fog shut down as thick as a blanket before he more than sighted the end of the island. He kept on, remembering what Dr. Shelton had said, and that is where he made a mistake,” said Polly, shaking her head. “He ought to have turned right around and come back to our landing.”
“Oh, dear me! what happened to him?” cried Wyn, eagerly.
“The fog came down, thicker and thicker,” proceeded the boatman’s daughter. “And the wind rode down upon father, too. Wind and fog together are not usual; but when the two combine it is much worse than either alone. You see, the thick mist swirling into father’s eyes, driven head-on by the wind, blinded him. He steered a shade too near the shore.
“Suddenly the Bright Eyes struck. A motor boat, going head-on upon a snag, can be easily wrecked. The boat struck and stuck, and father leaped up to shut off the engine.
“As he did so, something swished through the blinding fog and struck him, carrying him backward over the stern of the boat. Perhaps it was the loss of his weight that allowed the Bright Eyes to scrape over the snag. At least, she did so as father plunged into the lake, and as he sank he knew that the boat, with her engine at half speed, was tearing away across the lake.
“It was the drooping limb of a tree that had torn father from the stern of the motor boat,” continued Polly Jarley. “It may have been a big root of the same tree, under water, that had proved the finish of the boat. For nobody ever saw the Bright Eyes again. She just ran off at a tangent, into the middle of the lake, somewhere, we suppose, and filled and sank.”
“Oh, dear me! And your father?” asked Wyn, anxiously.
“He got ashore on the island. Then he signalled to me, and I went off during a lull in the storm, and got him. He went to bed, and it was three months before he was up and around again.
