In Rex Kingdon's mind a thought took form: "An enemy hath done this!"

CHAPTER XXV.

THE EIGHT-OARED SHELL.

The sun broke gloriously through the clouds, and it became a lovely morning. The Walcott Hall boys began finally to feel more cheerful. They spread out their belongings to dry in the sun, and Peewee actually took spade and pick and went to work on the shallow trench and drains that should surround every tent, no matter how good the natural drainage is.

While he was sweating and grunting over his work, he looked off on the water, and promptly called:

"See the ca-noe! Do you see the ca-noe? What is the ca-noe doing?"

"That Indian and Kirby are just getting back from Blackport," said Phillips, after glancing in the same direction.

"They must have started mighty early," Midkiff said. "They've had to beat up the sound against a stiff breeze."

Kingdon said nothing, but he watched the two in the canoe make a landing. The light craft was heavily laden. He was quite sure it had made no quick passage from Blackport Channel; and at sunrise the weather had not cleared.

With an idea in his head that he did not mention to the others, Kingdon wandered away by himself for a tramp along shore, strolling westerly. His chums had expressed their wonderment regarding the rolling of the bowlder, all through breakfast and afterward; but they suspected nothing. They were quite satisfied that it had been set in motion by the heavy rain.
