"I am sure," she said, "that a few hours' rest in camp will set me on my feet. All I need is rest. I didn't sleep very soundly last night."

I felt myself growing red, and I looked away from them both.

"Oh," said Kemper, in apparent surprise, "I thought you had slept soundly all night long."

"Nobody," said I, "could have slept very pleasantly during that musical performance of yours."

"Were you singing?" she asked innocently of Kemper.

"He was singing when he wasn't firing off his pistol," I remarked. "No wonder you couldn't sleep with any satisfaction to yourself."

"Confound it!" I exclaimed. "I'm going to stop that right now."

Kemper rose and followed me as I started for the woods; but as we passed the beached boats Grue appeared from among the trees.
