Suddenly, little Phil, who had been lying at ease, with his head against the thwarts, arose on his elbow and cried out:

"Wha'dat?"

"What is what, Phil?" asked Oriana. "Why, Phil, you have been dreaming," she added, observing the lad's confusion at having spoken so vehemently.

"Miss Orany, dar's a boat out yonder. I heard 'em pulling, sure."

"Nonsense, Phil! you've been asleep."

"By Gol! I heard 'em, sure. What a boat doing round here dis time o' night? Dem's some niggers arter chickens, sure."

And little Phil, satisfied that he had fathomed the mystery, lay down again in a fit of silent indignation. The boat was put about, but the wind had died away, and the sail flapped idly against the mast. Harold, glad of the opportunity for a little exercise, shipped the sculls and bent to his work.

"Miss Oriana, put her head for the bank if you please. We shall have less current to pull against in-shore."

The boat glided along under the shadow of the bank, and no sound was heard but the regular thugging and splashing of the oars and the voices of insects on the shore. They approached a curve in the river where the bank was thickly wooded, and dense shrubbery projected over the stream.

"Wha' dat?" shouted Phil again, starting up in the bow and peering into the darkness. A boat shot out from the shadow of the foliage, and her course was checked directly in their path. The movement was so sudden that, before Harold could check his headway, the two boats fouled. A boathook was thrust into the thwarts; Arthur sprang to the bows to cast it off.
