“Why, Morny,” cried Rodd, catching his companion sharply by the arm, “where are the niggers?”

“Where are the niggers?” said the young Frenchman, staring.

“Yes; they have always been ready waiting till we finished our meals. They were there last night.”

“Yes,” said Morny; “they were there last night.”

“Then where are they this morning?”

Morny looked across the river and back at his companion, while the doctor, who had been conversing with the men, came hurriedly up and joined them.

“What are you two talking about?” he said.

“About those two blacks, uncle,” said Rodd, whose voice sounded rather husky.

“What about them, sir?”

“They have always been hanging about, uncle, till we had done our meals, and then waited for what was left.”
