"I don't know," Eustace answered—"a black-fellow of some sort. I wonder if I—I killed him."

There had fallen a sudden silence outside; the awful howling had ceased.

Eustace sat down on the edge of his mother's bed feeling sick and shivery. To have killed a man—a white fellow, black-fellow, any sort of fellow; it was horrible!

The most extraordinary sounds arose from the veranda. Had Robertson gone mad, or what could be the matter with him?

"Ho-ho-ho! ha-ha-ha! ho-ho-ho-ho!" he roared.

Every one stood as if paralyzed. There was something terribly uncanny about the laughter. It seemed so ill-timed, so jarring and unkind.

Robertson appeared at the broken window.

"Upon my word, Eustace," exclaimed the Scotsman, "it's the best joke ever I heard or saw. Come and look at your black-fellow and be proud of yourself."

"I can't!" said Eustace, his knees knocking together as he attempted to stand, and he fell back on the bed.

"Oh, what is it, Mr. Robertson?" asked Mrs. Orban.
