In the big house at Dorking where he had spent his childhood, the ten-acre estate, where his father had lorded (himself a one-time Commissioner), he had watered the seed of desire which heredity had irradicably sown in his bosom; a desire not to be shaped by words, or confirmed in phrase, but best described as the discovery-lust, which send men into dark, unknown places of the world to joyously sacrifice life and health that their names might be associated with some scrap of sure fact for the better guidance of unborn generations.

Bones was a dreamer of dreams.

On the bridge of the Zaire he was a Nelson taking the Victory into action, a Stanley, a Columbus, a Sir Garnet Wolseley forcing the passages of the Nile.

Small wonder that he turned from time to time to the steersman with a sharp "Put her to starboard," or "Port your helm a little."

Less wonder that the wholly uncomprehending steersman went on with his work as though Bones had no separate or tangible existence.

On the fourth evening after leaving headquarters, Bones summoned to his cabin Mahomet Ali, the sergeant in charge of his soldiers.

"O, Mahomet," said he, "tell me of this N'bosini of which men speak, and in which all native people believe, for my lord M'ilitani has said that there is no such place and that it is the dream of mad people."

"Master, that I also believe," said Mahomet Ali; "these people of the river are barbarians, having no God and being foredoomed for all time to hell, and it is my belief that his idea of N'bosini is no more than the Paradise of the faithful, of which the barbarians have heard and converted in their wild way."

"Tell me, who talks of N'bosini," said Bones, crossing his legs and leaning back in his chair, his hands behind his head; "for, remember that I am a stranger amongst you, Mahomet Ali, coming from a far land and having seen such marvels as——"

He paused, seeking the Arabic for "gramaphone" and "motor-'bus," then he went on wisely: "Such marvels as you cannot imagine."
