"Lieutenant Ali," he said, "get out my log and put it in old Sanders' cabin, make me a cup of tea and keep her jolly old head east, east by north."

"Ay, ay, sir," said Ali in excellent English.

The "log" which Bones kept was one of the secret documents which never come under the eye of the superior authorities. There were such entries as—

"Wind N.N.W. Sea calm. Hostile craft sighted on port bow, at 10.31 a.m. General Quarters sounded 10.32. Interrogated Captain of the hostile craft and warned him not to fish in fair-way. Sighted Cape M'Gooboori 12.17, stopped for lunch and wood."

What though Cape M'Gooboori was the village of that name and the "calm sea" was no more than the placid bosom of the Great River? What though Bones's "hostile craft" was a dilapidated canoe, manned by one aged and bewildered man of the Isisi engaged in spearing fish? Bones saw all things through the rosy spectacles of adventurous youth denied its proper share of experience.

At sunset the Zaire came gingerly through the shoals that run out from the Isongo beach, and Bones went ashore to conduct his investigations. It chanced that the evening had been chosen by M'lama, the witch, for certain wonderful manifestations, and the village was almost deserted.

In a wood and in a place of green trees M'lama sat tossing her sheep shanks, and a dense throng of solemn men and women squatted or sat or tiptoed about her—leaving her a respectable space for her operations. A bright fire crackled and glowed at her side, and into this, from time to time, she thrust little sticks of plaited straw and drew them forth blazing and spluttering until with a quick breath she extinguished the flame and examined the grey ash.

"Listen, all people," she said, "and be silent, lest my great ju-ju strike you dead. What man gave me this?"

"It was I, M'lama," said an eager woman, her face wrinkled with apprehension as she held up her brown palm.

The witch peered forward at the speaker.
