When we descended to the beach and threw ourselves down under the shadow of the high white cliffs to rest, I saw there was no one about and suggested a swim. It was against old Trigger's orders, nevertheless the calm, cool water as it lazily lapped the sand proved too tempting, and very shortly we had plunged in and were enjoying ourselves. Omar left the water first, and presently I saw while he was dressing the figure of a tallish, muscular man attired in black and wearing a silk hat approaching him. As I watched, wondering what business the stranger could have with my companion, I saw that when they met Omar greeted him in native fashion by snapping fingers, as he had often done playfully to me. Whoever he might be, the stranger was unexpected, and judging from the manner in which he had been received, a welcome visitor. I was not near enough to distinguish the features of the newcomer, but remembering that I had been in the water long enough, I struck out for the shore, and presently walked up the beach towards them. Omar had dressed, and was in earnest conversation with a gigantic negro of even darker complexion than Mr. Makhana. Unconscious of my approach, for my feet fell noiselessly upon the sand, he was speaking rapidly in his own language, while the man who had approached him stood listening in meek, submissive attitude. Then, for the first time, I noticed that my friend held in his hand a grotesquely carved stick that had apparently been presented by the new-comer as his credential, together with a scrap of parchment whereon some curious signs, something like Arabic, were written. While Omar addressed him he bowed low from time to time, murmuring some strange words that I could not catch, but which were evidently intended to assure my friend that he was his humble servant. In spare moments Omar had taught me a good deal of his language. Indeed, such a ready pupil had I been that frequently when we did not desire the other fellows to understand our conversation we spoke in his tongue. But of what he was saying to this stranger, I could only understand one or two words and they conveyed to me no meaning. The negro was a veritable giant in stature, showily dressed, with one of those gaudily-coloured neckties that delight the heart of Africans, while on his fat brown hand was a large ring of very light-coloured metal that looked suspiciously like brass. His boots were new, and of enormous size, but as he stood he shifted uneasily from one foot to the other, showing that he was far from comfortable in his civilized habiliments. Without approaching closer I picked up my things and dressed rapidly, then walked forward to join my companion. "Scars!" he cried, as soon as I stood before him. "I had quite forgotten you. This is my mother's confidential adviser, Kouaga."
