On they come--line upon line of dark savages--advancing mostly in silence, though now and then the hum of a marching song, as some fresh group arrives at the place, rises upon the stillness in clear cadence. None are armed, unless a stick apiece and a small shield can be defined as weapons; and there is a curiously subdued note pervading the assembly--an elated look on some of those dark faces, a thoughtful one on others--but one of expectancy upon all. Each party as it arrives squats upon the ground awaiting the next. And still the tread of advancing feet, the hum of approaching voices, and presently the open space is filled with dark humanity to the number of several hundreds. During the period of waiting, chiefs, leaving their own following, greet each other, and draw apart for converse among themselves. Suddenly, and with startling nearness, there echoes forth from a crag overhead a loud resonant bark. It is answered by another and another. A volley of deep-voiced ejaculation, first startled--for their feelings are wrought up--then mirthful, arises from scores of throats. A troop of baboons has discovered this human concourse, and, secure in a lofty vantage ground, is vocally resenting its presence. But such levity is promptly checked by a sense of the serious nature of the gathering. It is clear that all are assembled who mean to come. And now the gloom lightens with amazing rapidity, as the broad disc of a full moon sails majestically forth above the jumble of serrated crags; and to it turns that sea of wild dark faces stamped with an unwonted expectation and awe, for as yet the bulk of those present have but a dim idea of the end and object of this mysterious convention. In the lamplike glow of this new light faces are clearly discernible, and amid the group of chiefs are those of Madula, and Zazwe, and Sikombo, and Umlugula, and several others holding foremost rank among their tribesmen. On this occasion, however, they are not foremost, for it is upon another group that the main interest and expectation centres. The members of this are decked out in the weird array of sorcerers, are hung around with entrails and claws, mysterious bunches of "charms," white cowhair and feather adornments, and the grinning skulls of wild animals. One alone is destitute of all ornamentation, but the grim hawk-like countenance, the snaky ferocity of the cruel stare, the lithe stealthiness of movement, stamps this man with an individuality all his own, and he is none other than Shiminya. These are the "Abantwana 'Mlimo," the hierarchy of the venerated Abstraction, the "Children of Umlimo." Of them there are perhaps two score. They are seated in a circle, droning a song, or rather a refrain, and, in the midst, Shiminya walks up and down discanting. The chiefs occupy a subsidiary place to-night, for the seat of the oracle is very near, and these are the mouthpieces of the oracle.
