In a second he will gain it. They cannot fire, every nerve is strained to overtake him, to head him off. He sees their foremost line. Now it is in front of him. No, not quite! His revolver is out, and the heavy bullet crashes almost point blank through the foremost. Another springs up in front of him, a gigantic warrior, his broad spear upraised. Before it can descend the fugitive is upon him, and the momentum is too great. Grappled together they topple over the edge, and go crashing down, the white man and the savage, into unknown depths. The bushes close over their heads and they are in almost total darkness. There is a mighty splash of water and both are engulfed--yet, still grappled, they rise to the surface again, and the blue glare of the lightning, darting down, reveals the slanting earth walls of the chasm, reveals to each the face of the other as they rise above the turgid water, gasping and sputtering. The savage has lost his assegai in the fall, and the white man is groping hungrily, eagerly, for his sheath knife. "Ah, ah! Ziboza! Did I not tell thee thou wert dead?" "Not yet, dog Makiwa!" growls the other, in the ferocity of desperation striving to bury his great teeth in his adversary's face. But Blachland is in condition as hard as steel, and far more at home in the water than the Matabele chief, so while gripping the latter by the wrists, he ducks his head beneath the surface, endeavouring to drown him if possible. He dare not let go his hold lest he should be the one grasped, and those above dare not fire down for fear of shooting their chief--even if they could see the contending parties--which they cannot. But the awful reverberations of the thunder-peal boom and shiver within that pit as of hell, and the lightnings gleam upon the brown turgid surface, and the straining faces of the combatants are even as those of striving fiends. They touch ground now, then lose it again, for the bottom is but a foothold of slippery mud. Nearer, nearer to the main stream their struggles have carried them, until the sombre roar of the flood sounds deafening in their ears, and still the awful strife goes on. "Ah--ah, Ziboza. I told thee thou shouldst meet death this day. _Ha! Nantzia_! [that is it] _Ha_!" And with each throaty, bloodthirsty gasp he plunges the knife, which he has at last managed to free, into the body of the nearly exhausted chief, drawing it down finally in a terrible ripping stroke. A single gasping groan, and Ziboza sinks, as his adversary throws him from him. And then the said adversary knows no more. The swirl of the flood sweeping into the chasm, seems to rope him out, and the body of Hilary Blachland, together with that of his savage antagonist, is borne down within the raging rush of waters, rolling over and over on its way to the Zambesi and the sea.
