The two storms were rapidly rushing together. Between them was a gulf of blue sky, and from time to time flashes of blinding light passed across this gulf, leaping from cloud to cloud. I remember that they reminded me of the story of the heathen god Jove and his thunderbolts.
The storm that was shaped like a giant and ringed with the glory of the sinking sun made an excellent Jove, and I am sure that the bolts which leapt from it could not have been surpassed even in mythological times. Oddly enough, as yet the flashes were not followed by thunder.
A deadly stillness lay upon the place, the cattle stood silently on the hillside, even the natives were awed to silence. Dark shadows crept along the bosom of the hills, the river to the right and left was hidden in wreaths of cloud, but before us and beyond the combatants it shone like a line of silver beneath the narrowing space of open sky. Now the western tempest was scrawled all over with lines of intolerable light, while the inky head of the cloud-giant to the east was continually suffused with a white and deadly glow that came and went in pulses, as though a blood of flame was being pumped into it from the heart of the storm.
The silence deepened and deepened, the shadows grew blacker and blacker, then suddenly all nature began to moan beneath the breath of an icy wind. On sped the wind; the smooth surface of the river was ruffled by it into little waves, the tall grass bowed low before it, and in its wake came the hissing sound of furious rain.
Ah! the storms had met. From each there burst an awful blaze of dazzling flame, and now the hill on which we sat rocked at the noise of the following thunder. The light went out of the sky, darkness fell suddenly on the land, but not for long. Presently the whole landscape grew vivid in the flashes, it appeared and disappeared, now everything was visible for miles, now even the men at my side vanished in the blackness. The thunder rolled and cracked and pealed like the trump of doom, whirlwinds tore round, lifting dust and even stones high into the air, and in a low, continuous undertone rose the hiss of the rushing rain.
I put my hand before my eyes to shield them from the terrible glare, and looked beneath it towards the lists of iron-stone. As flash followed flash, from time to time I caught sight of the two wizards.
They were slowly advancing towards one another, each pointing at his foe with the assegai in his hand. I could see their every movement, and it seemed to me that the chain lightning was striking the iron-stone all round them.
Suddenly the thunder and lightning ceased for a minute, everything grew black, and, except for the rain, silent.
"It is over one way or the other, chief," I called out into the darkness.
"Wait, white man, wait!" answered the chief, in a voice thick with anxiety and fear.
Hardly were the words out of his mouth when the heavens were lit up again till they literally seemed to flame. There were the men, not ten paces apart. A great flash fell between them, I saw them stagger beneath the shock. Indaba-zimbi recovered himself first--at any rate when the next flash came he was standing bolt upright, pointing with his assegai towards his enemy. The chief's son was still on his legs, but he was staggering like a drunken man, and the assegai had fallen from his hand.
