Indaba-zimbi, beckoning away vigorously. "Look now at my cloud-child."

I looked; the eastern storm was spreading itself from earth to sky, and in shape resembled an enormous man. There was its head, its shoulders, and its legs; yes, it was like a huge giant travelling across the heavens. The light of the setting sun escaping from beneath the lower edge of the western storm shot across the intervening space in a sheet of splendour, and, lighting upon the advancing figure of cloud, wrapped its middle in hues of glory too wonderful to be described; but beneath and above this glowing belt his feet and head were black as jet. Presently, as I watched, an awful flash of light shot from the head of the cloud, circled it about as though with a crown of living fire, and vanished.

"Aha," chuckled old Indaba-zimbi, "my little boy is putting on his man's ring," and he tapped the gum ring on his own head, which natives assume when they reach a certain age and dignity. "Now, white man, unless you are a bigger wizard than either of us you had better clear off, for the fire-fight is about to begin."

I thought this sound advice.

"Good luck go with you, my black uncle," I said. "I hope you don't feel the iniquities of a mis-spent life weighing on you at the last."

"You look after yourself, and think of your own sins, young man," he answered, with a grim smile, and taking a pinch of snuff, while at that very moment a flash of lightning, I don't know from which storm, struck the ground within thirty paces of me. That was enough for me, I took to my heels, and as I went I heard old Indaba-zimbi's dry chuckle of amusement.

I climbed the hill till I came to where the chief was sitting with his indunas, or headmen, and sat down near to him. I looked at the man's face and saw that he was intensely anxious for his son's safety, and by no means confident of the young man's powers to resist the magic of Indaba-zimbi. He was talking in a low voice to the induna next to him. I affected to take no notice and to be concentrating my attention on the novel scene before me; but in those days I had very quick ears, and caught the drift of the conversation.

"Hearken!" the chief was saying, "if the magic of Indaba-zimbi prevails against my son I will endure him no more. Of this I am sure, that when he has slain my son he will slay me, me also, and make himself chief in my place. I fear Indaba-zimbi. Ou!"

"Black One," answered the induna, "wizards die as dogs die, and, once dead, dogs bark no more."

"And once dead," said the chiefs, "wizards work no more spells," and he bent and whispered in the induna's ear, looking at the assegai in his hand as he whispered.

"Good, my father, good!" said the induna, presently. "It shall be done to-night, if the lightning does not do it first."

"A bad look-out for old Indaba-zimbi," I said to myself. "They mean to kill him." Then I thought no more of the matter for a while, the scene before me was too tremendous.

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.

Darkness! then again a flash, more fearful, if possible, than any that had gone before. To me it seemed to come from the east, right over the head of Indaba-zimbi. At that instant I saw the chief's son wrapped, as it were, in the heart of it. Then the thunder pealed, the rain burst over us like a torrent, and I saw no more.

The worst of the storm was done, but for a while the darkness was so dense that we could not move, nor, indeed, was I inclined to leave the safety of the hillside where the lightning was never known to strike, and venture down to the iron-stone. Occasionally there still came flashes, but, search as we would, we could see no trace of either of the wizards. For my part, I believed that they were both dead. Now the clouds slowly rolled away down the course of the river, and with them went the rain; and now the stars shone in their wake.

"Let us go and see," said the old chief, rising and shaking the water from his hair. "The fire-fight is ended, let us go and see who has conquered."

I rose and followed him, dripping as though I had swum a hundred yards with my clothes on, and after me came all the people of the kraal.

We reached the spot; even in that light I could see where the iron-stone had been split and fused by the thunderbolts. While I was staring about me, I suddenly heard the chief, who was on my right, give a low moan, and saw the people cluster round him. I went up and looked. There, on the ground, lay the body of his son. It was a dreadful sight. The hair was burnt off his head, the copper rings upon his arms were fused, the assegai handle which lay near was literally shivered into threads, and, when I took hold of his arm, it seemed to me that
