In that vast territory Zouga had panned red native gold from the outcropping quartz reef.

it was a rich land and all of it was his, but it needed capital, huge amounts of capital, to take possession of it and to win the treasures that lay below it. Half his adult life had been spent in struggle to raise that capital, a fruitless struggle, for he had not yet found a single man of substance to share his vision and his dream with him.

Finally, he had in desperation appealed to the British public. He had journeyed to London once more to promote the formation of the "Central African Lands and Mining Co." to exploit his concession.

He had designed and had printed a handsome brochure, extolling the riches of the land he had named Zambezia.

He had illustrated the pages with his own drawings of fine forests and grassy plains abounding with elephant and other game. He had included a facsimile of the original concession, with the great elephant seal of Mzilikazi, King of the Matabele, at its foot. And he had distributed the brochure throughout the British Isles.

He had travelled from Edinburgh to Bristol lecturing and holding public meetings, and he had backed up this campaign with full-page advertisements in The Times and other reputable newspapers.

However, the same newspapers that had accepted his advertising fees had ridiculed his claims, while the attention of the investing public was seduced by the flotations of the South American railway companies which unhappily coincided with Zouga's promotion. He had been left with the bill for printing and distribution of the brochure, the fees for advertising and for the lawyers and the expenses of his own travelling, and when he had paid them and his passage back to Africa there remained only a few hundred sovereigns from what had once been considerable wealth.

The wealth was gone, but the responsibilities remained. Zouga looked back from the head of the span of dappled black oxen.

Aletta sat on the wagon box. Her hair was still pale gold and silky in the sunlight, but her eyes were grave and the line of her lips no longer sweet and soft, as though she had set herself against the hardships that she knew lay ahead.

Looking at her now it seemed impossible that she had once been a pretty carefree butterfly of a girl, the pampered darling of a rich father, with no thought in her head beyond London fashion newly arrived on the mailship and the preparations for the next ball in the glittering social whirl of Cape society.

She had been attracted by the romance surrounding young Major Zouga Ballantyne. He was the traveller and adventurer in far places of the African continent. There was the legend of the great elephant hunter that surrounded him, the glamour of the book that he had recently published in London. All Cape Town society was agog with this young man and envied her his suit.

That had been many years ago, an the egend ad tarnished.

Aletta's delicate breeding had not been equal to the rigours of the savage interior beyond the gentle and temperate airs of the Cape littoral, and the rough country and rougher peoples had appalled her. She had succumbed swiftly to the fevers and pestilences which had weakened her so that she suffered repeated miscarriages.

All her married life she seemed to be in child-bed, or lost in the mists of malarial fever, or waiting interminably for the golden-bearded, godlike figure whom she worshipped to return from across an ocean or from the hot and unhealthy hinterland to which she could no longer follow him.

On this journey to the diamond fields, Zouga had taken it for granted that she would once again remain at her father's home at the Cape, to guard her failing health and to care for their two boys, fruit of the only pregnancies which she had succeeded in bringing to full term.

However, she had suddenly shown an uncharacteristic determination, and none of his arguments to make her remain behind had prevailed. Perhaps she had some premonition of what was to follow, "I have been alone too long," she answered him, softly but stubbornly.

Ralph, the eldest boy, was old enough by then to ride ahead of the wagon with his father and take his shot at the springbuck herds which drifted like thin pale brown smoke across the scrubby plains of the wide Karroo.

Already he sat his rugged little Basuto pony with the panache of a hussar and he shot like a man.

Jordan, the younger boy, would sometimes take his turn at leading the fore oxen of the span, or wander away from the wagons to chase a butterfly or pick a wild flower; but mostly he was content to sit beside his mother on the wagon box while she read aloud from a small leather-bound book of romantic poetry, his green eyes sparkling with the thrilling sound of the words that he was still too young properly to understand and the brilliant Karroo sunlight turning his golden curls into an angel's halo.

It was six hundred miles from Good Hope to the fields, a journey that took the family eight weeks. They camped each night on the open veld and the night sky was clear and cold and brilliant with white stars that shone like the diamonds that they were certain awaited them at the end of the journey.

Sitting beside the watch-fire with his two sons flanking him, Zouga would talk in that magnetic compelling tone that had the two small boys rigid with attention.

He spun descriptions of great elephant hunts and ancient ruined cities, of graven idols and red native gold in the land to the north, the land to which he would one day take them.

Listening quietly from across the fire, wrapped in a shawl against the night chill, Aletta would find herself enchanted with the romantic dream, as she had been as a girl, and she wondered again at herself and the strange attraction of this intense golden-bearded man who was her husband of so many years and still so often seemed a stranger to her.

She listened as he told the boys how he would fill their caps with diamonds, fat glistening diamonds, and then at last they would set out on the final journey northwards.

She found herself believing it all again, though she had long ago experienced the first disillusion. He was so persuasive, so vital and strong and convincing, that the failures and the frustrations seemed of no account, only a temporary check on the destiny he had set for all Of them.

The days rolled by at the leisurely pace of the wagon wheels and became weeks, weeks in which they travelled across a great sun-washed plain that was furrowed by steep dry watercourses and studded with the dense dark-green camel-thorn trees in whose branches hung the enormous communal nests of thousands of dry-land weaver birds, each nest the size of a haystack, growing until it snapped off the sturdy branch that supported it.

The monotonous line of the horizon was relieved by the occasional low hillock, the kopje of the African continent, and the track led them directly towards one of these.

Colesberg kopje. It was only weeks after they had arrived at it that Zouga heard the story of how the diamond hillock had been discovered.

A few miles north of Colesberg kopje the plain was broken by the bed of a wide shallow river, along whose banks the trees were taller and greener. The trek Boers had called it the Vaal river, which in the African Dutch taal means "the grey river", the colour of its sluggish waters. From its bed and from the alluvial gravels of the flood plains along its course, a small colony of diamond diggers had for years been gleaning the odd sparkling stone.

It was dreary, back-breaking work and after the first rush of hopeful diggers only the hardiest had remained.

These doughty souls had known for years that it was possible to pick up an occasional small diamond of inferior quality on the dry ground thirty miles south of the river, in fact the surly old Boer named De Beer who owned the ground in that area was selling licences to diamond claims on his property, although he favoured diggers of his own people and was notoriously prejudiced against granting "briefies" to Englishmen.
