The covenant - James A. Michener [296]
But in a wonderfully subtle and corrective way Nxumalo's good fortune was beginning to produce its own penalties, for an ancient black tradition had been amended to provide a clever strategy for leveling society and cutting off any upstart whose popularity and power might begin to threaten the king's. This was the smelling-out ritual; now when witch-seekers coursed through the crowd, they were identifying those subversive persons whose removal would purify the tribe.
A smelling-out was conducted on sound psychological principles: as the witch-seekers with their gall bladders, snake skeletons and wildebeest tails dashed through the assembly, the crowd uttered the low, throbbing sound of a thousand voices moaning. If the seekers approached someone who by common consent ought to be removed from society, the humming increased to an audible roar, assuring the seekers that this man's death would be popular. In this way Zulu society cleansed itself. With subtle tactic it announced a consensus that was immediately enforced, for as soon as the witch-seekers nominated a man by waving their wildebeest tails in his face, he was grabbed, bent double, and destroyed with four bamboo skewers.
Nxumalo, as he accumulated fresh proofs of the king's favor, realized that he was moving into the realm of danger when the witch-seekers could mysteriously decide that the Zulu had had just about enough of him. Rumors were already circulating: 'Nxumalo? He came from nowhere. Connived against better men to win leadership of the iziCwe. Failed in his mission to Mzilikazi. Now has more cattle than a man should dream of owning. Nxumalo, like the white stork, flies too high.' So now whenever the Zulu were summoned for the next batch of removals, he began to sweat, appreciating like an ancient philosopher the transient nature of human glory.
In spite of this encroaching danger, he was needed by the Zulu, for although Shaka's system was well-nigh perfect, it had one self-destroying weakness: if a nation is totally geared to the waging of war, it had better ensure that war keeps occurring somewhere; and if incessant warfare is the rule, then trusted leaders like Nxumalo are essential. Every improvement that Shaka made obligated him to seek opponents against whom to test it, for he dared not allow his war machine to rest. It had to be housed and fed and armed with iron-tipped assegais: whole communities did nothing but forge iron; others spent their days fabricating stinkwood shafts.
So, like the emperors of Rome dispatching their legions to the far frontiers in search of new enemies, Shaka sent his regiments to distant valleys, where tribes that had committed no offense found themselves surrounded. And because Zulu warriors needed constant practice with their stabbing assegais, they collected few prisoners, but many cattle and women. This increased the wealth of the victors but not their stability, and many men discovered that as they acquired more cattle and wives, they also acquired the enmity of their friends. Many a prospering Zulu who was nominated by the witch-seekers wondered as he died in skewered agony how it all happened. War threw men upward, but the moaning of the populace dragged them back down.
It was in 1826, when Hilary and Emma Salt wood were entering Salisbury to visit his mother, that Shaka became acutely aware that he, too, formed part of this vast, impersonal process of
