For instance. It is the custom in Africa to bum fireguards for dwelling-houses and outhouses against the veld fires which rage across country all through the dry season. My father was burning a fireguard for the cow shed. It was a windless day. The grass was short. The fire would burn slowly. Yet it was in the nature of things that any small animal, grounded bird, insect or reptile in the two-hundred-yard-wide, mile-long stretch of fire would perish, not, presumably, without pain. My father stood, sombrely contemplating the creeping line of small flames. The boss-boy stood beside him. Suddenly there fled out from the smoke-filled grass at their feet, a large fieldmouse. The boss-boy brought down a heavy stick across the mouse’s back. It was dying. The boss-boy picked up the mouse by the tail, and swinging the still-twitching creature, continued to stand beside my father, who brought down his hand in a very hard slap against the boss-boy’s face. So unprepared was he for this, that he fell down. He got up, palm to his cheek, looking at my father for an explanation. My father was rigid with incommunicable anger. ‘Kill it at once,’ he said, pointing to the mouse, now dead. The boss-boy flung the mouse into a nest of flames, and stalked off, with dignity.

‘If there is one thing I can’t stand it’s cruelty of any kind,’ my father said afterwards, in explanation of the incident.

Which is comparatively uncomplicated, not to say banal. More obliquely rewarding in its implications was the affair with the Dutchman. My father was short of money, and had undertaken to do, in his spare time, the accounting for the small goldmine two miles away. He went over three times a week for this purpose. One day, several hundred pounds were missing. It was clear that Van Reenan, who managed the mine for a big company, had stolen it, and in such a way that it looked as if my father had, My father was whitely silent and suffering for some days.
