We carry with us the wonders we seek without us; there is all Africa and her prodigies in us.Sir Thomas Browne: Religio Medici.We were talking about the persistence of race qualities-how you might bury a strain for generations under fresh graftings but the aboriginal sap would some day stir. The obvious instance was the Jew, and Pugh had also something to say about the surprises of a tincture of hill blood in the Behari. Peckwether, the historian, was inclined to doubt. The old stock, he held, could disappear absolutely as if by a chemical change, and the end be as remote from the beginnings as-to use his phrase-a ripe Gorgonzola from a bucket of new milk."I don't believe you're ever quite safe," said Sandy Arbuthnot."You mean that an eminent banker may get up one morning with a strong wish to cut himself shaving in honour of Baal?""Maybe. But the tradition is more likely to be negative. There are some things that for no particular reason he won't like, some things that specially frighten him. Take my own case. I haven't a scrap of real superstition in me, but I hate crossing a river at night. I fancy a lot of my blackguard ancestors got scuppered at moonlight fords. I believe we're all stuffed full of atavistic fears, and you can't tell how or when a man will crack till you know his breeding.""I think that's about the truth of it," said Hannay, and after the discussion had rambled on for a while he told us this tale.Just after the Boer War (he said) I was on a prospecting job in the north-eastern Transvaal. I was a mining engineer, with copper as my speciality, and I had always a notion that copper might be found in big quantities in the Zoutpansberg foothills. There was of course Messina at the west end, but my thoughts turned rather to the north-east corner, where the berg breaks down to the crook of the Limpopo. I was a young man then, fresh from two years' campaigning with the Imperial Light Horse, and I was thirsty for better jobs than trying to drive elusive burghers up against barbed wire and blockhouses. When I started out with my mules from Pietersburg on the dusty road to the hills, I think I felt happier than ever before in my life.I had only one white companion, a boy of twenty-two called Andrew Du Preez. Andrew, not Andries, for he was named after the Reverend Andrew Murray, who had been a great Pope among the devout Afrikanders. He came of a rich Free State farming family, but his particular branch had been settled for two generations in the Wakkerstroom region along the upper Pongola. The father was a splendid old fellow with a head like Moses, and he and all the uncles had been on commando, and most of them had had a spell in Bermuda or Ceylon. The boy was a bit of a freak in that stock. He had been precociously intelligent, and had gone to a good school in the Cape and afterwards to a technical college in Johannesburg. He was as modern a product as the others were survivals, with none of the family religion or family politics, very keen on science, determined to push his way on the Rand-which was the Mecca of all enterprising Afrikanders-and not very sorry that the War should have found him in a place from which it was manifestly impossible to join the family banner. In October '99 he was on his first job in a new mining area in Rhodesia, and as he hadn't much health he was wise enough to stick there till peace came.
