In Provence, the olive has gone through some hard times, suffering from both man and nature: from freak frosts like the memorably brutal year of 1956, or from a long-lasting tendency among farmers to replace olive groves with more profitable vineyards. (Since 1929, the number of olive trees in Provence has declined from eight million to two million.) And then there’s general neglect. You see the victims on deserted, overgrown hillsides, their trunks strangled by ropes of wild ivy, entire trees almost hidden by brambles, apparently smothered to death. Amazingly, they survive. Cut away the ivy and the brambles, clean up the area around the base of the trunk, prune the tangle of branches, and in a year or so there will be olives. The intelligent camel, so it seems, is practically indestructible, capable of springing back to life again after going through an arboreal nightmare.
