I am afraid of cities. But you mustn’t leave them. If you go too far you come up against the vegetation belt. Vegetation has crawled for miles towards the cities. It is waiting. Once the city is dead, the vegetation will cover it, will climb over the stones, grip them, search them, make them burst with its long black pincers; it will blind the holes and let its green paws hang over everything. You must stay in the cities as long as they are alive, you must never penetrate alone this great mass of hair waiting at the gates; you must let it undulate and crack all by itself. In the cities, if you know how to take care of yourself, and choose the times when all the beasts are sleeping in their holes and digesting, behind the heaps of organic debris, you rarely come across anything more than minerals, the least frightening of all existants.
