‘Avoid a rush-hour’ must be the slogan of large cities the world over. If it is, it’s a slogan no one takes at least notice of. Twice a day, with predictable regularity, the pot boils over. Whenever you look it’s people, people, people. The trains which leave or arrive every few minutes are packed: an endless procession of human sardine tins. The streets are so crowded, there is hardly room to move on the pavement. The queues for buses reach staggering proportions. It takes ages for a bus to get to you because the traffic on the roads has virtually come to a standstill. Even when a bus does at least arrive, it’s so full, it can’t take any more passengers. The smallest unforeseen event can bring about conditions of utter chaos. A power-cut, for instance, an exceptionally heavy snowfall or a minor derailment must always make city-dwellers realize how precarious the balance is. The extraordinary thing is not that people put up with these conditions, but that they actually choose them in preference to anything else. Large modern cities a too big to control. They impose their own living conditions on the people who inhabit them. City-dwellers are obliged by their environment to adopt a wholly unnatural way of life. They lose touch with the land and the rhythm of nature. It’s possible to live such an air conditioned existence in the large city that you are barely conscious of the seasons. A few flowers in a public park (if you have time to visit it) may remind you whether it’s spring or summer. A few leaves clinging to the pavement may remind you it is autumn. Beyond that, what is going on in nature seems totally irrelevant. Tall buildings blot out the sun, traffic fumes pollute the atmosphere. Even the distinction between day and night is lost. The flow of traffic goes on unceasingly and the noise never stops.
