Farther down the platform I had another excellent chance. A man in the uniform of a railway inspector, with a correct peaked cap, epaulettes, and neatly pressed trousers was walking towards me. But the interesting and photogenic feature was that he carried a shoe in each hand and was in his bare feet. They were big splayed feet, as blunt and white as turnips. I waited until he passed, and then clicked. But he heard the click and turned to yell a meaningful insult. After that I took my pictures with more stealth.

Molesworth saw me idling on the platform and said, 'I think I shall board. I don't trust this train any more.'

But everyone was on the platform; indeed, all the platforms at Belgrade Station were filled with travellers, leaving with me the unforgettable image of Belgrade as a terminal where people wait for trains that will never arrive, watching locomotives endlessly shunting. I pointed this out to Molesworth.

He said, 'I think of it now as getting duffilled. I don't want to get duffilled.' He hoisted himself into Car 99 and called out, 'Don't you get duffilled!'

We had left the Italian conductor at Venice; at Belgrade our Yugoslav conductor was replaced by a Bulgarian conductor.

'American?' said the Bulgarian as he collected my passport.

I told him I was.

'Agnew,' he said; he nodded.

'You know Agnew?'

He grinned. 'He is in bad situation.'

Molesworth, all business, said, 'You're the conductor, are you?'

The Bulgarian clicked his heels and made a little bow.

'Wonderful,' said Molesworth. 'Now what I want you to do is clean out those bottles.' He motioned to the floor of his compartment, where there was an impressive heap of wine bottles.

'The empty ones?' The Bulgarian smirked.

'Quite right. Good point. Carry on,' said Moles-worth, and joined me at the window.

The Belgrade outskirts were leafy and pleasant, and as it was noon by the time we had left the station, the labourers we passed had downed their tools and were sitting cross-legged in shady spots by the railway line having lunch. The train was going so slowly, one could see the plates of sodden cabbage and could count the black olives in the chipped bowls. These groups of eaters passed loaves of bread the size of footballs, reducing them by hunks and scrubbing their plates with the pieces.

Much later on my trip, in the bar of a Russian ship in the Sea of Japan, on my way from the Japanese railway bazaar to the Soviet one beginning in Nakhodka, I met a jolly Yugoslav named Nikola who told me, 'In Yugoslavia we have three things – freedom, women, and drinking.'

'But not all three at the same time, surely?' I said, hoping he wouldn't take offence. I was seasick at the time, and I had forgotten Yugoslavia, the long September afternoon I had spent on the train from Belgrade to Dimitrovgrad, sitting in my corner seat with a full bottle of wine and my pipe drawing nicely.

There were women, but they were old, shawled against the sun and yoked to green watering cans in trampled cornfields. The landscape was low and uneven, barely supporting in its dust a few farm animals, maybe five motionless cows, and a herdsman leaning on a stick watching them starve in the same way the scarecrows -two plastic bags on a bony cross-piece – watched the devastated fields of cabbages and peppers. And beyond the rows of blue cabbage, a pink pig butted the splintery fence of his small pen and a cow lay under a goal of saplings in an unused football field. Red peppers, as crimson and pointed as clusters of poinsettias, dried in the sun outside farm cottages in districts where farming consisted of men stumbling after oxen dragging wooden ploughs and harrows, or occasionally wobbling on bicycles loaded with hay bales. Herdsmen were not simply herdsmen; they were sentries, guarding little flocks from marauders; four cows watched by a woman, three grey pigs driven by a man with a truncheon, scrawny chickens watched by scrawny children. Freedom, women, and drinking was Nikola's definition; and there was a woman in a field pausing to tip a water bottle to her mouth; she swallowed and bent from the waist to continue tying up cornstalks. Large ochre squashes sat plumply in fields of withering vines; people priming pumps and swinging buckets out of wells on long poles; tall narrow haystacks, and pepper fields in so many stages of ripeness I first took them for flower gardens. It is a feeling of utter quietness, deep rural isolation the train briefly penetrates. It goes on without a change for hours, this afternoon in Yugoslavia, and then all people disappear and the effect is eerie: roads without cars or bicycles, cottages with empty windows at the fringes of empty fields, trees heavy with apples and no one picking them. Perhaps it's the wrong time – 3.30; perhaps it's too hot. But where are the people who stacked that hay and set those peppers so carefully to dry? The train passes on – that's the beauty of a train, this heedless movement – but it passes on to more of the same. Six neat beehives, a derelict steam engine with wild flowers garlanding its smokestack, a stalled ox at a level crossing. In the heat haze of the afternoon my compartment grows dusty, and down at the front of the train Turks lie all over their seats sleeping with their mouths open and children wakeful on their stomachs. At each river and bridge there were square brick emplacements, like Croatian copies of Mar-tello towers, pocked by bombs. Then I saw a man, headless, bent over in a field, camouflaged by cornstalks that were taller than he; I wondered if I had missed all the others because they were made so tiny by their crops. There was a drama outside Nis. At a road near the track a crowd of people fought to look at a horse, still in its traces and hitched to an overloaded wagon, lying dead on its side in a mud puddle in which the wagon was obviously stuck. I imagined its heart had burst when it tried to free the wagon. And it had just happened: children were calling to their friends, a man was dropping his bike and running back for a look, and farther along a man pissing against a fence was straining to see the horse. The scene was composed like a Flemish painting in which the pissing man was a vivid detail. The train, the window frame holding the scene for moments, made it a picture. The man at the fence flicks the last droplets from his penis and, tucking it in his baggy pants, begins to sprint; the picture is complete.

'I hate sightseeing,' said Molesworth. We were at the corridor window and I had just been reprimanded by a Yugoslav policeman for snapping a picture of a steam locomotive that, in the late afternoon sun, and the whirling dust the thousands of homeward-bound commuters had raised crossing the railway lines, stood amidst a magnificent exhalation of blue vapours mingling with clouds of gold gnats. Now we were in a rocky gorge outside Nis, on the way to Dimitrovgrad, the cliffs rising as we moved and holding occasional symmetries, like remainders of intelligent brickwork in the battlements of a ruined castle. The sight of this seemed to tire Moles-worth, and I think he felt called upon to explain his fatigue. 'AH that tramping around with guidebooks,' he said after a moment. 'In those horrible crocodiles of tourists, in and out of churches, museums, and mosques. No, no, no. I just like to be still, find a comfortable chair. Do you see what I mean? I like to absorb a country.'

He was drinking. We were both drinking, but drink made him reflective and it made me hungry. All I had had to eat during the day was a cheese bun in Belgrade, an envelope of pretzels, and a sour apple. The sight of Bulgaria, with its decrepit houses and skinny goats, did not make me hopeful of a good meal at Sofia Station, and at the fearfully named town of Dragoman a number of people, including several from Car 99, were taken off the train because they hadn't had cholera shots. Italy, the Bulgarians said, was stricken.
