The Man Who Loved China (15 page)

In another embassy Chevrolet truck would be Sir Eric Teichman, who was being driven to a northern Chinese border city so that he could head west on another epic overland journey toward India, from where he would eventually fly home to Britain. The departure date for the two vehicles was set for August 7, a Saturday. It was expected that on this, their first Chinese adventure, the party would be staying away from base for eight weeks or so, little more.

 

For the duration of their expedition the Dunhuang caves were at the front of their minds: reaching them was the ultimate goal, no matter what the hardships. But there were other things to see on the way—other Chinese marvels. The first of these, which Needham managed to visit just a week after he left Chongqing, involved a subject that has captivated China since the beginnings of its history: water.

China is, basically, a gigantic plateau. tilted gently from west to east. The biggest of the Chinese rivers, the catchment of nearly all others, flow almost entirely in that general direction, from their sources in the Himalayas in the west to their estuaries on the eastern ocean. The rivers swell each springtime as a result of the melting snows and soon afterward become swollen again with rains during the southern monsoon. As a result, questions related to flooding and water control became, almost from the nation's beginnings, a matter of overarching importance.

And this was not just local importance. The Chinese had long ago realized that, so far as flooding was concerned, local interests had to be subordinated to a wider national need. Swollen rivers did their damage or brought their benefits to huge tracts of land and to large numbers of people who, if they were prudent, and whatever their local loyalties, ought to come together to bring each river under control. So the creation of what one might call a supra-local national water authority, and a large bureaucracy to populate it, became of great importance early on in China's history.

As it happened, the immense power that such a body eventually acquired in early China helped to strengthen the fledgling imperial system as a whole—and it quickly became evident that whoever controlled the empire's rivers simultaneously wielded enormous power over the empire. Some sinologists go farther: the historically despotic nature of Chinese imperial rulers derived from one abiding reality—that the keepers of China's hydraulics had the wherewithal to do with China much as they pleased.

Water engineers were given formidable powers, and when they were successful, they earned formidable reputations. One of these engineers, in the Qin dynasty, was Li Bing, who created a monster irrigation project on the Min River 2,300 years ago: astonishingly, it still stands. Part of Needham's plan when he set out that August was to inspect this structure: it was to be his introduction to the fact that ancient China could not only do small things very well—such as grafting plums and inventing the abacus and the magnetic compass—but also make achievements on a gargantuan scale.

Getting to the dam site turned out to be agonizingly slow. The men and Miss Liao traveled through the heat and dust of the Red Basin as slowly as sloths. Within the first moments of leaving Chongqing, they had been presented with a sight that unsettled their Chinese drivers. A funeral cortege passed directly in front of Sir Eric Teichman's truck. It turned out that the chairman of the Chinese Republic, Lin Sen, had died the previous week, and while climbing a hill on the way out of town the little convoy was forced to stop and wait for an hour as the white-robed mourners edged by. Teichman's driver complained that this was an omen: so somber a delay must mean that his journey—maybe everyone's journey—was ill-fated.

The village of Yongqiang, which now is just a ten-minute drive west of Chongqing, took Needham and his trucks took more than eight hours to reach. By the time the sun was setting on Saturday evening his little convoy had bumped and strained over only sixty miles, reaching the town of Neijiang. They stayed that night at the China Travel Service inn, which

Whether his own clothes caught fire or his truck broke down—it was already leaking oil, and the radiator was dripping—we do not know, but Needham made no progress on Sunday. He opted instead to meet and have dinner with a Chinese cavalry colonel whose card he had been given, who turned out to have been educated at Saumur, and who spoke impeccable French. On Monday morning Needham went on a side trip to buy fuel—ninety gallons of power alcohol and an additional ten gallons of absolute alcohol, which he planned to cut with some low-octane gasoline he had bought in Chongqing. He irritatedly described the road toward the distant blue mountains as “rough going,”

though he was charmed to find someone selling sugar plums. He also bought apples and a basket of tomatoes, then managed to avoid the normally compulsory police check on the main northbound road, arriving in Chengdu just before suppertime, just in time to allow his mechanic to rush the flagging truck to a repair shop.

Then finally the blue range of mountains stood ahead, rising abruptly before them, with the Min River coursing out of a chasm with terrific speed. Needham knew the most important statistics—that the Min fell 12,000 feet from its headwaters in only 400 miles, so that it flowed down an average gradient of thirty feet every mile, which in riverine terms is a formula for exceptional danger. He knew also that in 250 BC the redoubt
able Li Bing had worked to tame and harness the Min, creating the structure that stood before him now, which visitors before and since have felt should be listed as one of the wonders of the world.

The site is called Dujiangyan. As an irrigation project, it may not seem to deserve being ranked alongside the Pyramids or the Taj Mahal, but it is actually one of mankind's more extraordinary achievements. Needham liked to quote, approvingly, the ancient Roman engineer Sextus Julius Frontinus, who wrote famously in the first century after Christ that his aqueducts were indispensable, and would be remembered long after “the idle pyramids, or the useless, though famous, works of the Greeks.”

Needham liked this quotation not simply because Frontinus was right about the Egyptians and the Greeks but also because his achievements in Rome had been made three full centuries
after
those of Li Bing in China. Moreover, unlike the highfalutin monuments beside the Nile and the Yamuna, Dujiangyan had been made purely for the common good, and it still works today just as it was designed to work, whereas many Roman aqueducts lie in ruins. The fact that Dujiangyan was still working excited Needham most.

In 250 BC Li Bing had been appointed governor of the province of Shu—modern-day Sichuan—under the kingdom of Qin, during the unstable period of the so-called Warring States, and shortly before the formation of the unified Qin dynasty, from which the name
China
is derived. Like everyone, he was only too well aware of the Min's deadly caprices. It was a river that either ran half-dry in the summer, leaving the paddy farmers of the plains starved for water, or else, more commonly, flooded uncontrollably and caused a swath of destruction and death all the way to Chengdu and beyond. The river needed to be brought to heel. Li Bing, after winning permission from the king of Qin, undertook what would in time be described as “the largest and most carefully planned public works project yet seen anywhere in the eastern half of the Eurasian continent.”

To control the river, he decided to cut a new spillway and channel any excess water through it with a specially designed, adjustable diversion dam. It took him seven years to break through the mountain: he managed this by having workers burn piles of hay on the surface of rocks to make them hot, and then pour cold water to cool them down rapidly, letting the nearly
instant contraction crack them open. This cutting eventually led to an opening seventy feet wide, and the Min River waters, which were shifted toward it by Li Bing's clever fish-shaped dam, began to course through it the moment the final wall was broken open. The anniversary is still celebrated each year: a ceremony called the “breaking of the waters” is held every summer, commemorating an eastern engineering feat that was undertaken more than 2,000 years ago, when westerners (though not Plato, Aristotle, the Egyptians, or the Mesopotamians) still coated themselves with woad and did little more than grunt.

Needham was fascinated by what he found at Dujiangyan. The engineering achievement was astonishing, its design was aesthetically pleasing, and its long endurance was remarkable. He also loved the architecture of the temples that had been built on the hillsides centuries ago to commemorate Li Bing's work. He spent several pleasant hours gazing down at the river from a cool vantage point high on one of the pagodas in the forest.

Then he met the modern director of the irrigation scheme, who was technically Li Bing's successor. He encountered him walking around in the wet mist beside the main spillway, checking monitoring devices and reading water meters. He had a slide rule sticking out of his pocket and turned out to have been trained in Manchester. Needham said how impressed he was by the system—the spillway, the dams, the endless torrents of water—and all of it created so long ago. No wonder, he said, that they had erected a temple to Li Bing. “To us,” replied the director, smiling, “he was like a god. He surely deserved a temple.”

 

Needham now turned north. His plan was to cross an outlier of the mountain range and head northwest to join the Silk Road—a route that could take him, in theory, all the way to Baghdad and to the Mediterranean at Antioch. Even this fairly modest leg of the journey turned out to be wretchedly difficult. His diary pages for the second and third weeks of August are filled with references to breakdowns, interminable waits, and unexpected disasters—interspersed, however, with a jocular perspicacity, as if despite the frustration he finds it all rather amusing and instructive:

Needham's enjoyment stemmed from his discovery that the bishop was Roman Catholic and conducted high mass each Sunday, in Latin. Needham and H. T. went along, Needham finding himself open-mouthed with delight—at seeing the entirely Chinese congregation lip-synching the Latin recitatives, and most of all at listening to sacred music he had last heard in his little church in Thaxted. He said he felt transported, back to medieval Europe, and back to Essex in the 1930s.

But Needham's greatest annoyance was the growing frequency of not being transported. At times his litany of woes—as when he tried to cross the Bao River, ten days out from Chongqing—would become a full-blown chorus:
