In the twelfth year of the Xianfeng Emperor, rain inundated Gold Mountain. It started raining in the third month of the autumn, the usual start of the rainy season on this part of the coast of Yingzhou, but then it never stopped raining until the second month of the following spring. It rained every day for half a year, and often a pounding, drenching rain, as if it were the tropics. Before that winter was halfway over the great central valley of Gold Mountain had flooded up and down its entire length, forming a shallow lake fifteen hundred li long and three hundred li wide. The water poured brownly between the green hills flanking the delta, into the great bay and out of the Gold Gate, staining the ocean the colour of mud all the way out to the Peng lai Islands. The outflow ran hard both ebb and flood, but still this was not enough to empty the great valley. The Chinese towns and villages and farms on the flat valley floor were drowned to the rooftops, and the entire population of the valley had to leave for higher ground, in the coastal range or the foothills of the Gold Mountains, or, for the most part, down to the city, fabled Fangzhang. Those who lived on the eastern side of the central valley tended to move up into the foothills, ascending the rail and stage roads that ran up through apple orchards and vineyards, overlooking the deep canyons that cut between the tablelands. Here they ran into the large foothill population of Japanese.
Many of these Japanese had come in the diaspora, after the Chinese armies had conquered Japan, in the Yung Cheng dynasty, a hundred and twenty years before. They were the ones who had first begun to grow rice in the central valley; but after only a generation or two, Chinese immigration filled the valley as the rains were now filling it, and most of the Japanese nisei and sansei moved up into the foothills, looking for gold, or growing grapes and apples. There they encountered a fair number of the old ones, hidden in the foothills and struggling to survive a malaria epidemic that recently had killed most of them off. The Japanese got along with the survivors, and the other old ones that came from the east, and together they resisted Chinese incursions into the foothills in every way they could, short of insurrection; for over the Gold Mountains lay high desolate akaline deserts, where nothing could live. Their backs were to the wall.
So the arrival of so many Chinese refugee farming families was no very happy event for those already there. The foothills were composed of plateaux tilted up towards the high mountains, and cut by very deep, rugged, heavily forested river canyons. These manzanita choked canyons were impenetrable to the Chinese authorities, and hidden in them were many Japanese families, most of them panning for gold or working small diggings. Chinese road building campaigns stuck to the plateaux for the most part, and the canyons had remained substantially Japanese, despite the presence of Chinese prospectors: a Hokkaido-in exile, tucked between the Chinese valley and the great desert of the natives. Now this world was filling with soaked Chinese rice farmers.
Neither side liked it. By now bad relations between Chinese and Japanese were as natural as between dog and cat. The foothill Japanese tried to ignore the Chinese setting up refugee camps by the all the stage and railway stations; the Chinese tried to ignore the Japanese homesteads they were intruding on. Rice ran low, tempers got short, and the Chinese authorities sent troops into the area to keep order. The rain kept falling.
One group of Chinese walked out of the flooding on the stage road that followed the course of Rainbow Trout River. Overlooking the river's north bank were apple orchards and cattle pasturage, mostly owned by Chinese in Fangzhang, but worked by Japanese. This group of Chinese camped in one of the orchards, and did what they could to construct shelter from the rain, which continued to fall, day after day after day. They built a pole framed barnlike building with a shingle roof, an open fire at one end and mere sheets for walls; meagre protection, but better than none. By day the men scrambled down the canyon walls to fish in the roaring river, and others went into the forest to hunt deer, shooting great numbers of them and drying their meat.
The matriarch of one of these families, Yao Je by name, was frantic that her silkworms had been left behind on their farm, in boxes tucked in the rafters of her filature. Her husband did not think there was anything that could be done about it, but the family employed a Japanese servant boy named Kiyoaki, who volunteered to go back down to the valley and take their rowing boat out on the first calm day, and recover the silkworms. His master did not like the proposal, but his mistress approved of it, as she wanted the silkworms. So one rainy morning Kiyoaki left to try to return to their flooded farm, if he could.
