In 1858 the great silver rush began in Napa Valley, and miners eagerly flocked to the eastern hills. In the 1860s, mining carried on, in a large scale, with quicksilver mines operating in many areas of Napa County. The most noted mine was the Silverado Mine, near the summit of Mount Saint Helena. The mine was immortalized by Robert Louis Stevenson in his classic "The Silverado Squatters". At this time, the first wave of rural, foreign laborers from coastal villages of China's Canton province arrived in California, and at Napa County mines. Global investment bankers and national trading companies, especially British, imported this first wave of workers to do the manual jobs needed to build the area's infrastructure. In contrast, the 49ers were often literate, Anglo-Americans "from the East" concerned about the rights of labor. Gold rush wages were high with California enjoying an "island" demand for workers. This condition set in motion a clash that resulted in the White Workingman's Party movement; Napa Valley vintner Charles Krug was treasurer of that party. The opportunistic "Socialist" Kearny led the Party to control the state government in the 1870s. These predominately Irish-German born newcomers eventually passed the "anti-stick" legislation that led to the 1882 Chinese Exclusion Act by the US Congress.
