It was therefore of great importance to secure the supply of the cure. In 1860, a British expedition to South America led by Clements Markham smuggled back cinchona seeds and plants, which were introduced in several areas of British India and Sri Lanka. In India, it was planted in Ootacamund by William Graham McIvor. In Sri Lanka, it was planted in the Hakgala Botanical Garden in January 1861. James Taylor, the pioneer of tea planting in Sri Lanka, was one of the pioneers of cinchona cultivation. By 1883, about  were in cultivation in Sri Lanka, with exports reaching a peak of 15 million pounds in 1886. The cultivation (initially of C. succirubra (now C. pubescens) and later of C. calisaya) was extended through the work of George King and others into the hilly terrain of Darjeeling District of Bengal. Cinchona factories were established at Naduvattam in the Nilgiris and at Mungpoo, Darjeeling, West Bengal. Quinologists were appointed to oversee the extraction of alkaloids with John Broughton in the Nilgiris and C.H. Wood at Darjeeling. Others in the position included David Hooper and John Eliot Howard.
  In 1865, "New Virginia" and "Carlota Colony" were established in Mexico by Matthew Fontaine Maury, a former Confederate in the American Civil War. Postwar Confederates were enticed there by Maury, now the "Imperial Commissioner of Immigration" for Emperor Maximillian of Mexico, and Archduke of Habsburg. All that survives of those two colonies are the flourishing groves of cinchonas established by Maury using seeds purchased from England. These seeds were the first to be introduced into Mexico.
  The cultivation of cinchona led from the 1890s to a decline in the price of quinine, but the quality and production of raw bark by the Dutch in Indonesia led them to dominate world markets. The producers of processed drugs in Europe (especially Germany), however, bargained and caused fluctuations in prices, which led to a Dutch-led Cinchona Agreement in 1913 that ensured a fixed price for producers. A Kina Bureau in Amsterdam regulated this trade.
