We know that it is cultivated in Tonquin and Yunnan, but only to a limited extent, the product of these provinces being also of a very inferior quality. It is grown in Cochin-China and the mountain ranges of Ava, but only for local consumption, and that, while it is indigenous to the mountains, separating China from Burmah, it is not cultivated there for either export or profit, and although claimed by some authorities to be grown all over the Chinese empire, its cultivation for commercial purposes is confined to the region lying between the 24th and 35th degrees of north latitude, the climate between these parallels varying to a considerable extent, being much warmer in the southern than in the northern provinces. The districts in which it is chiefly cultivated, however, and from which it is principally exported, are embraced in the southwestern provinces of Che-kiang, Fo-kien, Kiang-see, Kiang-nan, Gan-hwuy Kwang-tung, some little being also produced for export in the western province of Sze-chuan. It is cultivated for commercial purposes all over the Japanese islands, from Kiusiu, in the south, to Niphon, in the extreme north, but the zone found most favorable to its most profitable production in these islands is that lying between the 30th and 35th degrees, more especially in the coast provinces of the interior sea. It is also grown to some extent in Corea, from which country—although claimed by some to be the original country of tea—none is ever exported. In the year 1826 some tea seeds were sent from Japan to Java and planted as an experiment in the residency of Buitenzorg, where they were found to succeed so well that tea-culture was immediately commenced on an extensive scale in the adjoining residencies of Cheribon, Preanger and Krawang, the number of tea trees in the former district amounting to over 50,000 in 1833. The several other districts of the island to which it had been extended, now containing upwards of 20,000,000 trees from which over 20,000,000 pounds of prepared tea are annually delivered to commerce, tea-culture forming one of the chief industries of the island at the present day.
