they practically ignore Chinese rule, paying tribute and intermarrying with the mountaineers, from whom they have also obtained large tracts of land. ~PRODUCTIONS OF FORMOSA.~ Maize, potatoes, fruits, tobacco, indigo, sugar, rice, and tea, are all grown on this island, the three latter in rapidly increasing quantities for purposes of export. Of natural products salt, coal, sulphur, petroleum, and camphor are of the first importance. The vast coal basins have hardly been opened or even explored, the only mines now worked being those in the northern part, near Kilung. Native methods of mining are, however, the only ones employed thus far, and it is not surprising, considering their extreme simplicity, that they have not been able to extract coal from remote districts, where the natural difficulties encountered are greatest. Hand labor alone is used, and draining a pit unheard of--compelling a speedy abandoning of the mines when pierced to any great depth in the mountain side. The cost of the coal at the mouth of the pit is about 65 cents per ton for the first qualities, which price improved methods might reduce a third. The presence of volcanoes on this island will, nevertheless, present a serious obstacle to the employment of western mining machinery, especially along the coast, where the measures appear to be excessively dislocated and the work of draining is rendered more difficult. Petroleum is abundant in certain tracts of northern Formosa, flowing plentifully from crevices in the hills, and used to some extent for burning and medicinal purposes by the natives, but not exported. The possibilities of a large sulphur trade are much more important. It is brought from solfatarae and geysers at Tah-yu kang, near Kilung, where it is found in a nearly pure state, as well, too, as a great quantity of sulphurous acid which might with profit be used in the sugar refineries on the island. The manufacture of sulphur is, however, forbidden by treaty, though its exportation goes on in small quantities, the contractors taking on themselves all risk of seizure. Camphor, perhaps the greatest source of wealth to Formosa, is obtained here by saturating small sticks of the wood with steam, not by boiling as in Japan. The crystals of camphor condense in a receiver placed above the furnace; during the process of distillation an essential oil is produced, which when chemically treated with nitric acid becomes solid camphor. The trees from which the wood is cut grow in the most inaccessible tracts of the island, and are, according to all descriptions, of immense extent, though chopped down by the natives without discrimination or idea of encouraging a second growth.
