Reading edition
Caron also speaks of these springs, some of which he describes as intermittent. Some are boiling hot, and their waters had been used, as we have seen, in the torture of the Catholics. They are all found in a volcanic mountain, having several craters which eject black sand and smoke. In the interior of the province of Higo, on the opposite shore of the gulf of Shimabara, is another volcano. The province of Satsuma is entirely volcanic, and off its southern extremity is an island that burns incessantly.—Klaproth, from Japanese authorities, “Asiatic Journal,” vol. xxx.
