On every side jets of water rose like park fountains, out of a sea of vapor; some of them continuous, others intermittent, as if a capricious Pluto controlled their movements. They rose like an amphitheater on natural terraces; their waters gradually flowed together under folds of white smoke, and corroding the edges of the semi-transparent steps of this gigantic staircase. They fed whole lakes with their boiling torrents.

Farther still, beyond the hot springs and tumultuous geysers, came the solfataras. The ground looked as if covered with large pustules. These were slumbering craters full of cracks and fissures from which rose various gases. The air was saturated with the acrid and unpleasant odor of sulphurous acid. The ground was encrusted with sulphur and crystalline concretions. All this incalculable wealth had been accumulating for centuries, and if the sulphur beds of Sicily should ever be exhausted, it is here, in this little known district of New Zealand, that supplies must be sought.
