Robert Clement Sconce Bunbury, Popular Science Monthly (1879)
“ All the pools have their distinctive character: some are very active, others sullen; some pretty, bubbling, shallow basins, others dark deep blue of endless depth; some bright and clear as crystal, others milky, or of mud of various consistency; some blowing off steam like fifty steam-engines, and many, alas! very many, smelling beyond the power of words to describe. It is curious how quickly one gets accustomed to the ceaseless sound of boiling water, or the dull, soughing sound of boiling mud that one hears on all sides, often without being able to see the hole whence it comes. ”
