The Boy Travellers in Australasia
(1889)
“ Close to the village are several mud-baths, where one may sit up to his neck in hot mud for hours, and then wash off the adhesive stuff in a neighboring pool. These solfataras, or mud-baths, are very numerous, and in many instances very dangerous. Where they are small the hot mud simply boils and bubbles, and slowly oozes out of the ground; and the chief danger lies in breaking through the crust near them and finding yourself plunged in the scalding mush. ”
