yellowish with a sulphureous matter and colour. The soil also, when it is touch'd by such as walk thereupon, sounds and rattles like a Drum, as it were, by reason of the concavities; and you may feel, as it were, not without astonishment, boyling waters under your feet, and thick and fired fumes, to hiss and flow hither and thither, with a great crackling noise, through Pipes and Subterraneous Ca∣verns, made by the force of the hot Exhalations. VVhich force, how great it is, you may try, by stopping any hole, with a heavy stone, or so; for then you shall see the violent force of the smoke presently to belch it forth again.
Yet an huge Laky-ditch in the same Plain did wonderfully affect me: For it is found full of boyling waters, and ready to fright one with their blackness. You would say, it was a Kettle or Caldron boy∣ling with Pitch and Rosin. VVhich forthwith changes place; and the waters growing hard on the brim of the Caldron, is made nar∣rower or wider, as the force and impetuousness of the Exhalation is greater or lesser.
That also is wonderful; That that swallowing Gulph, casts forth waters on high, eight or ten foot above a mans height, in the fashion of a Pyramid, and those fat and clayie, and almost of a sulphureous colour. VVhich even the Inhabitants of Putzol do confess; who affirm, that these boyling waters are shot forth on high, to sixteen, or even twenty four palm height sometimes. And this especially when the Sea rages; but not so likewise when it is calm. A most clear sign certainly, that these marvellous effects of the exalted liquor, pro∣ceed from no where else, but from the Sea: For the Sea being tossed with the storms of winds, whilst through subterraneous passages it sollicites, as it were, the Steward or dispenser of this melted liquid matter; 'tis no wonder, that a Liquor, not knowing how to contain it self in its own narrow bounds, should be darted forth on high, beyond its limits, constituted thereunto by nature. By so much in∣deed the more violently, by how much the impetuous afflux of the Sea thrusts it forth with greater violence. Yea, and the divers colour of the waters at that time; compounded of the various mixture of the Sea-water, with the various mixture of the Mineral Juices; Name∣ly, of those waters, which, from the more profound boyling Springs of the Earth, the subterraneous winds, agitated by the ragings of the Sea, and growing stronger and stronger amidst the slames, belch forth; does plainly teach. But the Sea being still calm, none of these things are perceiv'd; but the waters are only beheld sat, or
