Chap. 16.—Folio 108.
TReats of RIVERS in General. That Torrents and Rivulets sometimes proceed from a quantity of Rain, and dissolved Snow. That most Rivers proceed from Fountains; but great Rivers have their original, either from the Congress of many Rivulets, and small Ri∣vers; or flow from Lakes and Marishes. That Rivers are very much augmented by frequent Rains, and dissolved Snow, and that in divers Seasons and Months of the Year. From whence Rivers are generated; and what may be the Original of that Water which floweth from Springs. That certain Rivers hide themselves in the midst of their passage under the Earth, and in another place rise up again, as it were new Rivers; and all Rivers do discharge themselves into the Sea, or else the one into the other, which at last emp∣tieth it self into the Sea. The reason why no Salt-Water Rivers are found, seeing that Salt Springs are found in many places. The reason why Rivers have, or acquire a greater Latitude in one part of them, than in another; and why some run with a more swift Current, and others with a more slow. Also why one River is car∣ried with a swift Current in once place, and a slow in another. That most Rivers have their Course in divers windings. The Water of Rivers carrieth with it many particles of various Metals, Minerals, Sands, and Oily, fat Bodies; and that the Waters of most Rivers differ in colour, gravity and other qualities. That some Rivers at a certain time every Year, are so augmented, that they over flow the adjacent Lands. The Rea∣son how Springs and Fountains break forth. Rules to know if a Spring or Well may be made there, and to know if the Water is good. That Whirl∣pools are found in the Channels of some Rivers. That River-Water is more light than that of the Sea.
