Chap. 131. The tide and stream flowing against each other.
THe reason the tide flows against the stream a of River, is, that the quantity of sea water forceth through the stream, and the descent of the river forceth the stream to passe through the motion, or rather by the motion of the tide, for the natural motions of all waters being to flow, and the force of the des∣cent added therto, gives it a double, if not a treble strength, so that when the force of the tide, and the force of the stream meets, and incounters, they make passes, as Duellers that fight hand to hand; but if one water runs quite through another, it is most probable that the tide runs through the stream, by reason it is armed strongly with salt, which may cause it to be stream∣proof, when the river water is porous, and weak by reason it is fresh, and thin as I may say.
