Neither are their steep and Hilly Lands uncapable of being thus overflown with Water.

For the doing of which they use this Art.

They level these Hills into narrow Allies, some three; some eight foot wide one beneath another, according to the steepness of the Hills, working and digging them in that fashion that they lye smooth and flat, like so many Stairs up the Hills one above another.

The Waters at the top of the Hills falling down wards are let into these Allies, and so successively by running out of one into another, water all; first the higher Lands, and then the lower.

The highest Allies having such a quantity of Water as may suffice to cover them, the rest runs over unto the next, and that having its proportion, unto the next, and so by degrees it falls into all these hanging parcels of Ground.
