I was now face to face with the castle moat, which was, indeed, very wide and very deep. Alas! I could not swim, and my chance of escape seemed of a truth hopeless, as, doubtless, it would have been had I not espied a boat tied to the wall by a r...

used to bring the water to the main from both sides, but there is less
duplication of work when the main can be at one side of the wet land.
Branches of the main may be needed to reach remote parts of the area.
