Island at Woburn Abbey

The island, the bays, and the channels described on the map and in the drawings, would also contribute to improve the shape of this pool; while the plantations, suggested on the head, would hide the low ground beyond it: for, although water, in nature, is really on high ground, yet, in appearance, it fills the lowest place, because we seldom see ground below the water; either the descent is so gradual, or the obstruction so bold, as to conceal the different levels, and deceive the sight.
