A waterfall or cascade in improvements

1527. A waterfall or cascade is an obvious improvement where a running stream passes through a demesne, and is to be formed by first constructing a bank of masonry, presenting an inclined plane to the current, and rendering it impervious to water by puddling or the use of proper cements, and next varying the ridge of the bank, and the bed of the river below it, with fragments of rock, so chosen and placed, as not to present a character foreign to what nature may be supposed to have produced there. The adjoining ground frequently requires to be raised at such scenes, but may be harmonised by a plantation.
