Cascade
or WATERFALL. This, says Loudon, 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 the use of cement; and next by 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 plantations. Where running water is conducted in the forms belonging to the geometric style of gardening, Cascades are constructed in the form of crescents, flights of steps, or wavy slopes, all of which produce excellent effects when appropriately introduced.
