Cascade/Cataract/Waterfall
History
Cascade, cataract, and waterfall were terms used interchangeably to designate a water feature, either natural or artificial, that was part of a designed landscape. These terms, which were synonymous, were in common usage and garden literature by the beginning of the eighteenth century. Only Noah Webster’s dictionary (1828) made any distinction among them, stating that the cataract was a cascade on a large scale. The more frequent synonymous usage of the terms is found in A. J. Downing’s essay on Montgomery Place (1847), where he entitled a section, “The cataract,” but then used the term “waterfall” in the text that followed.
This garden feature was achieved either by incorporating a preexisting waterfall into the garden scheme, by enhancing a small falls with the addition of rocks, or by building a completely artificial cascade. Directions for constructing cascades suggest that they were features that could be built on a range of scales, suitable for small gardens, large estates, and public waterways such as Fairmount Waterworks in Philadelphia. J. C. Loudon (1826), in his usual practical way, wrote that the only requirement was a wall to interrupt the flow of a stream or rivulet, causing the water to fall noisily over rocks and uneven surfaces.
The literature often describes waterfalls as part of the view beyond the garden proper. Visitors to Gray’s Garden in Philadelphia in the late eighteenth century, for example, recalled moving from the garden into the wilderness, where the falls of the Schuylkill were enjoyed before winding back to the garden [Fig. 1]. Downing offered descriptions of several cataracts that were illustrated by Alexander Jackson Davis, including those found at Montgomery Place [Fig. 2] and Blithewood [Fig. 3]. Located in the Hudson River Valley, these cataracts were connected to the designed landscape by the addition of paths, summerhouses, rustic furniture, and bridges. Although it often preexisted the garden, the cascade played a role in the experience of surprise and variety belonging to both the designed and naturally picturesque landscape [Fig. 4]. The feature also could serve as a compositional terminus, as noted by the writer Constantia (1790).
Visitors often described the cascade as one of the most important elements in the sensory experience of the garden since it combined sound, which broke the silence, with the movement and vitality caused by the action of the falling water and its cooling spray. Downing, for example, noted that “[t]his valley is musical with the sound of waterfalls.” The sounds of crashing and gurgling water frequently preceded the view of the cascade, adding suspense to the catalogue of sensations felt by the visitor as he or she walked through the garden.
The question of taste was an issue as well; George William Johnson (1847) noted that a cascade was agreeable “only when properly associated with the scenery around.” The cascade or waterfall in the garden was an important element of the landscape because of the numerous associations it evoked. The cascade at Tivoli, the fountains of Versailles, Virginia Waters at Windsor, were all icons of European garden design that many designers sought to emulate. Others knew cascades such as Great Falls, Va., and Niagara Falls, N.Y., as America’s natural wonders, and writers such as Thomas Jefferson used these sites as proof of the bounty and sublimity of the new nation.

- “afew feet below the spring level the ground 40 or 50 f. sq. let the water fall from the spring in the upper level over a terrace in the form of a cascade. then conduct it along the foot of the terrace to the Western side of the level, where it may fall into a cistern under a temple, from which it may go off by the western border till it falls over another terrace at the Northern or lower side. let the temple be raised 2. f. for the first floor of stone. under this is the cistern, which may be a bath or anything else. the 1st story arches on three sides; the back or western side being close because the hill there comes down, and also to carry up stairs on the outside. the 2d story to have a door on one side, a spacious window in each of the other sides, the rooms each 8. f. cube; with a small table and a couple of chairs. the roof may be Chinese, Grecian, or in the taste of the Lantern of Demosthenes at Athens.”
- Jefferson, Thomas, April 1786, describing Hagley, property of Lord Wescot, England (1944: 113) [2]
- “Hagley, now Lord Wescot’s.—One thousand acres: no distinction between park and garden— both blended, but more of the character of garden. . . . This garden occupying a descending hollow between the Clent and Witchbury hills, with the spurs from those hills, there is no level in it for a spacious water. There are, therefore, only some small ponds. From one of these there is a fine cascade; but it can only be occasionally, by opening the sluice. This is in a small, dark, deep hollow, with recesses of stone in the banks on every side. In one of these is a Venus predique, turned half round as if inviting you with her into the recess. There is another cascade seen from the portico on the bridge.”
- Cutler, Rev. Manasseh, 14 July 1787, describing Gray’s Tavern, Philadelphia, Pa. (1987: 1:276–77) [3]
- “When we came to the fence, we were delightfully astonished with the view of one of the finest cascades in America, which presented itself directly before us at the further end of the opening. A broad sheet of water comes over a large horizontal rock, and falls about seventy feet perpendicular. It is in a large river, which empties into the Schuylkill just above us. The distance we judged to be about a quarter of a mile, which being seen through the narrow opening in the tall grove, and the fine mist that rose incessantly from the rocks below, had a most delightful effect. Here we gazed with admiration and pleasure for some time, and then took a different route in our return through the grove, and followed a walk that led down toward the Schuylkill.”

- “I propose in this map, of leting the [Ti]ber return in its proper channel by a fall which issuing from under the base of the Congress building may there form a cascade of forty feet heigh or more than one hundred waide which would produce the most happy effect in rolling down to fill up the canall and discharge itself in the Potowmack of which it would then appear as the main spring when seen through that grand and majestic avenue intersecting with the prospect from the palace at a point which being seen from both I have designated as the proper for to erect a grand Equestrian figure.”
- Jefferson, Thomas, 1804, describing Monticello, plantation of Thomas Jefferson, Charlottesville, Va. (quoted in Nichols and Griswold 1978: 111) [6]
- “The spring of Montalto [Carter’s Mountain] either to be brought to Monticello by pipes or to fall over steps of stairs in cascade, made visible at Monticello through a vista.”
- Anonymous, 1826, describing the Friends Asylum for the Insane, near Frankford, Pa. (Hawkins 1991: 79) [7]
- “A shaded, serpentine walk, now skirting the edge of the wood, now plunging into its dark and dependent foliage, and embracing, in its windings, more than a mile, leads over a neat and lightly constructed bridge, to a pleasure house, which might justly termed the Temple of Solitude. It is securely founded on a rock, which juts abruptly forth from the declivity of a steep hill, three sides of which are almost perpendicular, and of considerable height. A chasm, formed by nature, in the rock, to the left of the entrance, affords, with the assistance of stones transversely arranged, a descent to the small valley beneath. The straight and towering tulip tree, the sturdy oak, the chestnut, and the beech, cast their cool shadows around this wood-embosomed abode of contemplation. A rapid stream ripples over the rocks, at a few yards distance, producing the melancholy, but pleasing sounds of a distant waterfall.”
- Trollope, Frances Milton, 1830, describing Fairmount Waterworks, Philadelphia, Pa. (1832: 2:42–43) [8]
- “The water-works of Philadelphia have not yet perhaps as wide extended fame as those of Marley [at Versailles], but they are not less deserving it. . . . It is, in truth, one of the very prettiest spots the eye can look upon. A broad wear is thrown across the Schuylkill, which produces the sound and look of a cascade.” [Fig. 5]
- Thacher, James, 26 November 1830, “An Excursion on the Hudson,” describing the garden of Col. Thaddeus Kosciusko, West Point, N.Y. (New England Farmer 9: 148) [9]
- “Among the interesting recollections pertaining to West Point is Kosciusko’s garden, situated in a deep rocky valley near the river, where in 1778, I was amused in viewing his curious water fountain, spouting jets and cascades. ‘Clusters of lilacs are still growing which are said to have been planted by the Polish Patriot.’”

- “This avenue to the mansion is over a stone bridge, crossing a rapid stream precipitated from the milldams above, and falls in a cascade below. The winding of the road, the varied surface of the ground, the bridge, and the falling of the water, continually vary the prospect and render it a never tiring scene.”

- “He takes another path, passes by an airy looking rustic bridge, and plunging for a moment into the thicket, emerges again in full view of the first cataract. Coming from the solemn depths of the woods, he is astonished at the noise and volume of the stream, which here rushes in wild foam and confusion over the rocky fall, forty feet in depth. Ascending a flight of steps made in the precipitous banks of the stream, we have another view, which is scarcely less spirited and picturesque.
- “This waterfall, beautiful at all seasons, would alone be considered a sufficient attraction to give notoriety to a rural locality in most country neighborhoods. But as if nature had intended to lavish her gifts here, she has, in the course of this valley, given two other cataracts. These are all striking enough to be worthy of the pencil of the artist, and they make this valley a feast of wonders to the lovers of the picturesque.”
- Downing, A. J., October 1847, describing Montgomery Place, country home of Mrs. Edward (Louise) Livingston, Dutchess County, N.Y. (quoted in Haley 1988: 52) [10]
- “On its [the lake] northern bank is a rude sofa, formed entirely of stone. Here you linger again, to wonder afresh at the novelty and beauty of the second cascade. The stream here emerges from a dark thicket, falls about twenty feet, and then rushes away on the side of the peninsula opposite the lake.”

The construction of the waterfall, where avowedly artificial, is nothing more than a strong-built wall across the stream, perfectly level at top, and with a strong, smooth, accurately fitted, and well jointed coping. . . . Where a natural waterfall is to be imitated, the upright wall must be built of huge irregular blocks; the horizontal lamina of water broken in the same way by placing fragments of rocks grouped here and there so as to throw the whole into parts; and as nature is never methodical, to form it as if in part a cascade....
- “1827. In imitating a natural cascade in garden-scenery, the horizontal line must here also be perfect, to prevent waste of water in dry seasons, and from this to the base of the lower slope the surface must be paved by irregular blocks, observing to group the prominent fragments, and not distribute them regularly over the surface. . . .

The greatest danger in imitating cascades and waterfalls, consisting in attempting too much, a very few blocks, disposed with a painter’s eye, will effect all that can be in good taste in most garden-scenes; and in forming or improving them in natural rivers, there will generally be found indications both as to situation and style, especially if the country be uneven, or stony, or rocky. . . .

- “CASCADE, or Waterfall, is an important adjunct in landscape gardening, but agreeable only when properly associated with the scenery around; that association is a bold broken ground, and a dense plantation of trees; nothing is more misplaced or tasteless than a sheet of water falling into another uniform collection of water, in an open unwooded plain. Mr. Whateley justly observes, that ‘a rill cannot pretend to any sound beyond that of a little waterfall; the roar of a cascade belongs only to larger streams: but it may be introduced by a rivulet to a considerable degree, and attempts to do more have generally been unsuccessful; a vain ambition to imitate nature in her great extravagancies betrays the weakness of art. Though a noble river throwing itself headlong down a precipice be an object truly magnificent, it must however be confessed, that in a single sheet of water there is a formality which its vastness alone can cure, but the height, not the breadth is the wonder: when it falls no more than a few feet, the regularity prevails, and its extent only serves to expose the vanity of affecting the style of a cataract in an artificial cascade; it is less exceptionable if divided into several parts, for then each separate part may be wide enough for its depth; and in the whole, variety, not greatness, will be the predominant character. But a structure of rough, large, detached stones cannot easily be contrived of strength sufficient to support a great weight of water, it is sometimes from necessity almost smooth and uniform, and then it loses much of its effect: several little falls in succession are preferable to one greater cascade, which in figure, or in motion, approaches to regularity.
- “‘When greatness is thus reduced to number, and length becomes of more importance than breadth, a rivulet vies with a river, and it more frequently runs in a continued declivity, which is very favourable to such a succession of falls. Half the expense and labour which are sometime bestowed on a river to give it at the best, a forced precipitancy in any one spot only, would animate a rivulet through the whole of its course; and after all the most interesting circumstance in falling waters, is their animation: a great cascade fills us with surprise, but all surprise must cease; and the motion, the agitation, the rage, the froth, and the variety of the water are finally the objects which engage the attention; for these a rivulet is sufficient, and they may there be produced without that appearance of effort which raises a suspicion of art. To obviate such a suspicion, it may sometimes be expedient to begin the descent out of sight; for the beginning is the difficulty: if that be concealed, the subsequent falls seem but a consequence of the agitation which characterizes the water at its first appearance, and the imagination is, at the same time, let loose to give ideal extent to the cascades; when a stream issues from a wood, such management will have a great effect, the bends of its course in an open exposure may afford frequent opportunities for it, and sometimes a low broad bridge may furnish the occasion, a little fall hid under the arch will create a disorder, in consequence of which, a greater cascade below will appear very natural.’ . . .
- “FOUNTAINS. . . .
- “Drooping fountains, or such as bubbling from their source trickle over the edge of rocks, shells, or vases, combining the cascade with the fountain, are capable of much greater beauty.”
- Downing, A. J., 1849, A Treatise on the Theory and Practice of Landscape Gardening (p. 364) [23]
- “Cascades and water-falls are the most charming features of natural brooks and rivulets. Whatever may be their size they are always greatly admired, and in no way is the peculiar stillness of the air, peculiar to the country, more pleasingly broken, than by the melody of falling water. . . . Now any one who examines a small cascade at all attentively, in a natural brook, will see that it is often formed in the simplest manner by the interposition of a few large projecting stones, which partially dam up the current and prevent the ready flow of the water. Such little cascades are easily imitated.”
