Lemon Hill was the Schuylkill River estate of the Philadelphia merchant Henry Pratt (1761–1838). Pratt purchased the property, which comprised the southern portion of Robert Morris’s (1734–1806) The Hills, in 1799. Under Pratt’s ownership, Lemon Hill was known for its geometric-style gardens and extensive greenhouse and hothouse complex. In 1855 Lemon Hill became part of the newly formed Fairmount Park, where the house still stands and operates as a historic site.

On March 15, 1799, Henry Pratt (1761–1838), a wealthy shipping merchant and land speculator from Philadelphia, purchased the southern portion of Robert Morris’s Schuylkill River estate, The Hills, at a sheriff’s sale. He renamed the property Lemon Hill, supposedly after the citrus trees that grew in Morris’s gardens, and built a new Federal-style villa to replace Morris’s house. Pratt maintained his primary residence within the city of Philadelphia, and Lemon Hill served mainly as a suburban retreat for entertaining friends and business associates.
Pratt also permitted members of the public to tour Lemon Hill. In 1830 a Committee of the Pennsylvania Horticultural Society remarked upon the estate’s popularity, reporting that “[f]ew strangers omit paying it a visit” (view text). Situated on a bluff above the east bank of the Schuylkill River, Lemon Hill afforded an “elegant and extensive” prospect of the river view text) [Fig. 1]. In 1813 one commentator proclaimed that the grounds were “in the highest state of cultivation” and praised Pratt’s “picturesque and ornamental improvements” view text). The Committee of the Pennsylvania Horticultural Society also commended Lemon Hill’s “picturesque effect,” with “water and wood...distributed in just proportions with hill and lawn and buildings of architectural beauty” (view text). Karl Bernhard, Duke of Saxe-Weimar, who visited the estate in 1825, was especially impressed by the “very handsome” chestnut and hickory trees as well as two very large tulip trees that ornamented the grounds ().
The gardens at Lemon Hill were elaborately designed, featuring a circular grotto and numerous summerhouses adorned with marble statues, goldfish ponds, fountains, cascades, and bowers (view text), as well as trellises, springhouses, and temples such as the one drawn by James Fuller Queen in 1840 (view text) [Fig. 2]. According to the Pennsylvania Horticultural Society, flower borders along the walks at Lemon Hill were interspersed with evergreens and flowering plants, including many exotic warm-weather varieties that were able to “bear the winter with a little straw covering” (view text). Writing in 1849, Andrew Jackson Downing claimed that Lemon Hill had been “the most perfect specimen of the geometric mode in America” during the 1820s, and that its gardens had exhibited “all the symmetry, uniformity, and high art of the old school” (view text). However, even decades before Downing penned these words, some already considered the geometric or French mode of landscape design to be old-fashioned; indeed, in 1816 the British naval officer Captain Joshua Rowley Watson complained that the grounds at Lemon Hill were “too much after the French manner of pleasure gardens” for his taste (view text).
The greenhouse and hothouses at Lemon Hill were said to be the largest of their kind in the United States and often dominate nineteenth-century depictions of the estate (view text) [Figs. 3–4]. The greenhouse had been a major feature of The Hills as well, and Pratt built upon Morris’s already significant investment when he acquired the property. In August 1799, several months after purchasing Lemon Hill at the sheriff’s sale, Pratt paid Morris $750 for greenhouse plants. Under Pratt’s ownership, the hothouses contained an enormous quantity and variety of plants, including many exotics. A June 1838 auction catalog of the contents of Lemon Hill’s greenhouses and hothouses lists 2,701 individual plants for sale, including various roses, carnations, geraniums, camellias, citrus, aloes, cactus, hydrangeas, and coffee trees, among many others kinds. Pratt invited the public to view his most rare specimens. In June 1821, for example, Pratt exhibited a flowering aloe—one of the plants he had purchased from Morris’s greenhouse—alongside “a considerable number of rare and beautiful tropical plants” at the Philadelphia’s Orphan’s Asylum as part of a fundraiser for the institution (view text). Pratt’s collection also won awards from The Pennsylvania Horticultural Society, including prizes for exhibiting the first mango as well as a particularly “splendid specimen” of poinsettia. In order to water the extensive collection of plants at Lemon Hill, Pratt installed a hydraulic water-delivery system, which pumped water up from the Schuylkill River to a series basins that supplied the green and hothouses ().
Caring for the groves, flower and vegetable gardens, and greenhouse plants at Lemon Hill required a large team of gardeners. According to an 1830 report by the Pennsylvania Horticultural Society, “For many years the chief gardener [at Lemon Hill] was assisted by eleven or twelve labourers,” but by 1830 that number had been reduced by about half, “probably owing to the finished condition” of the grounds at that time (view text). Although many of the skilled gardeners’ names remain unknown, we can identify three important members of Philadelphia’s horticultural community who worked at Lemon Hill early in their careers. It was to the “science and taste as a landscape gardener” of John McAran, who would later run a successful nursery and pleasure garden in Philadelphia, that the Pennsylvania Horticultural Society credited “the decorations of Lemon-Hill.” Robert Buist (1805–1880), another prominent Philadelphia nurseryman, worked briefly as a gardener at Lemon Hill shortly after emigrating from Scotland in 1828. Peter Mackenzie (1809–1865), a Scottish immigrant who had trained as a horticulturalist at London’s Kew Gardens, was the last head gardener employed by Pratt at Lemon Hill, working there after arriving to Philadelphia in 1827. While a gardener at Lemon Hill, Mackenzie earned the distinction, according to an article in The Magazine of Horticulture, of being “the first [in the United States] to flower the Poinsettia in superb condition.”
On February 29, 1836, Henry Pratt sold Lemon Hill to Knowles Taylor, a speculator and merchant, for $225,000. In an effort to take advantage of Lemon Hill’s proximity to the Schuylkill River and to the Philadelphia Columbia Railroad, Taylor and his fellow speculator Isaac Loyd, who had purchased the neighboring estate Sedgeley, made plans to develop a system of canals and wharves along the river (in much the same way that Thomas Mitchell had planned to do at The Woodlands just a few years earlier) and to construct high-density housing on the grounds of the two properties [Fig. 5]. However, the business partners went bankrupt before the plan could be put into action. When Lemon Hill went up for sale again in 1843, Thomas P. Cope (d. 1854), a prominent merchant and Select Councilman, proposed that the city should purchase the property and turn it into a public park in order to prevent future development along the Schuylkill River. Cope’s plan received the support of the College of Physicians, among other citizens’ groups concerned with the effects of pollution in the river, and the city of Philadelphia completed the purchase of Lemon Hill on July 24, 1844, for $75,000. Soon after this purchase, the Pennsylvania Historical Society offered to establish a garden at Lemon Hill, but the city rejected the proposal. Instead, in 1847, the city signed a ten-year lease with William Kern, an ice dealer, who sublet the estate to a tavern-keeper to be operated as a beer garden and public pleasure garden. In 1855, Ballou’s Pictorial Drawing-Room Companion described the boisterous atmosphere at the beer garden at Lemon Hill, characterizing the estate as “a favorite resort of the German population of Philadelphia...[who] assemble in large numbers to consume quantities of lager-bier, cheese, and other refreshments, and to amuse themselves with dancing...” [Fig. 6].
Within twenty years of Pratt selling Lemon Hill, the estate’s grounds—once described by A. J. Downing as “brilliant and striking”—had fallen into disrepair (view text). Charles S. Keyser, who advocated for a public park at Lemon Hill, lamented the condition of the grounds in 1856, describing the charred remains of the hothouses, the “decayed” grotto and summerhouses, and goldfish ponds now "loathsome with slime” (view text). In 1861, Sidney George Fisher, who remembered Lemon Hill as “beautifully wooded,” decried the felling of its timber at the hands of speculators (view text).
Philadelphians renewed the push to transform Lemon Hill into a public park. Concerned about the deteriorating condition of the Schuylkill, Frederick Graff, Jr. (1817–1890), Chief Engineer of Philadelphia’s Water Department and the nearby Fairmount Water Works, devised a landscaping plan for Lemon Hill and Sedgeley Park, which John Price Wetherill, chairman of the Watering Committee, presented to the city councils in 1851 [Fig. 7]. The plan laid out a system of winding, forty-foot-wide roads that would create a drive several miles long by which the public could navigate the estate, and also proposed preserving Pratt’s mansion. However, according to Elizabeth Milroy, Graff “made no recommendations for new plantings or for the care of existing trees and shrubs.” Graff’s plan was never implemented, but in September 1855, Philadelphia’s Committee on City Property passed a resolution to integrate the Lemon Hill estate into a new public park that was to be named Fairmount Park.
In 1859 the city selected a design for the new Fairmount Park by James C. Sidney (1819–1881) and Andrew Adams (ca. 1800–1860), which encompassed 110 acres extending from the Fairmount Water Works at the south to just north of the Spring Garden Water Works and from the Schuylkill River at the west and the Reading Railroad at the east [Fig. 8]. Like Graff’s earlier plan, the Sidney & Adams plan also called for a system of circuitous drives and walks throughout the grounds of the Lemon Hill estate and the restoration of Pratt’s house. Sidney and Adams recommended the creation of a sixteen-foot-wide piazza that would surround Pratt’s mansion on three sides and the restoration of terraces to the east of the house that would be planted with beds of roses and flowering shrubs. Their plan also proposed the creation of a grand tree-lined avenue of American Lindens; the planting of various flowering, deciduous, and evergreen trees; and the construction of “summer houses, kiosks, rustic seats, fountains, ornamental bridges, boat houses, fish ponds &c.” In the view of a writer for The Gardener’s Monthly, such improvements would help return the grounds to some “vestige of its former splendor,” when, under Pratt’s ownership, Lemon Hill had been considered one of the finest gardens in America. Although the execution of the Sidney & Adams plan for Fairmount Park was often delayed during the Civil War, as Michael J. Lewis has argued, the city moved decisively and, by 1866, “Sidney’s plan was in large measure realized,” with “its apparatus of drives and paths, its planting scheme, and landscaping” completed and available for public use.

- Anonymous, 1821, describing an exhibition of an aloe plant from Lemon Hill (The Plough Boy: 30)  back up to history
- [June 6] "It is believed that, but two of those plants have come to perfection in the United States. One was at Springbury, the seat of William Penn, near Bush Hill. This plant flowered in 1777. From it the late Mr. William Hamilton got a sucker, which he was fortunate enough to rear, and it flowered at the Woodlands, in the year 1804. When Henry Pratt, Esq. bought Lemon Hill, from the late Robert Morris, there was an Aloe in the Green House. This plant has been cherished and tended for 70 years, with great care, and is now RAPIDLY advancing to an exhibition of all the fragrance and beauty, of which it is susceptible. We will here, perhaps a little out of place, embrace the occasion, to pay homage of our consideration and thankfulness to Mr. Pratt, for the distinguished liberality with which his gardens, green houses, &c. are, and long have been, thrown open to strangers and to citizens.
- "Mr. Pratt, with a liberality and benevolence which entitle him to great praise, has bestowed his plant on the Orphan Asylum, on Cherry-street, near Schuylkill Sixth-street: where it will be exhibited to the public for the benefit of that charitable institution. A building for the reception of the Aloe, being completed at the Asylum, the plant was yesterday moved thither from Lemon Hill. The greatest care was necessary and was taken in the removal. The Aloe was carried, the whole distance, on the shoulders of 24 men, and we have pleasure in saying that it did not sustain the slightest injury.
- "On the 28th of May last, it was observed that this interesting plant had put forth and unerring evidence that it was about to flower. It put forth an upright shoot, like a strong asparagus. This stem, since that time, has grown 5 feet 8 inches; considerably more than the plant had grown in 60 years before. It will be in full flower about the middle of July next.
- "We give this early notice of this interesting exhibition to afford persons at a distance an opportunity of making their arrangements to enable them to enjoy the gratification of beholding so rare and beautiful a sight.--Democratic Press.
- [June 8] "We have great satisfaction in announcing, that Mr. Henry Pratt, not content with the liberality he had already shewn to the Widow's and Orphan's Asylum, by the generous gift of the FLOWERING ALOE, has made most liberal additions to his bounty. To render the exhibition at the Asylum as interesting and of course as profitable as possible, Mr. Pratt yesterday sent to that institution a considerable number of rare and beautiful tropical plants. Among them were the Night Blooming Ceres, the Rose Apple of the West Indies, the Sago Palm, the Coffee Tree, the Sugar Cane, &c. &c.--Ibid."
- Bernhard, Karl, Duke of Saxe-Weimar, 1825, describing Lemon Hill (1828: 1: 140–41)  back up to history
- "A merchant, Mr. Halbach, to whom I was introduced, took a walk with me to two gardens adjoining the city. One of these belongs to a rich merchant, Mr. Pratt, and is situated upon a rocky peninsula, formed by the Schuylkill, immediately above the water-works. The soil consists mostly of quartz and clay. The owner seldom comes there, and this is easy to be perceived, for instead of handsome grass-plots you see potatoes and turnips planted in the garden. The trees, however, are very handsome, mostly chestnut, and some hickory. I also observed particularly two large and strong tulip trees; the circumference of one was fifteen feet. In the hot-houses was a fine collection of orange trees, and a handsome collection of exotic plants, some of the order Euphorbia from South America; also a few palm trees. The gardener, an Englishman by birth, seemed to be well acquainted with his plants. Through a hydraulic machine the water is brought up from the river into several basins, and thence forced into the hot-houses. There was also in the garden a mineral spring of a ferruginous quality. From several spots in the garden there are fine views of the Schuylkill, whose banks, covered with trees, now in the fall of the year, have a striking and pleasant effect from the various hues of foliage."
- Wailes, Benjamin L.C., December 29, 1829, describing Lemon Hill (quoted in Moore 1954: 359–60)  back up to history
"But the most enchanting prospect is towards the grand pleasure grove & green house of a Mr. Prat[t], a gentleman of fortune, and to this we next proceeded by a circutous rout, passing in view of the fish ponds, bowers, rustic retreats, summer houses, fountains, grotto, &c., &c. The grotto is dug in a bank [and] is of a circular form, the side built up of rock and arched over head, and a number of Shells [?]. A dog of natural size carved out of marble sits just within the entrance, the guardian of the place. A narrow aperture lined with a hedge of arbor vitae leads to it. Next is a round fish pond with a small fountain playing in the pond. An Oval & several oblong fish ponds of larger size follow, & between the two last is an artificial cascade. Several summer houses in rustic style are made by nailing bark on the outside & thaching the roof. There is also a rustic seat built in the branches of a tree, & to which a flight of steps ascend. In one of the summer houses is a Spring with seats around it. The houses are all embelished with marble busts of Venus, Appollo, Diana and a Bacanti. One sits on an Island on the fish pond. All the ponds filled with handsome coloured fish.
- "The grounds are planted with a great variety of shrubbery & evergreens of various kinds of the pine & fir, and the hot house is said to be the largest in the US. It is filled to overflowing with the choicest Exotics: the Chaddock Orange of different kinds & the Lemon loaded with fruit. There are two coffee trees with their berries. Some few shrubs were in flower & others seeded, & I was politely furnished with a few seed of 2 varieties of flowers (Myrtle & an accacia). In front of the hot house, one at each end, is a Lion of marble, well executed, & a dog in front. On the roof is a range of marble busts."
- Committee of the Pennsylvania Horticultural Society, 1830, describing Lemon Hill (quoted in Boyd 1929: 431–33)  back up to history
"This beautiful garden, so creditable to the owner, and even to the city of Philadelphia, is kept in perfect order at great expense. Few strangers omit paying it a visit, a gratification which is afforded to them in the most liberal manner by the proprietor. Nor can any person of taste contemplate the various charms of this highly improved spot, without being in rapture with the loveliness of nature—everywhere around him, so chastely adorned by the hand of man.
"Undoubtedly this is the best kept garden in Pennsylvania, and when associated with the green and hot house department, may be pronounced unrivalled in the Union. The gravel walks, espaliers, plants, shrubs, mounds, and grass plats, are dressed periodically and minutely. . . .
"Along the walks, the flower borders are interspersed with Thunbergias, Eccremocarpus, Chelonias, Mimosas, &c. The Laurustinus, sweet Bay, English Laurel, Rosemary, Chinese privet, Myrtle, Tree Sage and South Sea Tea, stand among them, and bear the winter with a little straw covering. Even the Verbena triphylla, or Aloysia Citriodora, has survived through our cold season in Mr. Pratt’s city garden; seven of these plants are evergreens, and if they become inured to our climate, they will add greatly to our ornamental shrubs.
"The treasures contained in the hot and green houses are numerous. Besides a very fine collection of Orange, Lemon, Lime, Citron, Shaddock, Bergamot, Pomgranate and Fig trees in excellent condition and full of fruit, we notice with admiration the many thousand of exotics to which Mr. Pratt is annually adding. The most conspicuous among these, are the tea tree; the coffee tree——loaded with fruit; the sugar cane; the pepper tree; Banana, Plantain, Guva, Cherimona, Ficus, Mango, the Cacti in great splendour, some 14 feet high, and a gigantic Euphorbia Trigonia—19 years old, and 13 feet high. The green houses are 220 feet long by 16 broad; exhibiting the finest range of glass for the preservation of plants, on this continent.
"Colonel Perkins, near Boston, has it is true, a grapery and peach Espalier, protected by 330 feet of glass, yet as there are neither flues not foreign plants in them, they cannot properly be called green houses, whereas Mr. Pratt's are furnished with the rarest productions of every clime, so that the committee place the conservatory of Lemon Hill at the very head of all similar establishments in this country.
- "There are some pretty bowers, summer houses, grottos and fish ponds in this garden—the latter well stored with gold and silver fish. The mansion house is capacious and modern, and the prospects, on all sides, extremely beautiful. In landscape gardening, water and wood are indispensable for picturesque effect; and here they are found distributed in just proportions with hill and lawn and buildings of architectural beauty, the whole scene is cheerfully animated by the brisk commerce of the river, and constant movement in the busy neighborhood of Fairmount.
"An engine for raising water to the plant houses, is sometimes put in operation. Mr. Pratt placed it here at a cost of three thousand dollars. The vegetable garden is well kept and is of suitable size. For many years the chief gardener was assisted by eleven or twelve labourers, he now employs only six; probably owing to the finished condition to which the proprietor has brought his grounds. The whole plot may contain about 20 acres; Mr. Pratt has owned it 30 years or more. The superintendent aided by the liberal spirit of that gentleman, conducts his business with skill and neatness, and may challenge any garden for minute excellence or general effect."
- D. & C. Landreth, 1832, describing Lemon Hill (The Floral Magazine and Botanical Repository: 6)
- "The vignette on the title-page, affords an excellent view of these far-famed grounds, from the pencil of ALBRIGHT, engraved by LONGACRE. The Garden is situate on the Schuylkill, above Fairmount Water-works, and is one of the oldest private establishments of its nature in Pennsylvania.
- "For years it was the favourite summer residence of our first financier, ROBERT MORRIS, who originally laid out the grounds, and erected a part of the conservatories which there exist.
- "In this fascinating spot, that worthy man and truly patriotic citizen, passed many of his happiest hours; returned from the city, whither his avocations daily called him, it was his custom and greatest pleasure to ramble around the grounds, planning new improvements, or entering with zest into the operations which were going on. The mutability of all earthly possessions transferred the premises, with the collection, about thirty years ago, to Mr. HENRY PRATT, the present proprietor, who is deserving of much applause for the improvements he is constantly creating. These magnificent grounds are, perhaps, as much favoured by nature, and more by art, than any in the Union; on the southern extremity, they are bounded by the Schuylkill, one of the most picturesque of rivers, enlivened by innumerable craft, laden with mineral and agricultural wealth: at a short distance is beheld the celebrated Water-works, and on a little further, is the 'Upper Ferry Bridge,' that with a single span of 334 feet clasps either shore; still further, the eye rests on a second bridge, with shipping and commercial bustle.
- "The annual expenditure is very considerable. For many years, ten or a dozen labourers under the direction of a gardener, found ample work. The conservatories present an uninterrupted range of 220 feet, and are greater than any others in this country,—indeed would suffer little if compared with many of the trans-atlantic world. An engine for raising water to them, was erected by the present owner, at $3000 cost.
- "In this fairy place, may be seen in a state of perfection, rivalling that of the climes from whence they came, the useful Sugar-cane, the Guava, Mango, and Banana: the exhilarating Tea of India, and Coffee of Arabia; and the Annona Cherimolia, the delicacy of whose fruit, travellers in South America dwell on with rapture. Thousands of exotics decorate the grounds in summer, or crowd the Hot and Green Houses in winter, filling the air with foods of delightful perfume, whilst Oranges, Lemons, Limes, Shaddocks, and other tropical productions, are here in vast profusion.
- "Fountains and fish-ponds, with gold and silver fish, added to the beauty of the scene. Grottos, bowers, and rustic cots, are blended with natural beauties,—all combined, producing an influence no less enchanting than the 'Leasowes.' And surely SHENSTONE had not been the less eloquent, had his poetic genius been cultivated at Lemon Hill.
- "Few strangers visit Philadelphia without an examination of these grounds, and the proprietor has received the thanks of thousands for the gratification his liberality afforded." [Fig. 10]
- A.W., August 1835, describing Lemon Hill (quoted in The New-York Farmer and American Gardener's Magazine 1835: 332)
- "...I steered my course to Lemon Hill, which is the name very appropriately given to the pleasure grounds of Mr. Henry Pratt. It is situated in the immediate vicinity of the grand Water-works, and is said to contain over twenty acres. Nature seems to have displayed her utmost power in modeling this charming situation, leaving but little for art to accomplish, to render it one of the most delightful spots on earth; and art, with such a bold and lovely model, appears to have availed herself of every advantage, to beautify and complete what Nature had so happily begun.
- "The mansion is placed on an eminence, commanding a delightful view of the Schuylkill, just at that point where every thing is in pleasant motion. The busy neighborhood of Fairmount, the interesting views of this fine landscape, are fully kept before the eye, by gently winding paths, through a rich and well kept grass plot; every turn producing some new and pleasing effect. The foot does not tread in the same path which the eye has gone over before. The groups of lofty trees, so advantageously placed on the hill, near the house, with their deep green foliage, form a beautiful contrast with those of more light and stinted growth, situated in front of the ground bordering on the water; thereby adding much to the effect, by seeming to remove the perspective to the farthest extremity of the picture. The numerous well stocked fishponds, with their islands and aquatic productions, summer-houses, gardens, porters' and laborers' lodges, all well placed for picturesque effect; and the beautiful little grotto, thrown so chastely over the mineral spring, all conspire to complete the beauty and variety, without, in the least marring the productions of nature, so very interesting in the immediate vicinity. The spacious green hot houses with their numerous and lovely tenants, spread far and wide in every direction, making the whole garden a repository of flowers and fragrance, certainly stand prominent in their kind; and as we migrate along the well kept gravel walks, so richly adorned by tree, shrub, and plant, of every shade and shape, and from every climate, intermixed with the inmates of the green house, the shaddock, orange, citron, lime, the fig tree, laden with inviting fruit; the sugar cane, pepper tree, banana, guava, and plantain; the cheremalia, mango, and splendid cactus; a reflecting mind must be lost in admiration, not knowing which most to admire, the amazing variety produced by nature, or the wealth, liberality, and taste, which have planted and sustain them there."
- Downing, A. J., January 1837, "Notices on the State and Progress of Horticulture in the United States," describing Lemon Hill (January 1837: 4)
- "For a long time the grounds of Mr. Pratt, at Lemon Hill, near Philadelphia, have been considered the show-garden of that city: and the proprietor, with a praiseworthy spirit, opening his long-shaded walks, cool grottoes, jets d’eau, and the superb range of hot-houses, to the inspection of the citizens, contributed in a wonderful degree to improve the taste of the inhabitants, and to inspire them with a desire to possess the more beautiful and delicate productions of nature."
- "Lemon Hill, half a mile above the Fairmount water-works of Philadelphia, was, 20 years ago, the most perfect specimen of the geometric mode in America, and since its destruction by the extension of the city, a few years since, there is nothing comparable with it, in that style, among us. All the symmetry, uniformity, and high art of the old school, were displayed here in artificial plantations, formal gardens with trellises, grottoes, spring-houses, temples, statues, and vases, with numerous ponds of water, jets-d'eau, and other water-works, parterres and an extensive range of hothouses. The effect of this garden was brilliant and striking; its position, on the lovely banks of the Schuylkill, admirable; and its liberal proprietor, Mr. Pratt, by opening it freely to the public, greatly increased the popular taste in the neighborhood of that city."
- "850. Lemon Hill, near Philadelphia. . . . [Downing observes:] '. . . An extensive range of hothouses, curious grottoes and spring-houses, as well as every other gardenesque structure, gave variety and interest to this celebrated spot, which we regret the rapidly extending trees, and the mania for improvement there, as in some of our other cities, have now nearly destroyed and obliterated.' (Downing's Landscape Gardening adapted to North America.)"
- Keyser, Charles S., 1856, describing Lemon Hill (quoted in Keyser, et al. 1886: 6–7, 18)  back up to history
- "...by neglect, by fire and by wanton destruction, this place, the abode of a once princely luxury had fallen into ruin; where beautiful hot-houses filled with rare exotics overlooked the river, only falling walls blackened by fire remained; the shrubbery had been destroyed; the little bark grotto over the spring and the shady summer houses had decayed; and the ponds once filled with the gold fish had become loathsome with slime; only the grand old tulip trees remained, and the pines which stood as they still stand to-day, silent sentinels around the deserted mansion. . . .
- "The grounds lie in undulating slopes, breaking off in bluffs at the water’s edge, at heights of perhaps from 50 to 100 feet. The intervening hollows are filled below and near the water’s edge, with an undergrowth of shrubbery. They spread out in an easy ascent to the slopes above, covered with greensward. Upon the highest point of the grounds midway between the two Water Works, are the remains of the foundation of a small building, perhaps a summer house; it is surrounded with a broken circle of cedar trees. Further down towards the dam, on a beautiful lawn overlooking Fairmount, stands the mansion house; near this are the ruins of the summer houses. Back towards the railroad from the mansion, down a thickly wooded descent, is the once beautiful spring. A carriage drive appears from the position of some trees, yet remaining in a traceable order, to have followed the course of the river along the summit of the slopes through the grounds. Some large tulip trees of beautiful form and some venerable pines remain."
