Garden to Table - Jefferson's (1743-1824) Slave Cook Frances (Fanny) Hern

Monticello's kitchen, restored to its 1809 configuration

 Frances (Fanny) Gillette Hern, An Enslaved Cook

From Monticello's Digital Classroom

Frances (Fanny) Hern was the daughter of Edward and Jane Gillette, enslaved farm laborers who had twelve children. While Thomas Jefferson was president, the family worked in the fields for a tenant on the Monticello plantation.

Fanny married David (Davy) Hern, who worked at Monticello as an enslaved nailmaker, blacksmith, and wagon driver. In 1806, Thomas Jefferson decided that Fanny and Edith Hern Fossett, Davy’s sister, should go to the White House and train to be cooks. They traveled the 120 mile journey in a cart pulled by two mules.

At the White House, Fanny trained with chef Honoré Julien. She received a small gratuity but not a wage. Her husband visited every six months, arriving at the White House with letters and crates of supplies, departing for Monticello with seeds, trees, geese, and hogs. While at the White House, Fanny and Davy’s daughter died of whooping cough.

In 1809, Jefferson retired from the presidency and left the White House. Fanny, Davy, Edith, and Edith’s children traveled back to Monticello through a snow storm “half-leg deep.” Fanny was pregnant. That summer, her daughter Ellen was born. Fanny and Davy had eight children; however, five died at a young age

Fanny continued to work as a cook in the Monticello kitchen, located under the south terrace. She and Edith, the head chef, cooked on “iron stew holes mounted in a brick base”, which resembled an early kitchen stove. They prepared vegetables, roasted meat and churned ice cream, a favorite dessert at Monticello. Jefferson’s guest praised the meals: “The dinner is always choice and served in the French style.”

Metal & Clay Cloches

I have been taken to task by one of my garden history colleagues for being politically incorrect in my biased presentation of glass cloches. He is correct, of course. The only fair thing to do here is show you the other types of cloches from the 17th, 18th, & 19th centuries, some still in use today. They do deserve equal time.

Handmade terra-cotta cloches have existed nearly as long as the blown-glass examples. They often have ventilation holes to prevent spoilage from excessive heat & humidity.

Gardeners often used terra-cotta cloches slow the growth of lettuce.

Other terra-cotta cloches, often about 30" high & similar in shape to chimney pots, were used for forcing rhubarb. Some of these had lids.

Gardeners also used metal-framed glass cloches during the period.


In metal-framed cloches, one of the glass panes could be removed by the gardener for fresh air ventilation. Sometimes gardeners temporarily would paint the glass white to shade tender plants from direct sunlight.

Today, these architectural tents or pavilions are more often employed for decorative purposes.

I found only one depiction of a completely metal cloche made in France about 1900.

Let me close by admitting what you surely already realize, I just love those plain, bell-shaped glass cloches...

Very clever make-do cloches.  Lined basket food covers.

Tho Jefferson (1743-1824) Writes about Gardening

 

Thomas Jefferson by Tadeusz Andrzej Bonawentura Kosciuszko (1746 - 1817) 

1800 January 27.  (Jefferson to Joseph Priestley).  "to all this I add that to read the Latin & Greek authors in their original is a sublime luxury; and I deem luxury in science to be at least as justifiable as in architecture, painting, gardening or the other arts."

Joseph Priestley ( 1733 –1804) was an English chemist, natural philosopher, separatist theologian, grammarian, multi-subject educator, & liberal political theorist who published over 150 works. The controversial nature of Priestley's publications, combined with his outspoken support of the French Revolution, aroused public & governmental suspicion; he was eventually forced to flee in 1791, first to London & then to the United States, after a mob burned down his Birmingham home & church. He spent his last ten years in Northumberland County, Pennsylvania.

Garden Design -Terraced or Falling Gardens

As the 18th century progressed, American colonists were growing richer & found themselves with enough free time to think about designing the grounds around themselves to project their new wealth & power. The gentry began to employ professional gardeners who often planned for land on one side of their employer's house to become a falling garden.

Many well-to-do homeowners intentionally chose their home sites on naturally sloping ground or on the bank of a river. They intended to plant level grassy (or more intricate) garden areas as part of a series of terraced falls or graduations with sloping turf fronts & sides. Often when the dwelling house was newly built, the earth, clay, & rubbish removed for cellars & foundations were used to shape the terraced falls. Hills were intentionally cut into slopes & flats where owners & guests could walk.

Visitors traveling on land would usually approach the formal entrance to a house by a flat carriage way. Guests asked to stay for a while, often would be invited to take a walk in the terraced garden on the opposite side of the home. People usually walked between these flat levels by means of grass ramps.

Each individual descent was referred to as a fall. Gentry owners showcased their genteel taste in gardening on these terraces, which served as their stage to those passing by or visiting.

Historically from Persia to Italy to England, terraces have provided a setting for the house, a pleasing view from upper story windows, a platform for surveying the surrounding countryside, and a grand stage for the owner. A contemporary American garden authority acknowledged the garden as a stage when he wrote, "regular terraces either on natural eminences or forced ground were often introduced...for the sake of prospect...one above another, on the side of some considerable rising ground in theatrical arrangement."

Such designs elevated the wealthy owner above the common audience passing by or strolling through. One look at nature so well ordered, and the observer could have no doubt that here lived a person destined to be in charge.

Falls appeared early in colonial Virginia, where Lieutenant Governor Alexander Spottswood (1676-1740) installed terraced gardens at the Governor's Palace in Williamsburg between 1715 & 1719. The legislature had authorized moneis for the palace and for its formal walled gardens in 1706.

When new Virginia Governor William Gooch (1681-1751) arrived in 1727, he wrote of a "handsome garden, an orchard full of fruit, and a very large park." The walled entrance courtyard was separated from the rear formal garden by brick walls. A gate to the east of the formal garden led to Lieutenant Governor Alexander Spotswood's (1676-1740) "falling garden," a seried of three terraces descending to a ravine where Spotswood had a stream dammed to create a "fine canal."

Later Spotswood built a private estate near Germanna, where William Byrd II came to call in 1732, & reported, "the Garden...has...3 Terrace Walks that fall in Slopes, one below another."
Berkeley on the James River in Virginia

Spotswood's falling garden at the Governor's Palace spawned a slew of Virginia imitators. In 1726, Benjamin Harrison IV and his wife Anne Carter built Berkeley on the James River. The house faces the river on top of a hill with 3 grand, descending terraces dropping to the river and Harrison's Landing.
Carter's Grove on the James River in Virginia

In the 1730s, Virginian Lewis Burwell constructed a rectangular garden, 200' wide with 3 terraces dropping 500' down to the James River at his plantation Kingsmill. In 1751, his cousin Carter Burwell borrowed that design for his Carter's Grove which still can be visited near Williamsburg.

19th-century Depiction of the terraced gardens at Carter's Grove

During the same decade, John Robinson, Speaker of the Virginia House of Burgesses, installed "a large falling garden enclosed with a good brick wall" at his home Pleasant Hall overlooking the Mattaponi River.

Some garden terraces proved treacherous. In the 1730s, Landon Carter built a falls garden at his home Sabine Hall on the north side of Virginia's Rappahannock River. Carter's garden consisted of 6 deep falls spanning the width of the house & dropping to the river below. The terraces were so steep, that he "almost...disjointed" his hip by "walking in the garden." In 1783, the elder Charles Carroll of Annapolis actually died as a result of a fall in his garden.

The same style garden also was appearing in more conservative New England as well. In 1736, Will Griff's contract to build Thomas Hancock's house & garden in Boston stated, "I...oblidge myself...to...layout the next garden or flatt from the Terras below." He also agreed to "order and Gravel the Walks & prepare and Sodd ye Terras adjoining with the Slope on the side."

Parnassas Hill home of Dr. Henry Stevenson painted by Charles Willson Peale (1741-1827) about 1769.

In Maryland, Irishman Dr. Henry Stevenson (1721-1814) built his home Parnassus Hill between 1763 & 1769, on the Jones Falls River north of Baltimore, where he & his brother, also a physician, actually made their money as wheat exporters. Dr. Henry Stephenson, who had come to Maryland in 1745, also pursured medicine pioneering a smallpox vaccine.  In February of 1769, the Maryland Gazette noted, "Dr. Henry Stevenson devotes part of his mansion on 'Parnassus Hill' to the use of an Inoculating Hospital, and opens it to all who may apply." The hospital closed in 1777, as staunch loyalist Stevenson left Baltimore to serve in the British service as a surgeon in New York, returning to Baltimore in 1786, when Revolutionary tempers had cooled. The terraced gardens at the combination home & hospital were among the earliest in Baltimore.

William Paca (1740-1799), a signer of the Declaration of Indpendence & a federal district court judge, was born in Harford County, Maryland, and educated in Philadelphia and London. In 1763, Paca ensured his social & economic position by marrying Mary Chew, the daughter of a wealthy Maryland family.

Four days after their wedding, Paca purchased two lots in Annapolis and began building the five-part mansion plus an extensive pleasure garden.  Paca planned a walled garden for his new home in the 1760s.

Constructed between 1763-1765, the estate is known chiefly for its elegant falling gardens including 5 terraces, a fish-shaped pond, and a wilderness garden.

The garden was to consist of 3 falls, narrowing as they dropped 16 1/2' to the lowest level of the garden. The terrace closest to the house measured 80' in width, the next 55', & the last 40'. This design allowed those viewing the 2 acre garden from the house to see grounds that appeared larger than reality, & those viewing from below to see a house that seemed grander than it was.

Using "optics" to create an illusion of larger houses & grounds was particularly important in colonial towns, where space was limited, but the need to appear important was boundless.

Another terraced garden in Marylnad belonged to Charles Carroll, the Barrister, 1723-1783, who had spent his youth in England receiving a classical education. He did not marry the 21 year old Margaret Tilghman 1743-1817, until he was 40 in 1763. By then, he was working on completing the house and grounds at his country seat near Baltimore.  In 1756, Carroll had begun construction of his country house Mount Clare. A series of grass ramps led from the bowling green down shaded terraces or falls. A sweeping view spread across the lower fields to the waters of the Patapsco River, about one mile away.

The gardens were popular with visitors. In 1770, Virginian Mary Ambler visited and recorded that she, "took a great deal of Pleasure in looking at the bowling Green & also at the...Very large Falling Garden there...the House...stands upon a very High Hill & has a fine view of Petapsico River You step out of the Door into the Bowlg Green from which the Garden Falls & when you stand on the Top of it there is such a Uniformity of Each side as the whole Plantn seems to be laid out like a Garden there is also a Handsome Court Yard on the other side of the House."

When John Adams, in Baltimore for a session of the Continental Congress in February of 1777, spoke highly of Mount Clare. "There is a most beautiful walk from the house down to the water; there is a descent not far from the house; you have a fine garden then you descend a few steps and have another fine garden; you go down a few more and have another."

Because the land around the harbor at Baltimore was hilly as it dropped toward the bay, many builders chose terraced falling gardens for the south side of their homes. The terracing of gardens itself served both aesthetic & practical purposes in the colonial Mid-Atlantic.  Pragmatic Mid-Atlantic landowners often constructed their terraces when the dwelling house was newly built; so that the earth, clay, and rubbish that come out of the cellars & foundations could be used to shape the falls.

On the same 1777 visit to Baltimore, John Adams noted in his diary, William Lux's Chatsworth, The seat is named Chatsworth, and an elegant one it is -- the large garden enclosed in lime and before the yard two fine rows of large cherry trees which lead out to the public road. There is a fine prospect about it. Mr. Lux lives like a prince. The grounds included an enclosed 164 ' by 234' terraced garden which fell toward the Baltimore harbor.

On uneven hillsides, terraces created flat areas for planting & helped control erosion. In 1772, Charles Carroll of Annapolis (1702-1782) wrote to his son, Charles Carroll of Carrollton, who was improving his gardens which dropped to the bank of Spa Creek, “If you wish to make a continental slope from ye Gate to ye wash house, I apprehend the Quantity of Water in great Rains going ye way may prove convenient.”  The elder Carroll was still fretting about those garden slopes in 1775, as he wrote his son again: “Examine the Gardiner strictly as to...Whether he is an expert at leveling, making grass plots & Bowling Greens, Slopes, & turfing them well.” Carroll was well aware that falls were functional devices which could divert water drainage & reduce soil erosion.

The Carroll family gardens in Annapolis covered about 2 3/4 acres. The Carrolls were the weathiest family in Maryland with hundreds of acres across the state, but their in-town space was limited. Broadening terraces fell 24' from the house to Spa Creek in Annapolis. The garden terrace closest to the water was 50' wide, the next ascending terrace 40' wide, & the terrace closest to the house measured 30' in width. This plan made the 3 story house seem even more imposing when viewed by visitors approaching from the water.  The Carrolls planted the beds of the terraced gardens at their home in the capitol of Maryland with an eye toward practicality. Orderly squares filled with vegetables surrounded by low privet hedges decorated the flats of Carroll’s falls garden. Painter Charles Wilson Peale reported, "the Garden contains a variety of excellent fruit, and the flats are a kitchen garden.”

When New England schoolteacher, Philip Vickers Fithian visited Nomini Hall in Virginia, he recorded in 1773, "From the front yard of the Great House...is a curious Terrace covered finely with Green turf & about five foot high with a slope of eight feet, which appears exceedingly well to persons coming to the front of the house... This Terrace is produced along the Front of the House...before the Front-Doors is a broad flight of steps of the same Height & slope of the Terrace."

Back in New England on 1774, Elihu Ashley reported seeing the house of Massachusettes Loyalist Timothy Ruggles, where the "land descends the the South, and he designs to make three Squares one about four feet above the other, which will make a most agreable Graduation, and if ever finished will be the grandest thing in the Province of its kind." Unfortunately, in 1775, the Rev. Mr. Ruggles left Boston with British Troops heading to Nova Scotia, where he settled permanently. His estates, gardens & all, in Massachusettes were confiscated. When he fled, Ruggles left his daughter, Bathsheba behind in Massachusetts. In 1778, she was hung to death while pregnant for killing her husband Joshua Spooner & stuffing his body down a garden well. Turbulent times.

In the midst of the Revolution that drove Timothy Ruggles away, Virginia military Colonel George Braxton also had his garden on his mind & wrote in a letter home, "I agreed wth Alexander Oliver Gardener...to finish my falling Garden wth a Bolling Green." After the war was over, travelers began to tour the new confederation. Thomas Lee Shippen described Westover on the James River in Virginia in December of 1783, "...commanding a view of a prettily falling grass plat...about 300 by 100 yards in extent."

In July of the same year, Johann David Schoepf visited the garden of father & son botanists John & William & Bartram in Philadelphia, "The Bartram garden is situated on an extremely pleasant slope across the Schuykill."  While the gardens of the Bartram's in Philadelphia did drop toward the water, they were not laid out as traditional falling terraces.

When the Revolution was won & before he became the nation's first President, George Washington retired to Mount Vernon, where he actively planned & maintained his gardens. In February of 1785, Washington noted in his diary, "Planted ...Brown Berries in the west square in the Second plat...next the Fall or slope."

By 1777, terraced falls were so admired along the Rappahannock River in Fredericksburg, Virginia, that 8 lots were offered for sale in the newspaper noting that 4 were already "well improved with a good falling Garden." A 1780 ad in the same paper touted "a good dwelling house with every conveniencey that a family can wish for...a falling garden." House-for-sale advertisements in Maryland also reported terraced gardens.

Of the traditional four-bed gardens near Baltimore, 15 sat on terraced falls. Typical of these was merchant John Salmon’s home, which perched atop a Baltimore County hill adjoining the country seat of his fellow merchant, Robert Oliver (1757-1834). Oliver was an Irishman from Belfast who arrived in Baltimore in 1783, working there as a merchant until 1819. The neighbors’ homes had mirror-image four-bed terraced gardens descending in the direction of the bay. Also arriving in Baltimore in 1783, Salmon built a two-story home with a balcony & piazza facing south, overlooking his falling gardens commanding a view of the town, harbor, & harbor below. In 1794, John Salmon's Baltimore property contained, "The garden ground...is laid off in beautiful falls." And in January, 1802, a notice announced, "Public Auction...estate of...Richard Chew...1220 acres...situate in Anne-Arundel county, lying on the Chesapeake Bay...a large and elegant garden laid off with falls."

A Baltimore country seat probably more remarkable for its name than its falling gardens was . This home was situated on about 260 acres acquired by David Harris (1752-1809), who built the house & gardens between 1791 & 1793. Harris was the cashier of the Office of Discount & Deposit, a leading banking institution in Baltimore, after which he apparently named his estate.

Nearby in Baltimore sat Bolton, which George Grundy built immediately after he acquired the 30-acre property in 1793. Grundy planned his garden at Bolton to consist of 3 individually fenced rectangular turfed falls dropping south toward the harbor. These terraces were more than 3 times the width of the house, & initially the lowest rectangular terrace was planted in rows to serve as a kitchen garden. Gravel walks defined each terraced division, & a walkway ran from the house bisecting each terrace.

At the turn of the century, Grundy altered the lower garden to a semicircular bed surrounded by a white picket fence that projected from the fencing enclosing the rectangular terrace just above it. In the center of this semicircle was a large flowering tree or group of shrubs surrounded by a circular walkway. Outside of this walkway & within the picket fence were rectangular beds now planted with flowers instead of vegetables & herbs.

The large flowering tree or group of shrubs in the middle of the lowest flat at Bolton may have been a living bower or arbor. Colonial Americans had for decades planted trees, shrubs, flowering beans & vines for cooling shade. A visitor reported in 1679, “We had nowhere seen so many vines together as we saw here, which had been planted for the purpose of shading the walks on the river side.” In 1787, at Grey’s Gardens near Philadelphia, Manasseh Cutler reported, “At every end, side, and corner, there were summer-houses, arbors covered with vines or flowers or shady bowers encircled with trees and flowering shrubs.”
Francis Guy (1760-1820). Bolton From the South Garden Facade. 1800 Maryland Historical Society. Baltimore. Detail Vegetable Garden at the bottom of the falling terraces.

It is possible that the unusual large circle of shrubs or trees in the midst of Bolton’s garden may have been similar to the one in Salem, North Carolina, where a visitor wrote, “into the garden…we saw…a curiosity…extremely beautiful. It was a large summer house formed of eight cedar trees planted in a circle, the tops whilst young were chained together in the center forming a cone. The immense branches were all cut, so that there was not a leaf, the outside is beautifully trimmed perfectly even & very thick within, were seats placed around and doors or openings were cut, through the branches, it had been planted 40 years.”

Terraced gardens continued to appear in the 19th century as settlers moved westward along the Ohio River. These terraced gardens from America's colonies & new republic were often reproduced in the late Victorian period throughout the United States.

Home on the Ohio River early 1800s

Colonial revival gardens usually were built with brick or stone stairways rather than grass ramps leading from one level to the next making walking a little safer. And, perhaps, 19th century gentry drank a little less spirits than their ancestors.

Tho Jefferson (1743-1824) Writes about Gardening

 

Thomas Jefferson by Tadeusz Andrzej Bonawentura Kosciuszko (1746 - 1817) 

1791 February 9.  (Jefferson to Martha Jefferson Randolph).  "I hope you are getting well, towards which great care of yourself is necessary: for however adviseable it is for those in health to expose themselves freely, it is not so for the sick. You will be out in time to begin your garden, and that will tempt you to be out a great deal, than which nothing will tend more to give you health and strength."

Martha "Patsy" Jefferson Randolph (1772-1836) was the eldest daughter of Thomas Jefferson, the third President of the United States, & his wife, Martha Wayles Skelton Jefferson. She was born at Monticello, near Charlottesville, Virginia. Her mother died when she was 10 years old, when only two out of her five siblings were alive. By 1804, she was the lone surviving sibling. Martha was very close to her father in his old age. She was the only one of his children, with his wife Martha, to survive past the age of 25. Patsy had a close relationship with her father, who saw that she had a good education. She spoke four languages & was greatly influenced by the education she received, in a Paris convent school, with daughters of the French elite.

Garden Tools - Glass Bell Jars & Cloches

Bell glasses or cloches in this 1779 Pierre Philippe Choffard (Print made by); Jean Michel Moreau le jeune (After)  Emile ou de l'Education, volume III, page 98, of Rousseau's 'Oeuvres complètes' (Brussels Boubers, 1774).

About 1630, blown-glass cloches were first mentioned in gardening treatises. John Evelyn (1620-1706) included bell glasses in his Elysium Britannicum, or The Royal Gardens in Three Books. The classic garden cloche is a bell-shaped glass vessel with an open bottom.   A 2007 excavation in Northamptonshire, England, revealed bell domes providing evidence for the use of garden glassware during the latter stages of post-medieval Roman occupation.  In his 1732 Gardener's Dictionary, Philip Miller wrote of putting bell glasses over cauliflowers.  By this period in the British American colonies, Miller was deemed the authority on gardens & his books were plentiful along the Atlantic coast.  

In the December 23, 1737 Virginia Gazette, an item about a horse dying because it cut its knee by falling on a garden bell glass is the earliest mention I can find of the bell glass in the colonies. 

A 1970 archaeological dig in Williamsburg, Virginia, unearthed 2 knobs & one folded rim fragment from large gardem bell glasses made from the normal bottle glass metal. Fragments of at least 12 such garden glasses were found at one site & were believed to have come from the John Custis site. Custis was an avid gardener. Fragments of similar glasses have been excavated in Williamsburg at the Governor's Palace, Peter Hay's Shop, the Raleigh Tavern, the Wythe House, & John Carter's Store.  

Historical records indicate that bell-glasses were made in Pennsylvania as early as 1767, at Henry William Stiegel’s glasshouse in Manheim.  Called a “glasshouse” by Stiegel, the 1st glass was blown there in late 1764.  Stiegel hired skilled workmen from the European glassmaking centers, who would have been acquainted with making garden bell glasses. Newspaper advertising brought customers from New York, & Boston, as well as from nearby towns in Pennsylvania.

By 1775, the Philadelphia Glass Works of Kensington advertised bell glasses, along with other wares, in the Pennsylvania Packet.   

On April 16, 1796, bell glasses were for sale from the Albany Glass Factory according to the Herald newspaper in the city of New York. The glassworks was founded by Leonard de Neufville, who recruited experienced glass workers from Germany.
Using an incubating cloche in the early spring or late fall garden is an ideal way to protect infant seedlings. When unpredictable spring weather offers up a cold snap or chance of frost, the vigilant cloche acts as a miniature greenhouse.
Cloches hold in heat & moisture and offer shelter during bursts of strong spring winds.  Using a cloche, when delicate plants are their most vulnerable, is a totally organic way to protect them from deer, birds, slugs, & other pests, which abound up here in our woods.
One problem with the glass bell is that on particularly sunny days, that covered young plants might scorch in the hot sun.
Beningborough Hall, North Yorkshire, England

During high humidity, the gardener should also be on the lookout for mildew. When it’s particularly hot or moist, the gardener can temporarily remove the cloche or prop it up with a stick or small rock to let a bit of heat out & to allow the air to circulate.
In spring, delicate young seedlings can be planted out weeks earlier than would otherwise be feasible under the protection of a prudent cloche. Using a cloche will also extend the season for crops in the autumn by up to 3 weeks.
Beningbrough Hall & Gardens, Beningbrough, York, North Yorkshire, England

The curved shape allows the surface of the cloche to always be perpendicular to the direction of the sun thereby achieving minimum refraction & maximum penetration of light. A very simple but efficient tool.
Colonial Williamsburg in Virginia

The obvious limitation of a bell cloche is its capacity. A cloche is usually capable of covering only a single plant or a tiny collection of small seedlings. For gardening on a larger scale the cloche becomes somewhat impractical, but it always remains beautiful.

A number of garden bell glasses or cloches appear in this print for of the London & Greenwich Railway, 1835.
