An Unpopular Case
Learn how the Harrison vs. Lee trial established Thomas Stone as one of the major trial lawyers in Maryland. Despite suffering defeat in the unpopular case, Stone's skill as a lawyer led Maryland to select him to represent the colony in the Continental Congress and ultimately led him to become one of 56 signers of the Declaration of Independence in 1776.

William Stone Arrives in the New World
William Stone came to Virginia from England in 1628. He was appointed as governor of Maryland in 1648 due to his Protestantism. Stone served during a time of religious conflict in the colony, leading to his removal from office, defeat in battle and imprisonment. Upon his release, Stone was awarded property in Charles County, where he built Poynton Manor. Stone's descendants included a Maryland governor, a U.S. Congressman, and a signer of the Declaration of Independence.

From Potapaco to Port Tobacco
While exploring the area around modern Charles County, Captain John Smith encountered an Native American village, which he listed as “Potopaco.” The natural resources, the strategic position, and farming potential, led Europeans including Catholics, Anglicans, and Puritans to settle in the area. The mixture of Native American and European, as well as the different religious and cultural value systems led to tensions and conflict that raged for more than a century.

The Mob and the Peggy Stewart
Growing tensions between the colony of Maryland and Britain over British treatment of the American colonists, turned violent in October, 1774 with the burning of the Peggy Stewart, a ship carrying tea and other items that Maryland's officials banned from the colony. The burning of the Peggy Stewart and its cargo of tea was one of a series of colonial actions against the British government. Within six months of the destruction of the Peggy Stewart, warfare began.

The March of Maryland’s Macaroni
Early in the Revolutionary War, the British taunted the Americans by singing a version of the song, "Yankee Doodle" with the lyrics of “Stuck a feather in his cap And called it macaroni.” The British suggested that the Americans were fools (or doodles) to think that the addition of feathers to the attire of unsophisticated Americans made them special. Learn what a "macaroni" was, and how Americans took an insulting song and made it their own.

John Hoskins Stone and the Revolutionary War
While forgotten by most people today, John Hoskins Stone is one of Maryland's great Founding Fathers. Stone helped establish the famed First Maryland Regiment, which turned the tide in many battles in the Revolutionary War.

Resilient Forests Initiative - Managing Deer Impacts
A healthy forest needs to have enough tree seedlings and saplings to regenerate the forest canopy after a disturbance. Analysis of NPS I&M and other long-term datasets makes it clear that many eastern national parks lack adequate tree regeneration due to decades of over browsing by white-tailed deer.

I&M Networks Support Resilient Forest Management
NPS Inventory and Monitoring Networks have been tracking forest health in eastern national parks since 2006. This monitoring information can guide resilient forest management and support parks in adapting to changing conditions through the actions described below.

Managing Resilient Forests. A Regional Initiative
Forests cover tens of thousands of acres in eastern national parks and these critical resources face a range of interacting stressors: over-abundant white-tailed deer populations, invasive plant dominance, novel pests and pathogens, among other threats. The Resilient Forests Initiative will help parks address these issue collectively.

Series: Managing Resilient Forests Initiative for Eastern National Parks
Forests in the northeastern U.S. are in peril. Over-abundant deer, invasive plants, and insect pests are negatively impacting park forests, threatening to degrade the scenic vistas and forested landscapes that parks are renowned for. With regional collaboration, parks can manage these impacts and help forests be resilient. This article series explores tools available to park managers to achieve their goals.
Healthy forests have many native seedlings and saplings.
Resilient Forests Initiative - Managing Invasive Plants & Pests
Park forests are threatened by invasive plants and pests. Strategically tackling invasive plants to protect park’s highest priority natural resources and planning around forest pests and pathogens are important actions in managing resilient forests.

Updated Species Database Will Help Boost Amphibian Conservation Across the National Park System
To steward amphibians effectively, managers need basic information about which species live in parks. But species lists need constant maintenance to remain accurate. Due to recent efforts, the National Park Service now has an up-to-date amphibian species checklist for almost 300 parks. This information can serve as the basis for innumerable conservation efforts across the nation.

Project Profile: Managing Resilient Eastern Forests
The National Park Service will improve the ecological health of eastern forests in 38 parks using an array of management techniques. The NPS has selected forest ecosystems of high ecological and cultural value across multiple parks from Virginia to Maine that are at greatest risk of forest loss due to chronic and interacting stressors.

Inventory & Monitoring Partnerships Aim to Improve Park Forest Health from Coast to Coast
From coast to coast, the NPS Inventory and Monitoring Division is helping park managers improve the health and function of forest ecosystems. From promoting resilient forests in the Northeast, to conserving whitebark pine in the West, to protecting Hawaiian forest birds from avian malaria, scientific partnerships are helping parks to share information, leverage funding sources, and work together for outcomes that extend beyond what any park could accomplish on its own.

T
homas Stone started building
his home Haberdeventure in the
1770s as a place to raise his family. A modest family man then, Stone
showed promise as a lawyer and local
political figure. But soon Stone stepped
onto a far larger stage. In 1776 Thomas
Stone signed the Declaration of Independence—and wrote himself into history. Stone spent the rest of his life in

mounted. The next year the Maryland
Convention chose him for the Second
Continental Congress. When it met on
May 10,1775, the colonies were effectively at war. By 1776 Maryland stood
for independence from Great Britain.
Had colonists not won the Revolutionary War, Thomas Stone could have
been hunted down and hanged as a
traitor to the British crown. And Stone,
deliberative by nature, did not take
lightly his change of heart: from loyal
subject to American revolutionary.
Independence, much less nationhood,
was a fragile hope in 1776. What Stone
signed was "The unanimous Declaration of the thirteen united States of
America." The u in united was not capitalized. Nationhood—a United States
of America—still lay in the future.
Believing in peace, Stone had nevertheless come to see the colonies' escalating
conflict with the British as the issue
of freedom. But there was no script to
follow. This was purely improvisation.

Thomas Stone was born at Poynton
<
Manor, near Port Tobacco, in Charles
County, Maryland, in 1743. Little is
known of his youth, but his education,
as befit affluent young men of his day,
emphasized Greek and Latin languages
and philosophy. This early training later
influenced his study of law. By 1765
Stone was practicing law as a circuit
rider between Port Tobacco, Frederick,
and Annapolis.
" . . . we mutually pledge to each other
our Lives, our Fortunes and our sacred
Honor!' As you look at Haberdeventure
today, try to imagine Thomas Stone and
his wife Margaret agonizing over putting everything they owned on the line
—their home, the plantation, the slaves,
and even Thomas's neck—against such
a fragile hope of freedom for America.
Stone was known to weigh all options
in making decisions—a trait he carried
into politics. At age 31 he was chosen as
a member of the Charles County Committee of Correspondence, charged
with keeping in touch with the other
colonies, as tensions with Great Britain
. . . my heart wishes for peace...

Visiting the Stone Plantation
Haberdeventure supported 25 to 35 people, including slaves and
Thomas Stone's extended family. He enlarged the original 442-acre
plantation to 1,077 acres. Wings are connected to the central block
of the house by structures called hyphens, in an unusual arc resulting in a five-part colonial house. Fire destroyed the center block in
1977, and the home has been restored to its earliest known configuration, as seen in a 1902 photograph. The house was opened
to the public in 1997.

Stone family, this large Chinese export
porcelain bowl was in the Stones' home
in Annapolis, Md., where the family lived
when Thomas died in 1787. Stone's signet

18th-century Plantation Life
Thomas Stone bought Haberdeventure as
a country home more than for agricultural
purposes. Cultivated since the 1680s, the
depleted soil could not produce tobacco,
the cash crop then. Stone grew grains and
livestock and had gardens and orchards,
mostly for the plantation residents, not for
market. That was typical in the 1700s.
Livestock included chickens, cattle, oxen,
sheep, and hogs. Flax and cotton were
grown for making cloth. Old photos show
apple, peach, cherry, pear, and plum trees,
but we don't know when they were planted. (Outdoor photos were not common
until the late 1800s.) Thomas Stone moved
his wife and family to Annapolis in 1783,
leaving a brother to manage the plantation. After Stone died in 1787 it passed
down through five generations of Stones
until it was sold in 1936.
