John Beale Bordley
West Bradford Township, Chester County, Pennsylvania
Marker Inscription
The noted agriculturalist purchased land just north of here in 1792 and named it "Como Farm." Here, he conducted numerous experiments on crop rotation and maintenance of soil fertility. Bordley planned new devices for seeding and reaping wheat. His works on Rotation of Crops and Husbandry and Rural Affairs were widely read. Died, 1804.

The Story
John Beale Bordley bought land here in 1792 and named it Como Farm, turning it into a laboratory for the new scientific agriculture. He tested crop rotation and methods of keeping soil fertile, sketched improved machines for sowing and reaping wheat, and published widely read works on rotation and husbandry. He died in 1804, having helped push American farming from tradition toward experiment.
Why it matters
Bordley was among the gentleman-scientists who founded American agricultural reform, seeding the improvements in soil and yield that would sustain a fast-growing nation.
The story behind this marker
AI contextThe era
In the decades right after the American Revolution, the new republic was overwhelmingly a nation of farmers — and much of its farming was wearing out the land. Generations of planting the same crops in the same fields had exhausted the soil across the older settled regions, and many landowners simply moved west in search of fresh ground rather than repair what they had.
Southeastern Pennsylvania, with its deep limestone soils and prosperous farms, was one of the places where a different idea took root. Here, educated landowners began treating agriculture not as inherited routine but as something to be studied, measured, and improved.
When this land just north of West Bradford was taken up in 1792 and christened "Como Farm," it became part of that quiet revolution. The Early Republic was an age that prized reason and experiment, and a working farm could be a laboratory as surely as any lecture hall.
People & events
John Beale Bordley belonged to a small circle of gentleman-farmers who believed the young country's future depended on rebuilding the fertility of its fields. On the acres he named Como Farm, he put that belief to the test.
He ran experiments in crop rotation — the practice of alternating what is grown in a field from year to year so the soil is not endlessly drained by a single demanding crop. He studied how to keep ground fertile rather than mine it to exhaustion, and he turned his attention to the machinery of the farm as well, sketching improved devices for sowing and reaping wheat.
Bordley did not keep his findings to himself. His writings on the rotation of crops and on husbandry and rural affairs circulated widely among landowners hungry for better methods. He died in 1804, having spent his last years making the case that careful management could renew American soil rather than simply use it up.
Its place in the American story
Bordley was part of the first generation of American agricultural reformers — the gentleman-scientists who insisted that farming could be improved by observation and shared knowledge rather than left to habit. Their experiments and pamphlets laid the groundwork for the agricultural societies and improved practices that spread across the country in the century that followed.
That mattered enormously for a nation about to grow at astonishing speed. A country that could keep its existing farmland productive — instead of exhausting one region and abandoning it for the next — could feed a booming population and build lasting communities.
So a single Chester County farm connects to one of the largest stories in American life: the slow shift from farming as tradition to farming as science, and the quiet ingenuity that helped feed a rising nation.
If you visit
This is a landmark to read rather than to tour — there is no grand building here, just the Pennsylvania countryside and a marker recalling what happened on the land nearby.
Stand for a moment and take in the rolling farm country of Chester County. Much of what you see still owes its productivity to the kind of thinking Bordley championed: rotating crops, replenishing the soil, and treating a farm as something to be improved with care.
It makes a rewarding stop on a drive through Pennsylvania's historic farmland. Pair it with a wander through the surrounding townships, and you can imagine an 18th-century experimenter walking these fields, notebook in hand, trying to coax more life out of the ground beneath your feet.

Joseph T. Rothrock
West Chester, PA · est. 1952
Joseph Trimble Rothrock lived in this West Chester house from 1876 until his death in 1922, during the decades when Pennsylvania's forests were being stripped bare by logging and fire. A physician turned botanist and reformer, he championed the idea that the state should own and manage forests as a public trust, and he became Pennsylvania's first forestry commissioner. His campaigns for fire control, reforestation, and scientific management laid the groundwork for the state forest system.
William Darlington
West Chester, PA · est. 1952
William Darlington began his 33-year tenure as president of the Bank of Chester County in this building in 1830, capping a life that ranged across medicine, politics, and science. A physician and former congressman, he is best remembered as one of early America's most respected botanists, cataloging the plants of the region and corresponding with naturalists across the country. He died in 1863, having helped make West Chester a small hub of scientific learning.
The Williamson Free School of Mechanical Trades
Middletown Township, PA · est. 2013
Founded in 1888 by philanthropist Isaiah V. Williamson, this school set out to teach underprivileged young men a trade "free of expense," pairing hands-on instruction with a character-based curriculum. It emerged just as traditional apprenticeships were vanishing from American industry, making it a pioneering model of vocational education—and the only trade school in the nation to offer every student a full scholarship. Its campus also holds the largest surviving collection of buildings by the celebrated architect Frank Furness.
Hopewell Historic District
East Nottingham Township, PA · est. 1996
Chartered as a borough from 1853 to 1914, Hopewell was a small Chester County valley remade into a showcase of forward-looking farming, milling, and schooling. Drawn by its water power, the Dickey family developed the valley between 1815 and the 1870s, with Samuel Dickey earning a reputation as an agricultural innovator and his kin founding local schools. Much of that 19th-century landscape of fields and buildings still survives today.
