. The Underground Railroad benefited greatly from the geography of the U.S.–Canada border: Michigan, Ohio, Pennsylvania and most of New York were separated from Canada by water, over which transport was usually easy to arrange and relatively safe. The main route for freedom seekers from the South led up the Appalachians, Harriet Tubman going via
Harpers Ferry, through the highly anti-slavery
Western Reserve region of northeastern Ohio to the vast shore of Lake Erie, and then to Canada by boat. A smaller number, traveling by way of New York or New England, went via
Syracuse (home of
Samuel May) and
Rochester, New York (home of
Frederick Douglass), crossing the
Niagara River or
Lake Ontario into Canada. By 1848 the
Niagara Falls Suspension Bridge had been built—it crossed the Niagara River and connected New York to Canada. Enslaved runaways used the bridge to escape their bondage, and Harriet Tubman used the bridge to take freedom seekers into Canada. Those traveling via the New York
Adirondacks, sometimes via Black communities like
Timbuctoo, New York, entered Canada via
Ogdensburg, on the
St. Lawrence River, or on
Lake Champlain (
Joshua Young assisted). The western route, used by
John Brown among others, led from Missouri west to free Kansas and north to free Iowa, then east via Chicago to the
Detroit River.
Thomas Downing was a free Black man in New York and operated his Oyster restaurant as a stop on the Underground Railroad.
Freedom seekers (runaway slaves) escaping slavery and seeking freedom hid in the basement of Downing's restaurant. Enslaved people helped freedom seekers escape from slavery. Arnold Gragstone was enslaved and helped runaways escape from slavery by guiding them across the
Ohio River for their freedom.
William Still, sometimes called "The Father of the Underground Railroad", helped hundreds of slaves escape (as many as 60 a month), sometimes hiding them in his
Philadelphia home. He kept careful records, including short biographies of the people, that contained frequent railway metaphors. He maintained correspondence with many of them, often acting as a middleman in communications between people who had escaped slavery and those left behind. He later published these accounts in the book
The Underground Railroad: Authentic Narratives and First-Hand Accounts (1872), a valuable resource for historians to understand how the system worked and learn about individual ingenuity in escapes. According to Still, messages were often encoded so that they could be understood only by those active in the railroad. For example, the following message, "I have sent via at two o'clock four large hams and two small hams", indicated that four adults and two children were sent by train from
Harrisburg to Philadelphia. The additional word
via indicated that the "passengers" were not sent on the usual train, but rather via
Reading, Pennsylvania. In this case, the authorities were tricked into going to the regular location (station) in an attempt to intercept the runaways, while Still met them at the correct station and guided them to safety. They eventually escaped either further north or to Canada, where slavery had been
abolished during the 1830s. To reduce the risk of infiltration, many people associated with the Underground Railroad
knew only their part of the operation and not of the whole scheme. "Conductors" led or transported the "passengers" from station to station. A conductor sometimes pretended to be enslaved to enter a
plantation. Once a part of a plantation, the conductor would direct the runaways to the North. Enslaved people traveled at night, about to each station. They rested, and then a message was sent to the next station to let the station master know the escapees were on their way. They would stop at the so-called "stations" or "depots" during the day and rest. The stations were often located in basements, barns, churches, or in hiding places in caves. The resting spots where the freedom seekers could sleep and eat were given the code names "stations" and "depots", which were held by "station masters". "Stockholders" gave money or supplies for assistance. Using biblical references, fugitives referred to Canada as the "
Promised Land" or "Heaven" and the
Ohio River, which marked the boundary between
slave states and free states, as the "
River Jordan". == Traveling conditions ==
