As many locals were aiding the escape of slaves, the author chronicles the events that led to the draft of the Fugitive Slave Law in 1793, by which helping slaves escape was declared as an offence. This high level of ill-treatment resulted in the deep desire among the slaves to attain freedom. At this time, they also began to hear about the favorable condition in Canada. Soon, the Underground Railroad system began to develop in Ohio, Iowa and Illinois. The author further talks about the abduction of slaves from the south and how the local people assisted in helping t he slaves escape and lead a better life in a place where they have enough freedom.

Torrey, Calvin Fairbank and so on.
