How many slaves escaped along the underground railroad between 1810-1850

By one estimate, 100,000 slaves escaped from bondage in the South between 1810 and 1850. The southern newspapers almost every day were filled with announcements about new shoots of slaves, for catching of which the big reward was offered. There was even a special detachment of professional hunters for the fugitives who caught them and returned them back to the owner. But if the slave managed to reach the Canadian border, the persecution ceased. That's a rough estimate, but I hope it helps!!!

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
