UNDERGROUND RAILROAD - PAGE 15

The Underground Railroad, a vast network of people who helped fugitive slaves escape to the North and to Canada, was not run by any single organization or person. Rather, it consisted of many individuals -- many whites but predominently black -- who knew only of the local efforts to aid fugitives and not of the overall operation. Still, it effectively moved hundreds of slaves northward each year -- according to one estimate, the South lost 100,000 slaves between 1810 and 1850.
