"The author wishes to thank the following generous scholars for sharing their knowledge with her: Elise Harding-Davis, curator of the North American Black Historical Museum in Amherstburg, Ontario; Nneka Allen, research assistant; Carl Westmoreland of the National Undergroud Railroad Freedom Center; and Jennifer Lushear, curator of education at the New Orleans Pharmacy Museum. The Freedom-Seekers: Blacks in Early Canada, by Daniel G. Hill, published in 1992 by Stoddart Publishing Company, Toronto, was also an invaluable resource. A special thanks to my editor, Amy Griffin, whose exquisite sensibility I greatly admire."
