The Negro in Pennsylvania - Slavery-Servitude-Freedom, 1639-1861 #225308

Last of all it is a pleasure to acknowledge the partien lar obligations under which I am to my friend, Mr. Albert Cook Myers of Moylan, Pennsylvania. Not only did he help and encourage me at every stage of my task, but with rare generosity he put at my disposal all of his own collections and his vast knowledge of the location of the sources for Pennsylvania history. At his suggestion and through his recommendation I used manuscripts which I could not have obtained otherwise. Not a few of the facts contained in my book were fur nished by him directly.
