PREFACE. The undersigned herewith introduce the correspondence between them, which gave rise to the debate in which they have been engaged, and which is substantially contained in the following pages. In presenting the following work to the American public, no apologies are offered. Me live under a Government which tolerates liberty of thought, liberty of speech, and freedom of the press and in this ex pression of our honest views and feelings-differing widely as we do - upon the subject of Domestic Slavery in the United States - a subject relating to the general welfare of the country, we are but exercising a right which belongs to every American R citizen. The age of proscription for opinions sake, is4 past, and, as me trust, never again to return. The liberal genius of our free institutions, allows to all unrestricted interchange of thought and sentiment while mens opinions are received or rejected, accord ing as they possess merit or demerit For the imperfections of this volume, the undersigned offer no apology. The Lectures of each mere prepared for the occasion, under the pressure of other important, and frequently distracting avocations. We both claim to have spoken honestly, and with a sincere desire to do good. . One of us a Southern man, the other a Northern man-both prejudiced, as me frankly admit, at least to some extent, in our educations, habits, and associations, in favor of the institutions, and usages of the respective section of the country me hail fromthe reader will appreciate our principles and opinions, as he may deem them entitled to favor.
