PREFACE.
It is the object of this work to compare the condition of the
slaveholding and non-slaveholding States—the North and the
South—as to territory, population, industry and wealth, education
and intelligence, religion and moral advancement, and
general progress. The authorities used are the official documents
of the General Government and of the individual States.
The calculations are, for the most part, for the year 1850, and
based on the census returns for that year, as compiled by J. D.
B. De Bow, and published in his Compendium of the Seventh
Census.
This work, prepared with much labor, is the only one of the
kind within our knowledge. We think there is public necessity
for it, and submit it without further remark.
Concord, Mass., September, 1856
