09499. SLAVERY AND GEOGRAPHY IN THE UNITED STATES. Analyzes the impact of geography and climate upon the spread of slavery and survival or destruction of slavery populations. Argues that slavery became essential to the Southern economy not because Southerners were inherently more predatory and inhuman than Northerners, but because land, climate and agricultural economy of the south required a different system of labor than that of the north. 10 pages, 16 footnotes, 11 bibliographic sources.
