Baltimore (Md.) -- Economic conditions -- History -- Sources

This collection consists of the correspondence and business records of Isaiah S. and Martha Lang, New Hampshire farmers. It includes significant groupings of letters from Isaiah Lang's uncle, David M. Sanborn, a Baltimore physician, and from relatives farming on the Minnesota frontier. The letters from Sanborn are especially interesting in light of their particular references to economic and social conditions in a "border state" immediately before and during the Civil War.
