The John Zug surveys consist of two notebooks containing sketches, measurements, calculations and notes about surveying various properties and laying out streets in Bowie, Maryland. One of the books, labeled "Field Book 1" on the front contains sketches probably made by John Edgar Zug (dated 1890-1891) and his son John Zug, Jr. (dated 1920-1922). The second book has sketches probably by John Zug, Jr (dated 1922-1937). The second book also includes three pages of genealogical information about the descendants of Robert Sewall (c. 1765-1820) and Polly Brant (c. 1772-1822).
The books contain information on property boundaries and land owners in Bowie in the late 19th and early 20th centuries.
