Original photograph and negative sleeves, 1929-1931

Series III consists of seven boxes containing more than 900 photographs and negatives. Boxes 27-31 contain negatives and photographs donated by the Arnold Arboretum. They are arranged by negative number and therefore chronologically. Several negatives are permanently and irrevocably damaged, but have been kept with the collection. Box 32 contains the original, labeled envelopes created during the expedition. Box 33 contains loose photographs that were donated by Morse's family. These are numbered and identified in a different manner than those in boxes 27-31. Most of the photographs in this series are included in either the journals in series I, the photograph albums and scrapbooks in series II, or in some cases, both. Many of the photographs in series I and II, however, are not included here.

The photographs and negatives contained in this series are listed in a database detailing their subjects and quality. For assistance in locating and using this database, please contact a staff member of Special Collections.
