Series VI. Diseases and Pests of Japanese Cherry Trees, 1910-1975

Series VI contains materials compiled by Roland Jefferson which relate to the diseases and pests of Japanese cherry trees imported to the United States. Materials are primarily photocopies of original documents and include memoranda, correspondence, telegrams, newspaper clippings, reprints, and Jefferson's own correspondence and research notes. Correspondence and memoranda from officials in the National Park Service (NPS) and the United States Department of Agriculture (USDA) account for the bulk of materials. Topics covered include the infestation of the first gift of Japanese cherry trees in 1910; pests and diseases introduced to the United States by Japanese cherry trees; and USDA Quarantine 37 regulations preventing the import of a gift of trees from Japan during the administration of President Lyndon Baines Johnson. This series is arranged chronologically.
