Series 1 consists of materials closely associated with the life of WSC, not including third-person biographical accounts, which are in Series 4. "Personal Association Items" are those for which there is evidence or a strong presumption of their having been in WSC's possession.

The materials in Subseries 1: College, Military, and Other Biographical Records, include the Clark family record, apparently in WSC's handwriting; his biographical form prepared for the AC alumni records; excerpts from books and records regarding WSC and family members (folder 1); his grandson WSC II's AC graduation certificate (oversize Box 27); a number of obituaries, including one by UCHIMURA Kanzo, who was later to become a prominent Christian leader in Japan (folder 2); copies of WSC's military service records and a letter from Major General A.E. Burnside to Major General George B. McCellan recommending WSC for promotion to Brigadier General (folder 3); accounts of the 21st Regiment Volunteers (folder 4); Civil War newspaper clippings, including WSC's own accounts of the battles of Newbern and Camden, and the erroneous account of his death in battle (folder 5); miscellaneous printed items, including many newspaper clippings (folder 6 and oversize Box 27); materials relating to the introduction of Japanese trees into the United States (folder 7); and photographs of the log maintained atop Mt. Shasta, with Clark's signature on June 16, 1877 (oversize Box 27).

Subseries 2: Personal Association Items, includes WSC's passport for his European trip (folder 8); his notebook used at Georgia Augusta University in Goettingen, consisting of his lecture notes from a course in "economical botany" and detailed notes in German by someone else, which seem to be a condensation of a book or study notes (folder 9); WSC's AC catalogue of 1855-56 with his record of student rent payments (folder 10); pictures and sketches sent from Germany (folder 11); a scrapbook of clippings, largely farm animals, 1860, n.d. (folder 12); a MAC library poster issued over WSC's name (folder 13); an inventory of Ainu objects and other artifacts sent by WSC to MAC from Japan (folder 14); a lithograph of Commodore Perry at Hokudai (folder 15); and WSC's lists of Japanese lichens and phenograms (folder 16).

Subseries 3: Photographs and Pictures, is arranged into the following categories: WSC alone (folder 17); WSC's office and classroom at MAC, c. 1876 (folder 18); family, including what is probably a honeymoon picture, and the group photograph of his family which is probably the one he had in his quarters in Sapporo (folder 19); the family home in Amherst (folder 20); WSC, students, and faculty of SAC (folder 21); farewell photograph taken in Sapporo, April 16, 1877 (folder 22); photographs of various memorials to WSC (folder 23); a family scrapbook with photographs of WSC's friends and descendants in the last pages (folder 24); a photocopy of a photograph of WSC with HORI Seitarō and several Karafuto (Sakhalin) Ainu, from a Peabody Museum of Salem publication (folder 25); photographs of an exhibit prepared by ŌSAKA Shingo, (original paintings by SUNAGANE Takashi from the exhibit in Box 28; see information below on the exhibition, "A Pictorial Life of Col. William Clark") (folder 26); and a tree planting ceremony at WSC's grave. May 18, 1973 (folder 27).

In the farewell picture WSC has tentatively been identified after careful analysis by AKIZUKI Toshiyuki, head of the Reference Division of the Hokudai Library, as the figure with the light colored hat on the horse second from the right.

The exhibition, "A Pictorial Life of Col. William Clark" was prepared by the Rev. ŌSAKA Shingo, the Japanese biographer of WSC. He wrote the narration which appears on the backs of the series of original paintings by SUNAGANE Takashi titled, "The Picture Story of Our Dr. William Smith Clark, from 1826-1876", filed in oversize Box 28. This series of watercolors was part of ŌSAKA's exhibit prepared to commemorate in Hokkaido the 1961 centennial of WSC's going off to fight in the Civil War. It was displayed in the American Cultural Center in Sapporo and in many primary schools in Hokkaido.

The tree planting ceremony took place at the Clark Family plot in West Cemetery, Amherst, on May 18, 1973. The tree was a cherry descended from the one that Professor William Brooks, WSC's student who joined him in Sapporo, brought back from Japan. It was presented by the late Professor William Colby, who served as a visiting professor at Hokkaido University in the early 1960s.

Housed with this collection, but not part of it, is the photograph album of G.A. Parker, Class of 1876, which includes additional photographs of WSC and his family, and the MAC campus at the time of WSC's presidency. See RG 130/1876.

Series 2 consists of two broad categories of correspondence-personal, and official. The personal correspondence covers WSC's student days at AC, his period of study in Europe, his service in the Civil War, his mission to Hokkaido, and his subsequent communications with his Japanese students and officials. The official correspondence deals with his mission to Hokkaido, and to a limited extent with his presidency of MAC.

Much of the personal correspondence in the collection and the letters dealing with his MAC presidency are originals but are in fragile condition and therefore are available as photocopies to minimize handling. The photocopies are filed in Box 4; the originals owned by the University of Massachusetts Amherst are in Box 5. All photocopies in Box 4 for which UMass owns an original in Box 5, are designated by "(*)" on the container list. Those items which are photocopies of originals at Amherst College are designated by "(AC)" on the container list.

The official correspondence dealing with Hokkaido consists of originals held by UMass and photocopies of originals in the possession of Hokudai. Photocopies from Hokudai originals are indicated by "(HU)" on the container list. Copies of official Hokkaido correspondence in the possession of UMass are in turn available at Hokudai. Copies of additional correspondence regarding Hokudai can be found in Special Collections and University Archives in the papers of William Wheeler (RG-2/3), David Penhallow (RG-50/6-1873) and Horace Stockbridge (RG- 40/11).

What follows here is a general description of the items in Series 2. The Container List identifies each individual item.

Folder 1 consists almost entirely of letters from WSC to members of his family while he was a student at AC. These letters provide insight into the happy family relations between him and his parents and his sister Harriet. His accounts of life as a student reveal a great deal about college life at AC. The most significant incident covered by these letters is his religious conversion, reported in a letter to his mother March 16, 1846.

Folder 2 contains twenty-one letters dated 1850-1852, mostly to his parents and three sisters while WSC was in Europe. These are particularly valuable because of the detailed descriptions of what WSC observed both in England and in Germany.

Folder 3 contains his honeymoon letter to his parents, dated May 30, 1853 from Charleston, Virginia, and two other letters.

Folder 4 contains his Civil War letters to his family and Amherst friends. They reflect his shift in attitude towards war, from that of his early weeks in the army when he relished the glory and romance, to his final view that war is death, suffering, and hardship. These letters shed more light on his close family ties.

Folder 5 contains a fragment of a letter to his father in 1865.

Folder 6 contains the small number of letters dating from his presidency of MAC. About half of these letters relate to Japan and his mission to Hokkaido. The items most directly concerned with MAC are the two letters dealing with the junior class protest regarding selection of speakers for Commencement Week, 1872. Of interest is a request from Japanese ambassador YOSHIDA Kiyonari for WSC to speak in favor of treaty revision.

Folders 7-12 contain official correspondence relating to Hokkaido, which has been organized chronologically as follows in order to illuminate the development and flow of WSC's work:

Folder 7. Jan to Mar 1876. Preliminaries and Contract Folder 8. Jul to Aug 1876. Preparations, Initial days at SAC Folder 9. Sep 1876. First Month of Intensive Operations Folder 10. Oct to Dec 1876. The Middle Period Folder 11. Jan to May 1877. Preparations for Departure and Farewells Folder 12. 1877 to 1880. Continued work for SAC after return to US

The Container List has been annotated to show the contents of most items in these folders.

Duplicates of some of the photocopies of the official correspondence are filed in Box 24. An attempt was made to file the most legible copy in Box 4; particular words, however, might be clearer on the duplicate copy. See also folder 13, which contains typescripts of those letters from WSC to Japanese officials indicated by "(t)" on the Container List for folders 7-12. Folder 13 also includes typescripts of two letters (originals at HU) to students which are not represented by photocopies: WSC to Mr. Y. KUROIWA, March 11, 1879 from New York, and WSC to UCHIDA, December 25, 1883 in Amherst.

The William Wheeler papers (RG-2/3) and WSC's letters to his wife and children (folder 14) are excellent supplements to the official correspondence because of the additional information they provide on the voyage to Hokkaido and WSC's operations with the Japanese in Hokkaido.

Folder 14, as mentioned above, contains WSC's correspondence with his family while he was in Hokkaido. These letters are valuable not only for the descriptions of WSC's experiences and work in Hokkaido, but also for what they tell us of the warmth of his relationships with his wife and small children. The letters from WSC to his wife are typed copies which were presented to the University of Massachusetts Amherst by Mrs. William S. Clark II. Where the originals are and who copied them are unknown. Both the content and a careful comparison of the style of these copies and other WSC letters leave little doubt as to their authenticity. The folder of the photocopies includes typed transcripts of the two letters to brother-in-law William B. Churchill and to Sister Belle, as well.

Folder 15 contains subsequent correspondence with Clark's Japanese students and two of the officials WSC dealt with while in Hokkaido. These letters reveal the close ties that developed between WSC and his students. They contain, in addition to expressions of feeling, news about SAC and Hokkaido and many references to the students' religious concerns.

Folder 15a includes typescripts of all the letters in folder 15, as well as three additional ones, the originals of which are at HU. See also folder 13.

Folder 16 contains miscellaneous items which do not fit well into any of the above categories. The most significant are the 1884 and 1885 letters (originals at HU) to William P. Brooks, the last known to have been written by WSC before his death in 1886. A letter from WSC's son, Atherton, to MAC Secretary Robert Hawley in 1930 indicates that WSC's papers were scattered or destroyed when the family home in Amherst was broken up.

Folder 17 contains photographs of letters (originals at Doshisha) from WSC to Joseph NEESIMA, written between 1878-1882.

Series 3 consists of 20 items, most of which are published versions of public lectures delivered by WSC, a situation flowing naturally from the fact that he was famous as a lecturer.

Three books are included: (folder 2), his doctoral dissertation published in 1852; his translation of Theodore Scheerer's (folder 7), published in 1869; and (folder 17), edited and with a bibliography by YAMAMOTO Tamaki, Hokkaido University, published in 1993.

"Report on Horses" (folder 3) was written while WSC was a professor at AC and was active in the Hampshire (County) Agricultural Society.

The seven publications here from his MAC years, excluding , include four relating to his role as President and three which can be described as research papers. The four presidential writings are "The Work and the Wants of the College" (folder 4), "Rules for the Agricultural Department, MAC" (folder 5), "Professional Education the Present Want of Agriculture" (folder 8), and "The Relations of Botany to Agriculture" (folder 9). The three research papers are "The Circulation of Sap in Plants", "Nature's Mode of Distributing Plants", and "Observations upon the Phenomena of Plant Life". All of these publications illustrate the development of the scientific study of agriculture in the formative years of this land-grant school.

The sap circulation study was a source of controversy. Although there is no contemporary account of it, the daughter of Professor Selim Peabody, then a MAC professor, wrote some years later that her father was responsible for the research and that WSC, as President, had simply placed his name on the report. "A Lecture on the Flow of Sap and the Power of Plant Growth", found in WSC's 12th Annual Report of the MAC, and "Observations upon the Phenomena of Plant Life" both include an account of the famous experiment which measured the power created by the growth of a giant squash.

WSC's own record of what he accomplished and observed in Japan is to be found in the "First Annual Report of Sapporo Agricultural College" (folder 14) and "The Agriculture of Japan" (folder 16). The latter demonstrated WSC's powers of observation and reporting, also revealed in his correspondence.

The "Covenant of Believers in Jesus" (copy in folder 15, original in oversize Box 27) was composed by WSC and signed by all of the students in the first freshman class at SAC. It is evidence of his success as an informal missionary, because it was a major step in the eventual baptism of the students, an event which took place several months after WSC's departure from Japan.

Series 4 contains a wide variety of material touching on his life and work, and is divided into seven subseries. It includes correspondence about him, reminiscences and biographical sketches, books and articles about him, materials compiled for a biography, and audio-visual materials about his life.

Box 7, folders 1-6, contain Subseries 1: Correspondence about WSC, the bulk of which (folders 2-5) is dated 1940 or later and provides little fresh information about WSC. The most significant letter is that by Dr. MIYABE Kingo (folder 1) on the plans for a Clark memorial church in Sapporo.

Folder 6 contains material relating to the William Smith Clark Association, an informal group made up of Amherst residents, mostly from the University of Massachusetts, who were concerned with Amherst's relations with Hokkaido and HU. It was created mainly to plan the UMass contributions to the celebration of the Hokudai centennial (and, of course, the centennial of WSC's mission to Hokkaido) in 1976.

Boxes 8 and 9 contain Subseries 2: Reminiscences and Biographical Sketches. Many of the items listed contain only brief references to WSC, which contribute little to an understanding of him but do reveal the extent to which he became and has remained well known in Japan. The most valuable items include reminiscences by WSC's son Atherton (folder 12); the writings of MIYABE (folder 29), ŌSHIMA (folder 33), and Bowker (folder 10), all former students; and the article by David P. Penhallow (folder 35).

The article, "Boys, Be Ambitious" from the , 1981 (folder 31), a middle school textbook used nationally in Japan, shows how WSC is remembered more than a century after his mission to Hokkaido.

Boxes 10 and 11 contain Subseries 3: Books, which deal wholly or in part with the life of WSC. Brief comments on some of the principal titles are given below:

, by ŌSAKA Shingo, Sapporo 1956 (folder 53), is the definitive biography in Japanese by the man who was the foremost Japanese authority on WSC. This long biography was written without the benefit of access to much material which became available after its publication. , by ŌSHIMA Masatake, 1943 (folder 54), is of value because its author was one of WSC's students at SAC. [on verso of t.p.: ], by ŌTA Yūzō, Tokyo, 1979 (folder 55), written by a McGill University history professor, consists primarily of translations of Clark's letters to his family at Sapporo that are found in Series 2. from the Hokkaido Prefectural Government, 1968 (folder 47-48), contains brief biographies of a number of foreigners, the majority Americans, who played roles in the early development of Hokkaido. , by John Maki, translated by TAKAKU Shin'ichi, Hokkaido University Press, 1978 (folder 51), See Boxes 12 and 13.

Boxes 12 and 13 contain Subseries 4: John Maki Manuscript, which includes a photocopied typescript of by John Maki; the author's account of how he came to write it; and a J.F. Howes review of the book from . It is the only book length biography of Clark in English.

Box 14 contains Subseries 5: Background Materials for Maki Biography of WSC. The materials, compiled by John Maki for use in writing , consist primarily of photocopies and transcriptions of sections of books, and articles, booklets, and newspaper clippings.

Box 15 contains Subseries 6: Notes for Maki Biography of WSC, which consists of twelve envelopes of handwritten and typed notes on 4 x 6 index cards, compiled by John Maki for writing his biography of WSC.

The materials in Boxes 14 and 15 are particularly useful with regard to WSC's presidency of MAC, his early contacts with Japanese students in Amherst, the floating college, and WSC's mining venture.

Boxes 16-18 contain Subseries 7: Television, Radio, and Other Audio Visual Materials. The major item is a videotape of a television program broadcast on a Japanese national network on November 3, 1981 (Culture Day, a Japanese national holiday). There are three different video cassettes (VHS, Beta, and 3/4 inch videotape cassettes) of (folders 76-78). Also included are the Japanese language script of the program (folder 80); , which is a book length account, including much of the life of WSC, of the making of the program by the TV crew that filmed it (folder 81); "The Filming in Amherst of the Japanese Television Documentary on the Life of William Smith Clark" by John Maki (folder 82); and correspondence and clippings relating to the program (folders 83-85).

Other materials in Subseries 7 include an audiotape of a radio interview of John Maki on WSC, an audiotape and a silent film of the tree-planting ceremony at the Clark family grave on May 18, 1973, and videotapes regarding the Massachusetts / Hokkaido Sister State relationship and the WCS Memorial.

Subseries 1: Chronological Record, consists of materials which document the continuing relations of SAC / MAC from the time of Clark's presence in Japan through the growth of each school into a university. The materials reflect exchanges, both formal and informal; influences, especially that of Massachusetts professors on SAC/HU; gifts, visits, and honors through correspondence and memoranda; typescript and printed articles; clippings, press releases, and brochures; mementos, photographs, and pictures; and prepared lists.

In Subseries 2: Summer Seminar 1974, the experience of the seminar is revealed through the journal of Professor Richard Woodbury, as well as in the schedules, lecture notes, participant evaluations, photographs, travel arrangements, souvenirs, memoranda, and printed materials.

Subseries 3: Books on HU, includes early annual reports, 1877-1879; histories of HU in English and Japanese; HU catalogs, 1921-1922 and 1936-1937; a catalog of the holdings in the SAC library, 1888; lists of plants in the HU Botanical Garden; and other books. Also see Subseries 1, folder 9.

Selected duplicates, mainly from the Hokkaido Official Correspondence and Clark's writings. Other duplicates are often found filed with their counterparts.

Miscellaneous artifacts associated with the legacy of William Smith Clark.
