The series consists of original incoming letters, missionary journals, reports, indents, estimates, accounts, local CMS and diocesan committee minutes, medical certificates, maps, sketches, translations into Indian syllabic characters, etc. It includes correspondence for the North-West America Mission, 1822-1880 (Class "C", Series C.1./O., designated Appendix B in Finding Aid 23) and 1880- 1930 (Class "G", Series C.1./O), which includes microfilmed material, 1880-1900, designated Appendix D in Finding Aid 23, and microfiched material, 1901-1930, that is not included in the detailed lists and indexes in Finding Aid 23. This latter material is on microfiche nos. 1-65.
It also includes correspondence of the North Pacific Mission, 1857-1880 (Class "C", Series C.2./O., designated Appendix C in Finding Aid 23), and 1884-1925 (Class "G", Series C.2./O.) which includes microfilmed material, 1884-1900, designated Appendix E in Finding Aid 23, and microfiched material, 1901-1925, that is not included in the detailed lists and indexes in Finding Aid 23. This latter material is on microfiche nos. 66-95. It should be noted that the material in Appendix E was both filmed and listed in a dislocated sequence that is clarified in the categorical list supplied in Finding Aid 23.
A number of items in this series, particularly financial papers as distinct from financial letters, are noted as having been removed, especially from the later Class "G" parts of the material. Their substance can often be found recorded in the Précis Books described below. All the microfilmed material is indexed in Finding Aid 23, giving references to the Appendices and to the item numbers assigned in them. It should be noted that the material near the beginning of Appendix B that is arranged topically or alphabetically by the names of the correspondents is listed, and therefore indexed, in less detail than the rest of the material, which is arranged chronologically by date of receipt. The microfiched material is not indexed.
