Professional and letters written or received by William Milnor Roberts or his son, Milnor Roberts. Writers include many people associated with the engineering projects in which Roberts was engaged. Of particular note are: letters written by Roberts to his wife, Adeline, during his 1869 reconnaissance of the Northern Pacific Railroad route through Washington, Idaho, and Montana; a file of letters on engineering matters written to Henry S. Drinker; letters pertaining to Roberts' work in Brazil during both of his visits there. Letterpress copies of Roberts's outgoing correspondence were separated from the volumes prior to their donation to MSU. The damaged volumes, which contain indices to the letters, have been retained with the letters in this series. The letters have been chronologically arranged.

Personal diaries, travel logs and engineering notes compiled by William Milnor Roberts throughout the latter part of his adult life. Some volumes are personal diaries, recording Roberts' daily activities and impressions of people, places, and events. Other logs and notes are more professionally oriented, recording Roberts' observations of landscapes, geographic features, and engineering problems. Occasionally the personal and professional writings overlap, and both were likely used by Roberts to compile his lengthy written reports and essays in Series 4. The journals document Roberts's travels in the western United States (especially the northwest), Europe, and Brazil. Notes in box 5, folders 6-9 are either unidentified or memoranda Roberts recorded from his readings.

Membership certificates, professional credentials, and legal documents pertaining to William Milnor Roberts or his son, Milnor Roberts. Included are testimonial letters written by former employers and professional colleagues prior to Roberts' departure for Brazil in 1857. Oversize documents have been removed to Box 8, folder 4

Many of the reports were later published in booklet and pamphlet form and have been retained in Series 5, printed materials. The reports in this series cover every major engineering project on which Roberts worked during the latter portion of his career, including those in Brazil and those undertaken for the Northern Pacific Railroad. Also included are essays of a general nature Roberts wrote on various topics, such as life in Brazil, the nature of gravity and American government.
