Henry Forrester’s working papers primarily document his domestic missionary activity in New Mexico and include four bound volumes of correspondence sent and received beginning with the final months of his rectorship in Terry, Mississippi (1874), through his early services in Santa Fe, Las Vegas, and Albuquerque. Also represented in the archive is a scrapbook volume titled “Forresteriana,” which covers the period 1871 to 1880 and includes clippings on topics of concern to him, news items on his work, published letters, and tracts written by Forrester for his work with the Spanish speaking population of the territory.
