Records of the organization form the bulk of the collection. Included are some correspondence from 1893 to 1959. Different types of ledgers document the finances, with some type of coverage from 1876 to the 1950s. There are gaps in several of the financial series, with some types of documents covering only certain date ranges. For example, the “Journals” cover the years 1876 to 1903 only. Pension rolls exist for 1909 to 1929. Minutes cover 1891 to 1934. Membership applications, certificates and registers cover 1893 to 1919. Most of these documents are housed in old ledge type volumes which would be damaged by photocopying or scanning, the use of a non-flash camera to copy these items is preferred.
