This series contains personal diaries kept by Christina Barbara Hall, Benjamin Hall, and Charlotte Hall between 18 October 1795 and 8 May 1886. Christina Barbara Hall's diaries were written while she lived in Andover, Massachusetts, and in Montreal, Quebec. Benjamin Hall's diaries were written from Montreal and during a trip to London, England. Charlotte Hall's diary was written while she lived in Montreal. The diaries chiefly concern weather, news of family and community members, as well as occasional remarks about politics.

Each diary (or set of loose pages) was allocated a separate file because of the size and/or fragility of the volumes, and to maintain consistency within the series. Files in the series are arranged in chronological order. Diaries are mostly bound volumes, though Benjamin Hall's diaries are loose pages.

The administrative records series contains documents that reflect the structure and mandate of the Society, such as their constitution, acts, by-laws, yearly agenda, bookings, and membership lists. Summaries of meetings provide information of the NHSM’s interactions with other societies, notably the Horticultural Society, and also includes correspondence with society members, lists of addresses. An obituary of Society Librarian Charles Robb and an example of a membership certificate belonging to J. H. Joseph may also be found.
