This fonds contains largely original material documenting E. Tappan Adney's long involvement in the affairs of native people in New Brunswick, particularly the Maliseet. It includes information about treaty rights, New Brunswick court cases involving native rights, the historical development of reserves, and the 1947 review of the Indian Act.
This fonds contains correspondence, newspaper clippings, reports, briefs, submissions, notes, and copies of published articles, treaties, speeches, proclamations, and "deeds". It also includes several photos, prints, sketches, and watercolours. Some materials are typescripts.
There is also a microfilmed copy of Adney's diary covering his first trip to New Brunswick (30 June 1887 to 28 February 1889) as well as his diary covering his second trip to New Brunswick and first trip to Nova Scotia (July to November 1890).
