In 1897, Adney went to the Klondike as an artist and special correspondent for _Harper's Weekly_ and _The London Chronicle_, to report on the gold-rush. He also wrote a book on his experience, _Klondike Stampede_, published in 1900. In 1899 he married Minnie Bell Sharp, of Woodstock, but by 1900 Adney was again in the Northwest, this time as special correspondent for _Colliers_ magazine at Nome, Alaska, during the gold-rush of that year. On his return to New York, Adney engaged in illustrating outdoor scenes and also lectured for the Society for the Prevention of Cruelty to Animals. In 1908 he contributed to a Harper's Outdoor Book for Boys. From New York he removed to Montreal and became a citizen of Canada, entering the Canadian Army as a Lieutenant of Engineers in 1916. He was assigned to the construction of training models and was on the staff of the Military College, mustering out in 1919. He then made his home in Montreal, engaging in painting and illustrating. From his early years in Woodstock he had made a hobby of the study of birch-bark canoes, and while in Montreal he became honorary consultant to the Museum of McGill University, dealing with Indian lore. By 1925 Adney had assembled a great deal of material and, to clarify his ideas, he began construction of scale models of each type of canoe, carrying on a very extensive correspondence with Indians, factors and other employees (retired and active) of the Hudson's Bay Company, and with government agents on the Indian Reservations. He also made a number of expeditions to interview Indians. Possessing linguistic ability in Malecite, he was much interested in all the Indian languages; this helped him in his canoe studies. Owing to personal and financial misfortunes, he and his wife (then blind) returned in the early 1930's to her family homestead in Woodstock, where Mrs. Adney died in 1937. Adney continued his work under the greatest difficulties, including ill-health, until his death, October 10, 1950. He did not succeed in completing his research and had not organized his collection of papers and notes for publication when he died. Through the farsightedness of Frederick Hill, then director of The Mariners' Museum, Newport News, Virginia, Adney had, ten years before his death, deposited in the museum over a hundred of his models and a portion of his papers. After his death his son Glenn Adney cooperated in placing in The Mariners' Museum the remaining papers dealing with bark canoes, thus completing the "Adney Collection."
