The subseries consists of photographs thought to have been taken by W.J.Moore although it is possible they were taken by another photographer. The assumption of provenance has been assumed based on the context in which the negatives were found. It has not been possible to confirm. The photographs depict the buildings, livestock, farm workers (likely Essondale patients), and employees of Colony Farm and Essondale (Riverview Hospital). The subjects consist primarily of cows and horses, as Colony Farm was known across the province for the quality of its livestock. It was awarded a master breeder shield in 1930 from the British Columbia Branch of Holstein Canada. Many of the agricultural photographs also show Essondale's West Lawn building at various points in its construction.

The subseries consists of 13 b&w glass plate negatives depicting the West Lawn building, which opened in 1913, as well as interior shots of various labs and lounges, and the dormitory. There is also a photograph of an unidentified building, and an interior shot of the shoe workshop at the Provincial Hospital for the Insane in New Westminster, B.C.

The series consists of photographs predominantly depicting aspects of social and administrative life at Riverview Hospital and the School of Psychiatric Nursing as well as and Colony Farm. The photographs in the series portray the everyday social life of Riverview Hospital staff and volunteers as well as events, meetings, gatherings, and kinds of work they undertook. Additionally the series depicts scenes of Riverview Hospital's many buildings in varying states of completion, portraits of prize winning livestock (Holstein cattle, Clydesdale and Belgian horses), scenes during periods of flooding at Colony Farm, and equipment, vehicles, and technology used by the Hospital.

The glass plate negatives in Subseries 01 and 04 are known to have been taken by W.J. Moore, a prominent Vancouver photographer. It is possible that the entire collection was taken by W.J. Moore, although it has not been possible to confirm. Some photographs in Subseries 02 are thought to depict the Provincial Hospital for the Insane in New Westminster. Photographs in Subseries 04 are also thought to depict the Dominion Experimental Farm in Agassiz, B.C.
