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 glass plate negatives and prints of photographs assumed to have been taken by W.J. Moore of various locations in Coquitlam and Vancouver.
