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 b&w glass negatives depicting the barn buildings, animals, and farm workers at Colony Farm, as well as some unidentified locations.

This series consists of records related to the construction and operations on Colony Farm at Riverview Hospital. The materials relate to the original construction planning and dyking done to create Colony Farm, as well as some of the early auction and sale records of cattle and horses.

Record types include correspondence, financial records, agreements, receipts, a certificate, and policy material.
