File contains photographs documenting the construction of Cassiar's new mill building. Photos depict early excavation, foundations, framework, construction of all seven stories, sheeting, siding, and roof tarring. Also included are photos depicting the large model of the mill, as well as construction work done on the tramline. Photos taken inside the mill depict flooring work, and milling machinery including feed chutes, screens, fans, wheelabrators, control panels, electrical panels, conveyor systems, vacuum systems, and the fan-driven air system that transported the fiber. Many photos depict construction workers, building supplies, worksites, and equipment including cranes, bulldozers, tractors, hauling trucks and trailer flatbeds. Some photos depict aerial views from the new mill and feature the plantsite, tramline, mine road, mountains, and valley.

Photographs depict construction of the new mill, each taken from approximately the same distance and featuring two different angles of the building. Construction work progresses from framework to sheeting and siding. Vehicles, piles of building supplies, and a construction trailer are often in foreground, mountains in background. It is believed that these photographs were taken during a labour dispute. Each photo has been annotated on recto with the date and time of day, and some document the number of workers on site. Annotations include: "2 days work", "work gets less & less", "not much for 4 men", "very little done - less than usual low performance", "0° - 20° weather must have thickened their blood".

Photographs depict different construction projects at separate locations in Cassiar. Photographs were originally housed in envelopes with the following annotations: "POLICE STATION.
