Amateur film. Shows the operation and construction of B.C. Spruce Mills' 14-mile-long Moyie River flume. The construction scenes were probably shot during the building of a branch flume in 1926, as the Nigger Creek Crossing (which is the most impressive single engineering feature on the system) is seen completed.
