One photograph album kept by a member of the Canadian Society of Civil Engineers documenting a Canadian west coast trip through the provinces of Manitoba, Saskatchewan, Alberta and British Columbia. The 120 silver gelatin photographs show images of interest to the engineers including elevators, irrigation works, mines, smelting works and power plants as well as the scenery of the Rocky Mountains and local people and wildlife. Of particular note is the fact that the party contained numerous women, not all of whom were wives. The front of the album has a pastedown listing all participants in the tour and the back a pastedown listing captions for all of the images.
