The fonds consists of a souvenir photograph album of the trip, possibly kept by G. Mayor-Cooke, the General Manager of Lang's company. Includes 31 snapshots of Lang, Mayor-Cooke and the rest of the company on board ship, and in locations enroute including Whitefisth Lake (Ontario), Winnipeg, Regina, and Edmonton; and 25 scenes along the route of the Canadian Pacific Railway (CPR) across the country from Quebec City to the West Coast. Most of the latter are commercial prints taken by Brigden Photos.
