Chree run. Conversion of the latter from wood-burning to oil-burning was carried out to overcome the noise made in loading wood, which had to be done at night and con- sequently disturbed passengers carried on the over-ni ght trip. Freight Movement The season of navigation extends for a period of approxi- mately 5 months, varying slightly in the spring. As previously stated, the first boat leaves Whitehorse down- tiver from May 15 to 25, and in the autumn the last boat leaves Whitehorse for Dawson on October 6 or 7, returning to Whitehorse October 16 or 17. During this period, the White Pass and Yukon Route boats handle their annual quota of freight. The following tabulation is indicative of normal freight movement: Tonnage of Freight Handled 1939 1941 1946 (a) Whitehorse-—Dawson.Y.T. 5,871 6,207 6,000 (b) Mayo-Whitehorse.

In peak years of production, heavy shipments of ore con- centrates were shipped by water from Mayo to Whitehorse, transhipped from that point by rail to Skagway, and thence to Seattle by ocean steamer, for final delivery at the smelter in Idaho. These silver-lead properties were reopened in 1946, and heavy shipments of ore are anticipated in 1947 and subsequent years. Tonnage handled in bond through Yukon Territory and consigned for points in Alaska, now consists mainly of supplies for the settlement of Eagle, and the mining districts of Coal Creek and Woodchopper Creek, or for settlements on upper Porcupine River in Canadian territory. Freight tariffs are available covering all movement of freight by water. Local tariffs are issued for movement of freight between points along the river, and through tariffs are issued covering joint movement of freight from Seattle, Vancouver, Victoria, and Prince Rupert, B.C., via ocean steamer, railway, and river steamers, to points along the Yukon Waterway. Practically all supplies from the Pacific Coast are handled on through tariffs; and this movement makes up the greater part of the total tonnage handled. Notes on Traffic Possibilities The volume of trafic on the Yukon Waterway from Whitehorse to Dawson and intermediate points will be {112} dependent largely on the requirements of the mining industry, now centred at Dawson and Mayo. Gold pro- duction in Yukon Territory showed a sharp decline following the commencement of World War II, due, mainly, to the acute labour situation which prevented the principal operators from using available equipment. With the end of the war, the volume of tonnage for mining purposes increased as former mining operations were rehabilitated and new prospects began to fit up for operation. New dredges were taken to Thistle and Henderson Creeks on the Yukon River. A start was also made on the estab- lishment of a lode gold operation near Carmacks, as well as the re-establishment of the mill for treating silver-lead ore at Keno Hill near Mayo. Prior to World War II, the White Pass and Yukon Route had built up a substantial tourist business, including round trips via Skagway, the Yukon River, and Seward, Alaska, or reverse. War-time restrictions on travel, however, greatly reduced this traffic. In 1942, the White Pass and Yukon Railway was taken over by United States military authorities, and its facilities were utilized mainly in the transportation of supplies required for Joint Defence projects, including the Alaska Highway and Canol Road and Pipeline. Until termination of the lease on April 30, 1946, necessary civilian requirements, including the trans- portation of passengers, express and freight were, however, maintained during the period of the lease. Prior to the cancellation of the lease held by the United States Army the road bed and the equipment of the railway was rehabilitated and put into first-class condition. A con- siderable tourist business was handled by both the railway and the river steamer lines during 1946 and there is every prospect of a similarly successful tourist season in 1947. As soon as scheduled passenger steamer service is established between Seattle, Washington, and Seward, Alaska, a weekly service from Dawson, Y.T., to Circle, Alaska, and return, will be inaugurated. The service will commence about June 1 and end in mid-September of each season. Connection will be made at Circle with bus stage-line for tourist passengers from and to Fairbanks and Anchorage, Alaska (6). The Yukon River route occupies a strategic position in the field of transportation in Yukon Territory, in that it offers the only medium for the transportation of freight at reasonable cost from railhead at Whitehorse to points downstream. Although air services (passenger and express) are maintained from Whitehorse to Mayo and Dawson the year round, very little freight is carried by air owing to prohibitive costs. Moreover, as yet, there is no all weather motor highway connections from Whitehorse to Mayo and Dawson, although these places are connected in winter by a tractor and truck route (the Overland Trail). No regular transportation services are maintained on the overland route between Whitehorse and Dawson.
