Tint before we take ship at White House let us look at the size of the Yukon. The river is one of the largest of the world. There are only four on the North American continent that surpass it in length and in the area of the basin it drains. These are the Mississippi-Missouri, which rise far into the Buckles and is lost in the Mexican Gulf; the Winnipeg-Nelson that begins, with the Saskatchewan, in Southern Canada, and pours its waters into Hudson Bay, the Mackenzie that flows to the north and empties into the Arctic Ocean and the St. Lawrence, the downspout which carries the waters of the Great Lakes into the Atlantic. The length of the Yukon, from the source of its longest tributary to Berwick Bay, is as great as the distance from Boston to Salt Lake City, and the navigable streams which flow into it, if jointed together, would make a canal at low-draft steamers that would reach as far as from Seattle to Shanghai. The volume of the Yukon is about half that of the St. Lawrence and two-thirds that of the Mississippi-Missouri. It is three times as long as the Rhine, 600 miles longer than the Danube, and of just the same length as the Volga.
