Each one of the branches of the River in this plateau region has one or more of these expansions. On the Columbia itself are the Arrow Lakes. Kootenai Lake is an enlargement of the River of the same name. Okanogan Lake is likewise an expansion of its river. Christina Lake is the source of Kettle River. The Slocan River derives its icy torrents from Slocan Lake. Flathead, Kaniksu, and Pend Oreille lakes feed Clark's Fork, now more commonly known in its lower section as Pend Oreille River. Coeur d'Alene Lake supplies the Spokane River. Chelan pours its cold flood into the Columbia through a river of the same sweet sounding name. Wenatchee Lake gives life to the Wenatchee River. We find at Revelstoke that the chief current of tourist travel follows the main line of the Canadian Pacific Railroad. Nevertheless, there is a rapidly increasing movement of travellers on the branch by steamboat over the Arrow Lakes and the Kootenai to what is known as the Crow's Nest line from Spokane to Calgary, Winnipeg, and other points east. The Canadian Pacific line has excellent steamers, the _Rossland_, the _Kootenai_, the _Kaslo_, the _Kuskanook_, and others of similar grade. The journey on the _Rossland_ or _Kootenai_ down the Arrow Lakes from Arrowhead to Robson is one to dream of, one to recall in waking hours, and even, we almost suspect, in another life. The two lakes together constitute one hundred and thirty miles of steamboating, and every mile has its special charm. It was the peculiar joy of the _voyageurs_, after having toiled over the snowy and wind-swept Athabasca Pass and buffeted the foamy descent of Death Rapids, to reach the Arrow Lakes and lazily paddle down their tranquil deeps. In fact, pleasant as is our journey on the _Rossland_, we would rather reconstruct the bateaux of 1840 and in them make the whole long journey to the sea, a thousand miles away.
