Since that time there have been few steamboats on that part of the River above The Dalles. The section between The Dalles and the Cascades was joined to the tide-water section by the opening of the Government locks at the Cascades in 1896, and since that time many of the finest steamers on the River do an immense tourist business between The Dalles and Portland. It is only a question of a few years till the locks at Celilo will be completed, and then the whole vast Inland Empire, with its enormous production, will be thrown open to the sea. Then there will come on a new age of steamboat navigation, and with it the electric railroad. The steamer and the trolley car will set the whole Columbia Basin next door to tide-water. When improvements now in view by Government are completed, our River will be one of the most superb steamer courses in the world. That may truthfully be said already of the two hundred and twenty miles from The Dalles to the Ocean, as well as of the three hundred miles from Kettle Falls, Washington, to Death Rapids, B. C. The Government engineers in Senate Document, 344, February, 1890, name the amount of navigable water on the Columbia and its tributaries at 1664 miles. This may, perhaps, be an underestimation, since President Roosevelt has recently referred to it as twenty-five hundred miles, in which he probably included the lakes. Generally speaking, the rivers of the Pacific slope descend from high altitudes in comparatively short distances, and are necessarily swift. Hence we can expect no such vast extent of navigable water on them as the Mississippi and its affluents offer. Aside from the Columbia itself, the main streams, east of the Cascade Mountains offering steamboat transportation, are the Snake, Okanogan, and Kootenai, together with Lakes Pend Oreille, Chelan, Coeur d'Alene, Flathead, Okanogan, Kootenai, Arrow, Christina, and Slocan. On the west side are the Willamette, Cowlitz, and Lewis rivers. It would fill a volume to narrate even a tithe of the thrilling tales of daring and tragedy which gather around the subject of boating in all its forms on the Columbia. One of the most remarkable steamboat journeys was that elsewhere described in this work, under command of Captain F. P. Armstrong, of the _North Star_, from Jennings, Montana, on the Kootenai to Canal Flats and thence through the canal to Lake Columbia. With that should be coupled as equally daring and more difficult, the trip down Snake River, from the Seven Devils to Lewiston, in a steamer piloted by Captain W. P. Gray.
