of the Territory, has its mouth near latitude 49^. McGil- 

 livray's or Flat Bow River rises and has its mouth in British 

 Columbia, but two hundred miles of its course are in Washing- 

 ton. Among the notev^^orihy tributaries of the Snake are the 

 Salmon, the Clearwater (styled Kooskooske on some mnps), 

 and the Pelouse. The distance from the mouth of the Snake 

 to that of Clark's river is three hundred miles, in which 

 distance no stream worthy of note save the Spokane, and 

 that not a large river, enters the Columbia from the east- 

 The Okinagan, an outlet of Lake Okinagan, runs into the 

 Columbia from British America. The main streams ruiining 

 from the east slope of the Cascade Mountains to the Columbia 

 are the Yakima and Wenatchee, whose valleys are so far 

 chiefly notable for their auriferous deposits and hostile Indians. 

 The Klickatat River, fed by the snow^s of Mount Adams, runs 

 southward, and has its mouth near the Dalles. West of the 

 Cascade Mountains, the Cathlapootl and Cowlitz Rivers are the 

 only streams of note entering the Columbia. The Xisqually, 

 Puyallup, White, Green, Cedar, Snoqualmie, Squamish, Sto- 

 lukwamish, and Skaget Rivers pour down immense bodies of 

 water from the west slopes of the Cascade range to Puget 

 Sound and the Gulf of Georgia. The Skaget River rises north- 

 east of Mount Baker, and, after running round the east, south, 

 and west bases of the mountain, becomes a very large rivei', and 

 might be navigated by large vessels, were it not for a bar at its 

 mouth, and rafts of driftwood which have become fastened 

 between its banks. None of the other streams flowing into 

 Puget Sound are navigable, unless very near their mouths in 

 tidewater. The rivers running westward to the Pacific are 

 the Willopah, which has its mouth in Shoal water Bay ; the 

 Chehalis, which falls into Gray's Harbor; the Quiniult, and 

 some other streams near Cape Flattery, of wldch little is 

 known. The Chehalis has been navigated by schooners for 

 twenty-five miles from its mouth. — Washington possesses a 

 great multitude of harbors, perhaps more than any other 

 country of equal extent on the globe. Puget Sound, which
