The River, on its way fiom Lake Erie to LakeOntario, makes a total descent of 330 feet; about one-halfof this descent is over a precipice, down which the waters rushwith such tremendous force, that they are constantly weaiingaway the rocks beneath ; therefore, Niagara Falls are gradu-ally receding toward Lake Erie. 27. Some Rivers of Mountainous Districts, as in Califor-nia, have worn long, narrow channels in the rocks, calledCanons {kanyitns). A remarkable caiion of the ColoradoRiver is in Utah and Arizona. Its length is 300 mUes, andthe rocks stand perpenchcularly above the water in the gorge,to heights varying from 3,000 to 6,000 Passages worn ihrough the Rocks on the Southern Coast of Norway. 28. A River System is composed of a river and its tribu-taries ; thus resembhng a great vine with its branches spreadin all diiections. 29. A River Banin comprises all the land that is drainedby a river and its tributaries. In the lowest part of the val-ley flows the princijaal stream. 30. The Rasin of the Amazon covers an area of more than2,000,000 square miles; that of the Mississippi, about 1,000,000square miles. 31. A Watershed is the ridge of land which surrounds ariver basin and casts the water in different directions. 32. The Watershed of Rivers flowing dotrti opposite Sidesof a Mountain. Range, is that part of the range which is ele-vated above the sources of those streams. 33. A River Bed is the gi-ou:d over which the water channel is the deepest part of a river. The
