Show Geographers claim that""there"aTe twenty-five rivers on the globe which have a total length each of over 1,000 miles. Of these, two, the Mississippi from the sonrce ef the Missouri In the Rocky monntains to the Eads jetties, and the Amazon from the sonrce of the EenI to the isle of Marajo, are over 4,000 miles in length. To be exact, the former is 4,300 and the latter 4,029 miles from the ssnree to the place where their waters are mingled with those of the ocean. Four claim a total length of over 3,000 and under 4,000. They are the Yenisei in Asia, length 3,580; the Kiang, Asia, length 8,900; the Nile, Africa, 3,240; and the Hoang-ho, Asia-which Asia-which is 3,040 miles. Seven streams on the globe are under 3,000 and over 2,000 miles in length, Volga in . Russia and the Atnoor in Asia each . being 2,500 miles in length; two are 2,800 miles long, the Mackenzie in British America and the Platte in Sonth America. The Rio Bravo in North America, the Rio Maderia in South, America, and the Niger la Africa are each '2,300 miles from 6ndto end. The Arkansas river just comes inside of this 2,000 mile limit. Ten of the great rivers of the world are OAer 1,000 and nnder 2,000 miles' in length. Three of these are In North America, the Red river 1,520, Ohio 1,480, and, the St. Lawrence 1,450. South America has only three in this list, the Rio JJegro 1,650, Orinoco 1,600, and the Cr rignay 1,100 miles. Asia has three In the same list, the Euphrates 1,900 miles, and the Tigris and the Ganges, each of which is about 1,300 miles. In the group of great rivers, the St. Lawrence is the most remarkable. It constitutes by far the largest body of fresh water in the werld. If we include the Great Lakes and the tributary rivers with the St. Lawrence system, as they .cover -about 73,000 square miles, the aggregate represents-not less than 9,000 miles of water. The nnthinkaule size of this mass may be better comprehended when eve consider the figures of Professor Pro-fessor Cyrus C. Dinwiddle, who says that it would take over forty years for this entire mass to pour over Niagara 'at the computed rate of 1,000,000 cubic feet per second. |
