All the great rivers ofCentral Russia have arrived at a state of mature adjustment to the land,having drained their ancient lakes and established their individuality asriver systems. They carry an enormous volume of water, although com-.

The Volga.—The Volga is the first of Russian rivers; it is the longestand has the largest volume of water in all Europe. Rising in a peat mossthe little stream flows through a series of lakes, and on leaving Lake Volgoit is a considerable river with a volume of from no to 1,320 cubic feet persecond, according to the season. Its first important tributary is theSelizharovka, which flows from the lake of Seliger, and at the confluenceof these two rivers, which are of almost equal volume, the true course ofthe Volga may be said to commence. The tributaries on the left bankflow from the low watersheds which separate the Volga from the riversystems of the Baltic and the White Seas. At Nizhnii-Novgorod it uniteswith the Oka, a river of equal size,
