Saratov occupies the eastern part of the great central plateau of Russia, which slopes gently towards the south until it merges imperceptibly into the steppe region; its eastern slope, deeply cut into by ravines, falls abruptly towards the Volga. As the higher parts of the plateau range from 700 to 900 ft. above the sea, while the Volga flows at an elevation of only 20 ft. ”
