The first consists in the parallelism in the course of its rivers, as the Danube and the Theiss, the Drave and the Save, the Waag with the Neutra and the Gran, &c. The second is the direction of the rivers, which converge towards the middle of the country, and are collected either mediately or immediately by the Danube.
The principal tributaries of the Danube in Hungary, of which some are amongst the largest rivers in Europe, are, on the right, the Raab, Drave and Save, and, on the left, the Waag, Neutra, Gran, Eipel, Theiss (the principal affluent, which receives numerous tributaries), Temes and Cserna.
The cavalry established contact on the 15th in the neighbourhood of Tobitschau and Rochetinitz (action of Tobitschau, July 15th), and the Austrians finding their intention discovered, and their men too demoralized by fear of the breechloader to risk a fresh battle, withdrew their troops and endeavoured to carry out their concentration by a wide circuit down the valley of the Waag and through Pressburg.
They extend between the rivers Waag, Arva, Dunajec and Poprad, and form a sharply defined and isolated group, rising abruptly like a gigantic wall to an altitude of over 8400 ft.
(c) The central groups or the High Carpathians extend from the confluence of the rivers Arva and Waag to the river Poprad, and include the highest group of the Carpathian system.
