horizon, are more picturesque. But these advantages are more than balanced by 

 a fertile alluvial soil being only met with in the tertiary hills to the south of the 

 river, whilst the cultivable area extending along the granitic heights commanding 

 the left bank is very small in extent. The Danube, as appears from Fig. 19, forms a 

 well-defined geological boundary, separating the crystalline rocks of the north 

 from the tertiary and recent formations of the south. 



lù'cnis (6,114 inhabitants), the only town of importance on the left bank of the 

 Danube, occupies a site where both banks are of tertiary formation. Linz (30,838 

 inhabitants) is very favourably situated near the mouth of the Traun, and at the

Vienna* offers one of the most striking instances of the influence exercised by 

 geographical position upon political destinies. Vindobona, in the time of the 

 liomans, was the head-quarters of a legion and of a flotilla, but it had no more 

 importance than Lauriacum (Lorch), at the mouth of the Enns, for the great 

 military station of Pannonia was naturally established art the northern outlet of 



* Vienna, in 1869, had 632,494 inhabitants, or, with its 18 suhurhs, 833,855. In 1877 the popula- 

 tion was estimated at 1,050,000. The principal suburbs are Hernals, Funfhaus, Rudolfsheim, Ottakring, 

 jMeidling, Gaudenzhaus, &c.
