The tract lying to the north-west contains the states of Bikanir, Jaisalmer and Jodhpur.
The site is a level oblong tract extending along the Hudson for 7 m.
The tract adjoining this long line of lagoons is, like the basin of the Po, a broad expanse of perfectly level alluvial plain, extending from the Adige eastwards to the Carnic Alps, where they approach close to the Adriatic between Aquileia and Trieste, and northwards to the foot of the great chain, which here sweeps round in a semicircle from the neighborhood of Vicenza to that of Aquileia.
Parma, one of the finest cities of northern Italy, lies in a fertile tract of the Lombard plain, within view of the Alps and sheltered by the Apennines, 170 ft.
While the rugged and mountainous district of Calabria, extending nearly due south for a distance of more than 150 m., thus derives its character and configuration almost wholly from the range of the Apennines, the long spur-like promontory which projects towards the east to Brindisi and Otranto is merely a continuation of the low tract of Apulia, with a dry calcareous soil of Tertiary origin.
