The port of Cette, on this coast, is located nearan inlet between two sections of a barrier beach, where a sufficientdepth of water is maintained with difficulty. Marseilles is the one naturalport on the southern coast of France, and owes its preeminence to a de-pressed coast and to a shore line so shaped as to furnish protection 32 THE NATURAL ENVIRONMENT t> -0- Ughlhouscs ^-^— Brcakvatcn 1^ -« Direction of Drift.

Harbor works have increased the size andsafety of the port until it has become one of the chief harbors on the entire Mediterranean coast to the Rhone valley,which is the natural line oftravel inland, is gained byconstructing railroads fromMarseilles to join the riverabove its delta. In the Adriatic Sea similarconditions prevail. Triesteand Fiume are the termina-tions of important steamshiplines, but the sand-fringedItalian shore furnishes nogood harbors, and the greatPo River, the natural line ofentrance to Italy, is rendereduseless by a rapidly growingand constantly shifting delta. The old port of Adria, which gavethe name to the Adriatic Sea, is now 14 miles inland. Two places on the west coast of theUnited States, Puget Sound and SanFrancisco Bay, possess natural harborsites of high grade.
