Of these the Eleutherus is the most important.

"It is a considerable stream even in summer, and in the rainy season it is a barrier to intercourse, caravans sometimes remaining encamped on its banks for several weeks, unable to cross."[121] The soil of the plain is shallow, the rock lying always near the surface; the streams are allowed to run to waste and form marshes, which breed malaria; a scanty population scarcely attempts more than the rudest and most inefficient cultivation; and the consequence is that the tract at present is almost a desert.

Nature, however, shows its capabilities by covering it in the spring-time from end to end with a "carpet of flowers."[122] From the edges of the plains, and sometimes from the very shore of the sea, rise up chalky slopes or steep rounded hills, partly left to nature and covered with trees and shrubs, partly at the present day cultivated and studded with villages.

The hilly region forms generally an intermediate tract between the high mountains and the plains already described; but, not unfrequently, it commences at the water's edge, and fills with its undulations the entire space, leaving not even a strip of lowland.

This is especially the case in the central region between Berytus and Arka, opposite the highest portion of the Lebanon; and again in the north between Cape Possidi and Jebili, opposite the more northern part of Bargylus.
