rendered equally unapproachable on the north, and only the two narrow approaches on the east and west, which are capable of being easily defended, are left open for traffic. Such, above all, is the large subterranean tunnel cut--so that a man can stand upright within it--through the hard wall of lava, 6000 feet thick, by which the waters of the lake formed in the old crater of the Alban Mount were reduced to their present level and a considerable space was gained for tillage on the mountain itself.
The summits of the last offshoots of the Sabine range form natural fastnesses of the Latin plain; and the canton-strongholds there gave rise at a later period to the considerable towns of Tibur and Praeneste. Labici too, Gabii, and Nomentum in the plain between the Alban and Sabine hills and the Tiber, Rome on the Tiber, Laurentum and Lavinium on the coast, were all more or less ancient centres of Latin colonization, not to speak of many others less famous and in some cases almost forgotten.
The Latin League
All these cantons were in primitive times politically sovereign, and each of them was governed by its prince with the co-operation of the council of elders and the assembly of warriors. Nevertheless the feeling of fellowship based on community of descent and of language not only pervaded the whole of them, but manifested itself in an important religious and political institution--the perpetual league of the collective Latin cantons.
