retaining the wild freedom of their tribe, and the possession of the lands they have seized, they have opposed the advance of the Roman legions into the uncultivated districts they call their own; they have even succeeded in destroying the military forces which guarded the Rhine, and have with difficulty been restrained from crossing the great river by a strong line of forts and castles, of which the remains astonish the traveller of the present day, as, with Murray's Guide-Book in his hand, he gazes upon their ruins between Bingen and Aix-la-Chapelle. Repelled by these barriers, they cluster thicker than ever in the woods and valleys, to which the Romans have no means of penetrating. Southern Gaul submits, and becomes a civilized outpost of the central power; but far up in the wild regions of the north, and even to the eastward of the Gulfs of Bothnia and Finland, the assemblage goes on. Scandinavia itself becomes over-crowded by the perpetual arrival of thousands of these armed and expatriated families, and sends her teeming populations to the east and south. But all these incidents, I must remind you, are occurring in darkness. We only know that the desert is becoming peopled with crowded millions, and that among them all there floats a confused notion of the greatness of the Roman power, the wealth of the cities and plains of Italy; and that, clustering in thicker swarms on the confines of civil government, the watchful eyes of unnumbered savage warriors are fixed on the territories lying rich and beautiful within the protection of the Roman name. So the whole Roman boundary gets gradually surrounded by barbaric hosts. Their trampings may be heard as they marshal their myriads and skirt the upper boundaries of Thrace; but as yet no actual conflict has occurred. A commotion may become observable among some of the farthest distant of the half intimidated of the German tribes; or an enterprising Roman settler beyond the frontier, or travelling merchant, who has penetrated to the neighbourhood of the Baltic, may bring back amazing reports of the fresh accumulations of unknown hordes of strange and threatening aspect; but the luxurious public in Rome receive them merely as interesting anecdotes to amuse their leisure or gratify their curiosity: they have no apprehension of what may be the result of those multitudinous arrivals. They do not foresee the gradual drawing closer to their outward defences--the struggle to get within their guarded lines--the fight that is surely coming between a sated, dull, degraded civilization on the one side, and a hungry, bold, ambitious savagery on the other. They trust every thing to the dignity of the Eternal City, and the watchfulness of the Emperor: for to this, his one idea of irresistible power equally for good or evil, the heart of the Roman was sure to turn. And for the eleven years of the reigns of Vespasian and Titus, the Roman did not appeal for protection against a foreign enemy in vain.
