uire, with anxious curiosity, whether
Europe is still threatened with a repetition of those calamities, which
formerly oppressed the arms and institutions of Rome. Perhaps the same
reflections will illustrate the fall of that mighty empire, and explain
the probable causes of our actual security.

I. The Romans were ignorant of the extent of their danger, and the
number of their enemies. Beyond the Rhine and Danube, the Northern
countries of Europe and Asia were filled with innumerable tribes of
hunters and shepherds, poor, voracious, and turbulent; bold in arms,
and impatient to ravish the fruits of industry. The Barbarian world was
agitated by the rapid impulse of war; and the peace of Gaul or Italy was
shaken by the distant revolutions of China. The Huns, who fled before a
victorious enemy, directed their march towards the West; and the torrent
was swelled by the gradual accession of captives and allies. The flying
tribes who yielded to the Huns assumed in _their_ turn the spirit of
conquest; the endless column of Barbarians pressed on the Roman empire
with accumulated weight; and, if the foremost were destroyed, the vacant
space was instantly replenished by new assailants. Such formidable
emigrations can no longer issue from the North; and the long repose,
which has been imputed to the decrease of population, is the happy
consequence of the progress of arts and agriculture. Instead of some
rude villages, thinly scattered among its woods and morasses, Germany
now produces a list of two thousand three hundred walled towns:
the Christian kingdoms of Denmark, Sweden, and Poland, have been
successively established; and the Hanse merchants, with the Teutonic
knights, have extended their colonies along the coast of the Baltic,
as far as the Gulf of Finland. From the Gulf of Finland to the Eastern
Ocean, Russia now assumes the form of a powerful and civilized empire.
The plough, the loom, and the forge, are introduced on the banks of the
Volga, the Oby, and the Lena; and the fiercest of the Tartar hordes have
been taught to tremble and obey. The reign of independent Barbarism is
now contracted to a narrow span; and the remnant of Calmucks or Uzbecks,
whose forces may be almost numbered, cannot seriously excite the
apprehensions of the great republic of Europe. Yet this apparent
security should not tempt us to forget, that new enemies, and unknown
dangers, may _possibly_ arise from some obscure people, scarcely
visible in the
