"The road," Bushnell says, "is that physical sign or symbol by which you will best understand any age or people. If they have no roads, they are savages; for the road is the creation of man and a type of civilized society. If you wish to know whether society is stagnant, learning scholastic, religion a dead formality, you may learn something by going into universities and libraries, something also by the work that is doing on cathedrals and churches or in them, but quite as much by looking at the roads; for if there is any motion in society, the road, which is the symbol of motion, will indicate the fact."

As roads are the symbols of progress, so, according to the philosophy of Carlyle, they should only be used by working and progressive people, as he asserts that the public highways ought not to be occupied by people demonstrating that motion is impossible. Hence, when we trace back the history of the race to the dawn of civilization, we find that the first sponsors of art and science, commerce and manufacture, education and government, were the builders and supporters of public highways.

The two most ancient civilizations situated in the valleys of the Nile and the Euphrates were connected by a commercial and military highway leading from Babylon to Memphis, along which passed the war chariots and the armies of the great chieftains and military kings of ancient days, and over which were carried the gems, the gold, the spices, the ivories, the textile fabrics, and all the curious and unrivalled productions of the luxurious Orient. On the line of this roadway arose Nineveh, Palmyra, Damascus, Tyre, Antioch, and other great commercial cities.

On the southern shores of the Mediterranean the Carthaginians built up and consolidated an empire so prominent in military and naval achievements and in the arts and industries of civilized life, that for four hundred years it was able to hold its own against the preponderance of Greece and Rome; and as might have been expected, they were systematic and scientific road-makers from whom the Romans learned the art of road-building.

The Romans were apt scholars, and possessed a wonderful capacity not only to utilize prior inventions but also to develop them. They were beyond question the most successful and masterful road-builders in the ancient world; and the perfection of their highways was one of the most potent causes of their superiority in progress and civilization. When they conquered a province they not only annexed it politically, by imposing on its people their laws and system of government, but they annexed it socially and commercially, by the construction of good roads from its chief places to one or more of the great roadways which brought them in easy and direct communication with the metropolis of the Roman world. And when their territory reached from the remote east to the farthest west, and a hundred millions of people acknowledged their military and political supremacy, their capital city was in the centre of such a network of highways that it was then a common saying, "All roads lead to Rome." From the forum of Rome a broad and magnificent highway ran out towards every province of the empire. It was terraced up with sand, gravel, and cement, and covered with stones and granite, and followed in a direct line without regard to the configuration of the country, passing over or under mountains and across streams and lakes, on arches of solid masonry. The military roads were under the pretors, and were called pretorian roads; and the public roads for travel and commercial traffic were under the consuls, and were called consular roads. These roads were kept entirely distinct; the pretorian roads were used for the marching of armies and the transportation of military supplies, and the consular roads were used for traffic and general travel. They were frequently laid out alongside of each other from place to place, very much as railroads and highways are now found side by side. The consular roads were generally twelve feet wide in the travelled pathway, with a raised footway on the side; but sometimes the footway was in the middle of the road, with a carriage-way on each side of it. The military roads were generally sixty feet wide, with an elevated centre, twenty feet wide, and slopes upon either side, also twenty feet wide. Stirrups were not then invented, and mounting stones or blocks were necessary accommodations; and hence the lines of the roads were studded with mounting-blocks and also with milestones. Some of these roads could be travelled to the north and eastward two thousand miles; and they were kept in such good repair that a traveller thereon, by using relays of horses, which were kept on the road, could easily make a hundred miles a day. Far as the eye could see stretched those symbols of her all-conquering and all-attaining influence, which made the most distant provinces a part of her dominions, and connected them with her imperial capital by imperial highways.

The Romans not only had great public highways, but they possessed a complete and systematic network of cross-roads, which connected villages, and brought into communication therewith cultivated farms and prosperous homesteads. In Italy alone it is estimated that they had about fourteen thousand miles of good roads. Their laws relating to the construction and maintenance of highways were founded in reason and a just conception of the uses and objects of public ways; and they are the basis of modern highway legislation. By their law the roads were for the public use and convenience, and their emperors, consuls, and other public officials were their conservators. They were built at the public expense, under the supervision of professional engineers and surveyors, and kept in repair by the districts and provinces through which they passed.

But during the dark ages, when arts were lost, when popular learning disappeared or found shelter only in cloisters and convents, when commercial intercourse between nations vanished, and when civilization itself lay fallen and inert, these magnificent Roman roads were unused and left to the destructive agencies of time and the elements of Nature. Rains and floods washed away and inundated their embankments; forests and rank vegetation overgrew and concealed them; winds covered them with dust and heaps of sand; and little by little in the process of ages their hard surfaces and massive foundations were somewhat broken and caused to partially decay. That their remains still exist in every part of the world which ever bore up the Roman legions is conclusive evidence that they were built by master workmen who realized that they were responsible to posterity and to the eternal powers.
