miles were marked upon blocks of granite or peperino, the useful invention of the popular tribune Caius Gracchus. Trees and fences by the sides were cut to admit air, and ditches, like ours, carried off the rain and residuary water from the surface. The office of _Curator Viarum_, or Road Surveyor, was bestowed upon the most illustrious members of the Senate, and the Board of Health in our days may feel some satisfaction in knowing that Pliny the Younger once held the office of Commissioner of Sewers on the Æmilian Road. Nay, the ancients deemed no office tending to public health and utility beneath them; and after his victory at Mantinea, Epaminondas was appointed Chairman of the Board of Scavengers at Thebes. We close this part of our subject, which must not expand into an archæological dissertation, with the following extract from the most eloquent and learned of the English historians who have treated of Rome. “All these cities were connected with one another and with the capital by the public highways, which, issuing from the Forum of Rome, traversed Italy, pervaded the provinces, and were terminated only by the frontiers of the empire. If we carefully trace the distance from the wall of Antoninus to Rome, and from thence to Jerusalem, it will be found that the great chain of communication, from the north-west to the south-east point of the empire, was drawn out to the length of four thousand and eighty Roman miles. The public roads were accurately divided by milestones, and ran in a direct line from one city to another, with very little respect for the obstacles either of nature or of private property. Mountains were perforated, and bold arches thrown over the broadest and most rapid streams. The middle part of the road was raised into a terrace, which commanded the adjacent country, consisted of several strata of sand, gravel, and cement, and was paved with large stones, or, in some places near the capital, with granite. Such was the solid construction of the Roman highways, whose firmness has not entirely yielded to the effect of fifteen centuries. They united the subjects of the most distant provinces by an easy and familiar intercourse; but their primary object had been to facilitate the marches of the legions; nor was any country considered as completely subdued till it had been rendered in all its parts pervious to the arms and authority of the conqueror. The advantage of receiving the earliest intelligence, and of conveying their orders with celerity, induced the emperors to establish throughout their extensive dominions the regular institution of posts. Houses were everywhere erected at the distance only of five or six miles; each of these was constantly provided with forty horses, and by the help of these relays it was easy to travel a hundred miles on a day along the Roman roads.”
