ention to reinstate it. This gate formed three entrances. The two
side ways were probably intended for pedestrians; the one in the middle
was closed by means of a portcullis sliding in a groove, still visible,
but covered with stucco. As the portcullis, in descending, would have,
thrown down this coating, we must infer that at the time of the eruption
it had not been in use for a long while, Pompeii having ceased to be a
fortified place.
The Herculaneum gate was not masked inside, so that the archers,
standing upon the terraces that covered the side entrances, could fire
upon the enemy even after the portcullis had been carried. We know that
one of the stratagems of the besieged consisted in allowing the enemy to
push in, and then suddenly shutting down upon them the formidable
_cataracta_ suspended by iron chains. They then slaughtered the poor
wretches indiscriminately and covered themselves with glory.
Having passed the gate, we find ourselves on one of those fine paved
roads which, starting at Rome in all directions, have everywhere left
very visible traces, and in many places still serve for traffic. The
Greeks had gracefulness, the Romans grandeur. Nothing shows this more
strikingly than their magnificent highways that pierce mountains, fill
up ravines, level the plains, cross the marshes, bestride rivers, and
even valleys, and stretched thus from the Tiber to the Euphrates. In
order to construct them, they first traced two parallel furrows, from
between which they removed all the loose earth, which they replaced with
selected materials, strongly packed, pressed, and pounded down. Upon
this foundation (the _pavimentum_) was placed a layer of rough stone
(_statumen_), then a filling-in of gravel and lime (the _rudus_), and,
finally, a third bed of chalk, brick, lime, clay, and sand, kneaded and
pounded in together into a solid crust. This was the nucleus. Last of
all, they placed above it those large rough blocks of lava which you
will find everywhere in the environs of Naples. As before remarked,
these roads have served for twenty centuries, and they are good yet.

The Herculaneum road formed a delightful promenade at the gates of
Pompeii; a street lined with trees and villas, like the Champs Elysees
at Paris, and descending from the city to the country between two rows
of jaunty monuments prettily-adorned, niches, kiosks, and gay pavilions,
from which the view
