FIRST IMPRESSIONS.

To get a good idea of Rome and its topographical situation, take a carriage and drive for three hours through the principal streets; more can be learned in this way than in any other.

Start from the Piazza di Spagna; drive down the Via Babuino to the Piazza del Popolo, up to the Pincio, for a view of Rome, looking west; then along the Via Sistina, up the Quattro Fontane, to the right, down the Via Quirinale; stop in the square for the view. Proceeding to the Via Nazionale, turn up it to the left as far as the Quattro Fontane; then turn to the right past S. Maria Maggiore direct to the Lateran, from the front of which see the view eastwards; then follow the Via S. Giovanni down to the Colosseum, passing by the most perfect part. By the Via del Colosseo, Tor di Conti, Via Croce Bianca, Arco dei Pantani, Forum of Augustus, and Via Bonella, you reach the Forum, under the Capitoline Hill. Continuing by the Via Consolazione and Piazza Campitelli, follow the line of streets to the Ponte Sisto; crossing this, proceed up the Via Garibaldi to S. Peter in Montorio. Grand view of Rome and the Campagna, looking north, east, and south.

Return to the foot of the hill; turn to the left down the Lungara to S. Peter's; drive round the square; then down the Borgo Nuovo to the Castle of S. Angelo. Crossing the bridge, take the Via Coronari to the Circo Agonale; then on to the Pantheon, and by the Minerva to the Piazza di Venezia; thence up the Corso as far as the Via Condotti, up which street you return to the Piazza di Spagna, after having thus made the most interesting drive in the world.

THE TOPOGRAPHY OF ROME.

Rome commences at a point—Piazza del Popolo—and spreads out southwards like a fan, the western extremity being occupied by the Vatican, and the eastern by the Lateran; both these head-quarters of the Papacy are isolated from the rest of the city. Modern Rome occupies the valley of the Campus Martius, which was outside ancient Rome, and the hills that abut it. Rome is divided into two unequal parts by the river Tiber, which enters the line of the walls, with the Popolo on its left. For a short distance it flows southwards; then it makes a great bend to the west; then again takes a southerly direction; and at the island again turns westerly. One mile south of the Popolo Gate is the Capitoline Hill, the Arx of ancient Rome, dividing, as it were, Old from New Rome. It rises two hundred yards east of the Tiber, and from it in an eastern direction lie the other six hills, curving in a horse-shoe form round the Palatine till the Aventine abuts the river. Of the hills, the Palatine, Capitoline, Cœlian, and Aventine were only isolated mounts, the Quirinal, Viminal, and Esquiline being three spurs jutting out from the high tableland on the east side of Rome. These hills can easily be distinguished from the Tower of the Capitol; but the best way to understand them is to walk round them. Then it will be seen that they are hills indeed; and if we take into consideration that the valleys have been filled in from thirty to forty feet, and that the tops of the hills have been cut down, we may get some idea of their original height. Rome still occupies four of them; but the Aventine, Cœlian, and Palatine are left to ruins, gardens, and monks.

The original Rome was on the Palatine, and as the other hills were added they were fortified; but it was not till the time of Servius Tullius that the seven were united by one system of fortifications into one city. The plan was simple. From the Tiber a wall went to the Capitoline, and from that to the Quirinal; across the necks of the three tongues the great agger was built, then across the valleys from hill to hill till the wall again reached the river under the Aventine. The aggers across the valleys were built right up towards the city, so that the hills on either side protected the walls and gates commanding the approach. Of all the maps of Rome that have been published, the new one accompanying this work is the only one which correctly shows the line of the Servian fortifications.

THE PLAN OF OUR RAMBLES.

From the Piazza del Popolo four great lines of thoroughfare intersect the city, and passing up one of these for a few hundred yards we may count five lines. First we take the centre thoroughfare; then the two lines on its right; then the two upon its left: in this way, by dividing Rome up into five Rambles, pointing out as we go along every place of interest to the right and left, we mark out for a day's work no more than can be thoroughly done. Having thus seen the city, we take the environs outside each gate, commencing at the Porta del Popolo and working round by the east, with the exception of the Porta Appia, which leads out on to the Appian Way. As this Way presents so many points of interest, and as no visitor should think of leaving Rome without "doing it," we have made it a special Ramble for their benefit.
