into the brightest and purest azure; the distant mountains still retain a part of the snows of winter, but they are rapidly melting and they absolutely seem to melt reflecting the beams of the setting sun, glowing as if on fire.  And man appears emulous of Nature, for the city below is full of activity; the nearest part of the bay is covered with boats, busy multitudes crowd the strand, and at the same time may be seen a number of the arts belonging to civilised society in operation—­house-building, ship-building, rope-making, the manipulations of the smith and of the agriculturist, and not only the useful arts, but even the amusements and luxuries of a great metropolis may be witnessed from the spot in which we stand; that motley crowd is collected round a policinello, and those smaller groups that surround the stalls are employed in enjoying the favourite food and drink of the lazzaroni.

Ambrosio.—­We see not only the power and activity of man, as existing at present, and of which the highest example may be represented by the steam-boat which is now departing for Palermo, but we may likewise view scenes which carry us into the very bosom of antiquity, and, as it were, make us live with the generations of past ages.  Those small square buildings, scarcely visible in the distance, are the tombs of distinguished men amongst the early Greek colonists of the country; and those rows of houses, without roofs, which appear as if newly erecting, constitute a Roman town restored from its ashes, that remained for centuries as if it had been swept from the face of the earth.  When you study it in detail you will hardly avoid the illusion that it is a rising city; you will almost be tempted to ask where are the workmen, so perfect art the walls of the houses, so bright and uninjured the painting upon them.  Hardly anything is wanting to make this scene a magnificent epitome of all that is most worthy of admiration in Nature and art; had there been in addition to the other objects a fine river and a waterfall the epitome would, I think, have been absolutely perfect.

Phil.—­You are most unreasonable in imagining additions to a scene which it is impossible to embrace in one view, and which presents so many objects to the senses, the memory, and to the imagination; yet there is a river in the valley between Naples and Castel del Mare; you may see its silver thread and the white foam of its torrents in the distance, and if you were geologists you would find a number of sources of interest, which have not been mentioned, in the scenery surrounding us.  Somma which is before us, for instance, affords a wonderful example of a mountain formed of marine deposits, and which has been raised by subterraneous fire, and those large and singular veins which you see at the base and rising through the substance of the strata are composed of volcanic porphyry, and offer a most striking and beautiful example of the generation and structure of rocks and mineral formations.
