We returned, Mr R---- D---- and I, from our visit to Vesuvius, half dead with fatigue from having had little or no rest the whole night, about three o'clock to Naples. We left Naples in a _calèche_ yesterday after breakfast and drove to Portici. Portici, Resina, and Torre del Greco are beautiful little towns on the sea-shore of the bay of Naples or rather they may be termed a continuation of the city, as they are close together in succession, and the interval filled up with villas. The distance from the gates of Naples to Portici is three miles. The road runs through the court yard of the Royal Palace at Portici which has a large archway at its entrance and sortie. We proceeded to Resina and alighted in order to descend under ground to Herculaneum, Resina being built on the spot where Herculaneum stood. There are always guides on this road on the look out for travellers; one addressed us, and conducted us to a house where we alighted and entered. Our guide then prepared a flambeau, and having unlocked and lifted up a trap door invited us to descend. A winding _rampe_ under ground leads to Herculaneum. We discovered a large theatre with its proscenium, seats, corridors, vomitories, etc., and we were enabled, having two lighted torches with us, to read the inscriptions. Some statues that were found here have been removed to the Museum at Portici. This is the only part of Herculaneum that has been excavated; for if any further excavations were attempted, the whole town of Resina, which is built over it, would fall in. Herculaneum no doubt contains many things of value, but it would be rather too desperate a stake to expose the town of Resina to certain ruin, for the sake of what _might_ be found. At Pompeii the case is very different, there being nothing built over its site.
