These cities and many villages were wiped out in a single day, and a large region of country was depopulated. After the catastrophe, some of the inhabitants returned, and made excavations for recovering their valuables. Some robbers also crept into the city. The Emperor Titus entertained the idea of cleaning and restoring the city, and sent two senators to examine the ground; but the magnitude of the work frightened the government, and the restoration was never undertaken. In time Pompeii became almost forgotten, and its site was lost. For more than a dozen centuries the locality where Pompeii had stood was unknown. In 1748, under the reign of Charles III., when the discovery of Herculaneum had attracted the attention of the world to that locality, some vine-dressers struck upon some old walls, and unearthed a few statues. The king ordered some excavations to be made in the vicinity; but it was not until eight years later that any one supposed that they were exhuming Pompeii. Since that time the work of excavation has gone on with a great many intervals of inactivity. Whenever the government makes an appropriation, or some crowned head or other wealthy personage makes an addition to the Pompeian fund, the work is prosecuted; but as soon as the money is expended the work stops. It is now more than a hundred years since the excavation began, and the third part of the city is not yet uncovered. Since 1860, the whole system of work and management has been reformed, and moralized, as it were. All the guides and door-keepers are under the control of the government. The visitor pays two francs at the gate, and is guided about the city by a man clad in uniform. Notices are posted in all the modern languages, telling visitors not to give money to the guides under any pretence whatever, and forbidding the guides to receive the money. This is all very well as far as it goes; but human ingenuity is able to get around the rule. [Sidenote: DODGING A REGULATION.] We had a guide who spoke French fluently, and was a very polite and agreeable fellow. He took pains to call our attention to one of the signs, and assured us that he could not receive a penny under any circumstances. But at almost every step he had photographs to sell. Whenever we found anything particularly interesting, out from his pocket came a package of photographs, and of course we purchased. By the time we had finished our journey, we had bought photographs enough to stock a small store; and the profit on the transaction was probably six times as much as the guide would have wrung from us had the old system been in vogue. It is very evident that the government winks at this transaction; otherwise the guides would not be allowed to sell photographs or anything else.
