"This is the well," said Philippe; "the well that they were digging when they first came upon the ruins."

The sides of the well were of solid lava, smooth and hard, just as they had been left by the workmen in digging down.

The light which came down through the well shone upon a sort of platform, which, as well as the walls around it, was covered with moss and other green plants, which had been induced to vegetate there by the rain and the sunlight that had come down through the well. Mrs. Gray gathered some of these plants, and put them into her book.

The party then went on down another flight of steps, which led into a series of dark, vaulted chambers, all hewn out of the rock. By holding the candles up to the sides of these chambers, the party could see here and there the remains of old arches, columns, and walls, which had been buried up in the lava, but were now partially disinterred.

These remains were part of an ancient theatre; and after passing through several gloomy passages, the party came to a large chamber, where the whole front of the stage had been brought to view. Before it, in a range, were the seats for the musicians. On each side there was a massive pedestal. The guide said that there were two bronze statues on these pedestals when the place was first excavated, but that they had been taken away, and were now deposited in the museum at Naples.

"We shall see them there, I suppose," said Mr. George, "when we go to visit the museum."

"I shall take great interest in seeing them," said Mrs. Gray.

In some places the old pavement of the theatre had been laid bare, and was plainly to be seen by holding the candles down close to the ground. In other places the painting on the walls had been found, with the colors quite fresh.

"These must be places that the hot lava did not come to," said Rollo.

"I suppose so," said Mr. George.
