The children passed slowly from one part of the museum to another. They examined the almonds, dates, and figs, which had been preserved so long. Some of them looked quite natural. There was a lady's toilet set that interested the girls very much. There were blackened loaves of bread and cake from the baker's oven; there were beautiful lamps and golden jewelry,--all these things made for people suddenly overtaken by death nearly two thousand years ago! It was hard to leave the museum. "But there are other things to see yet, and we cannot spend too much time in one place," Mr. Gray told them as they walked homeward. They stopped to buy some luscious yellow oranges and some ornaments of coral and lava at stands by the side of the street. That very evening ponies were brought to the hotel door, and the party started out to climb the side of Vesuvius. "I shouldn't think the people of Naples would feel safe to live so near a volcano," said Lucy. "Now that it is active again, it must make them think of the way Pompeii was destroyed. And Pompeii is several miles away, isn't it, father?" "Yes, there was no more thought of danger at that time than we feel to-night. Perhaps not so much," he added, as he looked toward his wife. She was a little pale and was feeling more timid than she liked to say. Up above them, even now, they could see the sky lighted up by the red flame. It looked as though a city must be on fire. The path wound in a roundabout way, but was always rising and was in some places very steep and rocky. "See that red stream of lava pouring down the side of the mountain," said Arthur. It was not so far away but that the children could see men at work beside it. They were scooping the lava up into vessels. It would be taken down to Naples and made into jewelry and ornaments to be sold to visitors in the city. After two miles or more of hard climbing, they reached the side of the crater. "Don't go too near. Oh, do be careful, children," cried Mrs. Gray. She was trembling as she looked at the red-hot stones flying upward in the midst of the cinders and flames. "Listen, do listen, mother. It is grand!" said Lucy, as they could now hear the roaring and grumbling, the pounding and hammering under ground. It was as though some terrible being was an angry prisoner in the volcano and was trying to free himself. Tessa clung to Mrs. Gray's skirt at first. She was frightened, too, and it was no wonder. But after a few moments both she and her kind friend had got over their fright and had begun to enjoy the strange sight. When at last Mrs. Gray said it was time to go, they all felt sorry. The drive down the mountain was quite easy. When they reached the hotel the children went straight to bed to dream of the pleasure to-morrow,--for they were to visit the buried city, Pompeii. The next day was bright and clear. Although every one felt a little tired after the excitement of the night before, they were all ready for the day's trip.
