The two men were standing in the doorway of the artist's home on the Monday after the carnival. Tessa had not forgotten to tell her father that Mr. Gray wished to see him. "We shall be gone only a few days. We are going to take a short trip to Naples," the artist went on. "But Lucy wishes Tessa's company very much, and I think your little girl would enjoy it. What do you say?" The peasant was greatly pleased. His face beamed, as he replied: "You are a good friend to us, Mr. Gray. We can never forget it. What shall we do when you go back to America?" "That time will not come for two years yet. In the meanwhile, talk with your wife. If she is willing, bring Tessa here Tuesday morning. We shall leave on the afternoon of that day." You can imagine how excited our little Italian cousin was, when she found herself riding on a train for the first time. The cars were much smaller than we use here in America. It would have seemed odd to you to have the conductor (or the guard, as he is called in Europe) lock the doors when the train is about to start. "We are prisoners," laughed Lucy. "We can't get out now, even if we should wish to do so ever so much." She was now able to chatter in Italian almost as fast as in her own English tongue. "That is because of her acquaintance with Tessa and her brother," Mr. Gray told his wife. "Those children surprise me by the good Italian they speak, when they have had so little schooling. Although their parents are peasants, they are gentle people in their nature. And that is more than learning, after all." The children were delighted with Naples. The city rests on the shore of what some people consider the most beautiful bay in the world. Everything about it looked clean and orderly, although a few years ago it was a very filthy city. No one seemed in a hurry. Even the beggars, who came to meet the children with hands stretched out for alms, looked lazy and happy. There were beautiful gardens to walk in, and fine buildings to visit, besides rowing and sailing on the blue waters of the bay. There was plenty to see, but best of all was the morning the children spent in the museum, where there was a large collection of curiosities. "They all came from the buried city," Mr. Gray explained. "Think of it, children! These beautiful ornaments, vases, and bronzes, were hidden under the ashes for eighteen hundred years. One day it was discovered by some workman that he was digging into the ruins of a building. Others came to help him, and by and by they found a city beneath the ashes and soil which had formed above it." "You are going to take us to see the city before we go back to Rome, aren't you, father?" asked Arthur. "Certainly; I would not have you miss the sight for a good deal. But does Tessa know its name?" "O yes, it is Pompeii. I have heard much about it," the little Italian answered. "It is another of the wonderful sights in my country of which I am so proud."
