The gaudily painted stalls of the iced-water and lemonade dealers give warmth of color to the streets. There are several grades in the calling of _acquaiolo_ (water-seller). The lowest member of the craft is the peripatetic _acquaiolo_, who goes about furnished simply with a barrel of iced water strapped on his back, and a basket of lemons slung to his waist, and dispenses drinks at two centesimi a tumbler. It was thought that the completion of the Serino aqueduct, which provides the whole of Naples with excellent water at the numerous public fountains, would do away with the time-honored water-seller; but it seems that the poorer classes cannot do without a flavoring of some sort, and so this humble fraternity continue as a picturesque adjunct of the streets. These are only a few of the more striking objects of interest which the observer will not fail to notice in his walks through the city. But we must leave this fascinating occupation and turn to some of the regulation sights of Naples. Though, in proportion to its size, Naples contains fewer sights and specific objects of interest than any other city in Italy, there are still a few public buildings and churches which the tourist should not neglect. There are quite half-a-dozen churches out of the twenty-five or thirty noticed by the guide-books which fully repay the trouble of visiting them. The Cathedral is in the old part of the town. Its chief interest lies in the gorgeous Chapel of St. Januarius, the patron saint of Naples. In a silver shrine under the richly decorated altar is the famous phial containing the coagulated blood of the saint. This chapel was built at the beginning of the seventeenth century, in fulfilment of a vow by the grateful populace in honor of the saint who had saved their city "from the fire of Vesuvius by the intercession of his precious blood." St. Januarius is held in the highest veneration by the lower classes of Naples, with whom the liquefaction ceremony, which takes place twice a year, is an article of faith in which they place the most implicit reliance. The history of the holy man is too well known to need repetition here. The numerous miracles attributed to him, and the legends which have grown round his name, would make no inconsiderable addition to the hagiological literature of Italy.
