Mr. George looked up where Rollo had pointed, and there he saw a gallery at a great elevation above them, with a choir of singers in front, and an enormous organ towering to a great height towards the vaulted roof behind. The choir was separated from the body of the church by ranges of columns above, and by richly-carved and ornamental screens and railings below. The ceilings were beautifully painted in fresco, and here and there were to be seen lofty windows of stained glass, antique and venerable in form, and indescribably rich and gorgeous in coloring. After gazing about upon this scene for a few minutes with great admiration and awe, Rollo called his uncle's attention to a discovery which he suddenly made. "See," said he; "uncle George, there is a congregation." So saying, Rollo pointed across the choir to a sort of gateway, which was opposite to the side on which they came in, and where, through the spaces which opened between the great columns that intervened, a congregation were seen assembled. They were in a chapel which was situated in that part of the church. The chapel itself was full, and a great many persons were seated in the various spaces rear. Mr. George and Rollo walked across the choir, and joined this congregation by taking a position near a pillar, where they could see what was going on. At a corner near a little gateway in a railing, where the people appeared to come in, there was a woman sitting with a brush in her hand. The brush was wet with holy water. The people, as they came in,--for a few came in after Rollo and Mr. George arrived at the place,--touched their fingers to this brush, to wet them, and then crossed themselves with the holy water. At the altar was a priest dressed in splendid pontificals. He was standing with his back to the people. There was a great number of immensely tall candlesticks on each side of him, and a great many other glittering emblems. The priest was dressed in garments richly embroidered with gold. There was a boy behind him dressed also in a very singular manner. The priest and the boy went through with a great variety of performances before the altar, none of which Rollo could at all understand. From time to time the boy would ring a little bell, and the organ and the choir of singers in the lofty gallery would begin to play and sing; and then, after a short time, the music would cease, and the priest and the boy would go on with their performances as before. Presently Rollo heard a sound of marching along the paved floor, and looking into the choir whence the sounds proceeded, he saw a procession formed of boys, with a priest, bearing some glittering sacred utensils of silver in his hands, at the head of them. The boys were all dressed alike. The dress consisted of a long crimson robe with a white frock over it, which came down below the waist, and a crimson cape over the frock, which covered the shoulders. Thus they were red above and below, and white in the middle.
