One of these boys had a censer in his hands, and another had a little bell; and as they came along you could see the censer swinging in the air, and the volumes of fragrant smoke rising from it, and you could hear the tinkling of the little bell. The priest advanced to the altar before which the audience were sitting, and there, while the censer was waving and the smoke was ascending, he performed various ceremonies which Rollo could not at all understand, but which seemed to interest the congregation very much, for they bowed continually, and crossed themselves, and seemed impressed with a very deep solemnity. Presently, when the ceremony was completed, the procession returned into the choir, the priest at the head of it, just as it came. When the procession had passed away, Mr. George made a sign for Rollo to follow him, and then walked along out through the gate where the woman was sitting with the holy water. She held out the brush to Mr. George and Rollo as they passed, but they did not take it. "What ridiculous mummeries!" said Rollo, in a low tone, as soon as they had got out of the hearing of the congregation. "Yes," said Mr. George, "they seem so to us; but I have a certain respect for all those ceremonies, since they are meant to be the worship of God." "I thought it was the worship of images," said Rollo. "Did not you see the images?" "Yes," said Mr. George, "I saw them; and perhaps we can make it out that those rites are, in reality, the worship of images; but they are not _meant_ for that. They are _meant_ for the worship of God." CHAPTER III. THE GALLERIES. "I want to get up upon the towers," said Rollo, "if we can." "Yes," said Mr. George, "but I want first to go and see the tomb of the three kings." "What is that?" asked Rollo.
