The guide, taking them under his charge, led them outside the church, and then conducted them to a door leading into a small round tower, which was built at an angle of the wall. This tower, though small in size, was as high as the church, and it contained a spiral staircase of stone, which conducted up into the upper parts of the edifice. Mr. George and Rollo, however, found that they could not go up to the towers but only to what were called the galleries. But it proved in the end that they had quite enough of climbing and of walking along upon dizzy heights, in visiting these galleries, and Rollo was very willing to come down again when he had walked round the upper one of them, without ascending to the towers. There were three of these galleries. The first was an inner one; that is, it was inside the church. The two others were outside. The party was obliged to ascend to a vast height before they reached the first gallery. This gallery was a very narrow passage, barely wide enough for one person to walk in, which extended all around the choir, with a solid wall on one side, and arches through which they could look down into the church below on the other. After walking along for several hundred feet, listening to the swelling sounds of the music, which, coming from the organ and choir below, echoed grandly and solemnly among the vaults and arches above them, until they reached the centre of the curve at the head of the cross, Mr. George and Rollo stopped, and leaned over the stone parapet, and looked down. The parapet was very high and very thick, and Rollo had to climb up a little upon it before he could see over.
