The aisles, as may be seen by the plan, are not so wide as the nave and choir. There is another thing also to be noted respecting them that is quite important, though it cannot be seen in the plan--and that is, that they are not so high, the roof being carried up to a greater height in the centre of the church--that is, over the nave and choir--than it is at the sides over the aisles. Thus these ranges of columns not only divide different portions of the floor from each other below, but they also separate roofs of different altitudes above. But let us return to Mr. George and Rollo. We left them in the Poet's Corner, at A. As they looked through the columns near them, they saw the congregation filling the whole central part of the church. "Let us go up and find a seat," said Mr. George. So Mr. George led the way between the columns into the south transept. You can see exactly where they went by looking at the plan. This transept was filled with settees, which were placed in two ranges, with a passage way in the middle between them. The front settees were filled with people, and over the heads of them Mr. George could see that there were other ranges of settees in the north transept and the choir. There were various desks, and pulpits, and oratories, and carved stalls, and canopies to be seen in the interior, and many separate compartments of seats, some enclosed by ancient carved oak railings, and others with large worsted ropes, of a dark-brown color, drawn across the entrance to them. Above, clusters of columns and tall pinnacles, rising from canopies and screens, ascended high into the air; and between and beyond them were to be seen gorgeous windows of colored glass, of the most antique and timeworn appearance, and of enormous size. Over the heads, too, of the congregation of living worshippers, and mingled with them in various recesses and corners, were to be seen numberless groups and statues of marble. These statues were, in fact, so mingled with the worshippers, that, in surveying the assemblage, it seemed, in some cases, difficult for a moment to distinguish the living forms of the real men from cold and lifeless effigies of the dead. Rollo and Mr. George advanced up the passage way as far as they could; and then, Mr. George making a signal for Rollo to follow him, they sat down on one of the benches where there was a vacancy, and began to listen to the music. This music came from an immense organ which was placed over the screen marked S on the plan, which, as you see, separates the nave from the choir. The tones of the organ were very deep and loud, and the sound reverberated from the arches and columns, and from the vaulted roofs above, in a very sublime and impressive manner. "Can't we go up a little nearer?" said Rollo. "We cannot get _seats_ any nearer," said Mr. George.
