He came out of stone walls upon an airy platform whence the spire ascended heavenwards. His conductor led upward still, and he followed, winding within a spiral network of stone, through which all the world looked in. Another platform, and yet another spire springing from its basement. Still up they went, and at length stood on a circle of stone surrounding like a coronet the last base of the spire which lifted its apex untrodden. Then Robert turned and looked below. He grasped the stones before him. The loneliness was awful. There was nothing between him and the roofs of the houses, four hundred feet below, but the spot where he stood. The whole city, with its red roofs, lay under him. He stood uplifted on the genius of the builder, and the town beneath him was a toy. The all but featureless flat spread forty miles on every side, and the roofs of the largest buildings below were as dovecots. But the space between was alive with awe--so vast, so real! He turned and descended, winding through the network of stone which was all between him and space. The object of the architect must have been to melt away the material from before the eyes of the spirit. He hung in the air in a cloud of stone. As he came in his descent within the ornaments of one of the basements, he found himself looking through two thicknesses of stone lace on the nearing city. Down there was the beast of prey and his victim; but for the moment he was above the region of sorrow. His weariness and his headache had vanished utterly. With his mind tossed on its own speechless delight, he was slowly descending still, when he saw on his left hand a door ajar. He would look what mystery lay within. A push opened it. He discovered only a little chamber lined with wood. In the centre stood something--a bench-like piece of furniture, plain and worn. He advanced a step; peered over the top of it; saw keys, white and black; saw pedals below: it was an organ! Two strides brought him in front of it. A wooden stool, polished and hollowed with centuries of use, was before it. But where was the bellows? That might be down hundreds of steps below, for he was half-way only to the ground. He seated himself musingly, and struck, as he thought, a dumb chord. Responded, up in the air, far overhead, a mighty booming clang. Startled, almost frightened, even as if Mary St. John had said she loved him, Robert sprung from the stool, and, without knowing why, moved only by the chastity of delight, flung the door to the post. It banged and clicked. Almost mad with the joy of the titanic instrument, he seated himself again at the keys, and plunged into a tempest of clanging harmony. One hundred bells hang in that tower of wonder, an instrument for a city, nay, for a kingdom. Often had Robert dreamed that he was the galvanic centre of a thunder-cloud of harmony, flashing off from every finger the willed lightning tone: such was the unexpected scale of this instrument--so far aloft in the sunny air
