I have now completed my literary survey of the first floor of the palace. At the desire of my noble and gracious patron, the lord of this glorious edifice, I next ascend to the second floor, and continue my catalogue or description of the pictures, decorations, and other treasures of art therein contained. Let me begin with the corner room at the western extremity of the palace, called the Room of the Caryatides, from the statues which support the mantel-piece. This work is of comparatively recent execution: it dates from the eighteenth century only, and reveals the corrupt taste of the period in every part of it. Still, there is a certain interest which attaches to the mantel-piece: it conceals a cleverly constructed hiding-place, between the floor of the room and the ceiling of the room beneath, which was made during the last evil days of the Inquisition in Venice, and which is reported to have saved an ancestor of my gracious lord pursued by that terrible tribunal. The machinery of this curious place of concealment has been kept in good order by the present lord, as a species of curiosity. He condescended to show me the method of working it. Approaching the two Caryatides, rest your hand on the forehead (midway between the eyebrows) of the figure which is on your left as you stand opposite to the fireplace, then press the head inwards as if you were pushing it against the wall behind. By doing this, you set in motion the hidden machinery in the wall which turns the hearthstone on a pivot, and discloses the hollow place below. There is room enough in it for a man to lie easily at full length. The method of closing the cavity again is equally simple. Place both your hands on the temples of the figures; pull as if you were pulling it towards you—and the hearthstone will revolve into its proper position again. “You need read no farther,” said the Countess. “Be careful to remember what you have read.” She put back the page of vellum in her writing-desk, locked it, and led the way to the door. “Come!” she said; “and see what the mocking Frenchman called ‘The beginning of the end.’” Agnes was barely able to rise from her chair; she trembled from head to foot. Henry gave her his arm to support her. “Fear nothing,” he whispered; “I shall be with you.” The Countess proceeded along the westward corridor, and stopped at the door numbered Thirty-eight. This was the room which had been inhabited by Baron Rivar in the old days of the palace: it was situated immediately over the bedchamber in which Agnes had passed the night. For the last two days the room had been empty. The absence of luggage in it, when they opened the door, showed that it had not yet been let. “You see?” said the Countess, pointing to the carved figure at the fire-place; “and you know what to do. Have I deserved that you should temper justice with mercy?” she went on in lower tones. “Give me a few hours more to myself. The Baron wants money—I must get on with my play.”
