On the second floor, as below, the hall extends entirely through the house, and following a frequent custom of the time was finished in a different order of architecture, the pulvinated Ionic being chosen, no doubt, for its lighter grace and greater propriety adjoining bedchambers. In furtherance of this thought, only the cornice with its jig-sawed modillions was employed at the ceiling and the flat dado was paneled off by the application of moldings to give it a lighter scale. The complete entablature was used only over the archway at the head of the stairs, where it was supported by square, fluted columns with beautifully carved capitals. Another mannerism of the time is the variation in the treatment of the doorways, the pedimental doorheads on one side being broken, whereas the others are not. But the handsomest features of this upper hall are the Palladian windows, admitting a flood of light at each end, with their rectangular sashes each side of a higher, round-arched central window and a delightful arrangement of curved sash bars at the top. The many small panes lend a pleasing sense of scale, while the architectural treatment of the frames adds to the charm of the interior woodwork quite as materially as to the exterior facade. In working out the scheme, the entire Ionic order is utilized on a small scale. Both the casings and the mullions take the form of fluted square columns with typical carved capitals. These support two complete entablatures forming the lintels of the rectangular windows and being carried around into the embrasure of the central window, the keyed arch of which springs from the entablatures. It is a design which has never been improved upon.
