Though the ceilings of the two drawing-rooms should not be much ornamented, yet they may be relieved by the introduction of gilding in parts. For all these rooms I propose that the doors, &c. should be white with gilt mouldings. In the library, the ribs or bands of the vaulted ceiling should be gilt upon a white ground; and as regards the bookcases or shelves for books, they ought to be of some light coloured wood, highly polished, and not go higher than the corbels or consoles from which the vaulting springs, in order that there may be sufficient space for busts, vases, and other ornaments of that kind upon the cornices; and this will avoid the inconvenience of having the upper shelves quite out of reach, except with the help of high library steps--always inconvenient. For the lunettes or arched spaces between the corbels, I have not proposed any particular decoration, as they might be filled up by reliefs and casts let into the wall. The dining room with the arcs-doubleaux and compartments of its vaulted ceiling afford scope for fresco painting of a superior style; and the pencil of our friend Eastlake, who has already shown so much classical talent in decorating the dining-room in London, might render this one of the most striking and charming apartments of its kind in England. It is true that fresco is so little practised in your country, and consequently its process so imperfectly understood, that he would probably have to encounter some difficulties at the outset; but I flatter myself I could be of considerable assistance to him, as regards the practical details, having already succeeded in introducing that mode of painting in spite of most unfavourable circumstances. I would advise that the pictures should be confined to the ceiling and the lunettes, and that the walls should be merely stuccoed, as being upon the whole more in accordance with the destination of the room itself, and affording a quieter background to the company seated around the dinner-table; at the same time that the frescoes in the upper part of the room would thereby show to greater advantage. You will observe that the fresco requires a bold broad style, and has an advantage over oil, as it is very effective even when not seen by a strong or favourable light. Should somewhat more of decoration be thought advisable, I would suggest the adoption of glass-mosaic in narrow upright pannels at intervals. Of this species of embellishment, which was much used by the Romans, and after, much in vogue throughout Italy during the middle ages, for pulpits, monuments, &c. I have lately introduced an application in a room fitted up by myself, the effect of which is allowed to be singularly striking and good. The remaining drawing shows the large corridor on the upper floor.
