The gentlemen's dining and sitting rooms occupy the whole side of the building on Gravier street. The dining room, with a pantry at the end, is one hundred and twenty-nine feet long by fifty wide, and twenty-two feet high, tastefully finished in the Corinthian order, with two inside ranges of columns, so placed that there is abundant space for four ranges of dining tables, sufficient to accommodate five hundred persons. The ladies' dining room is placed over the bathing apartments, and is fifty-two by thirty-six feet. The kitchen, fifty-eight by twenty-nine feet, is placed in the rear wing of the building, on the same story with, and in the centre between the two dining rooms. The two angles of the principal front contain the ladies' drawing room, and the gentlemen's sitting room, the former forty by thirty-two feet, the latter thirty-eight feet square. There are nine private parlors on the second story, to some of which are attached adjoining bedrooms; and the same number on the upper stories. There are four stories of elegantly furnished and well lighted bedrooms, all around the four sides of the building, with central passages, or corridors, which communicate with the centre and with each other, having three stair-cases opening to the corridors, besides the grand stair-case in the octagon. There are, in the edifice, three hundred and fifty rooms. A dome, of beautiful proportions, after a plan of Dakin, forty-six feet in diameter, surmounts the octagon building, elevated upon an order of fluted columns, which stand eleven feet from the dome, around the outside, and on the dome is elevated an elegant little Corinthian turret. There is a large circular room under the dome, on the floor of which the spiral stair-case terminates, and around the outside of which the circular colonade forms a beautiful gallery eleven feet wide, from whence can be seen the whole city, and all the windings of the river for several miles in each direction. The effect of the dome upon the sight of the visitor, as he approaches the city, is similar to that of St. Paul's, London. No better evidence can be adduced--nor more flattering encomiums presented to the architects, than the fact of the indescribable effect of the sublime and matchless proportions of this building upon all spectators--even the stoical Indian and the cold and strange backwoodsman, when they first view it, are struck with wonder and delight. The view of this structure by moonlight is a sight not easily described. The furnishing of this establishment cost $150,000. [Illustration] THE VERANDAH So called from being covered on its front toward the streets, to a certain height, by a projecting roof and balcony, is situated at the corner of St. Charles and Common streets, diagonally opposite the Exchange Hotel. The building was intended for a family hotel, by its enterprising projector and builder, the late R. O. Pritchard.
