The great dining room, is, probably, one of the most highly finished apartments in America. The ceiling, especially, is a model; being composed of three elliptic domes for chandeliers. This room measures eighty-five by thirty-two feet, and twenty-seven high. The chimney pieces of the ladies' parlors are fine specimens of sculpture, and the rooms are otherwise handsome. The sleeping apartments are not excelled. The whole was designed and constructed by Dakin & Dakin, architects, in 1836-8, at a cost of $300,000, including the ground. ST. LOUIS HOTEL This building, as a hotel, may be considered as one of the most respectable in New Orleans. It stands nearly in the centre of the French portion of the population; and, in the combination of its brilliant and business-like appearance, is not an inappropriate representative of their national character. In this establishment the _utile et dulci_ are so happily blended, that the accomplished guest can find no cause of complaint. A more particular description of this superb edifice is omitted here, in consequence of its being given under the head of the City Exchange, to which the reader is respectfully referred. HEWLETT'S HOTEL This is a large and well-constructed building, on the corner of Camp and Common streets. It has been long known as a hotel, but, during the last year, has been opened, under new auspices, by the gentleman whose name has become associated with that of the house. The position is airy, healthy and central, and the table is said to be unexcelled. * * * * * The Planters' Hotel, in Canal street, and the National Hotel, in Tchoupitoulas street, are both good houses; and the prices being less, they are sought after by those who wish to economise their expenses. There are several other respectable establishments, of which, like those last named, the limits of these pages will not permit a particular description. * * * * * THE GAS WORKS
