The structure shows three stories in front--on the second of which is the news room, expressly arranged for the occupation of the New Orleans Reading Room. This apartment is fifty-five by eighty-three feet, and thirty-seven to the ceiling; and is lighted by thirty-six windows. A portico, with a recess of eleven feet, occupies the immediate front, supporting the pediment by two Corinthian pillars, and an equal number of pilastres. Two rooms are set apart in connection with this establishment, one for the accommodation of captains of vessels, and one for that of sugar-brokers. On each side of the news-room are ranges of offices, to which admission is obtained by corridors on the inner side. Immediately over these, the third floor is arranged in the same manner. The intention of the company, under whose auspices this exchange is building, is, to furnish to the mercantile community a place solely for the transaction of business, similar to Lloyd's of London. There are to be no liquors sold on the premises. Mr. Gallier is the architect, and builder, and the building and land cost $90,000. [Illustration] THE MERCHANTS' EXCHANGE Fronting on Royal street and Exchange Place, was erected by a joint stock company in 1835-6, from the designs and under the superintendence of Mr. Dakin, architect. Both fronts are of marble, in a plain and bold style. The cost of the erection was $100,000. THE MERCHANTS' READING ROOM Entrance from Royal street and Exchange Place. This reading room occupied a spacious apartment in the second story of the Merchants' Exchange, and is under the patronage and control of the company interested in that building. It is generally supplied with most of the newspapers of the country, and has received a patronage quite equal to the extent of its accommodations. THE NEW ORLEANS READING ROOMS Occupy the second story of a spacious building on the corner of Common and St. Charles streets, opposite the Exchange and Verandah hotels. This is an enterprise started upon the plan of Galignani's, in Paris, and Lloyd's, in London--professing to supply the earliest commercial and general information. The fixtures are arranged with a degree of neatness and convenience that is extremely gratifying to the stranger, who has a spare hour to devote to reading. Here he can peruse the latest papers, not only from almost every section of the United States, but English, French, German, Mexican, Irish, Scotch, and Colonial, together with all the periodicals, to his heart's content. The merchant can see the prices current from nearly every part of the world; arrivals and departures of vessels and of travellers--sales of the great staples and merchandise and their prices, and many such matters of interest to the business man. * * * * * THE PUBLIC SCHOOLS
