By the regulations published, it was settled that all the houses should be built of brick or stone; the walls to be thirty feet high, and to be built parallel to the line of the street, but either upon it or withdrawn from it, as suited the taste of the builder. However, numbers of wooden habitations have been built; but the different owners have all been cautioned against considering them as permanent. They are to be allowed for a certain term only, and then destroyed. Three commissioners, who reside on the spot, are appointed by the president, with a salary, for the purpose of superintending the public and other buildings, and regulating every thing pertaining to the city. The only public buildings carrying on as yet, are the president’s house, the capitol, and a large hotel. The president’s house, which is nearly completed on the outside, is two stories high, and built of free stone. The principal room in it is of an oval form. This is undoubtedly the handsomest building in the country, and the architecture cf it is much extolled by the people, who have never seen any thing superior; but it will not bear a critical examination. Many persons find fault with it, as being too large and too splendid for the residence of any one person in a republican country; and certainly it is a ridiculous habitation for a man who receives a salary that amounts to no more than £.5,625 sterling per annum, and in a country where the expences of living are far greater than they are even in London. [Sidenote: BUILDINGS.] The hotel is a large building of brick, ornamented with stone; it stands between the president’s house and the capitol. In the beginning of the year 1796, when I last saw it, it was roofed in, and every exertion making to have it finished with the utmost expedition. It is any thing but beautiful. The capitol, at the same period, was raised only a very little way above the foundation. The stone, which the president’s house is built with, and such as will be used for all the public buildings, is very similar in appearance to that found at Portland in England; but I was informed by one of the sculptors, who had frequently worked the Portland stone in England, that it is of a much superior quality, as it will bear to be cut as fine as marble, and is not liable to be injured by rain or frost. On the banks of the Patowmac they have inexhaustible quarries of this stone; good specimens of common marble have also been found; and there is in various parts of the river abundance of excellent slate, paving stone, and lime stone. Good coal may also be had.
