This tract is seven hundred miles in length, and from one hundred to two hundred miles in breadth. Added to this, the whole of that country lying near the Alleghany River, and the streams that run into it, must naturally be supplied from the city; a great part of the country bordering upon Lake Erie, near Presqu’ Isle, may likewise be included. Considering the vastness of the territory, which is thus opened to the federal city by means of a water communication; considering that it is capable, from the fertility of its soil, of maintaining three times the number of inhabitants that are to be found at present in all the United States; and that it is advancing at the present time more rapidly in population than any other part of the whole continent; there is a good foundation for thinking that the federal city, as soon as the navigation is perfected, will increase most rapidly; and that at a future day, if the affairs of the United States go on as prosperously as they have done, it will become the grand emporium of the west, and rival in magnitude and splendor the cities of the old world. [Illustration: _Plan of the_ CITY _of_ WASHINGTON ] [Sidenote: CITY OF WASHINGTON.] The city is laid out on a neck of land between the forks formed by the eastern and western or main branch of Patowmac River. This neck of land, together with an adjacent territory, which is in the whole ten miles square, was ceded to congress by the states of Maryland and Virginia. The ground on which the city immediately stands was the property of private individuals, who readily relinquished their claim to one half of it in favour of congress, conscious that the value of what was left to them would increase, and amply compensate them for their loss. The profits arising from the sale that part of which has thus been ceded to congress will be sufficient, it is expected, to pay for the public buildings, for the watering of the city, and also for paving and lighting of the streets. The plan of the city was drawn by a Frenchman of the name of L’Enfant, and is on a scale well suited to the extent of the country, one thousand two hundred miles in length, and one thousand in breadth, of which it is to be the metropolis; for the ground already marked out for it is no less than fourteen miles in circumference. The streets run north, south, east, and west; but to prevent that sameness necessarily ensuing from the streets all crossing each other at right angles, a number of avenues are laid out in different parts of the city, which run transversely; and in several places, where these avenues intersect each other, are to be hollow squares. The streets, which cross each other at right angles, are from ninety to one hundred feet wide, the avenues one hundred and sixty feet. One of these is named after each state, and a hollow square also allotted to each, as a suitable place for statues, columns, &c. which, at a future period, the people of any
