Mr. Fearon remained at Pittsburgh several days, during which time the rain never ceased. The smoke, also, from the different manufactories, is extreme, giving, to the town and its inhabitants, a very sombre aspect. The articles manufactured here are various, and chiefly of copper, iron, and glass. In one of the glass-warehouses, Mr. Fearon saw chandeliers and numerous other articles, of a very splendid description, in cut glass. Among the latter was a pair of decanters, cut from a London pattern, the price of which was to be eight guineas. And it is remarkable that the demand for these articles of elegant luxury lies in the western states; the inhabitants of eastern America being still importers from the "old country." Not thirty years ago, the whole right bank of the Ohio was termed the "Indian side." Spots in Tenessee, in Ohio and Kentucky, which, within the lifetime of even young men, witnessed only the arrow and the scalping knife, now present, to the traveller, articles of elegance, and modes of luxury, which might rival the displays of London and of Paris: within the last half century, the beasts of the forest, and men more savage than the beasts, were the only inhabitants of the whole of that immense tract, which is peculiarly denominated the western country. This tract is now partially inhabited; and promises soon to be generally so, by civilized man, possessed of the arts and pursuits of civilized life. On the whole, Pittsburgh is a very important town. When Mr. Fearon was here, it was supposed to contain about ten thousand inhabitants. The face of the country, beyond this town, is an uninterrupted level, and many parts of it are occupied by agriculturists. Mr. Fearon, however, was informed that there were still for sale one million of acres of United States' land, at the rate of two dollars per acre, or one dollar and sixty-four cents for prompt payment. The principal towns are situated on the banks of the river. There are no canals, nor, indeed is there much occasion for them, as the whole state abounds with rivers and creeks, which fall into the Ohio. The trees produced by the best kind of land are honey-locust, black walnut, and beech; by land of second quality, the sugar maple tree, sycamore, or butter-wood, and what is called white wood, which is used for building and joiner's work; and land of the third quality produces oak. There is but little underwood; for the great height and the spreading tops of the trees, prevent the sun from penetrating to the ground, and nourishing inferior articles of vegetation.
