There is a wide-spread error on the subject of American scenery. From the size of the lakes, the length and breadth of the rivers, the vast solitudes of the forests, and the seemingly boundless expanse of the prairies, the world has come to attach to it an idea of grandeur; a word that is in nearly every case, misapplied. The scenery of that portion of the American continent which has fallen to the share of the Anglo-Saxon race, very seldom rises to a scale that merits this term; when it does, it is more owing to the accessories, as in the case of the interminable woods, than to the natural face of the country. To him who is accustomed to the terrific sublimity of the Alps, the softened and yet wild grandeur of the Italian lakes, or to the noble witchery of the shores of the Mediterranean, this country is apt to seem tame, and uninteresting as a whole; though it certainly has exceptions that carry charms of this nature to the verge of loveliness. Of the latter character is the face of most of that region which lies in the angle formed by the junction of the Mohawk with the Hudson, extending as far south, or even farther, than the line of Pennsylvania, and west to the verge of that vast rolling plain which composes Western New York. This is a region of more than ten thousand square miles of surface, embracing to-day, ten counties at least, and supporting a rural population of near half a million of souls, excluding the river towns. All who have seen this district of country, and who are familiar with the elements of charming, rather than grand scenery it possesses, are agreed in extolling its capabilities, and, in some instances, its realities. The want of high finish is common to everything of this sort in America; and, perhaps we may add, that the absence of picturesqueness as connected with the works of man, is a general defect; still, this particular region, and all others resembling it--for they abound on the wide surface of the twenty-six states--has beauties of its own, that it would be difficult to meet with in any of the older portions of the earth. They who have done us the honour to read our previous works, will at once understand that the district to which we allude, is that of which we have taken more than one occasion to write; and we return to it now, less with a desire to celebrate its charms, than to exhibit them in a somewhat novel, and yet perfectly historical aspect. Our own earlier labours will have told the reader, that all of this extended district of country, with the exception of belts of settlements along the two great rivers named, was a wilderness, anterior to the American revolution.
