Meantime we may endeavor to collect and compare the facts already known, and deduce therefrom some useful instruction to satisfy curiosity or gratify the greedy wish to ascend to the origin of every thing, and of mankind above all. The most proper and obvious way to elucidate American Antiquities and Monuments, would be by classifying them, which has however never been attempted, having always been noticed or elucidated loosely at random, or in a kind of geographical arrangement of the regions where found. Such classification might be based either on their styles, forms and materials, or ultimately their ascertained scopes of purposes which are even now often doubtful or doubted. They might thus be divided into classes or series easily distinguished between themselves, but all finding their equivalents or similar structures in the Eastern Continent, _an important fact_ to be kept in mind. There are out of America some structures not found in it, but there are none in it that cannot be detected somewhere else, either in Europe, North Africa or Asia, Polynesia, &c, among the earliest Monuments or Ruins, or the rudest structures. None of the latest styles and improved Architecture, such as Colonnades, roofed temples, Budhist and Mahometan temples, Gothic or Modern Churches, fortifications with large towers or bastions--are met in America, being a convincing proof that all the American structures were of a previous date, or of an earlier style, than these later. But even some very ancient Eastern structures are lacking in America, or only found in a modified form. Thus although the Cyclopian structures had been denied to America, they are not quite lacking; although their Tyrinthian style, the rudest of huge unshapen blocks of stone put together, has not yet been met with, the other Cyclopian styles are found of rough polygones or irregular squared stones: the most common however is of rough flat stones put together pretty much as our dry walls are to this day by us.
