RAFTSMAN Journal Jan 6 1858
Strange as it may appear, America ABOUNTS IN ANTIQUITIES, so extensive, so beautiful and majestic, as to rival those of THEBES OR NINEVEH. Ruins of ANCIENT CITIES, of IMMENSE extent, fortifications, MOUNDS AND PYRAMIDS, TEMPLES WITH WALLS, built of hewn stone SHOWING A REFINED TASTE IN ARCHITECTURE and adorned with human figures, BEAUTIFULLY execute.... remains of ANCIENT PALACES, with beautiful specimins of scupture and painting, with many other marks of ANCIENT GREATNESS, prove to us that THIS IS NOT A NEW WORLD, but that of a powerful empire existed at a very remote period of time, teeming with a population highliy skilled in arts, and in a STATE OF CIVILIZATION FAR BEYOND ANYTHING WE HAVE BEEN LED TO CONCEIVE OF THE ABORIGINES"
