There are here several ranges of detached Sand Hills, running parallel with the River, the sides of which are almost perpendicular, destitute of vegetation, and so washed by the rains of thousands of years, as to present, at a distance, the appearances of Cities, Temples, Castles, Towers, Palaces, and every variety of great and magnificent structures.
