On the 22nd of March, 1819, about nine o'clock in the morning, a young man, some twenty-three or twenty-four years old, wearing the dress of a German student, which consists of a short frock-coat with silk braiding, tight trousers, and high boots, paused upon a little eminence that stands upon the road between Kaiserthal and Mannheim, at about three-quarters of the distance from the former town, and commands a view of the latter. Mannheim is seen rising calm and smiling amid gardens which once were ramparts, and which now surround and embrace it like a girdle of foliage and flowers.
