A mound of shells, the accumulation of centuries and the result of countless Indian feasts, rose high above the southern marsh of Cumberland. A forest of live-oaks surrounded it on three sides, and at its feet ran the broad creek which wound through the marsh for miles, seeking the Sound at a point opposite the Florida shore. Here, for ages of time, the Indians of the South had resorted to feast upon the oysters with which the creek was filled. The Creek Indians--the most honorable with whom the United States ever had dealings, from whom sprang the Seminoles, and who occupied the entire territory of Georgia and Carolina at the period of the white man's advent--were the last who aided in the erection of this monument to a race now passed away. The summit of this shell-mound was levelled for the site of the house, and a terraced area of an acre or more constructed with the shells. Upon this base, raised above the general level of the island, its foundations were laid. It was four stories in height above the basement, and from cellar-stone to eaves was forty-five feet. There were four chimneys and sixteen fireplaces, and twenty rooms above the first floor. The walls at the base were six feet in thickness, and above the ground four feet. They were composed of the material known as "tabby," a mixture of shells, lime and broken stone or gravel with water; which mass, being pressed in a mould of boards, becomes when dry as hard and durable as rock. The walls are now as solid as stone itself. The second story above the terrace contained the principal rooms: the room in the south-east corner was the drawing-room in the time of the Shaws and the Nightingales. The room immediately back of the drawing-room, in the north-east corner, was the dining-room: a wide hall ran through the centre, upon the opposite side of which were two rooms, used respectively as school- and sewing-room. Above these apartments, in the third story, were the chambers. That directly above the drawing-room is the most interesting of all, for it was occupied by General Harry Lee, who was confined there by sickness, and there died. The interior of the house corresponded with its exterior in beauty of finish and magnificence of decoration and appointments.
