At one point in the marginal, or sandy portion, 1.5 feet from the surface, was a deposit of calcined fragments of bone, some belonging to the turtle. This mound was evidently not a shell heap covered with sand, since the mass of shells, when encountered, did not present a sloping surface but showed an abruptly vertical surface 2 feet in height, very much as though the shells had been thrown into an excavation. No human remains or art relics, with the exception of one arrow head, were met with. LIGHT-HOUSE MOUND, FERNANDINA, NASSAU COUNTY The Light-house[8] mound, in a shell field and in the neighborhood of others, about 150 yards south of the light-house, probably one mile east of the town of Fernandina, was kindly placed at our disposal by Mr. E. D. Lukenbill of the Fernandina Development Company. Our thanks are tendered for numerous courtesies also to Mr. H. L. Linville, port warden of Fernandina. [Illustration: FIG. 6.—Section of mound northeast of Suarez Bluff.] The height of the mound, which was totally demolished by us, was 12 feet; the diameter of its base, 75 feet. It presented a very symmetrical appearance when stripped of the dense growth of vegetation which covered it, the ascent at some points being at an angle of 44°. Excavations 3 to 4 feet deep to the west and northwest of the base showed whence the material was derived. There had been some previous investigation on the immediate summit. COMPOSITION OF MOUND Structurally the mound was of considerable interest, the strata well defined. Immediately in a central position was a cone of white sand, surrounded and surmounted by the regular strata of the mound. The stratification of the mound from the top downward, a little north of the center, was as follows: 2 feet 6 inches—dirty brown sand. 1 foot—dark sand with oyster shells. 1 foot—pink sand mingled with oyster shells and with white sand. 5 feet 8 inches—yellow sand. 7 inches—dark sand and oyster shells. 2 feet—light sand to yellow sand of the base. At various points in the mound were pockets of sand artificially colored with _Hematite_. The distance between the summit of the mound at the center to the yellow sand at the base, where charcoal and human remains were wanting, was 15 feet. HUMAN REMAINS Exclusive of loose bits of bone, doubtless thrown from the previous excavation, seventy-four skeletons, all seemingly in anatomical order, were met with, and one deposit of charred and calcined human remains. We are, of course, unable to estimate the number of skeletons thrown out or carried away prior to our visit. The first interment was encountered 10 feet in from the southwestern margin of the base. With very few exceptions no art relics lay with human remains, and if we except a stone hatchet found with a skeleton 8 feet from the surface and some beads of shell with another interment, no art relics were associated with burials in the body or on the base of the mound.
