The shield-like portion of the second ornament is somewhat smaller, having amaximum length of inches, and a maximum width of inches. It is thinnerthan the larger shield, from which it differs in that it has repousse decoration onthe convex side alone, the concave side being undecorated and the excised portionfrom the upper part in the concave side does not end squarely, but has its basein the form of an upright wedge. Vegetable fabric, not shown in the cut (Fig. 41),adheres to the convex side which shows considerably less convexity than the largershield. From the convex side, as in the case of the other specimen, a band of sheetcopper, irregularly bent over, probably by weight of sand, projects as representedin section (Fig. 42a). Near the shield lay a band of copper about inches in CERTAIN RIVER MOUNDS OF DUVAL COUNTY, FLORIDA. 487 length, of the same breadth asof fracture shows a recent breaktwo portions do not join, it is. Fig. 41.—Ornament of sheet copper. Grant mound. (Full size.) according to the pattern shownFirst, the tongue, D, wasbent to a right angle withthe remaining portion. Thenthe sheet of the other side that portion projecting from the shield. The lineas does that of the band on the ornament. As theprobable an intervening portion is missing. Thisband of copper differs from that probably belong-ing to the larger shield, which is made of but onethickness of copper, in that it is constructed ofone sheet bent upon itself to give double thickness,the edges meeting at the margin. Dr. M. G. Miller, who has made a carefulexamination of the method of construction ofthese ornaments, writes as follows: The surfaces of both shields were obscuredby a thick coating of carbonate, the removal ofwhich required the use of acid. The smaller ornament consists of two on the concave side, smooth, undecoratedand showing no fissure in the me
