Another interesting variety of shell implement is shown in Fig. 1, Plate XXVI. It was obtained from the Oconee River, near Milledgeville, Ga., and is made from the left valve of a _Unio vericosus_. Its perfect state of preservation indicates that it is of quite recent manufacture. A deep, sharply cut groove encircles the beak and hinge of the shell, and the posterior margins are considerably worn. A few shallow lines have been engraved on the smooth convex surface of the valve. The position of the groove suggests the method of hafting shown in Fig. 2. Fig. 6, Plate XXVI, represents a perforated _Pecten_, which may have been used as an implement or as part of a rattle. It was collected by Mr. Webb on the west coast of Florida. [Illustration: PL.

The first explorers of the Atlantic seaboard found many of the tribes cultivating the soil to a limited extent, corn being the chief product. The methods and appliances were exceedingly primitive, and the implements employed, whether wood, bone, stone, or shell, possess but little interest to art. Unworked shells, lashed to rude handles, served all the purposes as well as if wrought out in the most fanciful manner. The large, firm valves of clam-shells were most frequently used, as the following extracts will show. "Before the Indians learned of the English the use of a more convenient instrument, they tilled their corn with hoes made of these shells, to which purpose they are well adapted by their size."[42] A further reference to this shell is found in Wood's New England Prospect: "The first plowman was counted little better than a Juggler: the _Indians_ seeing the plow teare up more ground in a day, than their Clamme shels could scrape up in a month, desired to see the workemanship of it, and viewing well the coulter and share, perceiving it to be iron, told the plowman, hee was almost _Abamocho_, almost as cunning as the Devill."[43] And again the same author says: "An other work is their planting of corne, wherein they exceede our _English_ husband-men, keeping it so cleare with their Clamme shell-hooes, as if it were a garden rather than a corne-field, not suffering a choking weede to advance his audacious head above their infant corne, or an undermining worme to spoile his spurnes."[44]
