There has also been discovered a kind of prismatically shaped hexagonal hammer (fig. 181), likewise provided with a socket, the length of which is about 3 inches. This hammer forms a portion of the collection of Colonel Schwab. The knives are the most numerous of all the sharp instruments. The workmanship of them is, in general, very skilfully executed, and their shape is very elegant. Some of them have a metallic handle; but the greater part terminate in a kind of tang intended to fit into a handle of wood or stag's horn, as represented in fig. 182, taken from M. Desor's 'Mémoire sur les Palafittes.' We also find knives furnished with a socket (fig. 183). The blade measures from 4 to 8 inches in length, and is often adorned with tracings; in some instances the back of the blade is very much thickened. [Illustration: Fig. 183.--Socketed Knife, from the Lacustrine settlements of Switzerland.] Together with the knives we must also class the sickles or reaping hooks. These implements have been collected in somewhat large quantities in the settlements of Auvernier and Cortaillod (Lake of Neuchâtel). They are of good workmanship, and frequently provided with ridges or ribs in the metal of the blade. Fig. 184, given by M. Desor in his work, represents a sickle of this kind which was found by the author at Chevroux. [Illustration: Fig. 184.--Bronze Sickle, found by M. Desor at Chevroux.] The largest of these sickles does not exceed 6 inches in length. They were fitted into a wooden handle. We cannot of course describe all the bronze objects which have been recovered from the Swiss lakes. After having mentioned the preceding, we shall content ourselves with naming certain saws of various shapes--razors, actual razors, indicating no small care given to personal appearance--bodkins, or piercers--needles, with eyes either at the end or some distance from the end, articles of fishing tackle, such as single and double fishing-hooks (figs. 185 and 186), with a plain or barbed point--harpoons, various small vessels, &c. [Illustration: Fig. 185.--Bronze Fish-hook, from the Lacustrine settlements of Switzerland.] [Illustration: Fig. 186.--Double Fish-hook, from the Lacustrine settlements of Switzerland.] We shall dwell, although briefly, on the various objects of personal ornament which have been found in the Swiss lacustrine settlements of the bronze epoch. We will mention, in the first place, the hair-pins, &c. which have been recovered from the various lakes. The most curious fact about them is, that no one has ever found two exactly alike both in shape and dimensions. We borrow from M. Desor's work the four following figures representing various shapes of pins. Some have a round head (fig. 187), and others a flat (fig. 188), or cylindrical head (fig. 189); others, again, are finished off with a twisted end to which is attached a movable end (fig. 190).
