The Swiss lakes have furnished us with elements which afford us some knowledge of the state of man's industrial skill during the bronze epoch, and also enable us to form a due estimation of the manners and customs of the people of these remote ages. But if we wish to become acquainted with all the details which concern the art of war at the same date, we must direct our attention to the north of Europe, that is to say, to the Scandinavian peoples. Nevertheless, before we touch upon the important pre-historic relics found in Denmark, we must say a few words concerning the traces of the art of war which have been furnished by the investigations made in the Swiss lakes. The warlike accoutrements of the bronze epoch are, like those of the Stone Age, composed of spear-heads and arrow-heads, poniards and, in addition, swords. Swords are, however, but rarely met with in the Swiss lakes. The few which have been found are straight, short, double-edged, and without hilts. In the Museum of Neuchâtel there is a sword (fig. 209) which was discovered forty years ago at Concise, at a time when no one suspected the existence of any such thing as lacustrine settlements; M. Desor has supplied a sketch of it in his 'Mémoire sur les Palafittes.' This sword measures 16 inches in length, and has on its surface four grooves which join together on the middle ridge of the blade. The handle, which is terminated by a double volute, is remarkably small, being only 3 inches in length. Daggers (fig. 210), too, like the swords, are but rarely found in the Swiss lakes. From a specimen found in the lake of Bienne, we see that the blade was fixed to the handle by means of a series of rivets arranged in a single line. This dagger is, like the sword found at Concise, ornamented with grooves symmetrically placed on each side of the projecting ridge which divides the blade into two equal portions. [Illustration: Fig. 209.--Bronze Sword, in the Museum of Neuchâtel.] [Illustration: Fig. 210.--Bronze Dagger, found in one of the Swiss Lakes.] In the collection of Colonel Schwab, there are two daggers of an extraordinary character, having hilts enriched with silver. The spear-heads (fig. 211) are not inferior either to the swords or the daggers in the skill and finish of their workmanship. They are formed of a nearly oval blade, strongly consolidated in the middle by a rounded ridge, which is prolonged so as to form a socket intended to hold a thick wooden handle. The length of the daggers varies from 4 to 7 inches. [Illustration: Fig. 211.--Bronze Spear-head, found in one of the Swiss Lakes.] The arrow-heads (fig. 212) are, except in their material, identical with those of the preceding age. They are triangular, with more or less pointed barbs, and provided with a stem, by which they were fastened to the stick. A few have, however, been found which are made with sockets. They do not exceed 1 to 2 inches in length.
