The long bones of animals, with the walls of marrow-holes obliquely cut and exposing the hollow, were fastened upon sticks and poles, forming formidable darts and spears. The shape thus suggests the bamboo arrow-heads of the North Americans, whose cavity also served to carry poison.[82] They would, moreover, easily be fashioned by fracture, and by friction upon a hard and rough-grained substance, into Swords and daggers. The Fenni, or Finns, of Tacitus (‘Germ.’ c. 46), having no iron, used bone-pointed arrows. The Innuits, or Eskimos, of Greenland and other parts of the outer north, form with the ribs of whales their shuttles as well as their Swords. In ‘Flint Chips’ we find that the ancient Mexicans had bone-daggers. Wilde[83] gives a unique specimen of such a weapon found in the bed of the River Boyne ‘in hard blue clay, four feet under sand, along with some stone spear-heads.’ Formed out of the leg-bone of one of the large ruminants, it measures ten and a sixth inches long, the rough handle being only two and a half inches[84]; the blade is smooth, and wrought to a very fine point. This skeyne (the Irish ‘scjan’[85]) looks like a little model of a metal cut-and-thrust blade (fig. 27). Equally interesting is the knife-blade (fig. 29) found with many other specimens of manufactured bone in the Ballinderry ‘Crannog’[86] (county Westmeath): the total length is eight inches, and the handle is highly decorated. Other bone knives are mentioned in the ‘Catalogue’ (pp. 262–63). Bone prepared for making handles, and even ferules, for Swords and daggers is also referred to (p. 267): the material, being easily worked and tolerably durable, has, indeed, never fallen into disuse. In the shape of ivory,[87] walrus-tusk, and hippopotamus-tooth it is an article of luxury extensively used in the present day for the hafts of weapons and domestic implements. Lastly, bone served as a base to carry mere trenchant substances. The museum of Professor Sven Nilsson[88] shows (fig. 31) a smooth, sharp-pointed splinter, some six inches long, grooved in each side to about a quarter of an inch deep. In each of these grooves, fixed by means of cement, was a row of sharp-edged and slightly curved bits of flint. A similar implement (fig. 30) is represented in the illustrated catalogue of the Museum of Copenhagen. Of this contrivance I shall speak at length when treating of the wooden Sword.[89] [Illustration: FIG. 26.—1. BONE ARROW-POINT FOR POISON; 2. IRON ARROW-HEAD FOR POISON. (S.
