Fig. 164.—Various shapes of Flint Arrow-heads, from the Lacustrine settlements of Switzerland.
The cutting of these small objects must have required much labour and skill. Some are toothed on the edges, which must have rendered the wounds inflicted by them much more dangerous. The greater part of these arrow-heads are made of flint, but some have been found the material of which is bone, and even stag's horn.
The arrow-heads were fixed into the shafts by means of bitumen. This plan is represented in figs. 165 and 166, which are given by M. Mortillet in his 'Promenades préhistoriques à l'Exposition Universelle.'
