arrow-point; how in rude conditions of the arts the same instrument serves different purposes, as where the Fuegians use their arrow-heads also for knives, and Kafirs carve with their assagais, till separate forms are adopted for special purposes; and how in the history of the striking, cutting, and piercing instruments used by mankind, a continuity may be traced, which indicates a gradual progressive development from the rudest beginnings to the most advanced improvements of modern skill. To show how far the early development of warlike arts may have been due to man's imitative faculty, he points out the analogies in methods of warfare among animals and men, classifying as defensive appliances hides, solid plates, jointed plates, scales; as offensive weapons, the piercing, striking, serrated, poisoned kinds, &c.; and under the head of stratagems, flight, concealment, leaders, outposts, war-cries, and so forth.[1]
The manufacture of stone implements is now almost perfectly understood by archæologists. The processes used by modern savages have been observed and imitated. Sir John Evans, for instance, by blows with a pebble, pressure with a piece of stag's horn, sawing with a flint-flake, boring with a stick and sand, and grinding on a stone surface, succeeds in reproducing all but the finest kinds of stone implements.[2] On thorough knowledge we are now able to refer in great measure the remarkable similarities of the stone scrapers, flake-knives, hatchets, spear- and arrow-heads, &c., as found in distant times and regions, to the similarity of natural models, of materials, and of requirements which belong to savage life. The history of the Stone Age is clearly seen to be one of development. Beginning with the natural sharp stone, the transition to the
