Prehistoric times are generally divided into three epochs—the Stone Age, the Bronze Age, and the Iron Age. We owe this classification to the archæologists of Northern Europe.[26] It is neither very exact nor very satisfactory, and fresh discoveries daily tend to unsettle it.[27] Alsberg maintained that iron was the first metal used, founding his contention on the scarcity of tin, the difficulty of obtaining alloys, and on the sixty-one iron foundries of Switzerland which may date from prehistoric times. The rarity of the discovery of iron objects, he urged, is accounted for by the ease with which such objects are destroyed by rust. There has never been a Bronze or an Iron age in America, so that it would seem very doubtful whether all races went through the same cycles of development. I myself prefer the division into the Palæolithic period, when men only used roughly chipped stones, and the Neolithic period, when they carefully polished their stone weapons. “There may,” says Alexander Bertrand,[28] “be one immutable law for the succession of strata throughout the entire crust of the earth, but there is no corresponding law applicable to human agglomerations or to the succession of the strata of civilization. It would be a very grave error to adopt the theory according to which all human races have passed through the same phases of development and have gone through the same complete series of social conditions.”

It may perhaps be convenient to introduce a fourth period when copper alone was used and our ancestors were still ignorant of the alloys necessary for the production of bronze. Hesiod speaks of a third generation of men as possessing copper only, and although it does not do to attach undue importance to isolated facts, recent discoveries in the Cevennes, in Spain, in Hungary, and elsewhere, appear to confirm the existence of an age of copper ([a]Fig. 2]). We may add that the mounds of North America contain none but copper implements and ornaments, witnesses of a time when that metal alone was known either on the shores of the Atlantic or of the Pacific[29] ([Fig. 3]).

It is impossible to fix the duration of the Stone age. It began with man, it lasted for countless centuries, and we find it still prevailing amongst certain races who set their faces against all progress. The scenes sculptured upon Egyptian monuments dating from the ancient Empire represent the employment of stone weapons, and their use was continued throughout the time of the Lagidæ and even into that of the Roman domination. A few years ago, on the shores of the Nile, I saw some of the common people shave their heads with stone razors, and the Bedouins of Gournah using spears headed with pointed flints. The Ethiopians in the suite of Xerxes had none but stone weapons, and yet their civilization was several centuries older than that of the Persians. The excavations on the site of Alesia yielded many stone weapons, the glorious relics of the soldiers of Vercingetorix. At Mount Beuvray, on the site of Bibracte, flint hatchets and weapons have been discovered associated with Gallic coins. At Rome, M. de Rossi collected similar objects mixed with the Æs rude. Flint hatchets are mentioned in the life of St. Éloy, written by St. Owen, and the Merovingian tombs have yielded hundreds of small cut flints, the last offerings to the dead. William of Poitiers tells us that the English used stone weapons at the battle of Hastings in 1066, and the Scots led by Wallace did the same as late as 1288. Not until many centuries after the beginning of the Christian era did the Sarmatians know the use of metals; and in the fourteenth century we find a race, probably of African origin, making their hatchets, knives, and arrows of stone, and tipping their javelins with horn. The Japanese, moreover, used stone weapons and implements until the ninth and even the tenth century A.D.

But there is no need to go back to the past for examples. The Mexicans of the present day use obsidian hatchets, as their fathers did before them; the Esquimaux use nephritis and jade weapons with Remington rifles. Nordenskiöld tells us that the Tchoutchis know of no weapons but those made of stone; that they show their artistic feeling in engravings on bone, very similar to those found in the caves of the south of France. In 1854, the Mqhavi, an Indian tribe of the Rio Colorado (California), possessed no metal objects; and it is the same with the dwellers on the banks of the Shingle River (Brazil), the Oyacoulets of French Guiana, and many other wandering and savage races. Père Pelitot tells us that the natives living on the banks of the Mackenzie River are still in the stone age; and Schumacker has given an interesting example of the manufacture of stone weapons by the Klamath Indians dwelling on the shores of the Pacific. It has been justly said: “The Stone age is not a fixed period in time, but one phase of the development of the human race, the duration of which varies according to the environment and the race.”[30]
