During the first centuries of the Christian era, strange rites were still performed in honor of dolmens and menhirs. The councils of the Church condemned them, and the emperors and kings supported by their authority the decrees of the ecclesiastics.24 Childebert in 554, Carloman in 742, Charlemagne by an edict issued at Aix-la-Chapelle in 789,25 forbid their subjects to practise these rites borrowed from heathenism. But popes and emperors are alike powerless in this direction, and one generation transmits its traditions and superstitions to another. In the seventeenth century a Protestant missionary called in the aid of the secular arm to destroy a superstition deeply rooted in the minds of his people; in England, sorcerers were proceeded against for having used flint arrow-heads in their pretended witchcraft; in Sweden, a polished hatchet yeas placed in the bed of women in the pangs of labor; in Burmah, thunder-stones reduced to powder were looked upon as an infallible cure for ophthalmia; and the Canaches have a collection of stones with a special superstition connected with each. But why seek examples so far away and in a past so remote? In our own day anti in our own land we find men who think themselves invulnerable and their cattle safe if they are fortunate enough to possess a polished flint. 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.” [Illustration: 2.] Copper hatchets found in Hungary, and now in the National Museum of Budapest.
