centuries; but I have not succeeded in finding any distinct evidence of the kind.
In the lower part of the Northern Continent, in Peru and some other districts of the Southern, the Stone Age was not extinct at the time of Columbus; it was indeed in a state of development hardly surpassed anywhere in the world, but at the same time several metals were in common use. Gold and silver were worked with wonderful skill, but chiefly for ornamental purposes. Though almost all the gold and silver work of Mexico has long ago gone to the melting-pot, there are still a few specimens which show that the Spanish conquerors were not romancing in the wonderful stories they told of the skill of the native goldsmiths. I have seen a pair of gold eagle ornaments in the Berlin Museum, which will compare almost with the Etruscan work for design and delicacy of finish. But what is still more important is that bronze, made of well-judged proportions of copper and tin, was in use on both continents. The Peruvians used bronze, and perhaps copper also, for tools and weapons. The Mexican bronze axe-blades are to be seen in collections, and we know by the picture-writings that both the Mexicans[1] and the builders of the ruined cities of Central America,[2] mounted them by simply sticking them into a wooden club, as the modern African mounts his iron axe-blade. The little bronze bells of Mexico[3] and South America are cored castings, which are by no means novice's work, and other bronze castings from the latter country are even more remarkable.[4]
How the arts of working gold, silver, copper, and bronze came into America, we do not know, nor can we even tell whether their appearance on the Northern and Southern Continent was independent or not. It is possible to trace Mexican connexion down to Nicaragua, and perhaps even to the Isthmus of Panama, while on the other hand the northern inhabitants of South America were not unacquainted with the nations farther down the continent. But no certain proof of connexion or intercourse of any kind between Mexico and Peru seems as yet to have been
