Then came in the Age of Bronze, introduced from abroad, probably from the East, as its great depôt was in the basin of the Po. Next arrived the Gauls, armed with weapons of iron. They were subjugated by the Romans, and Roman Gaul in turn became a prey to the Goth and the Frank. History has begun and is in full swing. The mediæval period succeeded, and finally the modern age, and man now lives on top of the accumulation of all preceding epochs of men and stages of civilisation. In no other part of France, indeed of Europe, is the story of man told so plainly, that he who runs may read; and ever since the middle of last century, when this fact was recognised, the district has been studied, and explorations have been made there, some slovenly, others scientifically. A few years ago I was induced to visit this remarkable region and to examine it attentively. I had been furnished with letters of recommendation from the authorities of the great Museum of National Antiquities at St. Germain, to enable me to prosecute my researches unmolested by over-suspicious gendarmes and ignorant mayors. Under one over-hanging rock was a cabaret or tavern, announcing that wine was sold there, by a withered bush above the door. The place seemed to me to be a probable spot for my exploration. I entered into an arrangement with the proprietor to enable me to dig, he stipulating that I should not undermine and throw down his walls. I engaged six labourers, and began proceedings by driving a tunnel some little way below the tavern into the vast bed of débris. The upper series of deposits did not concern me much. The point I desired to investigate, and if possible to determine, was the approximate length of time that had elapsed between the disappearance of the reindeer hunters and the coming on the scene of the next race, that which used polished stone implements and had domestic animals. Although it may seem at first sight as if both races had been savage, as both lived in the Stone Age, yet an enormous stride forward had been taken when men had learned the arts of weaving, of pottery, and had tamed the dog, the horse, and the cow. These new folk had passed out of the mere wild condition of the hunter, and had become pastoral and to some extent agricultural. Of course, the data for determining the length of a period might be few, but I could judge whether a very long or a very brief period had elapsed between the two occupations by the depth of débris--chalk fallen from the roof, brought down by frost, in which were no traces of human workmanship. It was with this distinct object in view that I drove my adit into the slope of rubbish some way below the cabaret, and I chanced to have hit on the level of the deposits of the men of bronze. Not that we found much bronze--all we secured was a broken pin--but we came on fragments of pottery marked with the chevron and nail and twisted thong ornament peculiar to that people and age.
