The flint implements of Grand-Pressigny, of which specimens can be seen in all the museums of Europe, are some sixteen inches long, of light color, pointed at one end and square at the other. One face is rough, the other chipped into three oblong pieces, whilst the sides are roughly hewn into saw-like teeth. If we examine these flints closely we can easily make out the exact point, the _eye_, as workmen call it, where the stone was struck. At Charbonnière, on the banks of the Saône, to quote other examples, in a radius of less than a mile, were found weapons, tools, and nuclei, which may be compared with those of Grand-Pressigny. In some places the collections of flints still remaining look as if they had been used for road-making. In some cases hatchets, knives, and scrapers seem to have been buried in pits. Were these the reserve stores of the tribe, or the so-called _caches_ of the merchants? It is difficult merely to name the different workshops or manufactories discovered in the last few years. We must, however, endeavor to mention the most important, for these workshops, we must repeat, are an important proof of the existence of a society of organized working communities. We meet with them on the shores of the bay of Kiel, in the island of Anholt, in the midst of the Kattegat, and on the borders of the Petchoura, and of the Soula, among the Samoieds. Virchow discovered an arrow-head manufactory on the shores of Lake Burtneek, and in 1884 the Moscow Society of Natural Sciences made known the existence of important workshops near the Vetluga River, in the province of Kostroma, so that we know that in remote prehistoric times men lived and fought in a rigorous climate in districts but sparsely populated in our own day. There is nothing to surprise us in all these facts. Recently near the Yenesei River, in the heart of Siberia, were found bronze daggers, hatchets and bridle bits (Fig. 71), all bearing witness in the beauty of their workmanship to a more advanced state of civilization than the Lake Dwellings or megalithic monuments farther south. Many of them are ornamented with figures of animals, so that at an epoch less remote, it is true, than the one we have been considering, but still far removed from our own, we find that there was an intelligent race, with artistic tastes, living in a country now so intensely cold as to be uninhabitable to all but a few miserable nomad Tartars.
