At Spiennes, near Mons, a field was discovered, known as the _camp des cayaux_, strewn with flints, some uncut, others hewn, together with knives and hatchets innumerable. There were also centres of manufacture at Hoxne and Brandon, in England, at Bellaria in Bologna, and at Rome on the Tiburtine Way. At Ponte-Molle, where worked flints were discovered for the first time in Italy a few years ago, a workshop was found, remarkable for the great number of stags’ antlers, from which the middle part had been removed, doubtless to be used as handles for tools. M. de Rossi, who gives us these details, thinks that this station was inhabited in the Paleolithic period. In the settlement of Concise have been found not only stone implements, but a great many articles made of bone, so that this place was evidently an important manufacturing centre. Knives, stilettos, and arrow heads were turned out here, and in the hands of skilful workmen the tusks of the boars, which abounded at this time in Switzerland, were converted into excellent chisels.

In the commune of Saint-Julien du Saut we find a large manufactory where every division of the Stone age is fully represented, from the time of the simply chipped hatchet to that of the polished implement of rare perfection. Everything bears witness to the prolonged residence of man in a neighborhood which offered the attraction of vast deposits of chalk with bands of flint that supplied alike weapons and tools. Amongst others, we must name the so-called _atelier de la Treiche_, near Toul, which extends for an area of about a hundred acres, that of Bonaruc, near Dax; surrounded by waste lands covered with a scanty vegetation; that of Rochebertier (Charente), which probably dates from the Madeleine period; and that of Ecorche-Bœuf, near Périgueux. The Abbé Cochet tells us of an atelier in the Aulne valley, and Maurice Sand of another near La Châtre, where we meet with the most ancient traces of man in Berry. In the fields, near an alignment not far from Autun, were picked up numbers of hatchets of bard rock, barbed arrows, flakes of flint worked into scrapers or chisels, whilst near them were the very polishers on which they had been pointed. We have just spoken of polishers, and we said some time ago that it was by prolonged rubbing that the remarkable weapons of Neolithic times were produced. We must add now that a whole series of the polishers used are to be seen on the right bank of the Loing, near Nemours; one of which is a regular table (Fig. 72), on which can be made out no less than fifty grooves and twenty-five cup-like depressions.
