The dawn of the Palæolithic Age is indicated in various river-drift stations by the appearance of crude flint weapons as well as tools or implements, in addition to the supposed tools of Eolithic times. There is an unmistakable effort to fashion the flint into a definite shape to serve a definite purpose: there can no longer be any question of human handiwork. Thus there gradually arise various types of flints, each of which undergoes its own evolution into a more perfect form. Naturally, the workers at some stations were more adept and inventive than at others. Nevertheless, the primitive stages of invention and of technique were carried from station to station; and thus for the first time we are enabled to establish the archæological age of various stations in western Europe.

Only a few stations have been discovered where the Palæolithic men were first fashioning their flints into prototypes of the Chellean and Acheulean forms. With relation to the theory that these primitive flint workers may have entered Europe by way of the northern coast of Africa, we observe that these stations are confined to Spain, southern and northern France, Belgium, and Great Britain. Neither Pre-Chellean nor Chellean stations of unquestioned authenticity have been found in Germany or central Europe, and, so far as present evidence goes, it would appear that the Pre-Chellean culture did not enter Europe directly from the east, or even along the northern coast of the Mediterranean, but rather along the northern coast of Africa,[W] where Chellean culture is recorded in association with mammalian remains belonging to the middle Pleistocene Epoch.

The southernmost stations of Chellean culture at present known in Europe are those of Torralba and San Isidro, in central Spain. In the Department of the Gironde is the Chellean station of Marignac, and it is not unlikely that other stations will be discovered in the same region, because the Palæolithic races strongly favored the valleys of the Dordogne and Garonne, but thus far this is the only station known in southern France which represents this period of the dawn of human culture.

Very primitive palæoliths from Piltdown, Sussex, consisting chiefly of tools and points of triangular and oval form, fashioned out of flint nodules split in two and flaked on one side only, with very coarse marginal retouch. After Dawson. Nos. 1 and 2 are nearly one-half actual size; No. 3 nearly one-quarter actual size.

The chief Pre-Chellean and Chellean stations were clustered along the valleys of the Somme and Seine. Of those rare sites presenting a typical Pre-Chellean culture, we may note the neighboring stations of St. Acheul and Montières, both in the suburbs of Amiens on the Somme, and the station of Helin, near Spiennes, in Belgium, explored by Rutot. A very primitive and possibly Pre-Chellean culture was found on the site of the Champ de Mars, at Abbeville. This culture also extended westward across the broad plain which is now the Strait of Dover to the valley of the Thames, on whose northern bank is the important station of Gray's Thurrock, while farther to the south is the recently discovered site of Piltdown, in the valley of the Ouse, Sussex.

The flint tools (Fig. 60) found in the layer immediately overlying the Piltdown skull are excessively primitive and indicate that the Piltdown flint workers had not attained the stage of craftsmanship described by Commont as 'Pre-Chellean' at St. Acheul. "Among the flints," observes Dawson, "we found several undoubted flint implements besides numerous 'eoliths.' The workmanship of the former is similar to that of the Chellean or Pre-Chellean stage; but in the majority of the Piltdown specimens the work appears chiefly on one face of the implements."
