The Acheulean stations are widely distributed along the Seine, Marne, and Somme in northern France, where flint is abundant and well adapted for fine workmanship. In central and southern France, where large flints are scarce, the Acheulean tribes were forced to use quartz, which fashions into clumsier forms. In the north the Acheulean workers continued on the old Chellean sites at Chelles, St. Acheul, Abbeville, and Helin. In late Acheulean times were established the new stations of Wolvercote on the Thames, near Oxford, and of Levallois on the Seine, near Paris, both famous for their 'Levallois' flint knives or blades. Near Levallois is the late Acheulean station of Villejuif, south of Paris, where the flints are buried in drifts of loess. In Normandy are the important stations of Frileuse, Bléville, and La Mare-aux-Clercs, which give the whole Acheulean development, both early and late. On a small tributary valley of the Vézère, in Dordogne, in late Acheulean times there was established the station of La Micoque, which gives its name to a number of miniature flints of distinctive form which were first found there and are known as the 'type of La Micoque.' Other stations, such as Combe-Capelle, also show examples of this 'miniature' Acheulean workmanship. [Illustration: FIG. 80. Distribution of the principal Acheulean industrial stations in western Europe.] Altogether, over thirty Acheulean stations have been found in France, two--Castillo and San Isidro--in northern and central Spain, the single station of Furninha in Portugal, over eight in Germany, three in Austria, and three in Russian Poland. Especially remarkable is the wide distribution of this culture all over Italy, where explorations by no means exhaustive have resulted in the discovery of at least nine or ten very prolific stations extending from Goccianello in the north to Capri in the south, but not into Sicily as far as is at present known. Thus all of western Europe, excepting the area covered by the Scandinavian ice-fields on the north and by the Alpine ice-fields on the south, was penetrated by the workers of Acheulean flints, probably members, for the most part, of the Neanderthal race.
