The successive stages of the Mousterian industry have not as yet been so clearly defined as those of the Acheulean (Schmidt(70)). In the open Mousterian stations and caverns of Belgium and England Schmidt has observed the stages of early, middle, and late Mousterian. Breuil and Obermaier consider La Micoque as belonging to the close of the Acheulean but as marking the transition into the Mousterian. Breuil considers the industry of the Combe-Capelle station as representing the oldest true Mousterian culture. The researches which have been carried thus far would appear to justify the following subdivisions of the Mousterian culture in southwestern France: 6. Abri Audit culture, marking the transition from late Mousterian to early Aurignacian industry. 5. Late true Mousterian industry. La Quina type of implements with scrapers and bone anvils. 4. Middle Mousterian industry, with a predominance of handsome, large Mousterian points carefully 'retouched' on the edge and sometimes on one side, a 'retouch' at times approaching the superior Solutrean technique. 3. Primitive early Mousterian industry, with a limited inventory of implements. 2. Combe-Capelle stage, with heart-shaped coups de poing and typical Mousterian 'points.' (Arrival of reindeer.) 1. La Micoque culture, transitional from Acheulean to Mousterian times. (No reindeer.) The flint industry, although very different in its outward appearance, is recognizable as a direct evolution from the Acheulean, with the suppression or decline of certain implements and the improvements of others. It is the product of the same kind of mind at work with the same materials, but under different climatic conditions and with new demands, especially for clothing as protection against the severe weather. We also cannot avoid the feeling that the abandonment of the free, open life of Chellean and early Acheulean times and the crowding of the Neanderthal tribesmen beneath the shelters and in the grottos had a dwarfing effect both upon the physique and upon the industry itself. The Mousterian implements, as compared with the Acheulean, impress one as the work of a less muscular and vigorous race.
