I shall have to bring in many unfamiliar words for the names of the industries. The industries are usually named after the places where they were first found, and since these were in most cases in France, most of the names which follow will be of French origin. However, the names have simply become handles and are in use far beyond the boundaries of France. It would be better if we had a non-place-name terminology, but archeologists have not yet been able to agree on such a terminology. THE ACHEULEAN INDUSTRY Both in France and in Palestine, as well as in some African cave sites, the next layers in the deep caves have an industry in both the core-biface and the flake traditions. The core-biface tools usually make up less than half of all the tools in the industry. However, the name of the biface type of tool is generally given to the whole industry. It is called the _Acheulean_, actually a late form of it, as “Acheulean” is also used for earlier core-biface tools taken from the glacial gravels. In western Europe, the name used is _Upper Acheulean_ or _Micoquian_. The same terms have been borrowed to name layers E and F in the Tabun cave, on Mount Carmel in Palestine. The Acheulean core-biface type of tool is worked on two faces so as to give a cutting edge all around. The outline of its front view may be oval, or egg-shaped, or a quite pointed pear shape. The large chip-scars of the Acheulean core-bifaces are shallow and flat. It is suspected that this resulted from the removal of the chips with a wooden club; the deep chip-scars of the earlier Abbevillian core-biface came from beating the tool against a stone anvil. These tools are really the best and also the final products of the core-biface tradition. We first noticed the tradition in the early glacial gravels (p. 43); now we see its end, but also its finest examples, in the deeper cave levels. The flake tools, which really make up the greater bulk of this industry, are simple scrapers and chips with sharp cutting edges. The habits used to prepare them must have been pretty much the same as those used for at least one of the flake industries we shall mention presently. There is very little else in these early cave layers. We do not have a proper “industry” of bone tools. There are traces of fire, and of animal bones, and a few shells. In Palestine, there are many more bones of deer than of gazelle in these layers; the deer lives in a wetter climate than does the gazelle. In the European cave layers, the animal bones are those of beasts that live in a warm climate. They belonged in the last interglacial period. We have not yet found the bones of fossil men definitely in place with this industry. [Illustration: ACHEULEAN BIFACE] FLAKE INDUSTRIES FROM THE CAVES
