If we compare the small, often tiny, knives and flint flakes from the German places with the powerful axes and lance-heads of those regions, it is self-evident how much more laborious life must have been for the man who used the former. What labour he must have expended in carving weapons and implements out of bone and horn, while flint supplied the others with much better and more lasting ones with less expenditure of time and trouble! In this light a wealth of flint was a civilising factor of that period which is not to be under-estimated. In the flint districts not only are the stone implements better worked, answering in a higher degree the purpose of the weapon and the tool, but delight in ornament and decoration is also more prominent. [Sidenote: The Life in the Caves] [Sidenote: Drift Man as Artist] Life in the caves and grottos and under the rock shelters in the neighbourhood of rivers was by no means quite wretched. The remains left in the caves by their former inhabitants give almost as clear an idea of the life of man in those primeval times as the buried cities of Herculaneum and Pompeii do of the manners and customs of the Italians in the first century of the Christian era. The floors of these caves in which men formerly lived appear to consist entirely of broken bones of animals killed in the chase, intermixed with rude implements and weapons of bone and unpolished stone, and also charcoal and large burnt stones, indicating the position of fireplaces. Flints and chips without number, rough masses of stone, awls, lance-heads, hammers, and saws of flint and chert lie in motley confusion beside bone needles, carved reindeer antlers, arrow-heads and harpoons, and pointed pieces of horn and bone; in addition to which are also the broken bones of the animals that served as food, such as reindeer, bison, horse, ibex, saiga antelope, and musk-ox. The reindeer supplied by far the greater part of the food, and must at that time have lived in Central France in large herds and in a wild state, all trace of the dog being absent.
