Some people have thought that they discovered in the traces of fires which had been sometimes lighted before caves in which were found human skeletons, the indication of sepulchral rites, and that these caves were used as burial-places. But these suppositions are too vague and uncertain to be relied upon. It may, however, be said that we have evidence pointing to the fact that even in the drift period men buried their dead, and it is hardly possible to believe that they did so without paying some obsequies to the remains. On this interesting subject of sepulchral rites we must forbear to say anything until we come to speak of the second stone age. Our knowledge of the early stone-people must close with the slight picture we have been able to form of their life; of their death, of their rites of the dead, and the ideas concerning a future state which these might indicate, we cannot speak. This, then, is all we know of man of the first stone age, and it is not probable that our knowledge will ever be greatly increased. New finds of these stone implements are being made almost every day, not in Europe only, though at present chiefly there, but in many other parts of the globe. But the new discoveries closely resemble the old, the same sort of implements recur again and again, and we only learn by them over how great a part of the globe this stage in our civilization extended. Further information of this kind may change some of our theories concerning the duration or the origin of this civilization, but it will not add much to our knowledge of its nature. Yet it cannot be denied that the thought of man’s existence only, though we know little more than this, a contemporary of the mammoth at the time which immediately succeeded the glacial period, or perhaps before the glacial period had quite come to an end, is full of the deepest interest for us. The long silent time which intervenes between the creation of our first parents and those biblical events whereof the narration is to a certain extent continuous and consecutive, till the dawn of history in the Bible narrative in fact, is to some small extent filled in. We shall see in the next chapter how the second stone age serves to carry the same picture further. In rudest outline the life of man is placed before us, and if we have no more than this, we have at any rate _something_ which may occupy our imaginations, and prevent them, as they otherwise would do, as, of old, men’s minds did, from leaping almost at a bound from the Creation to the Flood, and from the Flood to the time of Abraham.
