black earth. This seems at present the only intelligible history of this curious cave and others resembling it; though, when we consider the imperfection of the results obtained even by a large amount of labour, and the difficult and confused character of the deposits in this and similar caves, too much value should not be attached to such histories, which may at any time be contradicted or modified by new facts or different explanations of those already known. The time involved depends very much, as already stated, on the question whether we regard the Post-glacial subsidence and re-elevation as somewhat sudden, or as occupying long ages at the slow rate at which some parts of our continents are now rising or sinking.[AT] [AT] Another element in this is also the question raised by Dawkins, Geikie, and others as to subdivisions of the Post-glacial period and intermissions of the Glacial cold. After careful consideration of these views, however, I cannot consider them as of much importance. Such are the glimpses, obscure though stimulating to the imagination, which geology can give of the circumstances attending the appearance of man in Western Europe. How far we are from being able to account for his origin, or to give its circumstances and relative dates for the whole world, the reader will readily understand. Still it is something to know that there is an intelligible meeting-place of the later geological ages and the age of man, and that it is one inviting to many and hopeful researches. It is curious also to find that the few monuments disinterred by geology, the antediluvian record of Holy Scripture, and the golden age of heathen tradition, seem alike to point to similar physical conditions, and to that simple state of the arts of life in which "gold and wampum and flint stones"[AU] constituted the chief material treasures of the earliest tribes of men. They also point to the immeasurable elevation, then as now, of man over his brute rivals for the dominion of the earth. To the naturalist this subject opens up most inviting yet most difficult paths of research, to be entered on with caution and reverence, rather then in the bold and dashing spirit of many modern attempts. The Christian, on his part, may feel satisfied that the scattered monumental relics of the caves and gravels will tell no story very different from that which he has long believed on other evidence, nor anything inconsistent with those views of man's heavenly origin and destiny which have been the most precious inheritance of the greatest and best minds of every age, from that early pre-historic period when men, "palaeolithic" men, no doubt, began to "invoke the name of Jehovah," the coming Saviour, down to those times when life and immortality are brought to light, for all who will see, by the Saviour already come. [AU] So I read the "gold, bedolah, and shoham" of the description of Eden in Genesis ii.--the oldest literary record of the stone age.
