The advance of pre-historic study has been during the last ten years exceptionally rapid; and, considering upon how many subsidiary interests it touches, questions of politics, of social life, of religion almost, the science of pre-historic archæology might claim to stand in rivalry with geology as the favourite child of this century; as much a favourite of its declining years as geology was of its prime. But as yet, it will be confessed, we have little popular literature upon the subject, and that for want of it the general reader is left a good deal in arrear of the course of discovery. His ideas of nationalities and kindredship among peoples is, it may be guessed, still hazy. We still hear the Russians described as Tartars: and the notion that we English are descendants of the lost Israelitish tribes finds innumerable supporters. I am told that a society has been formed in London for collecting proofs of this more than Ovidian metamorphosis. The reason of this public indifference is very plain. Pre-historic science has not yet passed out of that early stage when workers are too busy in the various branches of the subject to spare much time for a comparison of the results of their labours; when, one may say, fresh contributions are pouring in too fast to be placed upon their proper shelves in the storehouse of our knowledge. In such a state of things the reader who is not a specialist is under peculiar disadvantages for a discovery of what has been done. He stands bewildered, like the sleeping partner in a firm, to whom no one--though he is after all the true beneficiary--explains the work which is passing before his eyes. It will not be thought a misplaced object to attempt some such explanation, and that is the object of the following chapters. And as at some great triumph of mechanism and science--a manufactory, an observatory, an ironclad,--a junior clerk or a young engineer is told off to accompany the intelligent visitor and explain the workings of the machinery; or as, if the simile serve better, in those cities which are sought for their treasures of art and antiquity, the lower class of the population become self-constituted into guides to beauties which they certainly neither helped to create nor keep alive; so this book offers itself to the interested student as a guide over some parts of the ground covered by pre-historic inquiry, without advancing pretensions to stand beside the works of specialists in that field. The peculiar objects kept in view have been, to put the reader in possession of (1) the general results up to this time attained, the chief additions which pre-historic science has made to the sum of our knowledge, even if this knowledge can be given only in rough outline; (2) the method or mechanism of the science, the way in which it pieces together its acquisitions, and argues upon the facts it has ascertained; and (3) to put this information in a form which might be attractive and suitable to the general reader.
