33 By permission of the author, the translator adds the following quotation from Taylor’s “Origin of the Aryans,” p. 17, which is referred to by Professor Huxley in his paper on the Aryan question in the _Nineteenth Century_ for November, 1890. Taylor says: “It is now contended that there is no such thing as an Aryan race in the same sense that there is an Aryan language, and the question of late so frequently discussed as to the origin of the Aryans can only mean, if it means anything, a discussion of the ethnic affinities of those numerous races which have acquired Aryan speech; with the further question, which is perhaps insoluble, among which of these races did Aryan speech arise and where was the cradle of that race?” 34 This poet is one of those whose work is to be found in the so-called “Black Book of Caermarthen.” See also “The Four Ancient Books of Wales, Containing the Cymric Poems Attributed to the Bards of the Sixth Century.” Edinburgh, 1868. CHAPTER VI. Industry, Commerce, and Social Organization; Fights, Wounds and Trepanation. When we consider the discoveries connected with the Stone age as a whole, we are struck with the immense numbers of weapons of every kind and of every variety of form found in different regions of the globe. The Roman domination extended over a great part of the Old World, and it lasted for many centuries. Everywhere this people, illustrious amongst the nations, has left tokens of its power and of its industry. Roman weapons, jewelry, and coins occupy considerable spaces in our museums; but numerous as are these relics of the Romans, they are far inferior in number to the objects dating from prehistoric times, and flints worked by the hand of man have been picked up by thousands in the last few years, forming incontestable witnesses of the rapid growth of a large population. One important point remains obscure. Schmerling has excavated fifty caves in Belgium, and only found human relics in two or three of them; and of six hundred explored by Lund in Brazil, only six contained human bones. Similar results were obtained in the excavations of the mounds of North America, as well as in the caves of France. M. Hamy, in a book published a few years ago, only mentions twelve finds of human bones, which could, without any doubt, be dated from Palæolithic times. True, this number has been added to by recent discoveries, but it is still quite insignificant. It is the same thing with the kitchen-middings and the Lake settlements. This paucity of actual human remains forms a gap in the evidence relating to prehistoric man, which disturbances and displacements do not sufficiently account for, and to which we shall refer again when speaking of prehistoric tombs.
