inventor--such is the way of the crowd; but, as it duly pocketed the invention, we have perhaps no special cause to complain. By way of appreciating the conditions prevailing in the Later Neolithic Age, let us consider in turn the Lake-dwellers of Switzerland and the Dolmen-builders of our Western coast-lands. I was privileged to assist, on the shore of the Lake of Neuchatel, in the excavation of a site where one Neolithic village of pile-dwellings had evidently been destroyed by fire, and at some later date, just falling within the Stone Age, had been replaced by another. Here we had lighted on a crucial instance of the march of cultural progress. The very piles testified to it, those of the older settlement being ill-assorted and slight, whereas the later structure was regularly built and heavily timbered. It was clear, too, that the first set of inhabitants had lived narrow lives. All their worldly goods were derived from strictly local sources. On the other hand, their successors wore shells from the Mediterranean and amber beads from the Baltic among their numerous decorations; while for their flint they actually went as far afield as Grand Pressigny in West-Central France, the mines of which provided the butter-like nodules that represented the _ne plus ultra_ of Neolithic luxury. Commerce must have been decidedly flourishing in those days. No longer was it a case of the so-called 'silent trade', which the furtive savage prosecutes with fear and trembling, placing, let us say, a lump of venison on a rock in the stream dividing his haunts from those of his dangerous neighbours, and stealing back later on to see if the red ochre for which he pines has been deposited in return on the primitive counter. The Neolithic trader, on the other side, must have pushed the science of barter to the uttermost limits short of the invention of a circulating medium, if indeed some crude form of currency was not already in vogue.
