Note 13 — Chapter I · The Stone Age: its Duration and its Place in Time.

It was in 1826 that Boucher de Perthes first published his opinion; but it was not until 1816 and 1847 that he announced his discovery at Menchecourt, near Abbeville, and at Moulin-Quignon and Saint Acheul, in the alluvial deposits of the Somme, of flints shaped into the form of hatchets associated with the remains of extinct animals such as the mammoth, the cave lion, the Rhinoceros incisivus, the hippopotamus, and other animals whose presence in France is not alluded to either in history or tradition. The uniformity of shape, the marks of repeated chipping, and the sharp edges so noticeable in the greater number of these hatchets, cannot be sufficiently accounted for either by the action of water, or the rubbing against each other of the stones, still less ply the mechanical work of glaciers. We must therefore recognize in them the results of some deliberate action and of an intelligent will, such as is possessed by man, and by man alone. Professor Ramsay13 tells us that, after twenty years’ experience in examining stones in their natural condition and others fashioned by the hand of man, he has no hesitation in pronouncing the flints and hatchets of Amiens and Abbeville as decidedly works of art as the knives of Sheffield. The deposits in which they were found showed no sins of having been disturbed; so that we may confidently conclude that the men who worked these flints lived where the banks of the Somme now are, when these deposits were in course of being laid down, and that he was the contemporary of the animals whose bones lay side by side with the products of his industry.
