He had, however, the hand, the most perfect of all prehensile contrivances, and Necessity compelled him to use it. The stone, his first ‘weapon,’ properly so called, would serve him in two ways—as a missile, and as a percussive instrument. Our savage progenitor, who in days long before the dawn of history, contracted the extensor and relaxed the flexor muscles of his arm when flinging into air what he picked up from the ground, was unconsciously lengthening his reach and taking the first step in the art and science of ballistics. His descendants would acquire extraordinary skill in stone-throwing, and universal practice would again make perfect. Diodorus of Sicily (B.C. 44),[50] who so admirably copied Herodotus, says that the Libyans ‘use neither Swords, spears, nor other weapons; but only three darts and stones in certain leather budgets, wherewith they fight in pursuing and retreating.’ The Wánshi (Guanches) Libyan or Berber peoples of the Canarian Archipelago, according to Cà da Mosto (A.D. 1505), confirmed by many, including George Glas,[51] were expert stone-throwers. They fought their duels ‘in the public place, where the combatants mounted upon two stones placed at the opposite sides of it, each stone being flat at top and about half a yard in diameter. On these they stood fast without moving their feet, till each had thrown three round stones at his antagonist. Though they were good marksmen, yet they generally avoided those missive weapons by the agile writhing of their bodies. Then arming themselves with sharp flints (obsidian?) in their left hands, and cudgels or clubs in their right, they fell on, beating and cutting each other till they were tired.’ An instance is mentioned in which a Guanche brought down with a single throw a large palm-frond, whose mid-rib was capable of resisting the stroke of an axe. Kolben, who wrote about a century and a half ago, gives the following account of the ape-like gestures of the Khoi-Khoi or Hottentots[52]:—‘The most surprising strokes of their dexterity are seen in their throwing of a stone. They hit a mark to a miracle of exactness, though it be a hundred paces distant and no bigger than a halfpenny. I have beheld them at this exercise with the highest pleasure and astonishment, and was never weary of the spectacle. I still expected after repeated successes, that the stone would err; but I expected in vain. Still went the stone right to the mark, and my pleasure and astonishment were redoubled. You could imagine that the stone was not destined to err, or that you were not destined to see it. But a Hottentot’s unerring hand in this exercise is not the only wonder of the scene; you would be equally struck perhaps with the manner in which he takes his aim. He stands, not still with a lift-up arm and a steady staring eye upon the mark, as we do; but is in constant motion, skipping from one side to another, suddenly stooping, suddenly rising; now bending on this side,
