classic amentum, a thong attached to the middle of the shaft of the javelin to throw it with. The highest people known to have used the spear-thrower proper were the nations of Mexico and Central America. Its existence among them is vouched for by representations in the mythological pictures, by its Mexican name 'atlatl,' and by a beautifully artistic specimen of the thing itself in the Christy Museum; but we do not hear of it as in practical use after the Spanish Conquest. In fact the history of the instrument seems in absolute opposition to the degradation-theory, representing as it does an invention belonging to the lower civilization, and scarcely able to survive beyond. Nearly the same may be said of the blow-tube, which as a serious weapon scarcely ranges above rude tribes of the East Indies and South America, though kept up in sport at higher levels. The Australian boomerang has been claimed as derived from some hypothetical high culture, whereas the transition-stages through which it is connected with the club are to be observed in its own country, while no civilized race possesses the weapon.
The use of spring traps of boughs, of switches to fillip small missiles with, and of the remarkable darts of the Pelew Islands, bent and made to fly by their own spring, indicate inventions which may have led to that of the bow, while the arrow is a miniature form of the javelin. The practice of poisoning arrows, after the manner of stings and serpents' fangs, is no civilized device, but a characteristic of lower life, which is generally discarded even at the barbaric stage. The art of narcotizing fish, remembered but not approved by high civilization, belongs to many savage tribes, who might easily discover it in any forest pool where a suitable plant had fallen in. The art of setting fences to catch fish at the ebb of the tide, so common among the lower races, is a simple device for assisting nature quite likely to occur to the savage, in whom sharp hunger is no mean ally of dull wit. Thus it is with other arts. Fire-making, cooking, pottery, the textile arts, are to be traced along lines of
