Their arms consist chiefly of blow-guns or _bodoquedas_, although at present shot-guns and _machetes_ are beginning to be introduced among them. These blow-guns are not manufactured by the Incas, but are bought by them from the Indians of Mocoa, who obtain them from the Cioni Indians of the Upper Putumayo. The Cionis, in turn, are supplied with them by the Indians of the River Napo, who are the original manufacturers. This celebrated weapon is a hollow, tapering pole, from two to four metres long, pierced longitudinally by a hole some three-sixteenths of an inch in diameter. The outside surface of the pole is wound around with thin strips of tough bark, over which is applied a smooth, black coating of gum-resin from the _arbol del lacre_, or sealing-wax tree, while the thicker end terminates in a mouthpiece, into which a small arrow, some twenty centimetres long and tipped with a little cotton instead of a feather, is introduced. The mouth is then applied to the mouthpiece, and with the breath the little arrow is shot out with great force to a distance of from thirty to forty metres. These arrows, apparently so insignificant, are in reality awful in their effects, for their points are tipped with the celebrated _curaré_, made from the _Strychnos castelmoeana_, called by them _ramu_, and from the _Cocculus toxicoferus_, known to these aborigines as _pani_. The points are often cut, so as to break off after penetrating the skin and stay in the wound. A puncture of the skin by one of these arrows causes death within a minute, for I have seen a large dog struck by one of these little missiles drop dead before he could run five metres. Like the _bodoqueda_ itself, these little arrows reach the Incas only after passing through the hands of several tribes, and are generally carried in a small bamboo quiver, to which is tied a little gourd filled with cotton. It is interesting to note that although the _curaré_ with which the arrows are tipped is a deadly poison, it has absolutely no injurious effect upon the game killed by it. In many respects this weapon is superior to the shot-gun, but its great advantage is its noiselessness. Thus, a hunter can kill bird after bird without fear of their becoming alarmed and flying away. The Indians can shoot very accurately with the _bodoqueda_ up to about thirty metres.
