Bows, with arrows four or five feet long, are used to kill the larger animals. The arrows are made of a yellow reed without joint or knot. A piece of hard wood is inserted into the end, and in this a square hole is made, tightly bound round with cotton to keep it from splitting. Into this square hole a spike is fitted, and dipped in the poison, while at the butt-end a couple of feathers are fastened to steady it in its flight. The hunter carries a number of these poisoned spikes. As the spike easily breaks off, or slips out when the animal is wounded, he recovers his shaft, into which he can easily refit another spike. The spikes are cut half through, to facilitate their breaking off. TIMBO. The Indian has also discovered the means of poisoning the fish of the lakes and pools, as well as the birds of the air. He extracts the poison from a certain liana--the paullinia pinnata--which he calls timbo. To do so, he collects a few pieces, about a yard long, and mashes and soaks them in water, which soon becomes discoloured with the milky poisonous juice of the plant. This he carries in a calabash, and pours out on the water. In about half an hour, all the smaller fish, over a wider space than that which he has sprinkled with the juice, rise to the surface, floating on their sides, with their gills wide open. So powerful is its nature, that but a slight quantity appeal's sufficient to stupify them. Some time afterwards the larger fish appear; and even for twenty-four hours afterwards a number rise floating dead on the surface. The fish are evidently suffocated by the poison.
