Pitfalls are often dug in great numbers, near frequented watering-places, to which numerous intersecting paths lead: by stopping up particular paths, the pitfalls can be brought separately into use; therefore, those pitfalls need never be employed in which animals have been freshly killed, and where the smell of blood would scare the game. It is difficult to prevent the covers of pitfalls becoming hollow: the only way is to build the roofs in somewhat of an arch, so as to allow for subsidence. If a herd of animals be driven over pitfalls, some are sure to be pushed in, as the crush makes it impossible for the beasts, however wary, to pick their way.
Uganda Thorn-wreath.--Captain Grant found a very ingenious contrivance in use in Uganda, in Africa. Two small Stout hoops of equal diameter, made of wood fully an inch in thickness, were lashed one above the other; long acacia thorns were interposed, forming the spokes of a wheel of which the hoops formed the rim. The bases of the thorns were nipped between the hoops; and their points radiated towards the centre. A great many thorns were used, so that the appearance was that of a wheel without a nave, whose spokes were so close together that they touched each other, and, as thorns taper from base to point, the spokes touched one another along their whole length, from circumference to centre. This apparatus is always made with great neatness. It is laid over a hole 18 inches deep, dug in the beast's path, and the noose of a cord, of which the other end is secured to a log, is laid closely within the upper hoop. When the beast treads on the apparatus, he crashes through the thorns, but, on withdrawing his foot from the hole, the wreath clings to his fetlock like a ruff, and prevents the noose from slipping off. Thus there is time for the noose to become firmly jammed during the struggles of the beast. Of course, the trapper artfully bushes the path, so as to induce him to step full upon the trap. He sets a great many of them, and they require no looking after. The diameter of the hoops is made proportionate to the size of the beast for which they are intended. Six inches interior diameter was the size used for buffalo and hartebeest.
Traps.--Steel traps should never be tied fast, or the captured animal may struggle loose, or even gnaw off his leg. It is best to cut small bushes, and merely to secure the traps to their cut ends. Steel traps are of but little use to a traveller.
Hawks are trapped by selecting a bare tree, that stands in an open space: its top is sawn off level, and a trap is put upon it: the bait is laid somewhere near, on the ground: the bird is sure to visit the pole, either before or after he has fed.
Poison.--Savages frequently poison the water of drinking-places, and follow, capture, and eat the poisoned animals. Nux vomica or strychnine is a very dangerous poison to use, but it affords the best means of ridding a neighbourhood of noxious beasts and birds: if employed to kill beasts, put it in the belly; if, birds, in the eye, of the bait. Meat for killing Beasts should be set after nightfall; else the crows and other birds will be sure to find it out, and eat it up before the beasts have time to discover it. It would be unsafe to eat an animal killed with strychnine, on account of the deadliness of the poison.
The Swedes put fulminating-powder in a raw shankbone, and throw it down to the wolves; when one of these gnaws and crunches it, it blows his head to atoms.
Poisoned Bullets.--I take the following extract from 'Galignani's Messenger:'--"A new method of catching whales is now being tried with considerable success, science having contributed to its discovery. Our readers are well aware of the deadly effects of the Indian poison called wurare, or woorali, concerning which we have often had occasion to record the most interesting experiments, especially in mentioning the attempts made to use it as a specific for lockjaw, its peculiar action consisting in relaxing the muscular system. Strychnine is a poison producing the contrary effect, the excessive contraction of that system, or, in other words, tetanus, or lockjaw. It is a curious fact that by the conjunction of these two agents, so diametrically opposite in their effects, a poison is obtained that will kill almost instantly if only administered in the dose of half a milligramme per kilogramme of the animal to be subjected to its action, provided its weight do not exceed ten kilogrammes. If larger, the dose must be proportionally increased. M. Thiercelin, the inventor of this poison, composes it by mixing a salt of strychnine with one-twentieth of woorali. To apply it to whale fishing, he makes the compound up into cartridges of thirty grammes (an ounce) each, which is enough to kill an animal of 60,000 kilogrammes weight. Each cartridge is imbedded in the gunpowder contained in an explosive shell which is fired off on the whale. In a late whaling voyage ten whales received such missiles, and all died within from four to eighteen minutes after the infliction of the wound. Out of these ten whales, six were cut up for their blubber and whalebone. Their remains were handled by careless men, who frequently had scratches and sores on their skin, and yet not one of them suffered the slightest injury, a circumstance which Shows that the poison cannot be transmitted from the fish to the men. Its poisonous action on the whale is, however, so great that practically the dose will have to be diminished, so that the death of the creature may not be so sudden. We should not forget to state that two out of the ten whales above mentioned were lost by one of the many accidents incident to whaling, and that two others were of a kind that is not worth fishing for."
Poisoned Arrows.--Arrows are most readily poisoned by steeping a thread in the juice, and wrapping it round the barbs. Serpents' venom may always be used with effect.
Bird-lime can be made from the middle bark of most parasitic plants, that is to say, those that grow like mistletoe, out of the boughs of other trees. Holly and young elder shoots also afford it. The bark is boiled for seven or eight hours, till quite soft, and is then drained of its water and laid in heaps, in pits dug in the ground, where it is covered with stones and left for two or three weeks to ferment; but less time is required, if the weather be hot. It is watered from time to time, if necessary. In this way, it passes into a mucilaginous state; and is then pounded into a paste, washed in running water, and kneaded till it is free from dirt and chips. Lastly, it is left for four or five days in earthen vessels, to ferment and purify itself, when it becomes fit for use. It ought to be greenish, sour, gluey, stringy, and sticky. It becomes brittle when dry, and may be powdered; but, on being wetted, it becomes sticky again. (Ure's Dictionary.)
Vast flocks of birds frequent the scattered watering-places of dry countries at nightfall and at daybreak: by liming the sedges and bushes that grow about them, numbers of birds could be caught.
