A weapon formed on exactly the same principle was used in the fifteenth and sixteenth centuries, and was employed for dragging knights off their horses. It was of steel instead of wood, and the place of the thorns was taken by two movable barbs, working on hinges, and kept open by springs. When a thrust was made at the knight’s neck the barbs gave way, so as to allow the prongs to envelop the throat, and they then sprang back again, preventing the horseman from disengaging himself. This weapon is technically named a “catchpoll.” An illustration of one of these weapons will be given on another page. The right-hand central figure is an arrow from Western Africa. In a previous illustration (page 65) a head of one of these arrows is given on rather a larger scale, so as to show the very peculiar barbs. These are of such a nature that when they have well sunk into the body they cannot be withdrawn, but must be pushed through, and drawn out on the opposite side. This is drawn from one of my own specimens. In some cases, with an almost diabolical ingenuity, the native arrow-maker has set on a couple of similar barbs, directed towards the point, so that the weapon can neither be pushed through nor drawn back. One of these arrows is shown in the illustration, but, for want of space, the artist has placed the opposing barbs too near each other. In some parts of Southern Africa a similar weapon was used for securing a prisoner, the barbed point being thrust down his throat and left there. If it were pushed through the neck it killed him on the spot, and if it remained in the wound the man could not eat nor drink, and the best thing for him was to die as soon as he could. With similar ingenuity, the Tongans and Samoans made their war-spears with eight or nine barbs, and, before going into action, used to cut the wood almost through between each barb, so that when the body was pierced, the head, with several of the barbs, was sure to break off and leave a large portion in the wound. In Mariner’s well-known book there is an admirable account of the mode employed by a native surgeon for extracting one of these spear-heads. So common was this weapon that every Tongan gentleman carried a many-barbed spear about five feet long, and used it either as a walking-stick or a weapon. It is needless to say that this spear is almost an exact copy of the tail-bone of the Stingray. A dagger made of this bone was used in the Pelew Islands in 1780, but seemed to be rather scarce. The left-hand central figure is a Fijian fish-spear of four points, and the last figure on the right hand represents a large four-pronged spear of Borneo. Both these weapons are in my collection. * * * * *
