In either of these cases the fallen knight was not much the worse, until a weapon called the “Misericorde,” or dagger of mercy, was invented. This was a poniard with a very slender and very sharp blade, so constructed that it could be driven between the joints of the armour, and thus inflict a mortal wound. The Misericorde, however, was baffled by the use of chain or scale armour under the plate-mail, and then the only way of getting at the fallen knight was by breaking up the armour with hammers which were made for this express purpose. Perhaps the reader may wonder that any one should lie quietly and allow himself to be so badly treated. The very strength of the armour, however, which rendered its wearer unassailable by ordinary weapons, involved so much weight, that when a knight had fallen, it was impossible for him to rise, much less to mount a horse, without help. Moreover, the first blow of a weighty hammer on the helmet would, although it could not kill the wearer, cause such a jar to his brain as partially, if not wholly, to stun him. The rapidly increasing power of firearms soon caused armour to be laid aside, and now the only remains of it are to be found in the helmets and cuirasses worn by our dragoons. * * * * * THERE are few parts of the world where armour of some sort is not used. Putting aside civilised or semi-civilised nations, we find that in most cases, wherever there is war, there is armour of some kind. Sometimes it is movable, and in that case is called a shield. The most singular shields that I know are those made by the Australians, which are so shaped that no one who did not know their use would take them for shields. They are about three feet long, four inches wide at the back, six inches or so thick in the middle, tapering towards the ends, and coming to an edge in front. They are held by the centre with one hand, so that they can be rapidly twisted from side to side, and so serve to parry the spear or stop the boomerang. The weight of the shield enables it to withstand the shock of the boomerang, which whirls through the air with terrific force. Several warlike savage tribes have, however, no armour of any kind, such as the New Zealanders, the Samoans, and the Fijians. Sometimes the armour is affixed to the body, and of such protection many examples are to be found in various museums, among which the Christy collection is pre-eminent. Among the Polynesians cocoa-nut fibre was at one time employed as the material for armour. It was twisted into small cords, and with these a sort of armour was constructed, quite strong enough to resist any weapon that an enemy of their own kind could bring against them. Sometimes this armour was merely a belt wide enough to protect the abdomen, but sometimes the whole body was defended, from the neck to the hips.
