      “If we remove the shields, we discover, on each side of the body, a row of wart-like feet, from each of which project two bundles of spines of exquisite structure. The bundles, expanding on all sides, resemble so many sheaves of wheat, or you may more appropriately fancy you behold the armoury of some belligerent sea-fairy, with stacks of arms enough to accoutre a numerous host.

      “But, if you look closely at the weapons themselves, they rather resemble those which we are accustomed to wonder at in missionary museums—the arms of some ingenious but barbarous people from the South Sea Islands—than such as are used in civilised warfare. Here are long lances, made like scythe-blades, set on a staff, with a hook on the tip, as if to capture the fleeing foe, and bring him within reach of the blade. Among them are others of similar shape, but with the edge cut into delicate slanting notches, which run along the sides of the blade like those on the edge of our reaping-hooks.

      “These are chiefly the weapons of the lower bundle; those of the upper are still more imposing. The outermost are short curved clubs, armed with a row of shark’s teeth to make them more fatal; these surround a cluster of spears, the long heads of which are furnished with a double row of the same appendages, and lengthened scimitars, the curved edges of which are cut into teeth like a saw.

      “Though a stranger might think I had drawn copiously on my fancy for this description, I am sure, with your eye upon what is on the stage of the microscope at this moment, you will acknowledge that the resemblances are not at all forced or unnatural. To add to the effect, imagine that all these weapons are forged out of the clearest glass instead of steel; that the larger bundles may contain about fifty, and the smaller half as many each; that there are four bundles upon every segment, and that the body is composed of twenty-five such segments, and you will have a tolerable idea of the garniture and armature of this little worm, which grubs about in the mud at low-water mark.”

       PART OF WASP-STING. MAIN GAUCHE.

      Somewhere between the fifteenth and sixteenth centuries a sort of anomalous weapon was in use, namely, a dagger, with a number of very deep and bold barbs. It was not, however, employed for offence, but for defence, and was used in the “rapier and dagger” mode of fighting, when the dagger, which was held in the left hand, was employed to parry the thrusts of the rapier, which was held in the right. From the mode of holding it, the weapon was called “Main Gauche.”

      Sometimes the blade was quite plain, and, indeed, an ordinary dagger answered the purpose. But in most cases the Main Gauche was made for this special purpose, and was furnished either with strong diverging projections, or with a series of deep notches, so that the sword of the enemy might be caught in them and broken. In consequence of this use these notched or guarded weapons were also called by the name of Brise-épée, or Sword-breaker.

      The resemblance between this weapon and the blade of a wasp’s sting can be seen at a glance. There is another form of the Brise-épée which is so strangely like the cutting apparatus of one of the saw-flies, that an outline sketch of the one would answer very well for the other.

WAR AND HUNTING.

       PROJECTILE WEAPONS AND THE SHEATH.

      WE will now take some of the analogies between Projectile Weapons of Art and Nature, selecting those in which the propulsive power is air or gases within a tube. Whether the weapon be a blow-gun, an air-gun, or a firearm of any description, the principle is the same. We will take them in succession, choosing first those of the simplest and most primitive character.

      Taking ourselves as examples, and looking upon the toys of children as precursors of more important inventions, we find that the simplest and most primitive of projectiles is the Pea-shooter, so familiar to all boys.

      Insignificant as is the little tin tube, and small as are the missiles which are propelled through it, the blow which can be struck by a pea properly shot is no trifle. At college I have seen a night attack upon an undergraduate’s rooms successfully repelled by a pea-shooter made for the nonce of a glass tube, the owner of the rooms having a taste for chemicals, and possessing a fair stock of the usual apparatus. Though the assaulted rooms were on the top set, and the assailants began their storming approaches below, the peas were too much for the stones, taking stinging effect on the hands and faces, and preventing any good aim being taken at the windows. Only two panes of glass were broken through a siege that lasted for several hours.

      There is another toy which is a development of the pea-shooter, and carries a small clay bullet instead of a pea. When the tube is quite straight and the balls fit well, the force of this missile is very great, as it can be used for killing small birds. Indeed, such an instrument is largely employed by the native hunters in procuring humming-birds for the European market. These weapons are generally lined with metal in this country, but a simple bamboo tube is sufficient for the native hunters.

      A still further improvement occurs where the place of the bullet is taken by a small dart or arrow, which is usually made to fit the bore by having a tuft of wool, or some similar substance, at the butt. The arrow is aimed at a target, and the toy is popularly known as “Puff and Dart.”

      With us this apparatus is only a toy, but in several parts of the world it becomes a deadly weapon, namely, in Borneo and over a large part of tropical America. In both cases the arrows are poisoned, as has already been mentioned when treating of poisoned weapons.

      The first and best known of these weapons is the dreaded Sumpitan, or Blow-gun, of Borneo, the arrows of which are poisoned with the deadly juice of the upas-tree. Here I may as well mention that the scientific name of the upas-tree is Antiaris toxicaria. It belongs to a large group of plants, all of which have an abundance of milk-like and sometimes poisonous juice. We are most of us familiar with the old story of the upas-tree and its deadly power, and how the tree stood in a valley, in which nothing else could live, and that condemned criminals might compound for their inevitable fate by venturing into the valley of death and bringing back a flask of the dread poison. Even birds were supposed to be unable to fly over the valley, but to fall into it, being poisoned by the exhalations of the tree.

      Now, there is a saying that there is no smoke without fire, and though this account is evidently incredible, it is not altogether without foundation. In Java, as in many other parts of the world, there are low-lying places where carbonic acid gas exudes from the earth, and no living creature can exist in them. Even in this country scarcely a year passes without several deaths occurring from inhalation of the same fatal gas, which has collected in some disused excavation. That there is, therefore, a deadly valley in Java may be true enough, and it is also true that the juice of the upas-tree is poisonous when it mixes with the blood. But the two have no connection with each other, and, so far from the upas-tree poisoning the valley by its exhalations, it could not exist in such СКАЧАТЬ
