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.

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 an atmosphere.
Now for the Sumpitan and the arrows. The former is a tube, some seven feet in length, with a bore of about half an inch in diameter, and often elaborately inlaid with metal. I have one in which the whole of the mouthpiece is brass, and the other end of the weapon has been fitted with a large spear-head, exactly on the principle of the bayonet.
The arrows are very slight, and, in order to make them fit the tube, are furnished at their bases with a conical piece of soft wood. In themselves they would be almost useless as weapons, but when the poison with which their points are armed is fresh, these tiny arrows, of which sixty or seventy are but an ordinary handful, carry death in their points. Though they have no great range, they are projected with much force, and with such rapidity that they cannot be avoided, their slender shafts being almost invisible as they pass through the air.
The second weapon is the still more dangerous blow-gun of tropical America, called Zarabatana, or Pucunha, according to the locality. Some of these tubes measure more than eleven feet in length, and through them the arrow can be propelled with wonderful force. I have often sent an arrow to a distance of a hundred yards, and with a good aim.
A native, however, can send it much farther, knack, and not mere capacity of lung, supplying the propelling power, just as it is with the pea-shooter. When the arrow is properly blown through the zarabatana a sharp “pop” ought to be heard, like the sound produced by a finger forced into a thimble and quickly withdrawn, or a cork drawn from a bottle.
As to seeing the diminutive arrow in its flight, it is out of the question, and no agility can be of the least use in avoiding it. One of my friends, a peculiarly sharp-sighted officer of artillery, has often tested this point, and although there was but one arrow to watch, and it was blown in the open air, he could not see it until it either struck or passed him (of course the poisoned end was cut off). What, then, would be the result of a number of these deadly missiles hurled out of a dense bush may easily be imagined.
An account of the poison with which these arrows are armed will be found on p. 64.
The reader will please to remember that in all these cases the missile is propelled by air which is compressed by the aid of the lungs, and forced into the tube behind the bullet or arrow. Now, the Air-gun, which really can be made a formidable weapon, is constructed on exactly the same principle as the pea-shooter and the blow-guns, except that the air is compressed by the human arm instead of the human lungs. There are various modifications of this weapon, but in all of them air is driven into a strong chamber by means of a forcing syringe, and is released by the pull of the trigger, so as to drive out the missile which has been placed in the barrel.
It is worthy of notice that the term “noiselessly destructive” weapon, as applied to the air-gun, is entirely false. I have already mentioned that with the blow-gun of tropical America a definite explosion accompanies the flight of each arrow. The same result occurs with the air-gun, the loudness of the report being in exact proportion to the force of the air, each successive report becoming slighter and the
