Nature's Teachings. John George Wood

a twig. It is the work of one of the House-builder Moths of the West Indies, and forms a sort of house in which the caterpillar can rest securely. It is built of bits of twigs and thorns, the latter being disposed so that their points are outwards, much after the fashion of a hedgehog’s spines.

      I possess many specimens of Tree-caddis, evidently belonging to several species, and in all of them the principle is the same, i.e. a number of spikes set with their ends outwards in order to defend a central position.

      Sometimes these spikes are left exposed, as shown in the illustration, and sometimes they are covered with a slight but strong web. The principle, however, is the same in all.

      Now I shall have to use two very long words, and much against my will. I very much fear that, if most of my readers were to hear any one speak of the “repagula of Ascalaphus,” they would not be much the wiser. And yet there are no other words that can be used.

      In the first place, Ascalaphus is a name belonging to a genus of Ant-lions, remarkable for having straight, knobbed antennæ, very much like those of a butterfly. This insect deposits its eggs in a double row on twigs, and then defends them with a series of natural ranjows, set in circular rows, and supposed to be without analogies in the animal creation. They are transparent, reddish, and “are expelled by the female with as much care as though they were real eggs, and are so placed that nothing can approach the brood; nor can the young ramble abroad until they have acquired strength to resist the ants and other insect enemies.”

      The word “repagulum,” by the way, signifies a bar or barrier. A turnpike gate when closed would be a repagulum, and so would a chevaux-de-frise.

Tearing Weapons

      We have already had examples of weapons, like the Club, which bruise; of weapons, like the Spear and Dagger, which pierce; and of weapons, like the Sword, which cut. We now come to a totally distinct set of weapons, those which wound by tearing, and not by any of the preceding modes.

      In civilised warfare we have long abandoned such weapons, as belonging to a barbarous age, but they are even yet employed in some parts of the world.

      The accompanying illustration shows three examples of such weapons. One is the celebrated Tiger-claw of India, known by the native name of Wag-nuk. It is about two inches and a half in length, and is made to fit on the hand. The first and fourth fingers are passed through the rings, and the curved claws are then within the hand, and hidden by the fingers. The mode of employing this treacherous weapon was by engaging a foe in conversation, pretending to be very friendly, and then ripping up his stomach with an upward blow of the right hand.

      It is comparatively a modern weapon, having been invented about two hundred years ago. A Hindoo, named Sewaja, was the inventor, and by means of the Wag-nuk he committed many murders unsuspected, the wounds being exactly like those which are made by the claw of the tiger. Sometimes there were four claws instead of three, as is the case with a specimen one in the Meyrick collection.

      Perhaps the reader may be aware that the Transatlantic “knuckle-duster” is fitted on the hand in the same manner, only its object is to strike a heavy blow, and not to tear. History repeats itself, and the large and clumsy “cestus” of the ancient athlete is reproduced in the small but scarcely less formidable “knuckle-duster” of the modern rowdy.

      The figures are remarkable, one representing the remaining epoch of chivalry, and the other that of barbarism. The upper figure shows a curious Gauntlet of the Middle Ages, in which the hand is not only defended by steel plates, but is also rendered an offensive weapon by the addition of four sharp spikes set just at the junction of the fingers with the hand. As long as the fingers are extended the spikes lie parallel with them, and are as harmless as a cat’s claws in their sheaths. But when the fingers are closed, as shown in the illustration, the spikes come into use, and can be made into a formidable weapon of offence, just as are the cat’s claws when protruded.

      Below the gauntlet of civilised warfare is one of savage war, which has for many years been discontinued, partly on account of the introduction of firearms, and partly owing to the superficial coating of civilisation which is so easily adopted by the singular varieties of the human race which populate the isles where this remarkable weapon was once worn. The figure is taken from a specimen in the United Service Museum.

      It is a Gauntlet, having at one end a band through which the whole hand is passed, and at the other three loops for the fingers, just like those of the Wag-nuk, which has already been described. The body of the weapon is made of cocoa-nut fibre, and upon it are strung six rows of sharks’ teeth, the tips all pointing backwards. It is a Samoan weapon, some of the most renowned warriors never using club nor spear, but trusting entirely to their terrible gauntlets. With these they struck right and left, dashing beneath the clubs and spears of their enemies, and always trying to rip up their stomachs, just as is done with the Wag-nuk. In order to guard against this weapon, the Samoan warrior wears a belt of cocoa-nut fibre some eight inches wide, and thick enough to defy the best gauntlet that could be made.

      One celebrated Samoan warrior, a man of gigantic stature and strength, was addicted to the amusement of seizing his enemies with the shark-tooth gauntlets, breaking their backs across his knee, throwing them down, and going off after another victim.

      On the left hand of the illustration is seen the hind-foot of the Tiger. I have chosen the hind-foot for two reasons: firstly, because the fore-foot has already been figured; and secondly, because the hind-foot is used for tearing open the abdomen of the prey. Any one who has played with a kitten has noticed how the animal throws itself on its back, clasps the wrist with its fore-paws, and kicks vigorously with its hind-legs. It does not mean to hurt its playfellow, but the hand does not easily escape without sundry scratches.

      Child’s play though it may be in the kitten, it is no play at all with the tiger, or even the leopard, for either of these animals, when hard pressed, will throw itself on its back, clasp the foe in its fore-paws, and with the talons of the hind-feet tear him to pieces.

The Hook

      HAVING now seen that the rod and line of anglers have their prototypes in Nature, we will proceed to the hook, by which the fish are secured.

      The two figures on the right hand of the accompanying illustration represent hooks which are familiar to every angler. The lower is the ordinary fish-hook, which can be used in so many ways. Generally it is employed singly, being fastened to the end of a line, and armed with a bait, either real or artificial. Sometimes, however, these hooks are whipped together, back to back, three or even four being so employed, and thus forming a combination of the hook and grapnel, and rendering the escape of a fish almost impossible.

      Above it is a double hook, such as is used in “trolling” for pike, and with the use of which many of my readers are probably acquainted.

      The third is a singularly ingenious hook made by the natives of British Columbia. It is almost entirely made of wood, with the exception of the barb, which is of bone. This, as the reader will see, is
