flies (Bombylius). These flies do not suck blood like the Mosquito, the Flea, and the Gad-fly, but they use the long proboscis for sucking the sweet juices out of flowers, and in consequence it is nearly of the same form as if it were meant for sucking blood. Indeed, there are some insects which do not seem to care very much whether the juice which they suck is animal or vegetable.

       8 CLAW.—SHEATH OPENING ALONG THE CURVED BACK. INDIAN TULWAR.—SHEATH OPENING ALONG THE CURVED BACK.

      On the right hand of the illustration is seen an Indian sword, or “Tulwar,” drawn from one of my own specimens. I have selected this example on account of the structure of the sheath. It is evident, from the form of the blade, that the sword cannot be sheathed point foremost, and that therefore some other plan must be used. In this weapon the sheath is left open on one side, the two portions being held together by the straps which are shown in the figure. Of course there is loss of time in sheathing and drawing such a sword, but the peculiar shape of the blade entails a necessity for a special scabbard.

      On the other side is shown one of the fore-claws of a cat, which, as we all know, can be drawn back into its simple sheath between the toes, when it is not in use. This sheath is exactly the same in principle as that of the Indian tulwar, and any one can examine it by looking at the foot of a good-tempered cat. I have done so even with a chetah, which is not a subject that would generally be chosen for such a purpose.

      On the next illustration is shown an ordinary Lancet, in which the blade is guarded between a double sheath, the two halves and the blade itself working upon a common pivot. As for the ordinary sword and dagger sheaths, it is not worth while to figure them.

      Turning to the opposite side of the illustration, we shall see a few of the innumerable examples in which the principle of the sheath was carried out in Nature long before man came on the earth.

      The reader should compare this figure with the side view of the Gnat’s lancets given on p. 81.

       LANCETS OF TABANUS CLOSED. LANCETS OF MOSQUITO PARTLY OPEN. SURGEON’S LANCET PARTLY OPEN.

      They represent the cutting and piercing instruments of several insects, all of which are very complicated, and are sheathed after the manner of the lancet. Indeed, they are popularly known as “mouth-lancets,” and with reason, as the reader may see by reference to the illustration.

      On the extreme left are shown the head and closed lancets of a foreign Gad-fly, the lancets being all in their sheaths, and showing the character of the weapon which enables a small fly to be master, or rather mistress, of the forest. I say mistress, because in all these cases it is the female alone that possesses these instruments of torture.

      Next it is a magnified representation of the lancets of the common Mosquito, as seen from above, both lancets being removed from their sheaths and separated.

The Net.

       Table of Contents

      ALTHOUGH the Net is but seldom employed for the purposes of general warfare, it was once largely used in individual combats, of which we will presently treat. In hunting, however, especially in fishing, the Net has been in constant use, and is equally valued by savages and the most civilised nations.

      To begin with the fisheries. Even among ourselves there are so many varieties of fishing-nets that even to enumerate them would be a work of time. However, they are all based on one of two principles, i.e. the nets which are set and the nets which are thrown.

      We will begin with the first.

      On the right hand of the illustration, and at the bottom, may be seen a common Seine-net being “shot” in the sea. This form of net is very long in proportion to its width, some of these nets being several miles long. The upper edge of the net is furnished with a series of cork bungs, which maintain it on the surface, while the lower edge has a corresponding set of weights, which keep the net extended like a wall of meshes. Any fish which come against this wall are, of course, arrested, and are generally caught by the gill-covers in their vain attempts to force themselves through the meshes.

      We may see representations of fishing with the seine-net in the sculptures and paintings of Egypt and Assyria; and in the Berlin Museum there is a part of an Egyptian seine-net with the leads still upon the lower edge, and the upper edge bearing a number of large pieces of wood, which acted as buoys, and served the same purpose as our corks.

       SPIDER-WEB. HUNTING-NET. THE SEINE-NET.

      In hunting, this plan has been adopted for many centuries, the upper edge of the net being supported on poles, and the lower fastened to the ground in such a manner as to leave the net hanging in loose folds. While this part of the business is being completed by the servants, the hunters are forming a large semicircle, in which they enclose a number of wild beasts, which they drive into the nets or “toils” by gradually contracting the semicircle. The ancient sculptures give us accounts of nets used in exactly this manner. There are represented the nets rolled up ready for use, and being carried on the shoulders of several attendants, who are bearing them to the field. Then there are the nets set up on their poles, and having enclosed within them a number of wild animals, such as boars and deer.

      In various parts of India, hunting with the net is one of the chief amusements of their principal men, and the variety of game driven into the toils is really surprising, and affords a magnificent sight to those who view it for the first time. Even the tiger himself cannot leap over the nets because they are so high, nor force his way through them, because their folds hang so lightly that they offer no resistance to his efforts.

      A very simple net on similar principles is used for catching elephants. It is formed of the long creeping plants that fling themselves in tangled masses from tree to tree. These creepers are carefully twisted into a net-like form, without being removed from the trees, and when a sufficient space has been enclosed the elephants are driven into it. Not even their gigantic strength and tons of weight are capable of breaking through a barrier which, apparently slight, is as strong as if it were built of the tree-trunks on which the creepers are hung.

      This net is seldom used for military purposes, though I have seen one, which I believe still exists, and would do good service. In one of our largest fortresses there is a subterranean corridor, through
