In those which are made for the capture of the giraffe, the pit is very deep, and the place of the stake is occupied by a transverse wall, which prevents the feet of the captive from touching the ground, and keeps it suspended until the hunters can come and kill it at leisure. Even in Belgium and our own country the pitfall is in use. When the field-mice were devastating the districts about Liege some years ago, their ravages were effectually checked by pitfalls, in which they were caught by bushels, the pitfalls being simple holes some two feet deep, and made wider below than above. The late Mr. Waterton contrived to rid his garden of field-mice by pitfalls constructed on the same principle, though more permanent. Finding that the little animals made great havoc among his peas just as they were starting out of the ground, he buried between the rows a number of earthen pickle-jars, sinking them to the level of the ground. He then rubbed the inside of the neck with bacon, and left them. The mice stooped down to lick off the bacon, fell into the jars, and, the neck being narrow and the sides slippery, they could not get out again. * * * * * ON the left hand of the illustration is the section of a pitfall made by the well-known Ant-lion (_Myrmeleo_), of which there are several species. The history of this wonderful insect is so familiar to us that it need not be repeated at length. Suffice it to say that it digs conical pitfalls in loose sandy soil, and that it places itself at the bottom of the pit, securing the insect victims with its jaws just as the larger animals are secured by the stake of the human hunter. It makes no false cover, as does the human hunter, but it always chooses soil so loose that if an insect approach the edge, the sand gives way, and it goes sliding down into the pit, whence its chance of escape is very small, even were there no deadly jaws at the bottom ready to receive it. THE CLUB. The simplest of all offensive weapons is necessarily the CLUB. At first, this was but a simple stick, such as any savage might form from a branch of a tree by knocking off the small boughs with a stone or another stick. Such clubs are still used in Australia, and I have several in my collection. Then the inventive genius of man improved their destructive power by various means. The most obvious plan was to add to the force of its blow by simply making one end much thicker and heavier than the other. This is done in the “Knob-kerry” of Southern Africa, and it is worthy of remark that in Fiji a weapon exists so exactly like the short knob-kerry of Africa, that an inexperienced eye would scarcely be able to distinguish between them.
