But these horns, which can be used with such terrible effect in battle, are worse than useless when the animal is hampered in the net. In vain does the Oryx attempt its usual defence: the curved horns get more and more entangled in the elastic meshes, and become a source of weakness rather than strength. We see now how singularly appropriate is the passage, "Thy sons lie at the heads of all the streets, as a wild bull (or Oryx) in a net," and how completely the force of the metaphor is lost without a knowledge of the precise mode of fixing the nets, of driving the animals into them, and of the manner in which they render even the large and powerful animals helpless. The height of the Oryx at the shoulder is between three and four feet, and its colour is greyish white, mottled profusely with black and brown in bold patches. It is plentiful in Northern Africa, and, like many other antelopes, lives in herds, so that it is peculiarly suited to that mode of hunting which consists in surrounding a number of animals, and driving them into a trap of some kind, whether a fenced enclosure, a pitfall, or a net. There is, by the way, the term "snare," which is specially used with especial reference to catching the foot as distinguished from the net which enveloped the whole body. For example, in Job xviii. 8, "He is cast into a net, he walketh on a snare," where a bold distinction is drawn between the two and their mode of action. And in ver. 10, "The snare is laid for him in the ground." Though I would not state definitely that such is the case, I believe that the snare which is here mentioned is one which is still used in several parts of the world. It is simply a hoop, to the inner edge of which are fastened a number of elastic spikes, the points being directed towards the centre. This is merely laid in the path which the animal will take, and is tied by a short cord to a log of wood. As the deer or antelope treads on the snare, the foot passes easily through the elastic spikes, but, when the foot is raised, the spikes run into the joint and hold the hoop upon the limb. Terrified by the check and the sudden pang, the animal tries to run away, but, by the united influence of sharp spikes and the heavy log, it is soon forced to halt, and so becomes an easy prey to its pursuers.
