and to look for signs of spoor only occasionally. They must, however, always be alert for an abrupt change in direction. Animals usually make use of a network of paths to move from one locality to another. If it is clear that an animal was using a particular path, this can simply be followed up to the point where it forks, or to where the animal has left the path. Where one of several paths may have been used, trackers must of course determine which path that specific animal used. This may not always be easy, since many animals often use the same paths. In areas of high animal densities that have much-used animal paths which interlink, it may seem impossible to follow tracks. However, once tracks have been located on an animal path, it is often possible for a tracker to follow the path even though no further tracks are seen. By looking to either side of the path, the tracker can establish if the animal has moved away from the path, and then follow the new trail. In difficult terrain, where signs are sparse, trackers may have to rely extensively on anticipating the animal's movements. In order to move fast enough to overtake the animal, one may not be able to detect all the signs. Trackers sometimes identify themselves with the animal to such an extent that they follow an imaginary route which they think the animal would most likely have taken, only confirming their expectations with occasional signs. When trackers come to hard, stony ground, where tracks are virtually impossible to discern, apart from the odd small pebble that has been overturned, they may move around the patch of hard ground in order to find the spoor in softer ground. When the trackers lose the spoor, they first search obvious places for signs, choosing several likely access ways through the bush in the general direction of movement. When several trackers work together, they can simply fan out and quarter the ground until one of them finds it. An experienced tracker may be able to predict more or less where the animal was going, and will not waste time in one spot looking for signs, but rather look for it further ahead. Knowledge of the terrain and animal behavior allows trackers to save valuable time by predicting the animal's movements. Once the general direction of movement is established
