"_Stalking._--A Guide has to be sharp at seeing things if she is going to be any good as a Guide. She has to notice every little track and every little sign, and it is this studying of tracks and following them out and finding out their meaning which we include under the name of stalking. For instance, if you want to find a bird's-nest you have to stalk. That is to say, you watch a bird flying into a bush and guess where its nest is, and follow it up and find the nest. With some birds it is a most difficult thing to find their nests; take, for instance, the skylark or the snipe. But those who know the birds, especially the snipe, will recognize their call. The snipe when she is alarmed gives quite a different call from when she is happy and flying about. She has a particular call when she has young ones about. So that those who have watched and listened and know her call when they hear it know pretty well where the young ones are or where the nest is and so on. "_How to Hide Yourself._--When you want to observe wild animals you have to stalk them, that is, creep up to them without their seeing or smelling you. "A hunter when he is stalking wild animals keeps himself entirely hidden, so does the war scout when watching or looking for the enemy; a policemen does not catch pickpockets by standing about in uniform watching for them; he dresses like one of the crowd, and as often as not gazes into a shop window and sees all that goes on behind him reflected as if in a looking-glass. "If a guilty person finds himself being watched, it puts him on his guard, while an innocent person becomes annoyed. So, when you are observing people, don't do so by openly staring at them, but notice the details you want to at one glance or two, and if you want to study them more, walk behind them; you can learn just as much from a back view, in fact more than you can from a front view, and, unless they are scouts and look around frequently, they do not know that you are observing them. "War scouts and hunters stalking game always carry out two important things when they don't want to be seen." One is _Background_.--They _take care that the ground behind them, or trees, or buildings, etc., are of the same colour as their clothes_. And the other is "_Freezing_".--If an enemy or a deer is seen looking for them, _they remain perfectly still without moving so long as he is there_.
