Flight is usually the first instinct of self-preservation. The zigzag start of a flight is cultivated by many besides snipe and woodcock--by hares, which bound from side to side of their line, and double back with a wonderful turn, when hard pressed; by deer pursued by wolves; by stoats when danger threatens; or by the rabbit nearly taken unawares by the spring of a cat or dog. But often a wild animal, surprised, will pause for a moment to snort or grunt, and strike the ground angrily with a fore-foot before making off--a stag for example. A stamp is a common signal or sign of annoyance, curiosity or danger. Both the weasel and the squirrel stamp impatiently with their front feet on occasions--as when they seem divided between curiosity and alarm at the presence of a motionless man. The stamp suggests an attempt to discover whether the man is friendly or hostile, alive and capable of action, or paralysed. The alarm signal given by rabbits, by striking the ground with their hind feet, produces a thumping noise, no doubt to be heard for a great distance underground. So far as danger from man goes, it is usually anticipated before it becomes pressing. Walk along a hedge within a yard of a partridge on her nest, or a leveret in its form, and no notice may be taken so long as you keep on walking. But stop, or even hesitate in your stride--the partridge or the leveret goes on the instant. Wary rooks will feed within a few yards of a man hoeing in a field--but let him stop his work, and take a look at them, and they wait for no stronger hint of danger. * * * * * The Rookery
