On lowlands such as the Coto Doñana, which is more or less level and open, the use of far-ranging rifles is necessarily restricted by considerations of safety. Obviously no shot, on any pretext whatever, may be fired either into the beat or until the game has passed clear of and well outside the line of guns. In every instance, as a gun is placed, the keeper in charge indicates by lines drawn in the sand or other unmistakable means the limits within which shooting is absolutely prohibited. The result, it follows, not only increases the prospective difficulty of the shot, but gives fuller scope to the instinctive intelligence of the game. For deer, unlike some winged game, do not, when driven, dash precipitately straight for illusory safety, but retire slowly and with extreme circumspection; all old stags, in particular, fully anticipate hidden dangers to lie on their line of flight, and narrowly scrutinise any suspicious feature ahead before taking risks. The gunner will therefore be wise to occupy the few minutes that remain available in so arranging both himself and his post as to be inconspicuous; and also in an accurate survey of his environment with its probable chances, thereby minimising the danger of being taken by surprise. The cunning displayed by an old stag when endeavouring to evade a line of guns at times approaches the marvellous. Thus, on one occasion, the writer was warned of the near approach of game by a single "clink"--a noise which deer sometimes make, probably unintentionally, with the fore-hoof--yet seconds elapsed, and neither sight nor sound were vouchsafed. Then the slightest quiver of a bough beneath caught my eye. A big stag with antlers laid flat aback, and crouching to half his usual height, though going fairly fast, was slipping, silent and invisible, through thick but low brushwood immediately beneath the little hillock whereon I lay. On examining the spot, the spoor showed that he had passed thus through openings barely exceeding two feet in height, though he stood himself forty-six inches at the withers. The feat appeared impossible.[8] [Illustration: SUSPICION] In thick forest or brushwood that limits the view it may be advisable to sit with back towards the beat, relying on ears to indicate the approach or movements of game. While sitting thus, it will occur that you become aware of the arrival of an animal, or of several animals, immediately behind you. The natural inclination to look round is strong; but 'twere folly to do so--fatal to success. This is the critical moment, when a few seconds of rigid stillness will be rewarded by a shot in the open. But that stillness must be statuesque, as of a stone god. For piercing eyes are instantly studying each bush and bough, and analysing at close quarters the least symptom of danger ahead.
