Spain is a land of flocks and herds, of breeders and graziers. At the head of the scale stands the fighting-bull, monarch of the richest _vegas_; at the opposite extreme come the shaggy little ponies and brood-mares that eke out a feral and precarious subsistence in the wildest regions. Throughout the marismas hardy beasts with wild-bred progeny on which no human hand has ever laid, abound, grazing knee-deep in watery wildernesses where tasteless reed or wiry spear-grass afford a bare subsistence. There they live, splashing in the shadows, heads half-immersed as they pull up subaquatic herbage; on the back of one rides perched a snow-white egret, on another a couple of magpies, preying on ticks or warbles, while all around swim wildfowl that scarce deign to move aside. No fowler could view such a scene without perceiving that approach to the wildfowl might be effected under cover of these unsuspected ponies. The earliest aucipial mind probably realised the advantage offered, and the system has been practised in Spain from time immemorial. The method is simple. The ponies (termed, when trained, _cabrestos_, or "decoys") seem by intuition to realise what is required. By a cord attached to the headstall, the fowler, crouching behind the shoulder, directs his pony's course towards the unconscious fowl. At intervals, still further to disarm suspicion, feigned halts are made as though to simulate grazing. Before closing in, the nose-cord is made fast to the near fore-knee, thus holding the pony's head well down. Presently the ducks are within half gunshot, and we amateurs (whose doubled backs ache excruciatingly from a constrained position maintained for half an hour) pray each moment for relief and the signal to fire. No! Our fowler-friends shoot for a livelihood, and continue, with marvellous skill and patience, so to manoeuvre their beasts that the utmost possible target shall finally be presented to the broadside. There is no hurry--nor time nor aching vertebræ with them count one centimo. (See photo at p. 90.)
